What each page shows for Jaipur
Dashboard - a city that drinks a dam 120 km away
77% of Jaipur's piped water comes from one dam. The state's Public Health Engineering Department (PHED), not the municipal corporation, supplies the city. Its Annual Progress Report 2025-26 (status 31 December 2025, printed p.85, in Hindi) puts the city's production at 766.73 MLD: 590 MLD from Bisalpur dam on the Banas, about 120 km away, and 176 MLD from 3,633 PHED tube wells. A year earlier Bisalpur gave 492.08 MLD and the tube wells about the same 176, so the whole rise of about 98 MLD came from the dam.
That is why the dashboard opens on the supply chain rather than a reservoir countdown: from the dam, through the Surajpura treatment plant and the Balawala pumping station at the city's edge, to PHED's 590,385 water connections. PHED's zone schedule of 15 April 2024 gives most colonies about an hour of water a day. At the 2025 summer peak, on 24 June, PHED ran 230 tankers a day making 1,283 trips in the city; the dashboard carries that peak.
What is not published: the city's share, its losses and its plant capacity
No allocation order. Bisalpur also supplies Ajmer, Tonk and the villages along both pipelines, and irrigates the land below it. A Water Resources Department study of February 2020, published by the World Bank, describes 11.1 TMC (thousand million cubic feet) a year for Jaipur and the villages on its pipeline, 5.1 TMC for Ajmer and about 8 TMC for irrigation. That is a description, not an order, and no order fixing Jaipur's share has been found.
No city-wide loss figure. The last published figure for water lost between source and tap is 37% in 2015, on PHED's figures in JICA's evaluation of the Bisalpur project, which warned it was likely unreliable because a 2014-15 study had found 45 to 81% of consumer meters out of order in four zones. In January 2025 PHED gave 44.2% in Bajaj Nagar and 27% in Chitrakoot, two of its round-the-clock trial areas, against a target of 20%; its January 2026 report gives no current figure. So the dashboard carries no non-revenue water figure for the city.
No treatment-capacity figure. PHED's project list names a 200 MLD plant at Surajpura, but that is one stage, and no primary source we have found gives the capacity of the whole works. So the dashboard shows what PHED produces, not what its plants can treat.
Figures shown exactly as PHED printed them
PHED's reports are printed in Hindi in an old typeface that does not copy as text, so every figure was read from the page images. The tube-well count and output are the same in the 2024-25 and 2025-26 reports; they are shown as printed. Private borewells appear in no PHED figure.
Reservoir cards - and why there is no days-of-water-left number
The dashboard carries two dams: Bisalpur, the city's main source, and Ramgarh, its old one. Bisalpur is not the city's own storage. Its water is shared by Jaipur, Ajmer, Tonk and irrigation, and no order says how much of it is Jaipur's. Dividing the dam by the city's draw would credit Jaipur with water that belongs to other towns and to farmers, so no days-left figure is computed and Bisalpur's card is labelled shared.
The readings come from the Rajasthan Water Resources Department's dam storage report, which covers all 693 of the state's dams. It is published daily from mid-June to mid-October and on the 1st and 16th of other months, often weeks late. A row is accepted only if its printed percentage equals its storage over the dam's designed capacity, so a misread column fails instead of writing a wrong number; a figure the department's neighbouring reports contradict is held back, not corrected. Storage reports go back to May 2025 and the department's monsoon rainfall bulletins carry the same table back to 16 June 2023, so the history runs from there. Earlier weekly points for Bisalpur come from the Central Water Commission's bulletin.
On 8 October 2026, the latest report, Bisalpur stood at 313.90 m and held 781.41 million cubic metres, 71.31% of what it was built to hold. On the same date a year earlier it was full.
Two percentages that are never joined
The state's report gives gross storage, all the water behind the dam, as a share of its designed capacity; it publishes no usable (live) storage. The Central Water Commission's weekly bulletin gives live storage, which leaves out the water below the lowest outlet, against a different capacity (1.076 billion cubic metres for Bisalpur). The two measure different things: CWC put Bisalpur at 59.39% on 8 May 2025, and the state's report at 57.87% on 16 May 2025. The cards show only the state's percentage, and CWC's weekly rows keep their volume with the percentage left blank.
Ramgarh, empty in two very different years
The department reported Ramgarh at zero on 8 October 2026, and at zero on the same date in 2025, when the state's dams as a whole were 90.38% full (61.80% in 2026). It reported the dam empty on every date read, June 2023 to October 2026. Ramgarh was a source of the city's drinking water from 1978, as the Supreme Court recorded in 2017; its card stays on the dashboard so the absence can be seen. The report's 19.82 m for Ramgarh is a gauge reading, not a full-tank level, so the card shows none.
Groundwater - the city has its own unit, and it is the most over-drawn
The groundwater map shows Jaipur district's 16 assessment units in the national groundwater assessment (IN-GRES), five editions from 2021-2022 to 2025-2026, drawn on IN-GRES's own unit boundaries. The measure is the stage of extraction: how much of the groundwater that refills each year is pumped out.
In 2021-2022 IN-GRES carved a Jaipur Urban unit out of the Sanganer, Amber and Jhotwara blocks, and about 96% of the city's outline lies inside it. In 2025-2026 it stands at 349.88%, over-exploited: the city draws about three and a half times what can be taken each year without depleting the aquifer, the highest of the district's units. All 16 units are over-exploited, and the district as IN-GRES assesses it reads 210.41%. About four fifths of the city unit's draw is domestic and none is irrigation; across the district about 72% is irrigation. Rajasthan's printed 2025 report carries the 2024-2025 edition, 328.41% for Jaipur Urban; the map leads with the newer edition.
Read the category, not a trend
Several inputs are carried forward from one edition to the next, so the change between editions is not a measurement. Industrial use in Jaipur Urban is entered as 244.81 hectare-metres in four editions and 826.39 in 2025-2026, which accounts for most of that edition's rise. Recharge is credited from rainfall only, and the unit's rainfall is copied from Jhotwara Rural's. The page quotes the category and the latest stage, and does not draw the series as a trend. IN-GRES also still draws the district as it was before 2023, so the district total includes Kotputli, Viratnagar, Paota and Dudu.
The dots on the map are 148 telemetry wells: 108 run by the Rajasthan Ground Water Department and 40 by the Central Ground Water Board, read every six hours on the National Water Data Portal and shown as monthly means from January 2021. 16 of them stand in the Jaipur Urban unit. Each well is placed by its coordinates, not by the district it is tagged to, because the tags follow the district's lines before 2023. PHED's own draw is the 176 MLD from its 3,633 tube wells; private borewells appear in no published figure.
Why there is no ward-by-ward depth map
Shallow and deep piezometers stand side by side: the Board's Durgapura well reads about 8 m below ground and its Mansarovar well about 42 m. A depth surface drawn across the city would average different aquifers into one number, so the page shows the wells themselves. (That Durgapura well is not the 100 m Durgapura piezometer in the Board's yearbooks, a different well of the same name.)
The readings need care. The state's series uses 999.0 as a placeholder, and zeros and sign flips occur; months with no reading that passes the checks are left blank, never set to zero. About 70 state wells report only from 27 July to 3 September 2026. Jaisingpur Khor's record rises from about 56 m below ground in mid-2024 to under 15 m, a rise the portal does not explain, so read its latest depth with care.
The rules that apply here. Groundwater in Rajasthan is still regulated by the Central Ground Water Authority: the 2023 amendment to its guidelines (S.O. 1509(E), 29 March 2023) lists Rajasthan among the states it regulates. Because every unit in the district is over-exploited, its guidelines (S.O. 3289(E), 24 September 2020) give no permission to draw groundwater for a new industry other than a micro, small or medium enterprise, and none for a new packaged drinking-water plant; water tankers need a permission and pay Rs 35 a cubic metre. Under the Jaipur Development Authority's Building Regulations 2025 (regulation 8.3), every plot of 225 square metres or more must have a rainwater harvesting structure. Rajasthan's own Ground Water (Conservation and Management) Authority Act was passed in September 2025 and published in the Gazette on 8 October 2025; it takes effect only on a date the state notifies, and no such notification had been found by 20 October 2026.
Rivers - clean at the source, no readings on the city's own river
The rivers page draws four rivers: the Dravyavati through the city, the Dhund it flows into, and the Banas and the Banganga at the city's two dams, Bisalpur and Ramgarh. The water quality is the Central Pollution Control Board's (CPCB) annual readings, 2018 to 2024, each year's lowest and highest value as CPCB printed it; nothing is averaged or filled in.
The finding is a contrast. At Bisalpur (station 2951), where the city's water comes from, the highest BOD (a measure of organic load) was 1.6 mg/L in 2024, and within CPCB's bathing criterion of 3 mg/L in five of the seven years. At Newta dam (station 2952), which takes water diverted from the Dravyavati through a channel from Gular dam, the highest BOD was above 3 mg/L in every year from 2018 to 2024, and 36.5 mg/L in 2024. Kanota dam on the Dhund (station 4781) has one year of readings, 2021: BOD 2.0 to 5.2 mg/L.
The Dravyavati is the city's own river. The Jaipur Development Authority's (JDA) 2017 environmental report calls it “the active river of Jaipur which, over the time turned into a Nallah (Amanisha Nallah)”. JDA's contract of 18 March 2016 was to design and build a 47.50 km corridor for Rs 1,470.85 crore, with Rs 206.08 crore for ten years of upkeep, as the Rajasthan High Court recorded in its order of 19 December 2024. OpenStreetMap maps the river as the outline of its channel, not a centre line, so the length of the drawn line would be a perimeter; the page uses JDA's 47.50 km.
No readings on the Dravyavati's channel
No agency publishes water-quality readings on the channel itself. The Newta dam series is shown under the Dravyavati and named as indirect: the Rajasthan State Pollution Control Board's (RSPCB) 2018 action plan says the dam “is fed from Dravyavati River through a diversion channel”, so the readings show the water the river sends there, not the channel. The treatment-plant panel is off: RSPCB publishes monthly sample counts rather than results, and CPCB's 2024 table of drains and sewage plants has no Rajasthan rows.
One station shown without its location
CPCB's station list (October 2020) places station 2952 at 26.919491 N, 75.930328 E, which is Kanota dam on the Dhund, 0.37 km from station 4781, while RSPCB's 2018 plan maps Nevta dam south-west of the city. Where the samples are taken is not settled, so the readings are shown and the map marker is not. Jal Mahal (station 2944) is a lake, not on a river this page draws, and is left out.
Three polluted-stretch editions, three different names
CPCB has listed this stretch in each of its three polluted-stretch editions, under other names: the Banas ‘along Bisalpur Dam, Swaroopganj, Newta Dam’, Priority III (2018); the Banas ‘Bassi to Bisalpur’, Priority I (November 2022), on 35.7 mg/L, the same figure as Newta dam's highest in 2019, when Bisalpur's highest was 1.7; and the ‘Vishwamitri near Newta Dam’, Priority II (2025). The 2025 report pairs Newta dam's 16 mg/L with a reading at Khalipur village that the same report lists under Gujarat; Newta dam's own figure falls in CPCB's Priority III band. All three are shown with their dates. CPCB's website policy requires its approval for any use beyond download and print, so its reports are cited here, not copied.
Flood risk - rain on the city, not a river in spate
The flood-risk page is a written record, not a map. The district disaster management plan of 2025 says flooding in the district “is of minor nature”: low-lying parts of the city are waterlogged in the monsoon, “largely due to inadequate drainage”. It names 1981 and 2012 as the years heavy rain flooded the city. The heaviest day on the India Meteorological Department's (IMD) record for Jaipur is 326.0 mm on 19 July 1981, in a month of 956.9 mm, more than one and a half times a normal year (600.3 mm). Jaipur district's June to September rain was 986.6 mm in 2024 and 918.5 mm in 2025, 88% and 75% above the normal of 524.3 mm.
The page sets no trigger. The Central Water Commission has no gauge in the district (the nearest are at Tonk and the Bisalpur inflow, both on the Banas), the district plan sets no numeric threshold, and we have not found the rainfall the city's drains are designed for. IMD's ‘very heavy’ band (115.6 to 204.4 mm in a day) is quoted only as context on the 2012 entry. The Dravyavati project's stated aim, in JDA's 2017 report, is to pass a hundred-year flood; the High Court's order of 19 December 2024 records that no channel was built in the submergence areas of three dams along it, at Sikar, Gular and Ramchandrapura. Damage figures appear only where an official document gives them, and none does for the city.
What is not public yet
The list of waterlogging spots: the plan says the city's low-lying pockets ‘have been identified’ and that pumps are placed there by the first week of June, but it does not list them. A flood map of the city, modelled or drawn from past events. The rainfall the drains are built for. A water-level gauge on the Dravyavati or the Dhund. And damage figures for the city: the relief department counts rain deaths for Rajasthan as a whole (133 in the 2024 monsoon, 193 in 2025), not by district.
IMD's two figures for 1981 as a whole disagree (1,403.9 mm in its 1991-2020 tables, 1,180 mm in its ‘Climate of Jaipur’ booklet), so the page uses only July 1981, on which both agree.
Water bodies - from OpenStreetMap, because no city lake register is published
The water-bodies map draws 36 lakes, ponds and reservoirs from OpenStreetMap, in a box wider than the corporation, because the city's main dams (Ramgarh, Kanota, Nevta and Chandlai) lie outside it. Rivers are drawn on the rivers page instead. We have not found a lake register or lake layer published by Nagar Nigam Jaipur or JDA, so the map rests on OpenStreetMap, whose shapes anyone can edit.
Three of the 36 are not lakes
The download cannot tell them apart from lakes, so three shapes on the map are not water bodies in the usual sense: the ‘Amanishah Nala’ polygon, a stretch of the Dravyavati's channel that is also drawn on the rivers page; a building-material pit; and a fountain. They are named here rather than removed by hand. Ramgarh is mapped at about 113 hectares, against the 1,035 hectares of reservoir area in the national dam register, so its shape shows where the dam is, not how far it spreads when full.
The national census did not reach the city
The Ministry of Jal Shakti's first Census of Water Bodies (reference year 2017-18) counts 82 water bodies in Jaipur district, all of them rural and almost all in Shahpura and Phulera tehsils; it recorded no urban water body in the district, and Amer is the only tehsil near the city it reached. The second census (reference year 2023-24) counts 14,400 in Rajasthan, 1,081 of them urban, but its district tables were not on the Ministry's table page on 20 October 2026.
The ward search, the ranking and the lost-lake list are off: there is no digital ward map to search by, and no official register to rank or to count losses from. The ground-height bands and the catchment and cascade view have not been built for Jaipur yet.
Lake restoration - mostly a court record
The lake-restoration page carries eight water bodies: Mansagar (Jal Mahal), Ramgarh, Kanota, Nevta, Chandlai, Talkatora, Maota and Kukas. Each is graded V where it is checked against a primary document and N where it rests on a single source. Storage figures are the Water Resources Department's of 8 October 2026: the 27 dams it gauges in the district held 16.3% of their designed capacity that day, against 61.80% for the state, and eleven held nothing.
Seven programmes and seven court and tribunal orders sit beside them, from the High Court's 2004 directions on Ramgarh's catchment to its orders of July and August 2026. Mansagar was restored by JDA under the National Lake Conservation Plan (Rs 24.72 crore, approved in 2002) and its shore leased for a tourism project, a lease the Supreme Court cut to 30 years in 2014. On 28 February 2025 the Court recorded a forest officer's report that the lake “has been completely damaged” and directed a study by NEERI. Ramgarh's catchment has been before the Rajasthan High Court since 2011; on 13 August 2026 the Court ordered the District Collector's list of encroachers published in two newspapers. A Rajya Sabha answer counts 405 renovations of traditional water bodies in Jaipur district between 22 March 2025 and 12 March 2026, without naming the scheme or the water bodies.
Where a figure rests on a party's submission rather than a court's finding, the text says so. Orders are read from the court-signed copies that LiveLaw and Verdictum publish, and cited by court, case number and date, because the courts' own case search sits behind a search form.
Which Chandlai?
The department's report has two rows named Chandlai, one in Jaipur district (2.04 million cubic metres designed) and one in Tonk district (4.53). Which of them is the 122-hectare Chandlai lake OpenStreetMap maps south of the city is not settled. The Jaipur row's storage never leaves 1.99 to 2.04 million cubic metres in the reports read, so it reads full or nearly full in every season; the card shows it as printed.
Held back, and why
Sagar and Galta are not shown: no official record of their present state was found. For Kukas the national dam register gives 43.75 million cubic metres gross but 4.375 million effective, which cannot both be right, so neither is published; the card uses the department's 1.926. We have not found a public register of the lakes Jaipur has lost, so the page carries the lakes that exist and the work on them, not a count of those that are gone.
My Ward - a ward table, because there is no digital ward map
My Ward covers Nagar Nigam Jaipur's 150 wards, set by the state's ward notification of 16 September 2025 (Rajasthan Gazette, 20 September 2025) after the Greater and Heritage corporations were merged back into one. Each ward shows its zone (13 in all), its assembly seat (10) and its population as the notification gives it: 3,197,135 across the city, between 13,499 and 32,272 a ward. The notification does not say which census the figures come from. Zone office lines and emails come from the corporation's administrative directory and are shown for the 8 zones that list them.
For water, the page points to PHED: its Jaipur district control room, its City Circle North and South offices, and Rajasthan Sampark (181), the state's grievance line, because the corporation's Jaipur Samadhan portal has no water category. Jaipur Samadhan and the corporation's call centre are listed for civic complaints, and 1077 for floods. No councillor names or parties are shown, and no officer's mobile number.
Why there is no map, and nothing placed ward by ward
The official 2025 ward map is a picture without coordinates, and no digital boundary file has been published. The ward files in circulation are older: one covers only the former Greater corporation's wards, another is a 2019 proposal. Without boundaries, lakes, flooding, drains, wells and river stations cannot be placed in a ward, so My Ward links to the city-wide pages for them. No published map says which PHED circle serves which ward, so both circle offices are listed.
Commitments - twenty-one dated promises
The commitments page tracks 21 promises about Jaipur's water supply, new sources, sewers and drains, the Dravyavati and Ramgarh, each on a dated document: PHED's annual progress reports, the State's budget speeches, the Ministry of Housing and Urban Affairs' AMRUT 2.0 progress report, a National Water Development Agency note, or a court order. Four are delivered: two later than the date PHED or JDA had set, one ahead of it, and one that never had a published date. Four are past their date with no completion on record: Stage II Phase I of the Bisalpur-Jaipur project (due 31 March 2025, then 31 March 2026), the second stage of the Prithviraj Nagar works (due 12 August 2025, then March 2026), the Jagatpura, Pratap Nagar and Mahal Road works (due March 2025), and round-the-clock supply in five trial areas. For the last, the date is our reading of ‘in the next two months’ in PHED's January 2025 report, and the page says so.
For the other thirteen the promise can be cited but its current status cannot yet be cited either way. Most are budget announcements with no date, among them Stage II Phase II of the Bisalpur-Jaipur project for Jaipur and Ajmer (Rs 1,986.68 crore), the Brahmani-Bisalpur link (an estimated Rs 6,100 crore) and the Ram Jal Setu link, in none of which is Jaipur's own share stated. The AMRUT 2.0 report still names the two former corporations, and its rows keep those names. A status changes only against a dated document; the register is re-checked each January against PHED's report, each February against the budget, monthly against the AMRUT 2.0 report, and after the High Court's hearings on Ramgarh and the Dravyavati.
Facts and rainfall
The facts page is 16 cards, each read from the data behind the page it summarises or from the document it cites, and four of them lead the dashboard. One card is a gap: how much sewage the city makes, for which no city figure has been found. Another gives the last published figure for water lost in the pipes, from 2015.
Rainfall comes from IMD's 0.25-degree gridded record, 1970 to 2025, at the grid cell at 26.75 N, 75.75 E. We checked the choice. The cell contains IMD's Jaipur (Sanganer) observatory, station 42348, whose 1991-2020 normal is 600.3 mm a year; the cell gives 591.9 mm over the same years, 1.4% lower, while the cell to the north, which covers more of the city, gives 612.7 mm, 2.1% higher. Its 1970-2020 average is 611.2 mm, 68% of it in July and August. Months after IMD's last published month (December 2025) are filled from Open-Meteo's reanalysis and marked provisional until IMD catches up.
The provisional months read low this year
From 1 June to 8 October 2026 Open-Meteo gave 383.4 mm at this cell, against 527.9 mm at IMD's airport gauge as the Water Resources Department's rainfall report prints it, about 27% less. The fill is kept because it is the method every city on the platform uses, and IMD's own figures replace it when they are published.
Origins - from wells inside the walls to a dam 120 km away
The origins page tells the city's water history in eight chapters: Amer, the hill capital before the city, and its lakes; the planned city of the 1720s and its wells, of which, in 1880, only 49 of the 827 inside the walls held pure water, by T. H. Hendley's account of 1895; the steam pumps on the Amanishah from 1874 and pipes from December 1875; Ramgarh, built for fields and later the city's reservoir; the lake that stopped filling; water from the Banas; Mansagar and the Dravyavati; and the dam far away and the aquifer below today.
It is as careful about what it leaves out. There is no single founding year, because the Imperial Gazetteer gives 1728 and later accounts 1727; no year for the Mansagar dam or Jal Mahal; no single completion year for Ramgarh (1901 in the national dam register, 1903 in the Supreme Court's judgment); and no date for Bisalpur water first reaching the city, because none was found. Every image carries its licence, checked at source.
What is not here, and why
Each absence below is a decision with a reason, recorded in the repository so that an omission is never mistaken for a bug.
No allocation ledger
The ledger compares what a city is entitled to with what it receives, and no public order states Jaipur's share of Bisalpur dam. The Water Resources Department's 2020 study describes 11.1 TMC a year for Jaipur and the villages on its pipeline, but a description is not an allocation order. PHED's draw by source is on the dashboard instead.
No tanker page
PHED publishes summer tanker totals for the city (230 tankers making 1,283 trips a day at the June 2025 peak) but no register by area, month or price. The totals are on the dashboard.
No shoreline or climate-risk page
Jaipur is landlocked, so there is no coastline. The climate-risk page is not built: the state's only climate plan (2014) gives state-wide projections, and the sub-basin risk surface the page needs has not been run for the Banas or the Banganga.
Intelligence & AI narratives
Daily AI briefings, longer-form weekly narratives, and per-ward AI profiles are pending for Jaipur - the underlying summary stores aren't yet multi-city. Until those land, the page surfaces raw data without an AI commentary layer.
Data sources for Jaipur
All operational data is collected by the Python pipeline and supporting scripts that power the dashboard. Raw source data and Earth Engine summaries are upserted into Supabase (PostgreSQL) and then exposed as small, readable product signals.
Supply and reservoirs
The Public Health Engineering Department's own account of the city's supply: 766.73 MLD on 31 December 2025, 590 from Bisalpur and 176 from 3,633 tube wells (2025-26, printed p.85), the year before (2024-25, p.84), connections, the summer tankers (Appendix 7, pp.41-42) and the round-the-clock trial areas; and, per project, sanction, spend, percent done and target date, the basis of most of the commitments page. The zone schedule (status 15 April 2024) gives the hours of supply. Printed in Hindi in an old typeface, so figures are read from the page images. The site's copyright policy allows reproduction free of charge with the source prominently acknowledged.
The 'Water Storage Data' report for all 693 of the state's dams: designed level and capacity, that morning's level and gross storage, its percentage of designed capacity, and last year's storage. Behind the dashboard's Bisalpur and Ramgarh cards, the storage history and the lake-restoration storage figures. Each report is a PDF, read row by row, and a row is kept only if its printed percentage checks out. Storage reports run from May 2025, and the monsoon rainfall bulletins carry the same table back to 16 June 2023. The department publishes no live storage and states no reuse licence; its terms say the content should not be taken as a statement of law. Cited with attribution.
Bisalpur's weekly live storage, used only for the history before the state's daily record begins. CWC counts live storage against 1.076 billion cubic metres, a different base from the state's gross storage, so its rows keep their volume and leave the percentage blank. The listing stops at the bulletin of 8 May 2025. CWC asks for permission before reproduction; cited, not republished.
The design record of the dams behind the city: Bisalpur (completed 1999) and its position, Ramgarh (1901, 75 million cubic metres, a reservoir area of 1,035 hectares), Kanota on the Dhund (2001), and Kukas, whose two capacities in the register disagree and are not published.

Weather and rainfall
Grid cell 26.75 N, 75.75 E, 1970 to 2025. The cell contains IMD's Jaipur (Sanganer) observatory, station 42348: it gives 591.9 mm over 1991-2020 against the observatory's normal of 600.3 mm (1.4% lower), and the cell to the north 612.7 mm (2.1% higher). IMD data policy; cited with attribution.
Reanalysis daily rainfall at the same cell, filling the months after IMD's last published month and marked provisional until IMD's own figures replace it. From 1 June to 8 October 2026 it read about 27% below IMD's airport gauge (383.4 mm against 527.9 mm). CC BY 4.0.
The observatory's normal (600.3 mm a year on 34.3 rainy days, printed p.166), its monthly normals, and the heaviest day on record, 326.0 mm on 19 July 1981. Used for the check on the grid cell and on the facts and flood-risk pages. Government of India publication, cited with attribution.

Groundwater
The national Dynamic Ground Water Resource Assessment for the district's 16 units, five editions from 2021-2022 to 2025-2026, drawn on IN-GRES's own 2021 unit boundaries: Jaipur Urban at 349.88% in 2025-2026, every unit over-exploited. The 2024-2025 district figures equal Rajasthan's printed 2025 report (p.168). IN-GRES states no terms of use or licence; cited with attribution.
Six-hourly readings from 148 piezometers in the district, 108 run by the Rajasthan Ground Water Department and 40 by the Central Ground Water Board, shown as monthly means from January 2021. Wells are placed by their coordinates, because the portal's district tag follows the lines before 2023, and placeholders (999.0), zeros and sign flips are screened out.

Water bodies and restoration
The 36 lake, pond and reservoir shapes on the water-bodies map and the four rivers on the rivers page, because no city lake register or lake layer is published. Three of the 36 are not lakes (the Amanishah Nala polygon, a building-material pit and a fountain), and the Dravyavati is mapped as its channel's outline. ODbL 1.0.
The first census (reference year 2017-18) counts 82 water bodies in Jaipur district, all rural, none recorded as encroached; its unit rows on the Open Government Data Platform describe Maota and Kukas. The second (2023-24) counts 14,400 in Rajasthan, 1,081 of them urban, with no district tables yet. Government of India publication, cited with attribution.

Rivers and pollution
Annual river tables: Bisalpur dam (2951) and the river near Newta dam (2952) for 2018-2024, and Kanota dam (4781) for 2021, each year's lowest and highest value as CPCB prints it, with page numbers; and CPCB's station list of October 2020, whose coordinate for 2952 sits at Kanota and is withheld. CPCB's 2025 river file covers the Yamuna only. CPCB's website policy requires its approval for any use beyond download and print, so its reports are cited here, not copied.
The three classes given to the stretch at Newta dam, each under a different name: Priority III (2018), I (2022) and II (2025). The 2022 list is read from a Lok Sabha answer of 5 December 2024, and the 2025 report from a copy hosted by the Puducherry Pollution Control Committee. CPCB's website policy requires its approval for any use beyond download and print, so its reports are cited here, not copied.
The Rajasthan State Pollution Control Board's plan for the state's polluted stretches: Nevta dam 'is fed from Dravyavati River through a diversion channel' from Gular dam, and its map places the dam south-west of the city. Why the Newta readings are shown under the Dravyavati, and why their marker is withheld. Government of Rajasthan publication, cited with attribution.
Lists Jaipur's sewage plants one by one, several marked under construction or proposed, with a state figure but no city total, so the facts page's sewage card is a gap. CPCB's website policy requires its approval for any use beyond download and print, so its reports are cited here, not copied.
Flood and civic infrastructure
The district plan's flood chapter (flooding 'of minor nature', waterlogging 'largely due to inadequate drainage', 1981 and 2012, pumps placed by the first week of June) and its control room; the State Disaster Management Plan of 2014 on the floods of 1981; the Flood Action Plan 2024; and the department's yearly reports, which give rain deaths for the state as a whole. Government of Rajasthan publication, cited with attribution.
Linked from the flood-risk page for context only: there is no station in Jaipur district. The nearest are the base station at Tonk (warning level 262.0 m, danger level 262.8 m) and an inflow forecast for Bisalpur, neither of which measures water in the city.

Data quality & limitations
How we classify river health
CPCB publishes two parallel river-water-quality classification systems, and they don't always agree. Knowing which one we use - and why - matters for reading our river status badges honestly.
Designated Best-Use classes (A-E)
Computed from current dissolved-oxygen, BOD and coliform thresholds at each monitoring station. Updates every reading. Class A = drinking with disinfection only; Class B = outdoor bathing; Class C = drinking with conventional treatment; Class D = fisheries/wildlife; Class E = irrigation only. Below E = practically dead.
Polluted River Stretch (PRS) Priority I-V
A historical, multi-year stretch-level designation reflecting cumulative pollution. Slow to update; once a river stretch is on the Priority list it tends to stay there even if recent readings improve. Priority I = worst (BOD > 30 mg/L sustained); Priority V = least bad of the polluted stretches.
Our status badges ("dead", "severely degraded", "degraded", "stressed", "healthy") are computed from current readings via the Designated Best-Use thresholds - not from the PRS Priority list. We take the worst classification across a river's monitored stations and surface that as the river-level status.
Practical consequence: a river on CPCB's PRS Priority list won't automatically render as "severely degraded" here. If the underlying readings show only Class C/D conditions, the badge reflects that. The PRS designation belongs in the river description as historical context, not as the live status.
Status thresholds follow CPCB's published Designated Best-Use criteria; readings are from CPCB NWMP annual River Water Quality reports.
Known Limitations
- Source feeds may occasionally be stale (weekends, holidays, portal outages). Each surface shows a freshness indicator.
- Groundwater data may lag by months or years. The map always shows the most recent available period.
