Gram Panchayat|LGD 228400Reviewed brief
Poondi
Part of Ammapet block, Thanjavur district, in the Cauvery Delta sub-basin. Reviewed by a person on 2026-07-25.
Drinking-water service is well documented; present-day irrigation reliability is not.
JJM lists a tap connection for every recorded household and recent programme sampling. Census records show strong historical dependence on canals, while Saliyamangalam firka is classified Semi Critical. The missing link is current irrigation: the available records do not show whether today’s paddy area receives dependable canal water or is shifting pressure onto groundwater.

Place and boundary
The mapped extent comes from the TNGIS Panchayat polygon for this LGD code, so the place on the map is the place the records describe.

Habitations
JJM records service for each habitation separately. A Panchayat total can hide a habitation that is behind.
| Habitation | Population | Households | Tap connections |
|---|---|---|---|
| Periyaar Nagar | 1,094 | 205 | 205 |

Where the water comes from
The schemes JJM records as serving this Panchayat, grouped by the kind of source they draw on.
| Source | Category | Count |
|---|---|---|
| Deep Tubewell | Ground Water | 8 |
Groundwater, projected from the taluk
IN-GRES assesses revenue taluks. This Panchayat inherits its containing taluk's category unchanged, as containing-area context rather than a measurement of the place.
Papanasam taluk, by centroid in taluk.
Groundwater drawn each year as a share of what recharges, for the whole taluk. Above 100 is more drawn than recharges.
Sub-district on the revenue hierarchy, which the Panchayat hierarchy does not nest inside.
The assessment unit is a revenue taluk, not the Gram Panchayat: each Panchayat inherits its containing taluk's category and stage of extraction unchanged, as containing-area context rather than a measurement of the place. Containment is decided by the TNGIS polygon centroid (vertex fallback for concave polygons); a Panchayat that falls in no taluk or in a taluk without an assessment is deferred, never guessed. 8 TNRD blocks span more than one revenue taluk, so a block-to-taluk name match would have been wrong.
Tanks and water bodies
Mapped by TNGIS and assigned to this Panchayat by the register itself, not by a name match.
24 water bodies cover 46.7 ha here, the largest of them 8.1 ha. The register names 20 of them; the names and polygons are withheld pending the TNGIS licence reply.
Waterspread is the mapped extent, not storage. It says nothing about whether these hold water through the year, whether they are encroached, or when any one of them was last surveyed.

Water-quality testing
94 samples between 2022-12-05 and 2026-07-16. 45 were taken at a source and 49 at households.
None was recorded unsafe. A clean run this long describes the reporting as much as the water, so read it as an absence of recorded failures rather than as evidence of safety.

Land and irrigation
Census 2011, reference year 2009. A historical baseline, not current cropping.
of 711.53 ha total.
canal 425.08 ha, wells 7.89 ha, tanks 0 ha.
culturable waste; barren 0 ha, forest 0 ha.
Sources through the summer
Census 2011, reference year 2009.
4 source types were recorded for the year and 4 held through the summer months. None failed.
This is the 2009 pattern and says nothing about whether today’s piped supply holds through summer.
What this means here
Read by a person against the records above, on 2026-07-25.
Administrative identity
Poondi is recorded as LGD Gram Panchayat 228400 and JJM Gram Panchayat 152086; the Census record covers settlements 638660 and 638661.
Drinking-water service
JJM displays 1,143 households and 1,143 tap connections across three habitations, eight deep-tubewell source rows, 94 sample rows, and a latest displayed Safe sample dated 2026-07-16.
Land and irrigation baseline
The 2009 Census baseline totals 711.53 ha, 438.98 ha net sown, and 432.97 ha irrigated; 425.08 ha of the irrigated area is recorded as canal irrigation.
Current crop signal
Summer 2025 AgriNet rows show 332.2 ha across Poondi-1 and Poondi-2, chiefly paddy, but current irrigation method remains unknown.
Groundwater pressure
Saliyamangalam firka is Semi Critical at 85.8 percent in the 2024 groundwater assessment.
What is missing
15 of 40 capabilities are supported by acquired evidence. The rest are named here rather than left blank.
Nothing acquired for this district answers these, so they are named rather than estimated.
- drinking water reliability
- groundwater level observation
- groundwater level trend
- aquifer context
- catchment context
- water body condition
- waterway network
- flood hazard
- observed flood events
- natural drainage
- wastewater service
These may not be meaningful for an inland rural Panchayat. Until that is decided, they are neither claimed nor dismissed.
- surface water change
- river water quality
- engineered stormwater drainage
- wastewater treatment assets
- pollution pressure inventory
- measured water pollution
- coastal and estuarine
- current crop and irrigation state
- soil water context
- agricultural water system relation
- crop water demand
- agricultural water stress observation
- agricultural water pollution pressure
- composite priority score
What would sharpen this
- Which canal and command area currently serve Poondi?
- Which nearby rain gauge best represents local seasonal conditions?
- How much of today’s cultivated area depends on canals, wells, or both?
- Where do the Panchayat boundary, drainage paths, flood-prone areas, and water bodies lie?
