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.

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.

Avadi taluk, by centroid in taluk.

stage of extraction, taluktaluk projection

Groundwater drawn each year as a share of what recharges, for the whole taluk. Above 100 is more drawn than recharges.

Avadi
containing revenue taluktaluk projection

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. 6 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.

6 water bodies cover 18.1 ha here, the largest of them 15.2 ha. The register names 3 of them; the names and polygons are not shown on this page.

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

207 samples between 2022-08-18 and 2026-08-25. 183 were taken at a source and 24 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.

Sources through the summer

Census 2011, reference year 2009.

5 source types were recorded for the year and 5 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 is missing

16 of 40 capabilities are supported by acquired evidence. The rest are named here rather than left blank.

Named gap
No source carries it (11)

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
Named gap
Not determined whether it applies here (13)

These may not be meaningful for an inland rural Panchayat. Until that is decided, they are neither claimed nor dismissed.

  • surface water change
  • 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
