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.

4 water bodies cover 328.1 ha here, the largest of them 288.3 ha. The register names 4 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

842 samples between 2022-11-28 and 2026-08-10. 775 were taken at a source and 67 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.

What is missing

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

Named gap

No source carries it (12)

Nothing acquired for this district answers these, so they are named rather than estimated.

drinking water reliability
historical water access
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 (14)

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
historical agricultural baseline
current crop and irrigation state
soil water context
agricultural water system relation
