Deep Tubewell, Open Well
Kolli Hills is assessed safe. This describes the taluk, not this Panchayat.
30 rain days between 2026-08-07 and 2026-09-06, modelled rather than gauged.
Safe on 2026-05-05. 123 samples over 5 years, none of them recorded unsafe.
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.

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 |
|---|---|---|
| Open Well | Ground Water | 18 |
| 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.
Kolli Hills 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. 4 TNRD blocks span more than one revenue taluk, so a block-to-taluk name match would have been wrong.
Water-quality testing
123 samples between 2022-11-25 and 2026-05-05. 109 were taken at a source and 14 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.
| Year | Samples |
|---|---|
| 2022 | 16 |
| 2023 | 18 |
| 2024 | 19 |
| 2025 | 50 |
| 2026 | 20 |
Land and irrigation
Census 2011, reference year 2009. A historical baseline, not current cropping.
of 1,080 ha total.
canal 0 ha, wells 0 ha, tanks 0 ha.
culturable waste; barren 108.96 ha, forest 384.3 ha.
Sources through the summer
Census 2011, reference year 2009.
6 source types were recorded for the year and 6 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
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 inventory
- 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
- 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 pollution pressure
- composite priority score
