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.

JJM records service for each habitation separately. A Panchayat total can hide a habitation that is behind.

| Source | Category | Count |
|---|---|---|
| Shallow Tubewell | Ground Water | 10 |
| Deep Tubewell | Ground Water | 3 |
| Infiltration well | Ground Water | 2 |
| Non Conventional Methods (Tribal/Others) | Others | 1 |

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.
Mannachanallur 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. 1 TNRD blocks span more than one revenue taluk, so a block-to-taluk name match would have been wrong.
Water-quality testing
141 samples between 2022-10-29 and 2026-08-20. 73 were taken at a source and 68 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.

12 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
- historical water access
- 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.

- river water quality
- engineered stormwater drainage
- wastewater treatment assets
- pollution pressure inventory
- measured water pollution
- coastal and estuarine
