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 | 29 |
| Shallow Tubewell | Ground Water | 4 |
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.
Ponneri 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. 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.
2 water bodies cover 45.1 ha here, the largest of them 37.2 ha. The register names 2 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.
| Registered by | Water bodies |
|---|---|
| TNRD | 1 |
| WRD | 1 |
Water-quality testing

Land and irrigation
Census 2011, reference year 2009. A historical baseline, not current cropping.
of 1,192.59 ha total.
canal 0 ha, wells 374.37 ha, tanks 96.04 ha.
culturable waste; barren 0 ha, forest 0 ha.
Sources through the summer
Census 2011, reference year 2009.
3 source types were recorded for the year and 3 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.
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
- 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
