Gram Panchayat|LGD 228906Water profile
Thoppuviduthi
Part of Thiruvonam block, Thanjavur district, in the Cauvery Delta sub-basin.
Every household has a tap; the source is not characterised
All 701 households report a tap connection, but no groundwater assessment covers this place, so the security of what those taps draw on is unestablished.
701 of 701 households, across 14 habitations.
Deep Tubewell
30 rain days between 2026-08-01 and 2026-08-31, modelled rather than gauged.
Safe on 2026-07-28. 132 samples over 4 years, none of them recorded unsafe.

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 |
Tanks and water bodies
Mapped by TNGIS and assigned to this Panchayat by the register itself, not by a name match.
11 water bodies cover 19.1 ha here, the largest of them 8.2 ha. The register names 10 of them; the names and polygons are withheld pending the TNGIS licence reply.
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 |
|---|---|
| NRSC | 6 |
| WRD | 3 |
| AED | 1 |
| TNRD | 1 |
Water-quality testing
132 samples between 2023-01-02 and 2026-07-28. 91 were taken at a source and 41 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 |
|---|---|
| 2023 | 47 |
| 2024 | 29 |
| 2025 | 32 |
| 2026 | 24 |
Land and irrigation
Census 2011, reference year 2009. A historical baseline, not current cropping.
of 686.9 ha total.
canal 202.05 ha, wells 157.78 ha, tanks 0 ha.
culturable waste; barren 0 ha, forest 0 ha.
Sources through the summer
Census 2011, reference year 2009.
2 source types were recorded for the year and 2 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
14 of 40 capabilities are supported by acquired evidence. The rest are named here rather than left blank.
