Nanjikkottai

Part of Thanjavur block, Thanjavur district, in the Cauvery Delta sub-basin. Reviewed by a person on 2026-07-25.

Watch

Extensive tap-water service sits alongside severe groundwater pressure.

JJM displays tap connections for 9,512 households, with supply records spanning deep tubewells and lake sources. At the same time, the containing Nanjikottai firka is classified Over Exploited, with groundwater extraction assessed at 122.4 percent. The public record establishes the scale of service and groundwater pressure, but not whether supply is continuous, seasonally reliable, or environmentally safe.

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

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.

critical
taluk categorytaluk projection

Thanjavur 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.

Thanjavur
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. 8 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.

8 water bodies cover 19.8 ha here, the largest of them 7.4 ha. The register names 6 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.

Water-quality testing

716 samples between 2022-12-21 and 2026-08-19. 672 were taken at a source and 44 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.

Population and settlements

TNRD's Census 2011 table records 32,689 people for Nanjikottai, while JJM displays a service population of 35,135; the different vintages and programme definitions do not support a growth calculation.

drinking water

Drinking-water service

JJM displays 9,512 households and connections across 24 habitations, 30 deep-tubewell and 39 lake source rows, and 714 sample rows with a latest displayed Safe sample dated 2026-07-18.

drinking water

Public works evidence

Bhuvan lists 333 accepted geotags, including 152 water-adjacent programme records. The counts do not establish that every record is a separate asset, or that each asset is functional and currently maintained.

groundwater

Groundwater pressure

Nanjikottai firka is Over Exploited at 122.4 percent in the 2024 groundwater assessment.

What is missing

13 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 (15)

These may not be meaningful for an inland rural Panchayat. Until that is decided, they are neither claimed nor dismissed.

  • surface water change
  • river water quality
  • 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
  • crop water demand
  • agricultural water stress observation
  • agricultural water pollution pressure
  • composite priority score

What would sharpen this

  • What are the current crop area, irrigation sources, and agricultural water demand?
  • How many of the recorded lake sources and public works are distinct and functional?
  • What do current water-quality measurements show in local lakes, drains, and supply sources?
  • Where is the current Panchayat boundary in relation to Thanjavur Corporation?
