No site has sent a reading in the last 24 hours, so the condition right now is not known. The latest reading came in 43 days ago (22 Sep 2026, 19:39 IST).
Last known, not current. The last problem found at each of the 12 water bodies, in readings from 4 Jun 2026 to 21 Sep 2026:
- 7 over the limit
- 5 warning

Simulated readings. 12 rivers, creeks and coastal waters in the Mumbai, Konkan, Nashik and Pune areas, by region. Open a region, then choose a water body to see each monitoring site and its readings. Times are Indian Standard Time (IST).

What the condition words mean
- Within the limit
- No reading over the limit in the last 7 days. It does not mean the water is safe to drink.
- Warning
- An unusual reading worth a look, close to the limit but not over it.
- Over the limit
- A reading over the limit. A sensor reading is a first check, not legal proof.
- Well over the limit
- A reading well over the limit.
- No current reading
- The site has not sent a reading in the last 6 hours, so we show no condition. The last problem found is listed with its date.
The limit is the Central Pollution Control Board (CPCB) standard that applies at that kind of place. Which limit applies.
Values are in milligrams per litre (mg/L); conductivity in microsiemens per centimetre (µS/cm); turbidity in nephelometric turbidity units (NTU); temperature in degrees Celsius (°C).
Your river not here? This pilot checks 12 water bodies in the Mumbai, Konkan, Nashik and Pune areas. SaveNadi does not monitor others yet. For official information, visit the Maharashtra Pollution Control Board (MPCB) website.
How it works
From a sensor in the water to an officer's decision, in four steps.
Sensors check the water
Sensor boxes in rivers, creeks and the sea are designed to check the water every 30 seconds. In this pilot the readings are simulated.
Each reading is checked against the limit
Every reading is compared with the Central Pollution Control Board (CPCB) limit for that kind of place.
An officer is alerted
When a limit is crossed, a case opens for a Maharashtra Pollution Control Board (MPCB) officer to review. AI (artificial intelligence) suggests where to look first. In this pilot the cases are tests and no officer acts on them.
Act, and keep watching
An officer always decides what to do. The sensors then show whether the water gets better, and everyone can see the water quality on this website.
About SaveNadi
SaveNadi is a pilot run by Aegis Knowledge Trust for evaluation by the Maharashtra Pollution Control Board (MPCB). It is not an official Government of Maharashtra service.
The pilot is set up for 23 places: 11 where industrial areas release waste water, 9 on rivers and 3 on the coast. It is designed to measure 12 things in the water.
Polluted water harms people's health, fish, farms and the livelihoods that depend on rivers.
Can you trust these readings?
Readings are simulated in this pilot
A computer makes them to test the system, and every record says so. They are not for enforcement. About this pilot
A sensor reading is a first check, not legal proof
Legal action needs a water sample taken in the proper way and tested in a government-approved laboratory. Why a sample is needed
AI (artificial intelligence) only suggests where to look
When a limit is crossed, it suggests which registered factory's waste is most like what the sensor found, so an officer knows where to look first. It does not prove who is at fault. How the suggestion works
An officer decides
SaveNadi is built so that a Maharashtra Pollution Control Board (MPCB) officer checks each case and decides what to do. No company is named on this website unless an officer has published a finding.
Published findings
None. If MPCB adopts SaveNadi, a finding confirmed by an officer, with its order reference, would appear here.
Check a record
Every record of a problem has a reference number, such as SNE-2026-000772. You can check that a record has not been changed since it was made.

What the proposal asks
Link SaveNadi to the online meters that highly polluting factories must already have, and check the meters' readings against readings from sensors that SaveNadi would place in the rivers.
Under Central Pollution Control Board (CPCB) directions of 5 February 2014, 17 categories of highly polluting industries, and the shared plants that treat factory waste water (common effluent treatment plants), must fit these meters, called the Online Continuous Effluent Monitoring System (OCEMS), and send the data to the Maharashtra Pollution Control Board (MPCB) and CPCB.
