1.Belagavi city has 58 wards and a total of 59684 water connections
2.the city gets its drinking water supply from Rakaskoppa and Hidkal which are 18kms and 52 kms from Belgaum respectively.
3.a total of 6714 HP pumps are used to deliver this water to the people of Belgaum.
4.Electricity cost of approx 13.28 crores is incurred to run these pumps.
5.600 workers work round the clock to ensure drinking water supply from source to the consumer
6.Total cost of rs 7.27 crores approx is incurred to meet the salary requirement of the 600 workers.
7.There are a total of 363 hand pumps, 403 power pumps, 632 general taps and 57 dug wells in the city.
Rakkasakoppa dam was built during 1962. The capacity of damage was 0.58 Tmcft. From Rakkasakoppa dam water flows by gravity for a distance of 15KM to Hindalaga pumping station. From Hindalaga pumphouse water will be pumped for a distance of 3Km to Waterloo Treatment plant in Lakshmitek .
The scheme has been updated twice as and when required to increase drawl of water from Rakkasakoppa. Recent enhancement was done during 2008 under world Bank aided scheme. Under this scheme the drawl from Rakkasakoppa has been enhanced from 9MGD to 12MGD (Million gallons per day) by changing pipelines and pump sets. Old 400HP pumpsets were replaced with 2 Nose of 600HP Pumpsets. Scheme has been upgraded periodically based on increase in population and population of city is 492157 as per 2011 census.
Even the capacity of the Rakkasakoppa dam has been enhanced by rising the Full reservoir level by one foot by rising waste weir gate.
In addition to Rakkasakoppa scheme one more scheme was commissioned from Hidkal dam during 2000 with an installed capacity of 12 MGD out of which city gets about 8MGD. The distribution system in 10 wards of city has been converted to 24X7 benefiting about 1.00Lakh population with 24X7 water supply. The existing workforce is to bring water from both the sources to city and to distribute the same to about 5. 25Lakh people of city and also to maintain other sources of water supply from borewell s and open Wells. It also includes work force for Revenue collection. Hence all attempts are being done to adopt new technology.
The capacity of Rakkasakoppa dam has been increased periodically. When the dam was built the Full reservoir was fixed at 2470 and a surplus escape was built to allow surplus rain water to overflow to river coarse. But as population grew the Full reservoir level was increased to 2475 by fixing waste weir gates in the year 1988 and the capacity of the dam was measured as 0.58 Tmcft. Again in 2013 the gates were rised by one foot and fixed at 2476 thereby increasing capacity to 0.60 Tmcft.
National institute of Hydrology (A Govt. Of India Enterprise) took up study of capacity and siltation of Dam during the year 2000 and found that siltation is very meagre and was less than 4% that too in lowest valley portion and has not affected the live storage of the tank.
The lowest drawl level is 2446 whereas the lowest bed level of the dam is 2424. The reason for low siltation is property of catchment area which is Western ghat and water flows in Laterite zone . Only after studying these aspects the idea of desilting was dropped and FRL was raised by one foot. During 2013 the monsoon was delayed and water level in the dam reached 2446. During that period the dam was surveyed for capacity by conducting block level survey of the entire water spread area of the dam using Total station ( Electronic surveying instrument) and found that there is not much siltation of dam.
But the FRL of dam cannot be rised further as the submergence land comes in Maharastra and lead to dispute. Only after studying these aspects we have gone for alternative source and new water supply scheme was implemented from Hidkal dam which has sufficient storage capacity of 51 Tmcft. Govt. has allocated 1.75 Tmcft of water in the dam for drinking water demand of Belagavi, Hukkeri, Sankeshwara and other enroute villages. This scheme was commissioned during 2000.
