* The present drinking water sources of Bhubaneswar Municipal area includessurface sources (rivers) and ground water sources.

* These Rivers are Kuakhai, Daya, Mahanadi , which supply around 80% of thetotal daily demand of potable water,

while the balance is obtained from

groundwater sources through production

wells and tube wells.

* It is informed that around 4.5 lakh

(42% of total population) people depend

on the water supply system provided by

Public Health Engineering Department (PHED).

Water demand and supply* The present supply of water from all surface sources is around- 172 MLD* Ground water contribution of - 46 MLD* Total water supply is- 218 MLD ( anticipating 15% losses )* The per capita water availability is- 190 lpcd.* As per Manual on Water Supply and Treatment ,it recommends a water supply of

150 lpcd. Allowing for a loss of 15%, this may be rounded off to 173 lpcd.*

The total water demand of the Bhubaneswar Municipal Area considering the rate of water supply of 200 lpcd will be around 216 MLD

Supply coverage* As of now, the existing supply system fully covers 17 wards (out of 47) with

pipe-water supply* 26 wards are partially covered* 4 wards do not have piped water supply* 36% of households are presently using water connections* Many authorized and unauthorized slums exist in the area, which are fed from

hand pump tube wells or stand posts provided by BMC.*

The total length of pipelines (main and distribution) are about 911 km inlength .* Nos. of service connection- 52,300* Reservoirs

Under ground Reservoir- 87 nos. (cap.31,900 m3)

Elevated Reservoir- 46 nos. (cap 8,400 m3)

* Number of India Mark II Hand Pumps - 933* Number of public stand posts- 212

Surface sources* 80% of water demand is full filled by surface water supply* The rivers Daya and Kuakhai run along the eastern and south eastern

boundary limits of the city, providing for low-cost raw water transmission.* The Kuakhai River is classified as Class C best-designated-use as per the

Water Quality Atlas of India.* Since these rivers are not perennial , during summer the discharge remains low

and necessitating supplementation is full filled from Mahanadi (30 km northof the city)or other ground water sources.

Ground Water* It is reported that around 40% of the population are using ground water with

the average ground water level reported between 18-24 m in the production

wells.* But, many of these tube wells are thought of suffering from excess iron

concentration and low pH in ground water.* In total, around 1850 tube wells and 104 production wells are available in

the area.

Key Issue* A study carried out on the system reveals that supply is intermittent, while

pipelines have shrunk, As most of these were laid in 1950s and 1960s ,While density of population has increased, the same has rendered existing

supply lines inadequate.* This also explains why water distribution has not been uniform quantity

as well as pressure wise .* Moreover, main transmission lines are now old and lead contamination with

sewerage lines which has become a cause of concern.* The presence of contaminants like iron and coliforms in ground water are

reported increasing.* Another problem with the locations and capacities of storage reservoirs In

the city, as they are not integrated.
