ABOUT Water Supply

Drinking water supply to the city was developed as early during 1891 with Hussainsagar as Source. Water from Hussainsagar was drawn to Filters at Narayanguda and re-transported to Residency (Koti).In 1898 Miralam Tank was brought into use duly treating at Miralam Filters and supplied to low lying areas of South of Musi (Old City). Jeedimetla Tank was the source of supply to Secunderabad area.River Musi received floods during 1908. The flood waters entered the city and inundated many areas resulting in loss of life and property. This necessitated flood control measures and Sri.M.Visweshwaraiah suggested for construction of two storage reservoirs on Musi as Osmansagar and on Esi as Himayatsagar.As the population of the then Hyderabad started increasing, the said flood control storage reservoirs were converted as drinking water supply sources and supply began from Osmansagar in 1920 (construction began in 1912 and completed in 1920) and from Himyatsagar in 1927 by gravity.As the demand was ever growing for filtered water for drinking purpose, Manjira Barrage was constructed in 1965 to provide 15 Mgd water to the city under Manjira Phase-I.Later, Manjira Water Supply Scheme Phase-II was taken up during the year 1981 to bring another 30 Mgd water into the system.The Hyderabad Metropolitan Water Supply and Sewerage Board (HMWSSB) was enacted through HMWSS Act 1989 (15 of 1989) and is a statutory authority in charge of providing and maintaining water supply and sewerage facilities to Hyderabad City from 1.11.1989.As the urbanization of Hyderabad was on rise, the demand for drinking water supply kept on increasing resulted in tapping water from Singur Dam as Manjira Phase-III in 1991 with Govt. funds to augment additional 30 Mgd of water.Manjira Phase-IV from Singur Dam was taken up in the year 1993 with World Bank Aid to bring additional quantity of 30 Mgd of water.

With the above water supply augmentations from Osmansagar, Himayatsagar, Manjira and Singur, a quantity of 145 Mgd was drawn till the year 1998. In 1998, A Project known as “Refurbishment of Water Supply” was taken up for full drawal of 6.96 TMC of allocated water from Singur & Manjira, and an additional quantity of 17 Mgd was brought into the system. Thus the supplies totaled to 162 Mgd.

Krishna Water Supply Augmentation:

Consequent to the continuous failure of Monsoons, Osmansagar, Himayatsagar, Singur and Manjira have not being receiving adequate inflows, resulting in less storage in Singur and Manjira and drying up of Himayatsagar & Osmansagar. In the last 20 years Osmansagar got filled up to its full capacity only for 8 years and Himayatsagar for 10 years, thereby the dependability of the sources has come down below 50%. As the demand for water was ever growing not only in MCH area and in surrounding Municipalities, further augmentation was necessitated in bringing Krishna water.The Krishna Drinking Water Supply Project Phase-I with two stage of implementation was taken up during Nov’2002.The Krishna Drinking Water Supply Project Phase-I with an out lay of Rs.820 Crores was commissioned in full in April’2005 for a drawal of 90 Mgd. The project envisaged 90 Mgd of WTP in 2 stages (45Mgd+45Mgd), 6 Clear Water Reservoirs at 5 locations of total 90 ML, Pumping stations with pumping plants & substations at 3 locations, 2200 mm dia MS Pumping / Gravity Pipeline for a length of 116 Kms.With the advent of 90 Mgd of Krishna Drinking Water Supply Project Phase-I, it was thought that the city could have sufficient water to meet the gap between Demand and Supply. The existing sources since have not been receiving inflows in the previous years and the water storage reached to its lowest ebb during summer 2005. Himayatsagar totally dried up in Dec’2004 and Osmansagar totally dried up in June’2005. Singur Reservoir water level got depleted to 1 TMC in June’2005. In order to meet the above contingency situation in future, HMWSSB proposed to the Govt. to take up the Krishna Drinking Water Supply Project Phase-II, for additional drawal of 90 Mgd from river Krishna.The KDWSP Ph-II is completed in all respects to draw additional 90 Mgd of water to Hyderabad Urban Agglomeration (HUA). By commissioning of KDWSP Phase-II, the total installed capacity was reached to 340 Mgd and fed to GHMC and peripheral areas.

Godavari Water Supply

With the constitution of Greater Hyderabad, and with many growth triggering initiatives being taken up in the City, City is attracting lot of investment from National & international agencies. As a result economic activity is going up thereby attracting lot of immigration from various parts of State as well as the Country. Keeping in view all these, GoAP decided to work on the water source augmentation from River Godavari. The Detailed Project Report for Godavari Drinking Water Supply Scheme Phase-I was prepared by M/s WAPCOS. As per the DPR, the Godavari Drinking Water Supply Scheme Phase-I envisaged for a drawal 10 TMC with Yellampally Barrage as source. The project is taken up, completed and commissioned in 2015.

Krishna Phase-III:

In order to bridge the gap between supply and growing immediate demands of the Hyderabad Urban Agglomeration, a decision is taken by the Government to go for the Krishna Phase-III for augmenting another 90 Mgd from river Krishna through existing source at Akkampally Balancing Reservoir. Accordingly the KDWSP Phase-III project is taken up and completed for 90 Mgd capacity (5.5 TMC) and commissioned in 2015.

With all the above sources of Manjira Phase-I, II, Singur (Manjira Ph-III & IV), Krishna Phase-I, II, III and Godavari Phase-I, the total installed capacity for Hyderabad Drinking Water Supply is 602 Mgd. At present a quantity of 430 Mgd is being supplied in the service area of HMWSSB which is extended beyond GHMC limits upto ORR.

Presently, HMWSSB is drawing water from the following sources whose normal drawls and present drawls are below.
