There are two reservoirs namely Osman Sagar and Himayat Sagar formed by the above rivers respectively. The drainage system in the area is semi-dendric to rectangular type indicating poor permeability in character of the soil. 4.1. RAINFALL: The annual rainfall data from 1901 to 1996 is collected for the study (see Appendix). The study of the data indicates that about 74 percent of the rainfall is received during the southwest monsoon and the northeast monsoon’s contribution is only 14 percent. The distribution of annual rainfall is given below,

4.3. HISTORY OF WATER SUPPLY FOR HYDERABAD CITY: Human tendency is to act only when there is a catastrophe. On September 28, 1908, the city of Hyderabad was over whelmed by an unprecedented deluge caused by the river Musi. Most of the city was submerged. There was great loss of human lives and property. In order to prevent a recurrence of the same disaster, two dams were constructed across the Musi and its tributary Esi (Musa), on the advice of Sir. M. Visweswaraya, the celebrated engineer-statesman, in 1922 and 1927 respectively forming the Osman Sagar and Himayat Sagar reservoirs. These are the principle sources of water supply to the twin cities. The Umda Sagar near Falaknuma and the Mir Alam tank had been the main sources of drinking water south of the Musi River, before the Osman Sagar and the Himayat Sagar water supply were commissioned. The Hussain Sagar Lake built in the 16th century provided water to some localities north of the Musi River, while Secunderabad received its supply from the Faukl Sagar at Jeedimetla. All these sources became insignificant after the development of the Osman Sagar and Himayat Sagar, and were abandoned. Hussain Sagar, which lies in the heart of the city, is heavily polluted and is now only used for boating and regatta. After the formation of the Andhra Pradesh state in 1956, there was a sudden influx of population and a spur in the growth of new industries. Consequently there was a greater demand for water supply, and hence a need for execution of new projects.
1923 New Hyderabad water supply scheme commissioned 1932 Remodeling of Hyderabad water works, 122.74 MLD 1965 Manjira Water Supply Scheme, Phase - I 1981 Manjira Water Supply Scheme, Phase - II 1991 Manjira Water Supply Scheme, Phase - III 1994 Manjira Water Supply Scheme, Phase – IV 4.4. PRESENT WATER SUPPLY SITUATION :
Hyderabad Metropolitan Water Supply And Sewerage Board (HMWSSB): The Hyderabad Metropolitan Water Supply Sewerage Board (HMWSSB) is a statutory authority in charge of providing and maintaining water supply and sewerage facilities within MCH limits covering Hyderabad and Secunderabad cities. The HMWSSB also supplies bulk quantities of water in the nine adjoining municipalities, Osmania University Campus and Secunderabad Cantonment and enroute villages along National Highway No.9 up to Sanga Reddy. The HMWSSB’s activity in maintenance of water supply and sewerage system since its constitution in 1989 was confined to the Municipal Corporation of Hyderabad (MCH) area 172.6 sq. km. During the year 1995 the HMWSSB has resolved to take over the maintenance of water supply system of 9 municipalities adjoining Hyderabad. Accordingly, the government of Andhra Pradesh directed the municipalities in March 1996 to hand over the water supply and sewerage operations to HMWSSB. So far water supply of only 3 municipalities – L.B.Nagar, Kukatpally and Qutbullapur have been taken over by the board. 4.5. SOURCES OF WATER: At present, water is being supplied to Hyderabad city from four impoundment on three rivers.

Out of 333 are private tankers of capacity 5KL, and 11 HMWSSB tankers of capacity 10KL. The slum areas and new colonies which doesn’t have water supply pipeline, are supplied by the tankers. Each generate 8 trips per day. 4.6.WATER SUPPLY DISTRIBUTION IN MCH AREA: HMWSSB divided MCH area into seven division. And further the seven division are divided into 20 sub-divisions/zones. Details of water supply distribution in mch area as follows. 4.7. PROJECT FROM LAST 8YEARS (1995-2003):
