Water Resources Assessment for Hubli Dharwad, Karnataka India.

This research was was conducted in April 2001 as part of the NRSP livelihoods and the peri urban interface project. The relevant departments dealing with water and sewage were interviewed, visits were made to surrounding villages and the water quality surveyed. The water quality analysis was done by S.G.Joshi.

Since 1956 Hubli-Dharwad has relied on piped reservoir sources, while the rural areas have increasingly relied on boreholes. Increasing amounts of water are now being abstracted for irrigation in rural areas and many boreholes are now dry or have hard mineral waters which are bad for human health and damages some crops.

In the Hubli – Dharwad urban area in 2001:-

  • 40% of the water supplied by the water supply network leaked into the ground
  • There were no sewage treatment facilities
    • 30% of sewage went to cesspits and then seeps into the ground
    • 70% of sewage entered the sewerage network where it leaked into the ground or drains eventually to local rivers, which is used for irrigation in rural areas

The main conclusion of this study was that leakage from the water mains and sewers under Hubli Dharwad were recharging diluting the over exploited and saline groundwaters. As a result villages relying on boreholes nearer the urban areas had access to less saline waters.
