Design & Engineering
Thokarwadi dam situated about 45 km from Pune forms storage reservoir for Bhivpuri Hydropower Station. The dam was constructed across Andhra river near village Thokarwadi during the years 1917 and was completed in June 1922. It is a gravity structure having a hearting of lime concrete between upstream and downstream face walls of rubble masonry. The dam is nearly 60m high and 741 m long has a gross storage capacity of 410 Mm3
When constructed, the dam was not designed for earthquake forces and uplift pressures. In view of the recent seismic activity in this region, the dam has been strengthened to cater to earthquake forces as well as uplift pressures. Strengthening has been carried out by construction of buttresses in colgrout masonry at the downstream face of this dam. The buttresses 8 in number are 15 m thick and 28 m wide. The buttresses have been designed for raised FRL of the dam by another 0.3 m.
