Fig. 4 Longitudinal section through water tank, regulation shaft and weir span “F” For standard project cases the water for regulation purposes will be taken from the reservoir directly. For the Gomti Project the Irrigation Department has decided to maintain a separate water tank which will be feed by external water from a water pipeline. The volume of the regulation tank was selected with 2,630 m³, which amounts to 60 % of the fill volume (app. 4,000 m³) of all the rubber bodies. This covers the regulation process for almost the whole normal operation of the system. The general arrangement for the regulation system is consisting of:  Water Tank with a reservoir volume for 2,630 m³ water  Regulation Shafts with regulation equipment such as pipes, pumps, valves and safety devices  Control Building on top of the shaft building at flood safe elevation - with the electric control equipment for the whole rubber dam system including navigation locks.
