What is the solution where water is supplied by one pump to more than one building?

In this case, Watchman will be installed with in-built hooter system in each and every building which will show the level of water of overhead tank either the tank is empty or full, by sounding hooter with lighting signal. And the manual operator will operate the valve of pump accordingly. Alternatively it can be installed for more than one building where the pump will start when any one of the overhead tank is empty, and the pump will stop when all the overhead tanks are full of water.
