Are you experiencing problems in water supply pressure pipe networks with the following issues? 1) Pipe burst due to pressure surge. 2) Un-balanced water distribution. 3) Negative pressures in pipes causing pipe damage (flattening of pipes) or unwanted air in pipes. 4) Over utilizing of boreholes, resulting in reduced capacity. 5) Short pump life time due to cavitation of impellers and worn out bearings. I can assist you to find design solutions for the above. I have 29 years experience in the civil consulting industry, specializing in water supply design.
