According to the hydraulic characteristics of the water supply pipe network, the optimization design objective function of the water supply system is proposed, which takes the pipe segment pressure and the pipe segment flow as the variables, and the simple gradient method with obvious optimization effect is used for calculation. The objective function transformation technology is proposed by combining the penalty function method. Directly solve the problem of solving the standardization of the diameter of the pipe, and the example shows that the calculation efficiency is high and the reliability is strong.
