    Abstract：With the integrated construction of drainage project，electrical facilities for water utilities are more diversified，which puts forward higher standards for electrical design in drainage engineering. Through analysis of common problems in design，streamlining the electrical mandatory provisions. By means of examples of design，analyzing the power load classification and selection of transformer operation mode for sewage facilities of different scales，as well as the common schemes，principles and cautions for drawing review of quantities and locations of substations and distribution rooms in the wastewater treatment plant，to provide reference for the technical personnel engaged in electrical design of relevant fields.
