The design of a pumping station involves many aspects of civil and mechanical engineering, the hydraulic design forming only part of the whole process. The hydraulic design deals with the channelling of liquids into the pump, the flow through it and the discharge system. An unsatisfactory hydraulic design of the intakes and sumps could have far-reaching implications on the overall performance of the pumping station. This publication discusses the flow and control of water from its entry into the pumping station up to its entry into the pump. The issues involved in deciding the hydraulic easing of a pump sump and intake are outlined in the guide. It recommends good design practice for a variety of pumping situations and preferred designs. The circumstances in which hydraulic model tests are desirable are defined and guidance is given on the conduct of such tests.
