Waterhammer Protection for the Toshka Pumping System
Publication: Building Partnerships
Abstract
The Southern Valley Development Project (Toshka) is a major project located 1,000 km south of Cairo, Egypt. The project involves pouring Nile water out off Lake Naser into the desert in order to reclaim parts of it for agricultural use. The Toshka project is considered one of the largest projects in the world with its unique pumping station that delivers 25 x 106 m3/day (~300 m3/sec). As a result, safety is a major concern and maximum protection measures against waterhammer should be incorporated into the project's design. Waterhammer analysis will provide the required protection that is needed for both pump and pipeline. This paper contains numerical model that simulates pump power failure followed by a valve closure for a pumping system drawing liquid through a single pipeline and discharging it into a reservoir. The method of characteristics was used to solve the transient pressures in a liquid-filled piping system.
