Abstract

This project provides an improved understanding of the implementation and operation of in-line turbine (ILT) generators on closed, pressure controlled water supply systems. The project documented the installation and operation of the ILT generators, and investigated pressure and flow transients and their impacts. It also investigated the effects on downstream water quality from significant and rapid fluctuations of pressure and flow that result from both normal and upset operating conditions of an ILT. Through an improved understanding of operational characteristics and modes of upset and failure, risk mitigation and control strategies and solutions can be developed that will allow more widespread application of this technology to closed, pressure controlled water supply systems. This, in turn will allow greater amounts of renewable, clean energy generation by water utilities. Tailored collaboration partner: Halifax Water. Published in 2016.
