This revised edition of the Water Pumping Station Operations and Maintenance Manual replaces the former document titled: Operations and Maintenance Manual – Water Pumping Stations (January 2003). The user of this manual will be those local government authorities (local water utilities, or LWUs) throughout NSW responsible for the operation and maintenance of water pumping stations. This manual is designed to provide information to assist each LWU to prepare their own O&M Manuals.
