This flushing program ensures that any accumulated particles in the mains are cleared out. Flushing is also performed in the fall. During spring, summer and fall, major and minor system maintenance and improvements work is performed. Such things as winter damage, replacement of old hydrants, looping of dead-end mains, new services and mains keep staff busy. Regular service calls are also made as the need arises.
System flows and pressures have to be checked and tested.
Inadequate flows and pressure can indicate problems which otherwise would not be detected. Distribution operators also draw water samples at various points in the distribution system. These samples are tested, at each location for chlorine, ensuring that the required chlorine residual is in fact present.
