Why is the water from Bowmanston Pumping Station muddy after heavy rains?
The problem is due to sucks or fissures connected to the cave feeding Bowmanston well. No filtration is provided to the muddy runoff going into the sucks. This only occurs with high intensity rainfalls.
What is involved in leak detection?
The following activities are involved in leak detection:
- Isolating a given water main, checking how much water is going through it and comparing this with the amount required to service the users connected to it.
- Locating the position of the leak by using sounding equipment (listening for sound of escaping water during the daytime) or noise correlators.
Is age the main cause of burst pipes?
No, age is not the main cause of burst mains but it is a major factor. Some bursts are due to increased traffic load since most of the pipes are laid in the road. Bursts may also occur due to corrosive environment that attacks the pipe.
How is BWA addressing ongoing water issues?
The BWA has put a number of measures in place and these include:
- Replacement of stopped meters.
- A comprehensive water conservation program
- Intensified leak detection and mains replacement programmes
- Modifications to the distribution system to increase water transfer capabilities
- Investigations for locating and excavating wells to optimise groundwater extractions
- Review of options to supplement the groundwater sources (i.e. use of runoff, treated waste-water and desalination)
- Public education program development
