Perth has many sources of water collections for mains potable water for use throughout housing and industry.
- Desalination plant 27%
- Surface Water (rain water) 33%
- Ground water 40%
Ground water is the highest source of water used in Perth’s water mains, ground water is heavy in sediment and calcium.
Sediment and Rust
The majority of Perth’s mains water pipes are over 80 years old and made of steel, this introduces rust into our drinking water. Rust and sediments are the two major problems with hot water units and fixture failures within the family home. The build-up of sediment reduces the heating performance within storage hot water units as the sediment settles at the bottom of the tank, along with blocking plumbing fixtures such as cistern inlet valves, dishwasher, washing machine and garden reticulation valves.
To combat the aging pipes the Water Cooperation has introduced large amounts of chlorine over the years to reduce bacteria and the taste and odour of the sediment and rust within the water mains.
Calcium
Calcium is the biggest cause of hot water unit failure and dishwasher problems. Calcium build up reduces performance and or break fixtures and fixture units down. Calcium accumulatations can most commonly be seen in shower areas, shower heads, on tiles and glass screens.
Heavy sediment, rust and calcium in the water can lead to failure of plumbing fixtures and burst water pipes within the family home. Burst water pipes can cause serious damage to the home and generate high costs to the homeowner for repairs and replacement of damaged property.
- Thinning of pipe wall thickness leading to water pipe bursts
- Blocking of internal water piping (build-up of calcium)
- Reduction in water heating performance due to scale build up from calcium
- Reduction in water heating performance due to sediment and rust in water
- Failure of internal solenoid valves of washing machines and dishwashers
- Failure and blocking of taps and flick mixers
