Top-Quality Perth Water Filters Help Keep Homes and Buildings Green

Many so-called “green” buildings pale in comparison to The Green Skills Training Centre in East Perth.

Western Australia’s flagship in the green campaign cost around $17 million to build and was constructed with sustainable materials. The edifice gets a full six stars from the Green Building Council of Australia, which requires structures to be sustainable and serve as role models for future projects in their communities.

One of the definitive features of the Green Skills Centre is its rainwater retention capability, thanks to its two subterranean rainwater tanks that have a combined capacity of 150,000 litres. The building also has separate tanks for black water, one 11,000-litre tank for collection, and two tanks with a combined capacity of 38,000 litres for storage.

With its ability to store vast amounts of rainwater, the building is truly designed to operate independently of water mains. This means potential savings for a city with an already strained water infrastructure. According to a recent report by the Economic Regulation Authority, nearly half of Perth’s drinking water in 2014 came from underground sources. Only 3.2 percent came from recycling solutions.

Groundwater supply is not limitless; wells dry up with increasing usage and demand. A water shortage can also have serious environmental consequences, such as the risk of ground collapse and the reduction of water in above-ground sources. Such a crisis can also threaten the local ecosystem.

Perth residents must, therefore, learn to tap into sustainable and environmentally sound sources of water. Take rainwater, for instance. A tank for every home, complete with a Perth water filtration system, can provide an entire family with enough water, even when restrictions on its use are in effect. Such a household won’t have to rely on rainwater entirely, although it may allocate rainwater for certain uses to reduce the water bill.

Companies like Rainfill Tanks and Curved Roofing Supplies not only have a large range of water tanks for many different applications they offer several types of water filtration systems. The most basic system is the first-flush filter, which operates on the principle that the first 5 to 10 litres of rainwater carry most of the pollutants. A perpendicular, vertical tube diverts the first flow until it’s full, allowing the rest of the cleaner flow to reach the tank.

To make rainwater potable, water filters in Perth rainwater tanks need to destroy bacteria in the runoff. This is a job for ultraviolet (UV) treatment (used in conjunction with the filter system), which exposes the water to UV light and targets the bacteria’s DNA. Prolonged UV exposure leads to mutations that eventually kill the bacteria. On top of that, UV treatment does not require chemicals, which can affect the water’s taste.
