Rainwater Harvesting treatment process

Rainwater is not just the start of the water cycle, it is our most valuable water source. Rainwater sustains the life for every living thing, and it must be protected in this age of climate variability and environmental challenge.

Our Sparkle | Water | Quality philosophy is that there is only one water, and we should treat it naturally. We do this by harvesting natural rainfall as either rainwater or stormwater and keeping it in the best possible condition for utilisation, storage, or environmental discharge.

The collection and storage of rainwater as a suplimentary water source is becoming increasingly important as the world's population becomes more urbanised and water shortages become more frequent. An urbanised population also places increasing pressure on the water delivery infrastructure that delivers piped water from rivers and dams that can be hundreds of kilometres away.

Rainwater harvesting can ease this burden by utilising local rainwater for garden irrigation, car washing, toilet flushing, and laundry use etc.

Supplimenting the piped water supply with harvested rainwater can save up to 65% of the fresh water delivered to a domestic property and provide useful savings in the cost of the water, and the energy required to bring it from a far distant dam.

However, rainwater harvesting does require proper planning and implimentation to ensure that the maximum benefit is obtained from the harvested water. Issues such as roof catchment contamination and storage quality play a major role in an efficient harvesting system.

When rain falls on a roof it will wash off the pollutants that have collected since the previous rain event. This contaminated water includes pollutants such as dust, leaves, and bird droppings which should all be prevented from entering the storage system.

A 'First Flush' diverter will separate the heavily contaminated first flow of water from a rain event and direct it to the waste drain. The subsequent higher quality water is then directed to the storage tank, usually via a fine filter.

Our rainwater management systems are designed to deal with these contaminant and ensure that the water placed into storage for later use is in the best condition possible.
