Rainwater Harvesting

With climate change now a reality rather than a speculated possibility, the demand on water resources has gone up, whilst the amount of water available for supply has gone down. Forth coming regulatory changes will mean that over 90% of UK homes will have their water usage metered, making consumers more and more aware of how expensive the commodity of “common or garden” water has become.

From a simple, above ground water butt to below ground storage tanks and comprehensive, automatic recycling systems, AA Biotech”s range of rainwater harvesting products provide versatile, economic and ecological solutions and give consumers the ability to freely collect water and use it with out feeling guilty; on their plants and lawns, for washing their cars, in their washing machines and in their toilets.

There are so many Benefits of using rainwater, firstly rainwater is a huge money saver because it falls free from the sky and you can save as much as you like, using it how you want. Rainwater is an environmentally friendly natural resource which is easy to maintain

Rainwater harvesting systems can be simple to construct from inexpensive local materials, and are potentially successful in most habitable locations. Roof rainwater can be of good quality and may not require treatment before consumption. Although some rooftop materials may produce rainwater that is harmful to human health, it can be useful in flushing toilets, washing clothes, watering the garden and washing cars; these uses alone halve the amount of water used by a typical home. Household rainfall catchment systems are appropriate in areas with an average rainfall greater than 200 mm (7.9 in) per year, and no other accessible water sources.

There are a number of types of systems to harvest rainwater ranging from very simple to the complex industrial systems. The rate at which water can be collected from either system is dependent on the plan area of the system, its efficiency, and the intensity of rainfall (i.e annual precipitation (mm per annum) x square meter of catchment area = litres per annum yield) … a 200 square meter roof catchment catching 1,000mm PA yields 200 kLPA.
