What is rainwater harvesting

Rainwater harvesting involves the collection, filtration, storage, and distribution of rainwater from the roof, for use inside and outside the home or business.

How can rainwater be used

Before the advent of mains supply, rainwater was a major supply of water for both human and animal use.. Rainwater has been used for generations as the only source of water for all requirements, including drinking water, and this is still the case in many countries, including Ireland, tody.

Today, even when mains water supplies are available to communities,many people choose to use rainwater that is collected from the roof and stored in tanks or to supply their water requirements. Rainwater is an ideal source for our water requirements and momentum behind rain harvesting is building.

Rain Harvesting is a great GREEN initiative. It reduces dependence on mains water supplies.

Rainwater is a sustainable water supply

Rainwater that is captured and stored correctly is a sustainable source of quality water. Safety measures can be applied to the manner in which rainwater is captured, stored and dispensed. In fact some people argue that rainwater is safer than water supplied through mains. Our mains water is typically stored in reservoirs, treated with chemicals such as chlorine to kill of bacteria and make it safe, and then pumped through a network of pipes throughout the community. It makes sense to use rainwater that falls for free without chemicals.

Significant economic, social and environmental benefits can be achieved by using rainwater.

By using Rainwater Harvesting systems to supply water for some, or indeed all of our requirements, you can reduce your dependence on mains water. Our water supplies are falling and water restrictions are often in place in many counties to reduce our overall water usage and protect our supplies.

Rainwater falls for free - once you have installed a rain harvesting system, you use less mains water and can reduce your water bills. Governments and Water Boards will increase water prices as they look to recover the true costs of providing water to the community.

The cost to the community to supply mains water services is collosal. The construction of dams, pipes and watertreatment works is huge and ultimately as tax and rate-payers, we foot the bill.

Rainwater Harvesting reduces the significant damage to rivers and wildlife caused by stormwwater runoff, flooding and drought.

The Government have introduced new regulations and water efficiency ratings that must be incorporated into new dwellings.
