Rainwater Capture is an environmentally friendly way of reducing the impact on the local watershed while at the same time lowering monthly water bills. Using rainwater has many benefits including its total lack of chlorides, its fewer salts and its zero hardness. The three components of rainwater systems include the capture system, the storage system and the delivery system. Depending on the nature of the system you choose rainwater capture systems can be used solely for the garden or for domestic household purposes.
