Drinking water supply, rainwater tanks

When building a new house or renovating an old house we have a chance of economical use of drinking water which is usually obtained from a distribution system. Using rainwater in and around your home is an easy and effective way to conserve drinking water:

• flushing toilet
• dishwasher and washing machine
• watering the garden, flowers
• car wash ..

Rainwater in rainwater tank shouldn’t require treatment or disinfection if it is not being used for
drinking and food preparation.Using rainwater reduces the water bill and bring additional costs to build a system for rainwater use. (fixtures, tank, pipes and pumps to ensure that rainwater remains separate from the mains drinking water supply,)
If a mains drinking water supply is available it is not recommended that you use
rainwater for drinking and food preparation. The quality of water in household
rainwater tanks is generally not as reliable as mains supplies, which have been
treated to a level to ensure they are safe for human consumption.
