Rainwater Harvesting: the How-to Guide
Save water this summer with these simple solutions from Marley
Rainwater harvesting is becoming an increasingly hot topic. It is one way you can improve the economy of water usage in your family home.
In New Zealand, a good household rainwater harvesting system can reduce the reliance on your standard water supply by between 25% and 40%. Harvested water is diverted to areas of the home like the laundry, toilet, or even the garden for irrigation. The average New Zealand household uses an estimated 20% of its annual water consumption just to flush the toilet! Using harvested rainwater instead of standard water supply makes fantastic environmental (and financial) sense.
Putting together a rainwater harvesting system does not have to be a daunting task. In fact, it’s possible to fit one in just a couple of hours, with a complete, easy-to-install system available from Marley.
How it works
The system is designed to collect water off the roof and divert it through a filter and first flush diverter to remove the majority of contaminants. The clean water is then collected in a storage tank. From there it can be distributed through a pump to the areas suitable for use of harvested rainwater.
According to Marley, when collecting rainwater as a partial or total source for a water supply, it is essential the design of the system meets the need for potable (safe drinking) water.
Water collected from a roof and stored and distributed from a water tank can contain a nasty range of pollutants that can contaminate your water, such as bacteria from bird droppings, insects, rotting debris, airborne dusts or pollution that can gather on your roof.
A cost-effective solution
The Marley Rain Harvesting System comprises a number of unique and cost-effective components that are designed to help make tank water as clean as possible. However, Marley advises having your tank water analysed to check its potability.
Fitting a rainwater harvesting system is more than just a ‘feel good’ process; it’s a really effective way of ensuring you’re using our planet’s resources effectively and efficiently while reducing water wastage…and that’s got to be good for everyone.
