Saving Money

Rainwater tanks are a great way to reduce mains water consumption and save on your water bill, they are also environmentally friendly. Local homes and businesses using rainwater tanks to collect and store water also reduces the infrastructure the cost for the local area and improve storm water quality.

The water collected in a rainwater tank can be used for drinking, for which we suggest using Aquaplate as it is the best option for drinking water quality. The water can also be used for watering the garden, bathrooms and laundries or in some cases the entire house can be reliant on a rainwater tank.

Rainwater needs to be filtered if it is going to be used for drinking, we are able to suggest appropriate filters and where they should be installed to get maximum benefit.

Fire Tanks

In rural communities, it is a requirement to have a London fitting which makes it readily available for firefighting. The London fitting can be installed in any of our custom tanks.


Rainwater Tank Applications

  • Rural – In Rural communities it is often easier and much more cost effective to have a rainwater tank. Larger style tanks are a convenient option where there’s no water mains supply, the installation of a London Fitting makes the tank a fire tank and is a requirement in rural communities. 
  • Commercial – Having a large tank onsite for the bathrooms and watering the garden makes it a cost effective option but also a fire smart option as the tank can be fitted with a London fitting which allows firefighters to use the water.
  • Residential – A rainwater tank for household water supply is a cost effective option especially in dry times. During a drought it gives you the option of being able to water your garden more frequently and potentially saving the plants from perishing.
