|Water Storage & Septic Tanks|
The choice of tank size is selected by owner. Average domestic rain water tanks are 2000ltrs or under. Larger tanks 30,000 L (3m x3m size) cost around $2,800 plus install and consent fees.
The Water Storage component of the programme has a borrowing limit of $20,000. The water storage solutions might also include the cost of system solutions, including pump replacement. HBRC bears no liability for the quality of water stored that is sourced from rainwater or bore supply. This will remain the responsibility of the home owner / consent holder.
Septic tanks can cost more than $20,000 but as the borrowing cap is $20,000 over 10 years, any remaining costs will be paid by the customer.
Water storage is for the collection of rainwater to create a reserve from bore or reticulated supply. Because of public health requirements, it is not designed as a drinking water supply.
The size of the domestic storage tank most commonly used is 2000 litres or less.
The Building Act G12/A5 2 NZ requires a consent if the tank is connected to the potable/drinking water supply. It must also have back flow prevention to protect the network supply, and the work must comply with the Building Code as consented by local city or district councils. If a chartered Engineer has designed the platform, it will be exempt, but any platform must have restraints in place.
Septic tanks should be Oset approved systems and installation should be with accredited suppliers who have completed the relevant training. VTR to be cleared on property sale.
Capturing local rainfall for non-potable purposes (eg your garden) can reduce the demand on the reticulated supply by up to 40% and councils in many areas are already encouraging this. A valuable by-product of rainfall collection is that it also reduces the pressure on stormwater systems.
Reduces effluent leachate into surface and ground water. Improves local stream/river water quality.Increased domestic resilience in emergency event.
