During the Green Street competition we decided to take up the Council’s Water Retrofit Service Grant scheme. The Council will pay up to $5,000 for the cost of adding water saving schemes to your house. You then pay this back in your rates over 10 years, so only needing to pay ~$5 extra a month. It’s a very easy form to complete with little more than your name, address, property value and the quotes from the Suppliers attached.
We used Paul from Tanks2You (http://www.tanks2you.co.nz/) to provide our tanks, pump and to install them around our house. They’re fully installed now and Paul has made sure that every drop of water that falls onto our house roof and garage roof can be captured to be used to water our garden.
-> OK, to calculate the size of the tank you could fill here’s a calculation (…so get out the calculators):
= 8,915 litres (this is June’s average rainfall, assumes most rain falls in June) x 0.66 x 0.9 x the m2 footprint of your house
So, for a 100m2 footprint house = 8,915 x 0.66 x 0.9 x 100 = 529,551 litre tank can be filled.
We’re really looking forward to some rain now so we can start using them to water our veggies!
