Fully Integrated Systems Installation


Choose a tank 

Size tank required for Fully Integrated = Rainwater Harvesting calculation + Municipal Back Up calculation.

Roof p/m²

Tank Size

50 – 100

750 L – 2200 L

200 – 400

2500 L – 10 000 L

Size of tank = litres p/day X total days back up required i.e. 4 people (600L) X 3 days = 1800L

Tank placement

Will depend on space available plus access to suitable guttering/downpipes and main incoming water supply line.

Base / foundation options

Tanks must be installed on a sound, level and smooth surface. Level paving will suffice, or a properly designed tank stand, alternatively a concrete plinth needs to be built. Ideally the plinth should be covered by a concrete topping at least 85mm thick.



1. Base / concrete plinth

Ensure tank is installed on a suitable base. The base must be sound, level, smooth, free of any protrusions and at least 100mm wider than the base of the tank (refer to pre-installation).

2. Select pre-filtration

Select desired pre-filtration options. Pre-filtration will differ depending on preference and what the water will be used for.

3. Install pre-filtration

Install desired pre-filtration. For detailed instructions refer to steps 3 and 4 on Rainwater Harvesting installation page.

4. Cut a hole in the tank lid

Cut a hole of 110.5mm in the middle of the lid and fit the pipe through the hole, stopping before the mesh/tank screen.

5. Instructions for plumber

For detailed plumbing instructions please refer to steps 2 to 5 on Municipal Back Up installation page.

6. Install the filter

Install desired filtration unit between the pump and the house.
