Our general advice on purchasing the correct stormwater system is to calculate the volume of the soakwells based on the roof area (catchment area) and the formula for predicted rainfall during a storm from your local or nearby council.


When choosing a location, the soakwells should be at least 1.5 - 1.8m from footings and boundaries, depending on your council. Never start digging until you know where all your underground services are (sewer / gas / power / water / phone / fibre etc).

You can contact Dial Before You Dig for free to find out about the underground services on public land and we have some tips for you as well.


To maximise the area in contact with the sand and take advantage of the design, polypropylene soakwells are ideally installed in rows in only two or three locations.

This is important because downpipes can take different amounts of water from the roof at different times due to the fall of the gutters, direction of the wind/rain or maintenance issues.

We always aim for just two locations, a row of polypropylene soakwells at the front and back of the house. This is dependent on factors including available space and the location of underground services as well as the distribution of roof area.

  Tip!  Halve the number of 140 polypropylene soakwells to find out the total length! eg. 12 soakwells=6m long (W x 0.5m, D x 0.9m).


For the piping, walk around your house and draw a rough plan of the boundary, house perimeter, downpipes and proposed soakwell locations.

Pace out the length of pipe required from the furthest downpipe to the soakwells. The fall for the pipe is 100mm for every 10 metres. Cut a hole in the top of the soakwell for the pipe. Make sure you glue the fittings and pipe.

You should use grates under the downpipes to prevent water rising up the downpipes in any situation and to allow the system to breathe for optimal flow.


Don't forget you will have the sand displaced by the soakwells at the end. To estimate the amount take the total volume of the polypropylene soakwells and add another 30%. We have some tips on how to deal with this as well.
