Our Auckland team designed and built a custom wheel wash for an apartment project in Three Kings.
Fletcher Living’s Three Kings development is a brownfield former quarry site on a busy road. We were keen to find a safe, sustainable way to wash down vehicles leaving site so we don’t use more water than we need to, mess up the road or pollute the stormwater.
The solution we came up with was to lay a concrete pad and build a spray system with fixed nozzles. The truck drives up and the Gateperson presses a button to start the spray – a less labour-intensive system than the more common approach of having them clean off the wheels with a pressure washer, and one that means that Gateperson doesn’t have to walk around the vehicle and doesn’t risk getting soggy!
The really clever bit is where the water comes from and where it goes to – we’re using a rainwater-fed holding tank to supply our wheel wash. The used water drains to a cesspit that fills up and then overflows to a catchpit, then the water is pumped back to the holding tank. When the cesspit is full of silt, mud and other assorted gunge, we’ll get a sucker truck to clean it out. We’ll test the water at the end of the project and check whether it can be safely released or whether it needs to be removed with a sucker truck.
Either way, we’re using a lot less water, keeping the Gateperson safe and dry, protecting the road and the drivers using it, and keeping runoff out of the stormwater system.
