First, we need to remove the existing Wash Bay concrete and remove concrete from the site.
The weather was a challenge with on and off rain.
The 6000 Litre Holding tank is craned into position.
Next, we installed the underground tanks and pits then connected all the below ground fixtures and levelled up the soil ready for the pre-concrete preparation.
All the plastic and reinforcement is laid. We had some sun on this day. The concrete gets pumped in and screeded off. Sun and good weather was helpful!
The helicopter finishes off the concrete. Then the concrete sawing to allow for slab expansion and contraction and clean off the slab making sure it’s tidy around the underground fittings.
Then moving on to site clean up and completing the above ground equipment installation.
Safety barriers and concrete bunding installed to protect the collection pits. Pits have grates and silt baskets inside to stop large debris from passing into the storage tank. And diversion valves fitted so if more than 10mm of rain falls, the control panel activates and the wash bay water is diverted to the stormwater and stops the holding tanks from overflowing and processing through the oil water separator into the sewer.
Oil Water Separator fully installed along with pump station and controller.
Roof built over all equipment to protect from the weather
Mixed use water pumps on the left. Rainwater supply is the dominant water supply with mains water back up when tanks run dry.
Diaphragm pump on the right draws water from the waste storage tanks and pumps it into the 6000 Litre oil water separator.
All of the system runs off a control panel that talks to all machinery so it operates efficiently
Floats and pressure switches all play a role to ensure the system is working to its’ optimum level.
Routine maintenance of the system helps to keep all components running smoothly and the waste water discharged to a level that the Water Authority is happy with.
