Waste water undergoes a multi-step process with the end result being that c.98% of all fresh water is recovered and re-used within a closed system. Both significantly reducing fresh water consumption and ensuring harmful effluent/run-off is successfully removed from the water and collected separately for disposal.

In the first stage of treatment, the waste water from the vehicle wash is fed to a three-stage interceptor, separating heavy metals, oil and other substances from the water. Suspended particles will rise to the top of the interceptor, allowing these to be effectively removed.

The pre-treated water then flows through an advanced water reclamation system involving filtering and backwashing.

The above process applies to all water used by Rainbow including the soft cloth car wash, commercial wash, self-service laundrette and DIY Jet Washes.
