Wynnstay Group manufactures and supplies agricultural products to farmers and the wider rural community across the UK. To service it’s customers, the company runs a large fleet of vehicles which need regular washing to maintain it’s brand image and comply with health and safety regulations.

Until recently, the vehicles had been washed by a single jet wash unit operating at 15-20 litres per minute. The vehicles were washed on a bespoke wash pad with collection drains leading to a two-stage interceptor which in turn fed a reed bed filter system.

The problem they encountered was that the interceptor was too small and the waste water from the jet wash still retained a high chemical and silt content which was having a detrimental effect on the reed beds.

Kirton were called in to find an alternative solution which would cope with the high demands of the business and protect the reed beds. The answer was a totally closed loop water recycling system which cleans and recycles water repeatedly to achieve water saving of around 90%.

Kirton installed a large above ground three-stage interceptor to avoid expensive excavation. The interceptor provides a large storage volume for the wash debris/silt and allows longer settlement time to improve effectiveness. The treated water is then stored in a processed water management tank, topped up by rainwater.

The business is now fully compliant with the environmental regulations and is saving a significant volume of water.
