WHIPSNADE’S RHINOS WALLOW IN WPL’S RECYCLED RAINWATER

Posted: Friday 24th April 2009

WPL’s rainwater harvesting system is creating a splash at ZSL Whipsnade Zoo’s new ‘Rhinos of Nepal’ exhibit. Home to the Zoological Society of London’s herd of greater one-horned rhinos, the Ł1 million indoor facility has temperature controlled wallowing pools and showers fed with harvested rainwater from a 30,000 litre underground storage tank from WPL’s Rain Sustain range. The rainwater harvesting system, installed by Bedford-based Alpheus Environmental, is reducing the Zoo’s consumption of mains water - bringing both financial and environmental benefits - and provides a ‘green’ supply of recycled water for the rhinos to enjoy.

The WPL commercial rainwater harvesting package at the Zoo collects rainwater from the rhino enclosure’s roof, which is then filtered and stored in an underground tank ready for pumping into the facility as required. The system includes an AF150 automatic rainwater utilisation system, featuring two low noise self-priming pumps and related controls.

Andrew Baird, WPL’s Business Development Manager, says: “We’ve liaised closely with our installers to develop a range of rainwater harvesting solutions to suit individual customer requirements, from public buildings such as schools, hotels and offices, to more unusual applications, like the system for Whipsnade Zoo.”

WPL’s commercial rainwater harvesting range, Rain Sustain, is suitable for a wide range of business and large domestic applications. In conventional systems harvested water can be used for toilet flushing, laundry, watering plants and other general cleaning. Tank sizes in the commercial range offer capacities from 13,000 to 200,000 litres, while, for smaller business or domestic applications, the Rain Retain range includes models from 2,700 to 13,000 litres.

Prior to this new rainwater harvesting system, Alpheus Environmental had worked with WPL to install extensive wastewater treatment facilities throughout the animal enclosures at ZSL Whipsnade Zoo. Alpheus specified WPL’s HiPAF treatment plant for the wastewater project, which is designed to cope with variable flows and loads and offers reliable operation and a standby facility. Alan Rowland, Project Engineer at Alpheus Environmental, comments: “WPL offered the right range of products to meet the water and wastewater challenges of our client. We valued their expertise in specifying and helping us to provide a solution that satisfied our client’s environmental obligations and provided a good return on investment.”

The company also has ongoing service and support contracts with an extensive customer portfolio including the UK’s major water utilities, commercial and industrial users and all sectors of the domestic market.
