WPL Diamonds chosen for idyllic National Trust properties

NEWS RELEASE: WPL's Diamond wastewater treatment systems have been installed at a number of idyllic National Trust residential properties in Polesden Lacey, Sherborne St John, Lower Eashing and Outwood. Featuring a compact, conical design, the Diamond requires minimal excavation and no concrete backfill. Once installed underground, only a 600mm cover is visible, allowing the odour-free system to blend discreetly with its surroundings. Ongoing maintenance is also minimal and de-sludging only necessary every 2/3 years.


A range of five Diamond models is available, catering for populations of up to 20 people. Each features a simplistic design with no internal moving parts, enhancing reliability and requiring less than two hours annual maintenance. A unique weir construction ensures continuous high performance by reducing the impact of fluid surges, whilst the extended aerobic process reduces de-sludging and eliminates odours. Meanwhile, a small efficient air blower system also ensures that operating costs are kept to a minimum.

Over 20,000 Diamond wastewater treatment systems are currently installed worldwide – each meeting the high standards of performance testing carried out by the NSF Organisation, a leading international environmental test agency.
