Why choose us
WPL System Service Specialists
Expert WPL Sewage Treatment Plant Servicing
CPD Waste Water Ltd provides specialist servicing and repair for WPL (Water Plus Ltd) sewage treatment plants across Hampshire, Surrey and West Sussex. WPL systems — including the Diamond and Airflow ranges — are well-regarded for their robust construction and are found across a wide range of rural and semi-rural properties in our service area.
WPL sewage treatment plants use an extended aeration process with submerged fixed film media to treat domestic wastewater. The Diamond range in particular is known for its compact design and suitability for smaller plots. Like all treatment plants, WPL systems require annual servicing to maintain the blower, inspect the media, remove accumulated sludge, and ensure the system continues to produce a compliant effluent discharge.

WPL Sewage Treatment — Frequently Asked Questions
How often should a WPL Diamond be serviced?
WPL recommends annual servicing for all their treatment plants. This is also a standard condition of Environment Agency discharge exemptions. We recommend booking your service at the same time each year to stay compliant.
Is the WPL Diamond suitable for a small rural property?
Yes — the WPL Diamond is specifically designed for smaller properties and restricted installation spaces. It's a popular choice for rural cottages and single dwellings across Hampshire and Surrey.
My WPL system alarm is sounding — what should I do?
Call us immediately on 01252 985722. An alarm typically indicates a blower fault or high water level, both of which need prompt attention to prevent untreated effluent discharge.
Do you service WPL Airflow systems as well as the Diamond?
Yes. We service the full WPL range. Call us to discuss your specific model and we'll confirm we can help.
