Headquartered in Northern Ireland, Harlequin Manufacturing is one of Europe’s leading providers of a wide range of specialist products, such as wastewater treatment plants, rainwater harvesting systems, and hot water storage systems. While the family-owned business started with only 3 people in 1981, it has now grown to 105, along with a new state-of-the-art manufacturing facility in East Kirkby. They continue to develope a diverse & innovative product range for clients in the residential, commercial, and agribusiness sectors. We use their products in our waste-water management systems.


Marsh is a traditional, family-owned business who deliver world-class waste and surface water products and solutions. They cater to domestic, commercial and agricultural sectors from their UK manufacturing plants in Kettering and Bridgwater. We use their products, such as septic tanks, grease traps & pumping stations, in our waste-water management systems.

Please note —

Although we would now no longer recommend installing a biotreatment plant from Klargester Wastewater Solutions (Kingspan Water & Energy) over a Harlequin or Marsh tank, we used to be an accredited installer for them so are well-versed in their product range and the subsequent issues that can occur. Advice on such situations and advisable alternatives would be covered under our waste-water management systems.

Allsebrook Pumps

Allsebrook are well-equipped to install, commission, service & maintain all types of clean water & waste water pumping systems. They have over 150 years in the pumping industry so whenever we require pumped or pressurised systems for wellheads, boreholes, rainwater harvesting or dirty water systems we work closely with Allsebrook. Allsebrook then provide the appropriate equipment for any system demands. They can also offer extensive service packages to ensure that systems continue to run without issue. We work alongside them for our storm drainage systems, water schemes and water features.


Many ageing water systems with degraded underground pipework are subject to contamination from both particulates (normally rust) and bacterial agents. Often these are private water systems with unacceptably high levels of (naturally ocurring) chemicals or bacteria in them. Usually these have little effect on people who regularly drink the water, but can be particuarly harmful to the infirm, the very young and the old. Additionally, any visitors are susceptible as they will not have developed no immunity to the contaminated water. Whenever water sampling is required where we are maintaining or installing water systems we would always look to use RMC (Rochester Midland Corp). Along with sampling they can also specify, supply and install the appropriate filters (U.V., particulate and chemical). This ensures that water supplies are safe, practicable and legal. Furthermore, this helps to keep continuity throughout our works.

HD Services Ltd

HD Services is also a family run company, based in Buckinghamshire. Whenever our work requires the creation or renovation of boreholes, we work in conjunction with HD Services.
