Water and waste

Protecting our water resources and managing waste is vital to the long-term health and wellbeing of our communities. 

Interserve works with the water and waste industry to manage finite natural resources more effectively, and develop innovative ways to reuse, recycle and prevent waste.

We do this by listening to communities, and working with them to address their needs. Our ability to think differently enables us to design better approaches to delivering water and waste services.

Water and wastewater

Water companies are under immense pressure to improve standards, minimise environmental impact, reduce leaks and bring down the cost of water supply.

Interserve draws on more than 70 years' experience to help clients achieve a more effective, sustainable and cost-efficient service. Our in-house engineering team builds best-value water treatment facilities, integrating recycling and energy generation processes to minimise waste water.

We design, construct, procure, install and commission:

  • Drinking and waste water treatment plants
  • Waste water treatment plants
  • Pumping stations
  • Sludge treatment
  • CHP plants
  • Combined storm overflows and sewerage pipelines.

Solid waste

The UK must dramatically reduce the amount of waste sent to landfill to meet tough EU targets. As the push towards a ‘zero waste economy’ gathers pace, the waste management sector must overcome financing barriers to increase capacity.

Interserve helps clients find innovative ways to finance projects that reduce, reuse, recycle and generate energy from waste. Our in-house capabilities include the construction, design and maintenance of solid waste treatment facilities such as:

  • Materials and household waste recycling centres
  • Odour-controlled, fire-protected waste transfer stations
  • Mechanical biological treatment facilities with anaerobic digestion
  • Gasification plants.

As one of the few Engineering, Procurement and Construction Contractors in the sector, we guarantee the quality of our work for public and private sector clients and have a proven track record of delivering projects end-to-end, on time and to budget.
