ACWA Services Ltd

ACWA is one of the leading UK players delivering innovative sustainable process solutions and technologies for both municipal and industrial clean water, wastewater and bio-solids treatment.

ACWA design and execute resilient cost-effective technologies which address the needs of our clients and their regulatory drivers whilst helping to address climate change.

ACWA provides expert technical products and services to the water, wastewater and industrial sectors. Our expertise combines practical experience with academic knowledge across a wide range of specialisms. These include:

  • Design and build (digital delivery and off-site manufacture)
  • Commissioning
  • Project management

We apply our extensive expertise to help our clients find the best sustainable, cost-effective solutions that meet all their requirements. We serve our wholesale water, wastewater and biosolids markets plus industrial food and beverage clients with their water needs. Our primary specialist areas are:

  • Water treatment
  • Wastewater treatment
  • Industrial effluent
  • Food and beverage


In finding the best solutions we look at innovative ideas and turn them into reality producing some of the most sustainable technological solutions on the market. Our technologies include:

  • Nitreat® Ion Exchange: This is a reversible nitrate removal process by which ions are interchanged between a solid and a liquid with no substantial structural changes in the solid.
  • AquaPyr™ Tertiary Solids Removal Filter: This process is a simple filter that can also remove phosphorous using innovative cleaning technology producing low waste and using less power than other filters.
  • Amtreat® High Rate Ammonia Removal: This process is a high-rate activated sludge process designed to treat wastewater streams and sludge liquors containing high concentrations of ammonia.


ACWA’s in-house design capability is the architecture on which each project is meticulously built. The latest 3D models create precision imaging of all types of installations from a complex water or effluent treatment plan to a single piece of equipment to be integrated into an existing system.

Through in-house engineers ACWA deliver a complete range of technical design and build expertise across projects and programmes of work that include, civil, mechanical, process and electrical, instrumentation and control and automation.


ACWA’s team of highly-experienced project managers, engineers and technicians work closely with clients and key project team members to deliver solutions in an efficient, timely, cost-effective and environmentally-responsible manner.

Project management includes ensuring complete compliance with all relevant regulations, both European, national and where relevant, international, while at all times maintaining a clear focus on the project remit.

Our responsibility is to ensure each project is a complete success, both for our client and for the environment. We actively identify and manage risks, issues, changes to requirements and quality standards to guarantee the best possible outcome.


For hands-on commissioning services, ACWA is an industry leader, focussed on complex water and wastewater facilities for municipal and industrial clients. Commissioning is an essential step in project delivery. Without it we cannot have assurance of a quality outcome. Our in-house team provides comprehensive commissioning services getting involved at project start-up to take the project through planning design, construction and turnover, on time and on budget.

ACWA’s multi-disciplined knowledge and expertise includes, system design, electrical testing, operations and maintenance (incl. training) as well as systems and process diagnostics, providing an authoritative and effective resource.


Our water expertise comprehensively covers the filtration spectrum from conventional strainers and filtration systems to the most advanced reverse osmosis and ion exchange technologies.

  • Microfiltration
  • Ultrafiltration
  • Nanofiltration
  • Reverse Osmosis / Desalination
  • Ion Exchange
  • Conventional Water Treatment
  • Pressure Filters
  • Gravity Filters
  • Chemical Treatment
  • Granular Activated Carbon


The days of wastewater disposal by methods that had no consideration for the implications to the environment are over. As water scarcity increases and the pressure to comply with ever increasing environmental legislation for effective effluent treatment intensifies, it has never been more important to choose the right wastewater partner who can provide a range of effective processes. ACWA can deliver those solutions.

  • Preliminary Treatment
  • Aerobic Biological Treatment
  • Anaerobic Treatment
  • Membrane Bio Reactor
  • High-Rate Ammonia Removal (Amtreat®)
  • Scrubber Effluent Treatment Plant
  • Effluent Re-use
  • Tertiary Treatment
  • Sludge Treatment
