Schemes for which we have been responsible for cater for populations from 1,000 to over 1 million. These plants include those supplying major cities and catering for expanding domestic and industrial demands. 

Services include water quality analysis; assessment of treatment processes and systems; development and monitoring pilot plants; design of treatment facilities, including process, civil, building and, mechanical and electrical systems engineering. 

We employ specialists in all areas of plant design, including process, civil, hydraulic and mechanical/electrical engineers and environmental experts enabling us to provide a fully comprehensive service.
