Service & Maintenance

Surveys & Ground Investigation

WCI Consultant Engineers is our design, planning and construction management division.  Our team of professional engineers provide creative and pragmatic design solutions to domestic, commercial and public sector clients.

WCI provides a wide range of groundworks and civil engineering services.  We install all makes and models of sewage, surface water and potable water drainage and equipment with a reputation for completing projects on time and to the highest standards.

Private drainage and water supplies require regular preventative maintenance and the occasional unplanned repair. WCI provide full service and maintenance services to ensure your system is operational when it counts most.

WCI provide specialist drainage surveys and associated ground investigations as part of our integrated approach to providing a complete drainage solution.

WCI is a recognised expert in the UK wastewater industry. We combine consulting engineering services with full turnkey installation and maintenance to provide a complete ‘design and build’ service to domestic and commercial clients.

Serving domestic homeowners, commercial businesses and public sector service providers, WCI brings together disciplines and capabilities specifically associated with off-mains sewerage and surface water management.

Bridging the gap between generalist groundworkers and large multi-disciplinary consulting engineering agencies, WCI provides professional yet cost-effective access to wastewater engineering where multi-disciplinary engineering services are not required. We are engaged by homeowners, small business owners and estates and facilities management teams. We work alongside and are often introduced by architects, surveyors, building contractors and consulting engineers.

If its sewage or water, WCI can help.

The treatment plant serves a large site and we were in regular discussion with the Environment Agency who wished to see an improvement in our discharge standards. After contacting several companies you were the only one to step forward and offer some confident practical advice, I thank you for the straight forward and honest way that you dealt with the issues we faced. You`re methodical approach and attention to detail has enabled the plant to reach its discharge consent limits for the first time since it was installed over seven years ago.
