Design & Specification


Service & Maintenance


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 surface 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.
