    WCI has more than 35 years of experience in designing, installing and maintaining drainage infrastructure.

WCI are specialist drainage contractors undertaking private and adopted infrastructure works. We deliver combined foul and surface water schemes including deep invert and carriageway works.


WCI designs and builds first time sewerage schemes, foul sewer diversions and new sewer connections and repairs. We are qualified to undertake adopted works as well as delivering private sewers. We also install and maintain rising mains and pumping stations.

We have worked on numerous projects across the country including projects requiring specialist expertise in deep invert, carriageway or combined service installation. We pride ourselves on our efficiency and the quality of our infrastructure.

Surface Water

WCI has developed many surface water schemes ranging from storm water drains to the installation of swales and large scale attenuation schemes. Our expertise extends to land drainage and flood prevention measures and we are often consulted for advice on sustainable surface water management systems (including SuDS and water-related Breeam accreditation).

We have a comprehensive technical understanding of fixed plate orifice and vortex flow control methods. We also maintain in-house technical design capabilities for the design of storage requirements for attenuation schemes.
