At GCA (UK) Ltd - Consulting Engineers we provide drainage solutions for storm and foul sewerage design.


These range from simple gravity-fed sewerage networks, to the feasibility and design of pumping stations and balancing facilities. These can be used to determine peak flows and ensure a highly efficient system.

Our Engineers keep abreast of current design philosophies to achieve optimum solutions in terms of SUDS (Sustainable Urban Drainage Solutions). They adopt the latest balancing techniques to achieve Environment Agency and Water Authority approvals.

The Environment Agency recognises the damage caused by historic conventional drainage systems and advocates an approach that replicates natural systems as far as possible.

Sustainable drainage can offer cost-effective solutions that are easy to manage, attractive and resilient to heavy use.

Early discussions with the relevant authorities are essential to fix agreed solutions and optimise preliminary costings, an area often overlooked at project feasibility stage.
