Surface Water Drainage Design

Surface Water Drainage Design At Jgp

Whether developing a Surface Water Drainage Strategy to a buildable level of design or designing a new surface water network from scratch, for a single property site or a new development, JGP drainage engineers can assist.

Comprehensive Surface Water Drainage Solutions

At JGP, we specialise in creating efficient and sustainable surface water drainage designs tailored to your project needs. Water Companies and Planning Authorities typically expect drainage pipework sized for the 1 in 30-year storm event. When storage is required, tanks, ponds, basins, or swales are designed to mimic a greenfield runoff rate for a 1 in 100-year storm event plus an allowance for climate change. In Critical Drainage Areas (CDAs), the requirements are even more stringent. If you already have planning permission and need to discharge planning conditions, we can help move your project forward.

Advanced Design Techniques

For larger sites, our engineers use advanced software to transform topographical and proposed site level and layout information into 3D ground models. Integrating Drainage and Highway Design from the outset ensures optimal outcomes. We determine cover information using the ground model and hydraulic modelling software, enabling us to efficiently design subsurface systems that meet all regulatory requirements.

Adoption by Local Water Companies

Applying for a surface water drainage network to be adopted by the local water company allows developers to eliminate future operations and maintenance obligations. JGP has extensive experience in the adoption process and can assist with all related elements of application and design review. The 2020 “Design and Construction Guidance for foul and surface water sewers offered for adoption” now allows developers to propose certain Sustainable Urban Drainage (SuDS) features for adoption by water companies, further enhancing the sustainability and efficiency of drainage solutions.

Expertise in Brownfield Site Development

JGP excels in developing brownfield sites where space is at a premium. We employ innovative surface water storage or disposal methods to maximise site usability while ensuring effective drainage. Our smart design approaches ensure compliance with stringent regulatory requirements while optimising space and resources.
