Develop an effective strategy for site drainage to prevent flooding, and provide mitigation and management of surface runoff during periods of high rainfall.
The Hydro-Logic® Services team can develop comprehensive Surface Water Management Plans for you and your business.
A Surface Water Management Plan (SWMP) is a plan which outlines the preferred surface water (i.e. the runoff of rainfall from an area) management strategy in a given location.
In this context surface water flooding describes flooding from sewers, drains, groundwater, and runoff from land, small watercourses and ditches that occurs as a result of heavy rainfall.
A SWMP study is undertaken in consultation with key local partners who are responsible for surface water management and drainage in their area. Partners work together to understand the causes and effects of surface water flooding and agree the most cost-effective way of managing surface water flood risk for the long term.
A SWMP for a specific site is usually required to support any Planning Application for new development in the UK.
We provide a full range of services to support SWMPs and Code for Sustainable Homes. We advise on the appropriate sustainable drainage system (SuDS) methods taking due account of site characteristics including soil type, topography and outfall constraints and factoring in the future effects of climate change.
We offer full hydraulic design services for the recommended methods, whether based on infiltration or attenuation. We can also undertake field measurements where required for infiltration-based systems.
Our water engineering services cover all design aspects to allow the construction of a solution to meet the requirements for the provision of drainage and flood risk mitigation infrastructure.
We include a full site assessment to inform the design. With full knowledge of F&WMA, SuDS Standards and Planning regulations, we can solve any drainage or flood problem you are encountering.
Our water engineering related services include:
We have experience in undertaking both Designer and Principal Designer roles under CDM Regulations 2015.
We provide a comprehensive service to de-risk your construction activity through proactive identification of runoff and drainage risks to the surrounding environment, the identification of effective mitigation measures and the monitoring of surrounding watercourses to ensure compliance.
Our services include:
We have undertaken hundreds of drainage assessments for development sites across the UK.
We have extensive experience in analysing, modelling and designing sustainable drainage solutions, enabling development to progress in sensitive areas and greenfield sites through sensitive and effective hydraulic design.
Our Head of Engineering, Alan Corner, is a surface water management and SuDS expert, having worked with CIRIA on the 2015 revision of the SuDS Manual and assisted DEFRA in drafting the National SuDS Standards.
