Water Resource Management (WRM) is the process by which all elements of the water cycle are considered within a project. It is increasingly important that water is considered as a single, finite resource. A Water Strategy developed after a WRM may include Sustainable Drainage Systems (SUDS) measures; a foul drainage strategy plus a Flood Risk Assessment (FRA) report or summary. Our team has expertise in all these aspects of drainage and storm water management.
We develop integrated urban drainage strategies to balance the needs of flood control and water quality with amenity aspects such as water resources, landscaping potential and creation of wildlife habitats. We address the weaknesses inherent in conventional drainage systems that rely on underground pipes to remove surface water run-off. This can allow untreated water to flow directly into rivers or groundwater leading to flooding if surface routes or blocked drains cannot cope.
Where possible SUDS enable rainwater to naturally drain into the subsoil and reduce the risk of ‘nonpoint source’ pollution caused by runoff flowing over the land picking up pollutants. SUDS use a variety of techniques to manage runoff flow, including porous pavements, swales, balancing ponds and passive treatment systems.
Out team carries out condition assessment of flood defence assets plus feasibility studies, cost benefit analyses and we offer strategic advice for flood defence works. We address detailed river edge design and site supervision. We take a strategic approach to detailed design of hydraulic control structures including weirs, monitoring stations, sluices and outfalls. We use hydraulic studies including assessment of flood water levels, flood storage and defence and hydraulic engineering of country parks, gardens and heritage properties.
