Integrating innovative SUDS design into the landscape
Sustainable drainage is not a new concept, yet the many benefits of SUDS are still not widely appreciated. Following changes to the planning system in England, all major developments must now give preference to the use of sustainable drainage.
SUDS for new development
Our experience in SUDS dates back to 2003. While working for the Environment Agency, Jonathan Vann reviewed well over 500 drainage systems designed for new developments, advising consultants, architects and engineers on how best to meet the requirements of planning guidance and industry standards for SUDS. Jonathan is also a recognised expert witness on sustainable drainage, having successfully given evidence to planning hearings and public inquiries.
Hydrology in urban areas is not a 'point-and-click' exercise! The hydraulic analysis of SUDS can also be complex and requires a high level of competency in numerical analysis. Our capabilities include:
Drainage reports for planning applications (either standalone or as part of a Flood Risk Assessment)
Preliminary estimates of storage volumes and discharge rates
Options identification and testing
Hydraulic modelling including 1d networks and 2d overland flow routing for studies of system exceedence
Guidance on integrating SUDS into the street scene and wider landscaping
Strategic appraisal of SUDS options to reduce existing flood risk (retrofitting)
Identifying opportunities for water quality improvement, habitat creation and amenity to add value to a site
The retrofitting of SUDS into urban environments can play an important role in alleviating existing surface water flooding issues in our urbanised environment. SUDS nearly always offers a wider range of benefits to the community than traditional drainage systems.
Sustainable drainage design is just as relevant in the rural headwaters of streams which flow into urbanised areas. Catchment-based approaches to flood risk management and water quality improvements can make a significant difference to water quality and flood risk further downstream.
In many small, urban surface water catchments, SUDS may be the only way way to reduce flood risk whilst also improving downstream water quality. Retrofitting SUDS can also offer opportunities to improve public spaces. Our services include:
Hydrological analysis of urban catchments
Appraisal of strategic options for reducing surface water flood risk through SUDS
Identification of opportunities for linking wider benefits, such as improved public spaces, through creative design.
Guidance on policy level approaches to SUDS and community involvement
adapted from CIRIA C753, 2015
We can provide guidance on sustainable rural land management. Sustainable approaches to agricultural drainage can reduce the risk of flooding to downstream communities, improve the health of fisheries, reduce the need for watercourse maintenance and reduce the loss of valuable soil.
