SuDS for Stormwater Control
Sustainable Drainage Systems (SuDS) have been introduced following the increase in urbanisation, which has increased flash flooding after rainfalls.
To combat these problems, the Environment Agency has been promoting the use of sustainable urban drainage solutions (SuDS). The Planning Policy Guidance Note 25 for England on Development and Flooding, emphasises the role of SuDS and introduces a general presumption that they will be used. SuDS will probably feature increasingly in such guidance documents, as they are revised.
SuDS is a process for achieving integrated surface water drainage design with the objectives of:
Our range of surface drainage products have been developed to try and replicate the natural drainage systems, using cost effective precast solutions:
Circular Pipes
Rigid precast pipeline systems with flexible joints are used for the conveyance of storm-water and foul-water. Perforated pipes enable storm-water to percolate into the ground
Ovoid Pipes
An egg shaped pipeline system that has better velocity characteristics at low flow than equivalent circular pipes
Flat Pack Tanks
Modular attenuation tank systems, made from precast panels produced under factory conditions
Sealed Manholes
An off-site watertight solution pre-benched and configured to the required inlet/outlet orientation, ensuring less wet wells on site
Soakaways
Perforated chambers which may be open void (providing storage) or contain filter medium (providing treatment) to facilitate percolation of stormwater into the ground
Hydro-Brake Optimum® Flow Control Chambers
Hydro-Brake Optimum® chambers are pre-installed with flow control devices such as a penstock, non return valve, weir wall or an orifice plate,
Road Gullies
Designed to receive stormwater runoff from paved surfaces and first-line gravity separation of silt.
Direct Access Pipe Systems
An off-site manhole for large diameter concrete pipes system that completely removes the need for a traditional manhole, any on-site benching or concrete surround. The system incorporates the highly successful and SA7 approved Sealed Manhole joint system
Hydro Downstream Defender® Separator
The most advanced hydrodynamic vortex separator available for the removal of sediment, oil and floatables from stormwater runoff
Catchpits
Used for the gravity separation of debris and silt to prevent them passing downstream, the watertight one-piece structure offers greater design flexibility with a range of core or pre-formed hole/cut-outs for inlets/outlets which come complete with seals
Headwalls
Designed for connecting swales, ponds, detention basins etc in to underground pipes, with the use of inlets and outlets, headwalls are available with flap valves and grills.

SuDS is a process for achieving integrated surface water drainage design with the objectives of:
- Reducing the risk of flooding from developments
- Minimising pollution arising from surface water runoff to groundwater
- Maintaining recharge to groundwater
- Better use of water resources
- Improvement to water amenity & biodiversity
