Surface water management solutions from JDP
Choosing the right solution for each project is dependent on sound expertise, which is based on the ability to identify and design efficient integrated SUDS. The objective is to design a system to deal with the flow at source, rather than transferring the problem further down the watercourse.
JDP’s dedicated technical design department uses the latest technology in hydraulic modelling, which calculates accurate rainfall data for each area, enabling the design of bespoke systems for each project, producing CAD drawings and providing a 24-hour turn round take-off to ensure compliance with building regulations and save time and cost.
SUDS design may include a range of solutions, which provide the site with infiltration/soakaway (allowing water to soak into the ground), or attenuation/storage (store, slow down and control water flow). Using a bespoke approach and combination of products will ensure a system that offers the best solution for each project.
Infiltration / Soakaway
Modular crates wrapped in a permeable geotextile for soakaway, provide capacities from 190 litres to an infinite size. A range of crates is available each with a different load specification.
Lite, Heavy and Extra crates can be integrated together on an installation, resulting in a hybrid modular system containing all three versions or just Heavy and Lite which accommodates the differing burial depths, offering significant cost saving in some applications.
Inspectable Crate Systems
Inspectable Crate Systems control heavy rain and gradually return it to the natural watercourse as if the storm never happened. Not only do they prevent flooding but help to protect the local environment too. The modular inspectable crate can be used as either an infiltration or attenuation system where its adaptability means it can be built to any size or shape to a deep burial depth and use in heavily trafficked areas.
Attenuation / Storage
Modular crates continue to lead the way in attenuation. Wrapped in a non-permeable membrane and protective fleece (needle punched fibre geotextile) for storage, they provide capacities from 190 litres to an infinite size.
Large diameter HDPE pipes are a tried and tested method for carrying stormwater underground. To form a tank structure they include welded end plates and can also include manifolds to join individual lines together.
Flow Control Valves
Flow Control Valves are available as individual units (in stainless steel or plastic) or complete with chamber (in concrete or HDPE) to bespoke design as part of a SUDS system to control the rate at which stormwater leaves a particular site. A typical application of these valves is to control the flow from storm water attenuation/ infiltration tanks preventing downstream flooding during periods of heavy rainfall.
Stormcheck Vortex Flow Control Chamber
These HDPE plastic chambers are made to specific requirements according to the application, providing a sealed chamber ready to install complete with a stainless steel flow control device. This makes the Stormcheck Chamber one of the easiest products to install.
Maintenance of SUDS solutions is one of the key focus points in today’s product development and solution design. With its innovative and unique sliding vortex chamber for inspection and maintenance, the Hydro-Valve Slider is one of the best products of its type. A range of standard curved design valves suitable for 1050mm, 1200mm and 1500mm diameter chambers of any material, with large manhole options up to 3000mm diameter. In addition a flat wall version is also available.
