H20 Water Management

 The Stormpod system offers:

A fully sustainable alternative to existing crate/box type systems. Having a fully accessible 315 mm dry weather channel running through it , making jetting and cleaning simple. The Stormpod’s shape and design strength make it an uncompromising lightweight alternative to larger diameter concrete pipes. Being able to be installed in granular surround in the most difficult of ground conditions, such as high water tables and running sand.  With a simple connection, it can be installed quickly and effectively with the minimum of plant and labour, competing favourably with heavier pipe and plastic twin wall systems. It’s simple but very effective sealing system takes a huge amount of labour and expense ensuring you make a watertight seal on every joint. With the Stormpod there is no need for caulking, welding, membranes or expensive band seal couplings.

How does Flooding Occur?

Flooding usually occurs when there is an increased flow that cannot be managed by the existing drainage system. This increased flow can be created by either a high storm intensity or new developments where large roof areas and impermeable hard standing is constructed. This usually equates to the existing drainage system being put under pressure by the increase of storm water charging the pipe work. If the drainage pipe work system is not adequately sized then the water pressure can either burst the pipes or create backup in the drainage system. Storm water then rises up through the manholes and gullies to ground level, in so flooding the surface area and in the worst cases if the water continues to rise, then severe flood conditions can prevail. Further problems occur when foul water systems also flood and mix with the surface water drainage and then raw sewage becomes suspended in the flood water which can cause disease. As well as flood control applications the Stormpod is easily adapted for use in commercial and larger domestic rainwater harvesting  applications.

Rainwater from roofs and specified surface areas is  treat by one of our unique filter systems. For roof areas the water is filtered through a simple 600mm filter chamber as shown opposite. For surface water treatment we recommend using one of our Silt   Guardian or Geoceptor separators upstream. Once the rainwater has been filtered then it is stored in the pod system before finally entering the control    chamber, which consists of a high performance pump and telemetry system which controls the distribution of the stored water to the specific appliances. The  standard control package will deliver up to 3000 litres of water a day. If necessary we can supply much larger control systems on request. Booster Pumps and pressure vessels may be required on larger developments. For more sensitive applications we can provide ultra violet filtration which will maintain a very high level of water quality. 

Combined Sewers

Combined sewerage systems exist in many older towns and cities and there are still a massive amount of combined sewers that emanate from homes or businesses across the UK. These systems also collect the storm water run off from the surface areas and roofs. Since this type of combined collection system includes both rainwater and sewage it is referred to as a Combined Sewer System or a CSS. The Stormpod is ideal for connection to support CSO’s being designed to provide surface water attenuation on developments with larger surface areas that are connecting into a CSS, particularly where the increased flow to the sewer could cause surface flooding. Surface water enters the Stormpod system, either through a collection chamber from a number of different areas as shown above or directly into its 300mm inlet pipe. Because the outlet on the Stormpod can be reduced to a 100mm pipe, or even further using a flow control or orifice plate. This regulated flow will force the surface water to back up and be stored in the designed Stormpod system and at the discharging CSS manhole the regulated flow supports the prevention of surface flooding, which includes dangerous sewerage.
