Flood Prevention
Flood Prevention in Ealing and Throughout London
There are 2 million properties at risk from flooding in the UK. Many will be directly affected by rivers overtopping but more homes are damaged indirectly by the backflow of sewage. The causes include severe rain storms, flooding, breakdown of pumping plant and blocked pipelines. The financial losses caused by sewage flooding events are known to be in the region of £30,000 to £50,000 per property. In less than 30 minutes a house or basement flat
can flood with untreated sewage to a depth greater than 1 metre.
All furniture, white goods, electrical, entertainment and personal effects are beyond recovery due to contamination.
Plaster on walls and timber floors will need to be replaced together with electrical wiring and carpets.
The process of drying out can take months, during which the property is often uninhabitable. Contaminated belongings and waste material is removed to a tipping facility where it adds approximately 10 cubic metres to landfill for each affected property. The distress to occupants is beyond calculation. No amount of money can replace possessions of a life time.
Anti Flood Valves
The Forge anti-flood sewer valve we fit has been designed to prevent backflow from surcharging sewers. Wherever there is danger from rising water backing up into a property through the drainage system the valve will close off the backflow automatically to prevent flood damage. In a combined sewer system we recommend that rainwater run off is treated separately until the flooding subsides.
Forge valves have now been used to protect many basement flats and low lying properties previously affected by foul and combined sewers unable to cope with abnormal weather conditions. The valve is float operated forcing a closure of the pipe when backflow occurs. Increased backflow pressure on the flap forces it tighter closed preventing contaminated water and sewage from entering your drain system.
The threat of global warming brings with it forecasts of increased sea and river levels. Coupled with this the need to build more houses on often unsuitable and low lying areas where the risk of flooding is greater can only lead to more incidents of property damage.
