Stormwater attenuation tanks and pumping
systems
A new range of Stormwater attenuation tanks and a range of high capacity pumping systems have been launched by Klargester.
Klargester has launched a new range of Stormwater attenuation tanks and a range of high capacity pumping systems, both designed to complement its existing series of sustainable urban drainage solutions (SUDS) products Stormwater run-off and an increased risk of flooding is becoming a huge challenge for developers

In addition to increased rainfall and rising sea levels caused by global warming, demand for housing is such that urban development is extending onto marginal areas around river valleys, where the increase in hard surface areas (roofed areas, paths and roads) causes higher volumes of rainwater to flow into the watercourses.
Attenuation systems, including tanks and rainwater harvesting systems, are designed to manage peak flow rates in storms, by attenuating excess flow on site for the duration of the storm and then releasing it at a specified reduced flow rate, after the storm.
Along with separators (to remove oil contaminants from discharges) attenuation systems are a requirement under SUDS policy for all town and city developments.

One solution which is currently popular with developers is a water feature or large pond, however, the new Klargester Stormwater Attenuation System is easier and cheaper to install than either of these options.
Furthermore, Klargester Attenuation tanks are installed below ground, increasing land availability.
The system includes both in-line and off-line attenuation tanks.
The in-line systems are designed to allow the water to back up through the tank and drain by gravity through the flow regulator.
This system is suitable for installations where a fall through the system of 2.5 metres can be accommodated.
The off-line systems have the flow regulator in a separate chamber and allow the rate to build up and overspill into an adjacent storage tank.
"We currently offer market-leading solutions in rainwater harvesting and separators, now we are increasing our range of pump stations and attenuation tanks, all of which will provide a modular system for developers that delivers best practice in SUDS," says Kevin Roe, Klargester's UK sales manager.
"Not only does this add to Klargester's product portfolio, it also adds weight to the Kingspan Group's overall effectiveness in supplying sustainable construction solutions to the industry." Roe continues: "The advantages of using attenuation tanks are that they're easier to install and they can be buried deeper underground than crates, or under car parks.
A tank may also mean buildings sell quicker, which obviously helps increase profit for the builder." Pumpstor24 is a range of pumping stations with high capacity for 24-hour storage that offer the capability of expansion to meet the demands of most applications.
The 2.6 metre diameter station is extremely robust, made of GRP with 8 mm nominal wall thickness and reinforced ribbing.
It incorporates a pump sump at one end.
In a high level situation, effluent passes into a built in holding tank from the sump.
At low levels, a non-return valve allows the flow to return to the sump when the system becomes operational again.
Benefits include Pumpstor24's ease of installation with shallower excavation than concrete pumping stations, and its easy-maintenance features.
Cleaning of the tank, for example, is made easier by particle screening, which prevents floating debris and grease from entering the storage over-flow tank from the pump sump.
And there's even easy access for cleaning the particle screen, with a simple connector for a hose.
Pump sizes vary from 0.35kW to 12kW for a standard package pumping system.
Says Roe: "Specification by Municipal Agencies has increased over the years, so emergency storage requirements have become a mainstay for most applications in line with current legislation.
Local Authorities and Municipal Agencies are looking to the future and packaged systems rather than bespoke design, and build units are becoming a requirement.".
