HIGHWAY RUN-OFF TREATMENT MOVES STREETS AHEAD
•Stormwater Management’s D-Rainclean™ sets new performance level for removal of surface water pollutants.
•Low-maintenance modular design adaptable to any trafficked application
The unique filter medium within Stormwater Management’s new D-Rainclean™
bio-remediation infiltration channel has achieved class-leading performance
for the removal of pollutants from contaminated surface water run-off generated by heavily trafficked highways and car parks. In independent tests carried out under stringent DIBt standards for soil and groundwater protection,
the D-Rainclean system was shown to have performed to the discharge quality requirements of the Water Framework Directive, giving the porous channel’s medium an expected operational life of between 15 and 20 years.
“The test results have been particularly welcomed by the regulators as treatment and infiltration at source is the most desirable and cost-effective method
for processing polluted run-off as part of a sustainable drainage solution,” says
Neill Robinson-Welsh, Technical Sales Manager at Stormwater Management
Ltd. “D-Rainclean can eliminate the need for stormwater attenuation and
complex downstream treatment. The result is a virtually maintenance-free,
cost-effective installation that gives assured cleaning performance for up to
two decades.”
Manufactured from robust polypropylene, each D-Rainclean™ channel section is 500mm long and fitted with a 300mm wide cast iron inlet grating
rated to either Load Class B125 for light traffic areas or D400 for heavy
goods ve X
