Constructed reed beds clean up storm overflows on small wastewater treatment works
Severn Trent Water is required to treat stormwater overflows that occur at sewage treatment works before discharge to receiving water courses. Where the regulator sets numeric quality standards on stormwater discharges from works serving populations of <2 000, treatment is provided in constructed reed beds. By June 1994 the company had 55 sites with reed beds for stormwater treatment and expects to provide more as an asset renewal programme continues. The paper describes discharge consent issues that are emerging and details the operation of the reed bed systems. Results from three surveys carried out during storm events show the benefit of the systems in reducing discharges of BOD5, TSS, ammonia N, and TON. A tracer study was carried out on one survey and the results are fitted to a simple mathematical model.
