Description:
This report presents a generalized evaluation of the impacts associated with different urban stormwater runoff (UR) treatment techniques. The report addresses the definition of the problem, estimates the volume and characteristics of the UR and the sludges expected, evaluates six methods of UR sludge treatment, and examines alternatives and impacts for UR treatment sludge handling such as bleed/pump-back to the dry-weather plant, and land disposal. Regarding bleed/pump-back of UR sludges, solids deposition in sewers and overload to the dry-weather plant, and land disposal. Regarding bleed/pump-back of UR sludges, solids deposition in sewers and overload to the dry-weather facilities are anticipated to cause problems. The most cost-effective sludge treatment alternative appeared to be lime stabilization followed by thickening, pressure filter dewatering, and landfill disposal. Secondary impacts included costs, water quality, noise, energy consumption, air pollution, and land area requirements.
