Abstract |
One of the causes of pollution from stormwater overflow of combined sewers is the deposition of pollutional solids during dry weather flow followed by pick up of the pollutional material during storm flow when the flow be bypassed. As a solution to this problem, it has been proposed that a flushing system be used to periodically cleanse the sewers during dry weather and convey the solids to the treatment plant. A study was made of sewer flushing practices, application requirements, and hydraulic theory. Investigation was also made of sampling methods and equipment; flushing test equipment was designed and the cost was estimated. The existing information on sewer flushing has indicated a good possibility that a periodic flushing system would be feasible for reducing pollution from combined sewer stormwater overflow. The design of flushing evaluation equipment has been carried to the point that cost estimates can be made for construction of the equipment. A description of the design and the cost estimates are included. (WRSIC abstract) |
