The objective of a wastewater collection system is to convey wastes from the point of generation to the point of treatment or disposal. Pressure sewer systems have been suggested as a cost-effective alternative to gravity sewer systems in those cases where topographic or geological constraints make gravity sewer systems prohibitively expensive or technically infeasible. Design criteria for gravity sewer systems are well developed and readily available. On the other hand, design criteria for pressure sewer systems are limited and difficult to obtain. This report codifies design criteria for pressure sewer systems. The design of pressure sewer systems is accomplished by evaluating the requirements of the two major components of the system the onsite pressurization unit and the offsite pressure sewer main. Design criteria and standards are presented for both the onsite and offsite portions of the system. Onsite facility design criteria include standards for septic tanks and wetwells, pressurization units, onsite piping, and onsite appurtenances. Offsite facility design criteria incude standards for hydraulic design, materials of construction, appurtenances, installation and testing, and special construction requirements. In addition to the specific design criteria, information is also provided on general system design considerations, estimation of design flows, and system costs. The emphasis in each of thee areas is placed on the unique requirements associated with US. Keywords Army Corps of Engineers Recreation Areas. Author
