Design of Septage Treatment Facility in one of the State Universities in the Philippines

Abstract

This study responds to the mandate set forth by RA 9274 or the Clean Water Act of 2004, proposing to design a septage treatment facility in CPSU Main Campus, Kabankalan City. Data was gathered by calculating the number of students enrolled, the non-students who stayed in the boarding houses, and the consumers of the CPSU Water System. Numerical factors from the Environmental Engineering book were combined with the data gathered to produce the septage and BOD loading rates. The septage and BOD loading rates, together with the equations of open–channel and cantilever retaining walls, determined the sizes and hydraulic capacity of the ponds and tank. The septage will go through a series of ponds while undergoing the natural treatment process and will be released as a clean effluent to the ground. In contrast, the dried sludge will be released as a soil conditioner of fertiliser.
