The Bureau of Indian Affairs (BIA) operates a nine month school for 900-1,000 Indians at Chemawa, approximately two miles north of Salem, Oregon. The waste treatment plant for the school is unique in this area, consisting of a facultative mechanically aerated lagoon followed by a two-acre polishing pond and chlorination. A sampling program was established to determine raw waste load and characteristics; solids and BOD removal in aerated lagoon; sludge accumulation in aerated lagoons; MPN level in aerated lagoons; Adequacy of aerator for mixing and oxygenation; effect of polishing pond on BOD, DO, MPN and SS; effect of chlorination on BOD, DO, MPN and SS; and operation and maintenance costs and requirements.
