Manzanar Relocation Center

Outlying Area
Sewage Treatment Plant

Figure 8.109. Clarifier at the Manzanar sewage treatment plant.

The sewage treatment plant, located about 1 mile southeast of the relocation center residential area, was connected to the relocation center via a 4,600-foot-long sewerline. Manholes were spaced along the pipeline at 100 foot to 300 foot intervals, but many of the manholes have been destroyed.

Evidence of all of the sewage treatment plant structures remain (Figures 8.108 and 8.109). The control room remains consist of the 3-foot high raised concrete slab foundation of a three room structure measuring 30 feet east-west by 60 feet north-south. There are remnants of a decorative rock alignment on the north side of the foundation. North of the control room foundation, there is a series of concrete tanks of various proportions connected by 18-inch diameter concrete pipe which totals about 220 feet in length.

Figure 8.108. Control room and digester at the Manzanar sewage treatment plant.

The digester is an enclosed tank 42-1/2 feet in diameter and 19-1/2 feet high. The clarifier is a partially buried, round open-topped tank approximately 65 feet in diameter, with an interior depth of about 11 feet. One side of the tank is broken out, and all equipment has been removed. The chlorine tank is a rectangular concrete box measuring 36-1/2 feet by 16-1/2 feet, and extending 4 feet above the ground surface. Other remains at the sewage treatment plant include a concrete enclosure for a small pump, possible light fixture foundations, four rectangular settling ponds grouped together to form a larger 100-foot-by-200-foot rectangle, and an earthen ditch that carried treated sewage towards the Owens River.
