WRRCTR No.63 Wastewater Effluents and Surface Runoff Quality

Abstract

A three-year study was conducted to determine the quality of domestic wastewater treatment plant effluents and urban surface runoff, including street litter, on Oahu and to examine the reclamation potential of these water resources. The study was conducted in three phases: 1) the examination of effluents of eleven wastewater treatment plants representative of conventional treatment technology, 2) the characterization of street litter and of runoff from a watershed representative of runoff from varied land-use patterns, and 3) the fabrication of a reverse osmosis pilot module and preliminary evaluation of its potential to reclaim secondary sewage effluent.
