Integrated Planning for Wastewater Treatment and Recycling for a Small Community Development

Abstract

Integrated water resources planning was conducted for Olowalu Town, a proposed development in western Maui, Hawaii. Total water needs, which can be supplied by a combination of diverted surface water, well water, recycled water and captured stormwater, are estimated at between 1 and 2 mgd. The Olowalu development will generate approximately 0.5 million gallons per day (mgd) of municipal wastewater. That wastewater can be recycled for beneficial use and irrigate between 80 and 120 acres depending on the amount of storage provided and the type of water reuse.

Pharmaceuticals and personal care products in passive samplers at seven coastal sites off West Maui, Hawaiʻi:

“…The Olowalu Beach site is located approximately 13 km south of the main study area and represents a coastal site with minimal anthropogenic effects, owing to a lack of substantial recent development. The possibility of legacy contaminants at Olowalu (following the cessation of sugarcane operations in the late 1990s) may still represent a source of land-based pollutants, although this was chosen as the "pristine" site (Crites, 2006). Watersheds that drain into these seven sites contain a variety of land use types, including marinas, resorts, agricultural, and residential areas.…”

The use of passive membrane samplers to assess organic contaminant inputs at five coastal sites in west Maui, Hawaii

“…The Olowalu site is located ~13 km south of the main study area and represents water with minimal anthropogenic impact owing to lack of development, although the possibility of legacy contaminants following the cessation of sugarcane operations in the late 1990s may still represent a source of land-based pollutants (Crites, 2006). Watersheds that drain these sites contain a variety of land-use types, including marinas, resorts, agriculture, and residential areas (table 1).…”
