Steady, unplanned growth in rural areas of southcentral Doña Ana County resulted in many homes not having access to a centralized wastewater treatment system. Residents and businesses used on-site systems such as septic tanks or cesspools for wastewater disposal. In some cases, multiple dwellings were connected to a single on-site system. The high density of homes combined with a prominent layer of poorly draining soil caused frequent surfacing of contaminated water and was an immediate threat to public health. The failing on-site systems also posed a potential health and environmental risk from infiltration of wastewater to the aquifer.
This regional project consisted of two phases: 1) construction of individual sewer systems and residential hook-ups for the communities of Vado, Del Cerro, La Mesa, San Miguel, Berino, and Chamberino, as well as construction of a wastewater treatment plant to serve all six communities; and 2) expansion of the treatment plant in 2010.
Phase I (2002-2003):
Phase II project (2010):
It is anticipated that plant capacity will need to be increased to treat an average flow of 2.1 mgd. within the next five to seven years.
The project provided first-time wastewater collection and treatment services to 2,200 residences in six communities, eliminating the health risks attributed to groundwater contamination and untreated sewage run-off caused by failing on-site wastewater treatment systems.
