Approximately 90 percent of the population in the south central area is connected to one of the several community water systems, known as Mutual Domestic Water Consumer Associations. The rest of the community obtains drinking water from privately-owned wells. There are, however, no community wastewater systems. Residents and businesses use on-site systems such as septic tanks or cesspools for wastewater treatment.
It is suspected that because of the shallow groundwater table, a large source of groundwater contamination results from agricultural and onsite liquid waste disposal systems. Furthermore, the high density of homes combined with a prominent layer of poorly draining soil causes frequent surfacing of contaminated water and is an immediate threat to public health.
This regional project consists of two phases: 1) construction of individual sewer systems and residential hook-ups for the six Doña Ana County communities listed above, 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.
This regional project addresses the existing threat to public health by eliminating the use of on-site septic tanks and cesspools and constructing the necessary infrastructure to provide first-time wastewater collection and treatment services to the residents in the above mentioned communities in Doña Ana County, New Mexico.
