Water System

Cucapa is a Kumiai Indian community with a water system serving 33 families (service connections) and a population of approximately 180.  The community is located on Mexican Highway 5 about 56 km south of Mexicali in Baja California Mexico.  The community is provided treated water from Comision Estatal de Servicos Publicos de Mexicali, CESPM, the local water agency.  The community CESPM water service is metered and they pay approximately 50-100 pesos per month for water services.  The community also has a hauled water supply brought in by the Agua Marina Company, for drinking water.  

 The water source is from a canal that is apparently drawn off the Colorado River.  The water is then treated with a coagulant, sent through granulated activated carbon filters, chlorinated with the Accu Tab system, and then sent out to the distribution system via two hydropnuematic tanks.  The community system appeared to have adequate distribution system pressure.

Water System Concerns

The water treatment system seemed to be in good operating order and maintained very well.  Water quality tests show a good raw water supply and low amount of Total Coliform in the distribution system and no presence of E.coli.  The system seems to be in good condition and providing an adequate water supply. However, most community members object to the taste of chlorine in the water and buy commercially produced drinking water, which is readily available.  

Water System Improvement Recommendations

The community water system is owned and operated by CESPM and is in good condition.  No improvements appeared to be necessary.
