Entranosa is one of the larger community water systems in the State, outside of a municipality, and (as best we can tell) it is the largest cooperative water system, serving in excess of 3100 connections (99 percent of which are residential). In partial fulfillment of its’ stated mission, Entranosa participates in water forums around the State, and provides input to both the Office of the State Engineer and the NM Environment Department on a variety of issues.

The ‘growth’ policy of Entranosa is to provide a clean, safe supply of drinking water to those who need it – if it can, and if such service does not impair service to its’ existing membership customer base. Entranosa is compliant with the primary drinking water requirements of the Safe Drinking Water and the requirements of state law.

Entranosa provides coordination of liquid waste maintenance with members that is compliant with county and state requirements. Participants are set up on maintenance schedules to have their septic tanks pumped on a set schedule, depending on septic tank size, number of people in household, and usage factors. Costs vary based on frequency of pumping and tank size. Entranosa also provides the skills for centralized sewer services, under contract.
