Southeast Collection System - Final Phase

We are excited to begin our final phase of the Southeast Collection System Project.  The project is currently at 95% complete for design and is being reviewed by the funding agency. This phase is expected to begin construction in Winter of 2021. The construction will include the installation of approximately 55,000 Linear Feet (LF) of 4 ‐ inch, 6 ‐ inch. 8 ‐ inch, and 10 ‐ inch vacuum sewer pipe and related infrastructure including vacuum calve pits and buffer tanks. There will be over 500 new sewer connection that will be installed including service piping, wyes, cleanouts, air terminals, and septic tank abandonment.

This project will provide over 600 homes the option to connect to the sewer system and have their septic tank or cesspool removed. The project has received $15,252,100 in funding with $11,026,100 in grant funds and $4,226,000 in a low cost loan. The funding for this project will include covering the cost of the impact fee or decommissioning of septic tank and cesspools for customers in the project area for over 500 homes. Starting March 1, 2021, the Association will begin accepting applications for homeowners who wish to connect to the system. The grant funds that will pay for the impact fee, decommissioning of the septic tank or cesspool, as well as the customers connection to the system will be granted on a first come first serve basis. Once we run out of funding for that part of the project any homes who wish to connect will be required to pay the full connection and impact fee as well as hire a certified plumber to complete the work on their private property.  Below is a brief presentation on the project. Please contact one of our Customer Service Representatives for more information on signing up for service.

Dona Ana Water Tank Rehabilitation

We have recently finished the planning and design for the rehabilitation of the four water tanks in Dona Ana. Due to the age of the tanks (20 to 35 years), our engineers have recommended that all four water storage tanks be sandblasted and recoated with an epoxy-based coating for the interior and a polymer-based coating for the exterior surfaces. These tanks provide the water storage for over 4,000 homes in our service area. It was also recommended that an investigation of the current corrosion levels should be completed for each of the tanks during construction in order to determine the necessary replacement, if any, of steel components prior to recoating. The funds have been secured for the construction portion of this project. This project is expected to begin constuction April 2022.

Dona Ana Village Liftstation and Forcemain

The funding for the project is through the New Mexico Finanice Authority Colonias Infrastructure Board. The Dona Ana Village Liftstation and Forcemain project is curerntly in the planning and design phase. This project is for the rehabilitation of the existing lift station, force main, and related infrastructure. This wastewater system is the backbone of our wastewater infrastructure. The system was originally built in 1997 by Dona Ana County, then in July 2017 the system was transferred to Dona Ana MDWCA. Wastewater from the Village of Dona Ana collection system reaches the Dona Ana Lift Station via a series of gravity sewer lines. The wastewater collects in an 8-ft diameter by 24-ft deep wet well. When the well fills to certain depths, the lift station activates and pumps the accumulated wastewater through the force main alignment approximately 3.3 miles southeast.

The lift station has extensive levels of corrosion and deterioration as well as problems with overall functionality. The existing polyvinyl chloride “T-Lock” style liner has separated at several seams leaving the concrete wall of the 8-ft diameter wet well exposed to a corrosive environment. Additionally, the concrete ceiling of the wet well does not currently have any protective covering. Electric conduits routed though the wet well show signs of extensive corrosion. The existing electrical junction box located between the wet well and valve pit is weathered and unsafe. Pump number #1, while functional, rests tilted in position at the bottom of the wet well. 

The existing 8-inch ductile iron force main has failed in a number of locations requiring the replacement of several sections of pipe. The profile of the force main is such that there is a high point located at the southern most end of Cristo Rey Street as the line exits the Village. There is an air & vacuum release valve installed at this point. Following the end of a pumping cycle, the section of force main between the lift station and high point should remain full. The remaining 11,600 feet of force main slowly or partially drains into the discharge manhole located at the north side of Los Venados Subdivision. The resulting partially full line has likely been attacked by the formation of sulfuric acid which has been deteriorated the existing ductile iron force main.
