Town of Peralta Wastewater Project Receives National Award


The US Environmental Protection Agency (EPA) recently recognized the Town of Peralta for their $3 million Regional Sanitary Sewer Project funded through the Clean Water State Revolving Fund (CWSRF) program. The project was selected as part of the Performance and Innovation in the SRF Creating Environmental Success (PISCES) program which recognized exceptional projects funded by the CWSRF at the national level. Molzen Corbin has assisted the Town with their sewer system from the beginning with master planning, funding assistance, previous phases of design/construction, and served as the lead engineering firm for this project, responsible for the design and construction oversight. This project was financed with a $3 million CWSRF grant/loan administered by the New Mexico Environment Department – Construction Programs.

The Town of Peralta had no wastewater collection or treatment system, and individual homes were using aging septic systems that were not properly maintained. Many shallow domestic wells were densely located among these septic systems, which created a risk of drinking water contamination. A traditional gravity sewer collection system with lift stations was cost prohibitive due to the shallow groundwater depth and narrow rights-of-way, so the new regional sanitary sewer collection system utilizes a low-pressure grinder pump system. This low-pressure system includes two-inch to eight-inch diameter collection lines which are installed at a depth of three to four feet below finished grade.

Peralta entered into a Memorandum of Understanding with the neighboring Village of Bosque Farms to allow Peralta to connect to their sewer system and wastewater treatment plant (WWTP), as Bosque Farms had the capacity to treat additional flow. This intermunicipal agreement demonstrates regional planning to address significant public health concerns for local residents. Molzen Corbin played a critical role in advancing the agreement as it serves as the on-call engineer for both municipalities.

Molzen Corbin Awarded 2020 Engineering Excellence Award for Belen Fire Station

On January 22, 2020, the American Council of Engineering Companies – New Mexico (ACEC-NM) announced that Molzen Corbin was awarded the 2020 Environmental Engineering Excellence Award for the Belen Fire Station. Molzen Corbin was proud to serve the City of Belen as the lead architectural and engineering firm on this project, ensuring the shared goal to have a state-of-the-art fire station nestled in the heart of downtown.

While the downtown site was ideal for the City, it presented several unique challenges to the Molzen Corbin design team. The two initial issues the team encountered were that the site was small with limited access and that it was located within a flood plain. However, the most critical challenge faced by the team was that contaminated soil was discovered during the soil investigation phase of the project.

Molzen Corbin answered these challenges with innovative, cost-effective solutions. The team designed a 13,000 square-foot facility that used every square inch and public access available on the site to provide a functional facility with easy maneuverability. Our design elevated the finish floor above the flood line to protect the facility, allowing it to remain operational, even if the surrounding low-lying area floods. Finally, we worked contaminated soil remediation into the budget and schedule, and integrated an innovative below slab ventilation system to eliminate the possibility of contaminated fumes infiltrating the facility.

Mr. John Pate, Vice President of Architecture, summarized the project: “I am proud that we brought efficiency and economy to the project by capitalizing on one deficiency to mitigate another. We minimized earthwork by elevating the building above the floodplain, reducing the amount of contaminated soil to be removed and disposed of. Even with the challenges presented, we were able to design a facility that met the needs of the community and delivered the project on time and within budget.”

Since the ribbon cutting Grand Opening Ceremony in October of 2018, the fire station has been occupied continuously (24/7). Its layout ensures that internal response time (time for firefighters to reach apparatus and be prepared to depart) is minimized and functionality is maximized within a comfortable and healthy environment. Equipped with state-of-the art, high-speed folding doors, the five 60-foot deep apparatus bays house firefighting and emergency-response vehicles. The station also includes administrative and training areas, support areas (where vehicles and firefighting equipment can be cleaned and stored), and residential areas (including dorms, dayroom/kitchen, fitness room, outdoor activity area, and bathrooms).

City of Las Cruces Interstate 25/University Project Ribbon Cutting Ceremony

The NMDOT, City of Las Cruces and NMSU recently celebrated a groundbreaking for the long awaited I-25/University Avenue interchange project.  Molzen Corbin, with an office in Las Cruces, is proud to have been selected by the NMDOT to design the upcoming capacity improvements.

The $33.3 million, six-phase project is set to begin construction on January 2, 2020 and last through the Summer of 2021. The project’s objectives are to add capacity at I-25’s southbound off-ramp to NMSU, reduce congestion and weaving, provide direct connections to Pan American Center parking lots, promote sustainability through recycling and use of energy-efficient materials, and build two roundabouts for better flow of local traffic.
