Background
The city of Holtville is located in Imperial Valley, approximately 11 miles east of El Centro, CA. In 2012, wastewater collection coverage was estimated at more than 98% through 1,369 sewer residential and commercial connections. All of the collected wastewater is treated at the city’s wastewater plant, which has a treatment capacity of 0.85 million gallon a day (mgd).
The City was looking to expand its wastewater collection system to 23 homes within two neighborhood blocks to replace failing on-site septic systems and eliminate wastewater overflows reported in the project area.
Project Scope
The main components of the project included the construction of two 600-foot, 8-inch PVC sewer lines, installation of 23 residential connections and the abandonment of the septic systems in the area.
Benefits
The project is reducing the potential for groundwater and surface water contamination from sewage spills and leaks, thus providing a cleaner healthier environment for local residents. It provided first-time sewer service to 23 households, collecting an estimated 8,100 gallons a day of wastewater for treatment.
