The North American Development Bank (NADBank) is providing US$250,000 in grant funding for emergency repairs of the Delta Street Sewer Pump Station in the City of Calipatria, a small community located in Imperial County, California. It is the only lift station that serves the city sewer system and receives the entire volume of wastewater collected throughout the community. Once rehabilitated, the pump station will ensure approximately 700,000 gallons per day of wastewater is safely conveyed from the city sewer system to its treatment plant.
NADBank allocated the emergency grant funding for Calipatria because during the final weeks of 2023, the pump station unexpectedly failed, causing raw sewage to flood the dry well and disrupt wastewater flows to the treatment plant. The station was constructed in 1977 and operates continuously—24 hours a day, 365 days a year—to convey wastewater flows to the Calipatria Wastewater Treatment Plant located southeast of the city.

“NADBank is now proactively able to assist communities in emergency situations, while improving environmental conditions,” said NADBank Managing Director John Beckham. He added, “this grant for the community of Calipatria to address the Delta Street pump station failure is the first emergency funding awarded by the Bank.”
The project, with a total cost of US$370,000, consists of replacing all three centrifugal sewer pumps, the rehabilitation of the dry well, the installation of new valves, and replacement of pipelines, as well as minor electrical work. Rehabilitating the Delta Street Pump Station will reduce human health risks by eliminating the possibility of wastewater backing up into homes or overflowing onto streets.
