Hart St. Wastewater Pump Station Old Force Main Improvements - Phase 1 - Honolulu, Hawaii

Hart St. Wastewater Pump Station Old Force Main Improvements - Phase 1 is a distribution pump station located at 1031 North Nimitz Highway in Honolulu, Hawaii. This facility is part of the wastewater collection system for the Honolulu area, operated under the regulatory oversight of the Hawaii Department of Health and the U.S. Environmental Protection Agency. The pump station is currently operational and plays a key role in conveying wastewater from the collection system to treatment facilities. While specific technical specifications such as flow capacity are not detailed, the facility is part of a broader network of aging infrastructure in Honolulu that has undergone improvements to enhance reliability and reduce overflows. Environmental significance includes reducing the risk of sanitary sewer overflows into nearby waterways, including Honolulu Harbor and the Pacific Ocean. The improvements help protect marine ecosystems and public health by ensuring efficient wastewater transport, especially during heavy rainfall events common in Hawaii's tropical climate.

The pump station is located near Honolulu Harbor, a critical estuarine environment that supports marine life and commercial activities. Aging wastewater infrastructure in coastal areas poses risks of overflows that can degrade water quality and harm coral reefs. The improvements to this force main help mitigate such risks by enhancing system redundancy and capacity, aligning with federal Clean Water Act requirements to prevent unauthorized discharges.
