Priority Cesspools in Wahikuli Houselots Subdivision
Community Quote Neighborhood Workshop
The enhancement of existing wastewater infrastructure in Lahaina following the August 2023 wildfires, as well as the U.S. Environmental Protection Agency (EPA) Technical Assistance, will provide for more sustainable wastewater management and enhance resident quality of life, promote sustainable economic development, and reduce economic burden on residents returning to their homes.
This project will make enhancements to the existing wastewater infrastructure in Lahaina, including planning, design and construction of a proposed gravity sewer system to service approximately 231 households, currently serviced by cesspools. The EPA is providing direct technical assistance to support the County, including the County Department of Environmental Management, Department of Public Works and others, as needed, by developing documents necessary for construction. The intent of this technical assistance is to deliver the project “shovel-ready” to the County for construction implementation. The EPA’s Technical Assistance period of performance is approximately 18 months from contract award date.
Lack of funding for construction at the time of writing, compliance with State and federal cross cutters, and applicable County regulations are current roadblocks to implementation of this project. Additional efforts will be needed to incorporate the EPA’s sewer project into a parallel U.S. Army Corps of Engineers (USACE) project in the same vicinity, making sure the designs are prepared in collaboration and navigating the rebuild at the same time as the County is asking for EPA to assist with retainment of easements.
