This project will update the capacity of water infrastructure in Lahaina by improving pipeline and facility deficiencies to meet current hydraulic criteria to address low fire flow residual pressures in the water system. The County’s Department of Water Supply identified the most critical capacity deficiencies in the water system to be insufficient storage and undersized waterlines. Priority projects to mitigate deficiencies include:

1. Construction of a new 1.7-million-gallon water storage tank to increase Lahaina’s water system’s storage from 4.4 million gallons to 6.1 million gallons
2. Small diameter pipeline upgrades to correct hydraulic deficiencies and improve fire flow
3. North-South Transmission Main upgrades to improve the conveyance of water from North of the Lahaina system to South of the system

This project addresses the infrastructure upgrades necessary to meet capacity needs, but water source development is also a critical component of addressing capacity deficiencies. This will require collaboration with CWRM to secure the necessary water use permit allocations to accommodate new water source development in West Maui.
