Results and Accomplishments
Total investment to date is estimated at $4.4 million dollars. Completed features of the project are wetland mitigation, irrigation distribution system with a 100,000 gallon regulating reservoir with a large channel and sediment basin, and the water control structure. Of the remaining three waterways construction has begun on two with about 95% completion.
Completion of Waterways A, B, and C, will collect and transfer runoff and reduce flooding of agricultural lands and public roads. Excess rainy season intercepted water will be directed through previously built channels to a sediment basin and beyond that to discharge in the
Pacific Ocean. The plan has diversion features that allow collected fresh water to be directed to a planned 70 million gallon reservoir which is to be built in an abandoned quarry area.
Final features of the project consist of a 70 million gallon reservoir, a sediment basin immediately upstream of the reservoir, a pumping plant at the reservoir and a transfer line from the reservoir to a previously built 100,000 gallon tank. These irrigation related features are to be funded equally by the local sponsors and NRCS.
Project completion will benefit the community by:
1. Increasing the island’s self-sufficiency for vegetable crops which are otherwise imported by either air freight or refrigerated container from a minimum of 1,500 miles away.
2. Reducing flooding of agricultural land.
3. Reducing agricultural demands for water from limited sole source aquifer.
4. Reducing flooding of the main road from the island’s east side population center.
