This project includes two separable elements. The C-51 Regional Groundwater Aquifer Storage and Recovery (ASR) system and L-8 Basin ASR system. These projects will provide additional long-term storage within the North Palm Beach County region.

a) C-51 Regional Groundwater Aquifer Storage and Recovery (LL).
This project includes a series of ASR wells with a total capacity of 170 million gallons per day, associated pre- and post- water quality treatment to be constructed along the C-51 Canal, and canals that can receive water from the C-51 Canal. The conceptual design assumes 34 well clusters, each with an individual capacity of 5 million gallons per day fed by a combination of vertical and horizontal wells located near existing canals. The conceptual design includes disinfection pre-treatment and post storage aeration. The level and extent of treatment and number of the ASR wells may be modified based on findings from a proposed ASR pilot project.

The purpose of this project is to capture and store excess flows from the C-51 Canal, currently discharged to the Lake Worth Lagoon, for later use during dry periods. The ASR facilities will be used to inject and store surficial aquifer ground water adjacent to the C-51 Canal into the upper Floridan Aquifer instead of discharging the canal water to tide. Water will be returned to the C-51 Canal to help maintain canal stages during the dry-season. If water is not available in the ASR system, existing rules for water delivery to this region will be applied.

b) L-8 Basin ASR (K - Part 2).
This separable element includes ASR wells with a total capacity of 50 million gallons per day and associated pre- and post- water quality treatment to be constructed within the L-8 Basin or along the City of West Palm Beach water supply conveyance and storage system or a combination of both. The conceptual design consists of 10 wells, each with an individual capacity of 5 million gallons per day for a total capacity of 50 million gallons per day. The conceptual design includes disinfection pre-treatment and post storage aeration. The level and extent of treatment and number of the ASR wells may be modified based on findings from a proposed ASR pilot project.

The purpose of this project is to increase water supply availability and moderate water level within the West Palm Beach Water Catchment Area. It will also provide flows to enhance hydroperiods in the Loxahatchee Slough; increase base flows to the Northwest Fork of the Loxahatchee River, and reduces high discharges to the Lake Worth Lagoon. During periods when the West Palm Beach Water Catchment Area is above desirable stages, 50 million gallons per day will be diverted for storage in the ASR wells.
