Key Haven Lift Stations & Force Main Transmission System
The Florida Keys Aqueduct Authority contracted with Baxter & Woodman (Mathews Consulting) to prepare construction documents for the Key Haven community (located at MM 5.2) utility upgrades. Baxter & Woodman previously designed a new sanitary collection system for Key Haven as part of a separate project, “Key Haven Utility Improvements.” Upon construction of the new sanitary collection system, the existing transmission system, which included a total of five lift stations, was no longer useable in its current configuration.
The project included the following components:
- Design of three new District Lift Stations
- Specific upgrades to two existing lift stations (District A Lift Station and Plant Lift Station) which were re-used
- 8-inch force main transmission system
The lift station design criteria was based on the flow from all District Lift Stations as well as the Plant Lift Station being discharged directly to the equalization tanks at the Boca Chica WWTP via a new 8-inch force main. The new force main transmission system consists of an 8-inch pipe from Key Haven Road, east along US 1 (Overseas Highway), across the Boca Chica Bridge and ending at the Equalization Tanks at the Boca Chica Waste Water Treatment Plant.
