Port St. Lucie is advancing plans for a new water treatment plant as the city responds to rapid population growth and increasing water demand. The new Port St. Lucie water treatment plant is expected to play a central role in supporting the city’s expanding infrastructure and safeguarding its water resources.
Port St. Lucie Water Treatment Plant to Address Population Surge
The City of Port St. Lucie has surpassed 250,000 residents, with projections indicating a rise to 350,000 at full build-out. City officials report that this growth is driving the urgent need for expanded water infrastructure, including the construction of a fourth water treatment facility.
According to city planning documents, the estimated cost for the new water treatment plant is $80 million. The facility is scheduled to be operational by 2030, a timeline accelerated to meet the city’s evolving needs.
Location and Strategic Importance of the New Facility
The new Port St. Lucie water treatment plant will be located near Range Line Road, close to recent large-scale residential developments and the McCarty Ranch Water Quality Project. This location was selected to maximize efficiency and support both current and future water supply demands.
City officials indicate that proximity to the McCarty Ranch Preserve and Extension properties is critical. These areas were acquired to secure future water resources, leveraging large lakes and access to the C-23 Canal for water storage and supply.
Integration with McCarty Ranch Water Quality Project
The McCarty Ranch Water Quality Project is a cornerstone of Port St. Lucie’s water management strategy. The project involves converting over 1,800 acres of former citrus groves into shallow water reservoirs. These reservoirs capture stormwater, reduce nutrient pollution, and recharge local aquifers.
According to city reports, this initiative helps reduce the volume of freshwater discharges into the St. Lucie River and Indian River Lagoon, supporting both water quality and regional ecosystem health.
Broader Water Management Strategy in Port St. Lucie
Port St. Lucie’s water management approach includes one of the nation’s largest septic-to-sewer conversion programs. City data shows that over 10,000 aging septic tanks have been removed, and the installation of nearly 33,000 new ones has been prevented. This program is designed to protect groundwater and public health.
Additional investments include the $36 million Eastern Watershed Improvement Project and ongoing efforts to reduce nutrient loads in local waterways. These projects are part of a coordinated response to environmental challenges associated with urban growth.
St. Lucie River Watershed Protection Plan
Regional water management is also shaped by the St. Lucie River Watershed Protection Plan. This plan aims to reduce nutrient pollution, improve water quality, and balance flood control with the protection of sensitive ecosystems.
Officials report that these efforts are coordinated across multiple agencies to ensure effective outcomes for both residents and the environment.
Environmental and Community Benefits
Experts in water resource management view the new Port St. Lucie water treatment plant as a critical step for long-term water security. The facility is expected to support sustainable growth while helping to protect sensitive ecosystems from the impacts of urbanization and climate variability.
City officials highlight that the project is part of a broader, multi-agency approach that integrates infrastructure expansion with environmental restoration and public engagement. This comprehensive strategy is considered a model for other rapidly growing communities facing similar water supply and quality challenges.
