Integrated Regional Water Supply Plan
The Peace River/Manasota Regional Water Supply Authority supports a growing west central Florida customer base with water treatment, storage, delivery and related facilities. As an independent special district of the state of Florida, the Authority strives to ensure adequate water supply within its four-county service area while preserving and protecting the environment.
Peace River, or Rio de la Paz, was named by a Spanish cartographer in the 1500s. In the following centuries, significant events and trends—the Seminole Wars of the 1800s, phosphate mining and a century of intense development—led to substantial changes within the Peace River watershed.
To ensure the watershed is protected and increasing customer requirements are met, HDR was contracted by the Authority to develop an integrated regional water supply master plan. The master plan evaluated existing and projected regional water supply, as well as demand conditions. The plan also evaluated the development of existing and proposed surface water and groundwater supply sources to meet these projected conditions.
An important element of master plan was the development of a model-based reliability tool, the Regional System Reliability Model (RSRM), which allowed the Authority to evaluate how multiple water supply scenarios could meet future demands in the most cost effective and environmentally responsible manner.
The RSRM was developed using STELLA® modeling software. Additionally, the RSRM was created as an open source model, allowing the Authority and its authorized users to access and modify RSRM programming to accommodate model modifications as potential water supply sources change.
With the demand for water from the Authority expected to increase from about 18 million gallons per day (mgd) to 80 mgd by 2025, the RSRM and master plan developed by HDR will help guide the Authority in developing water supply projects to meet these projected regional water demands.
The master plan outlines a seven-year capital improvement program, evaluates water supply sources through 2024 and presents a long-term vision of regional water supply trends and needs through 2050.
