Fresh groundwater withdrawal restrictions are forcing many coastal Florida utilities and municipalities to develop brackish water supplies to satisfy increased demand. Because of its coastal location and climate, Bonita Springs, Florida is a popular permanent destination as well as a temporary destination for "snowbirds" from January to April. The demand for potable water in Bonita Springs is expected to increase significantly over the next 20 years. In an effort to accommodate population growth and seasonal demands as well as meet South Florida Water Management District's goal of using alternative water sources, Bonita Springs Utilities (BSU) has begun efforts to develop local brackish groundwater sources. A new 6-mgd reverse osmosis (RO) water treatment facility is currently being constructed adjacent to BSU's existing 9-mgd lime softening water treatment facility. By developing water from the Floridan aquifer, BSU will be able to satisfy the growing regional water demands without increasing production from shallower, more sensitive freshwater aquifers. The implementation of this project using a design/build alternative delivery method will allow Bonita Springs Utilities to save capital costs and meet the 2004 demand for potable water.
