Broward County and SFWMD have been pursuing development of a County-wide water resources plan since the early 1990’s. This project represents the culmination of efforts by Broward County to develop a County-wide water resources plan and will reconfigure existing modeling tools to develop an IWRMMP. A variety of water management alternatives will be evaluated in the IWRMMP, including reuse of treated wastewater and other alternative water supply sources, such as the Floridian Aquifer system (FAS).

The development of an integrated surface water and groundwater model for the central part of Broward County using MIKE SHE and MIKE11 software was intiated in 2000 and completed in 2002. The model was initially applied to five water management alternatives.

A MIKE SHE/MIKE 11 model of the south part of the County was begun in 2003 and completed in 2005. This model was used to examine water management alternatives that have been proposed to reduce flooding in the C-11 West Basin.

Also, in 2005, the County replaced the North Aquifer Drainage Assessment (NADA) model (using XPSWMM/MODFLOW) by a MIKE SHE/MIKE11 dynamically coupled model. Afterwards, Broward County combined and improved the three MIKE SHE/MIKE 11 models (northern, central, and southern) to provide a seamless integrated surface water and groundwater model (consolidated Broward County model – CBCM) for all of the urban area of Broward County.

Currently DHI is working with Broward County to reconfigure the CBCM model and the SFWMD FAS as part of the IWRMMP to evaluate the cumulative effect of a number of alternative surface and groundwater supply projects intended to meet projected 2025 demand in Broward County. Alternative groundwater supply projects for the Biscayne aquifer and FAS will be evaluated. Alternative water use projects that may be evaluated with MIKE SHE/MIKE11 include reuse of treated wastewater, use of Regional System water made available by the C-51 Reservoir project in Palm Beach County, and aquifer storage and recovery of advanced wastewater treatment. Some of the alternative water use projects that may be evaluated with FAS model include brackish water reverse osmosis of FAS water and aquifer storage and recovery of highly treated surface water or wastewater.
