Sulphur Springs Flow Augmentation Feasibility Study

Professional Engineering Services to develop a feasibility study to investigate routing surface water from Curiosity Creek high flow events, options to store and treat excess storm water, and mechanisms to reduce salinity and improve flow to Sulphur Springs and ultimately the Lower Hillsborough River to be considered as augmentation freshwater sources to assist in meeting the Sulphur Springs Run Minimum Flows established by Southwest Florida Water Management District. The selected firm is expected to perform engineering investigations, groundwater and stormwater modeling, evaluation of alternatives and all related work as part of the feasibility study. Key tasks to be performed are: • refine the SEAWAT model previously developed for another project to understand the benefit of freshwater augmentation to Sulphur Springs. • expand the Hillsborough County’s Curiosity Creek stormwater model to include additional City of Tampa areas. • evaluate storage and pumping including existing and new facilities. • evaluate natural system connectivity (ponds, lakes, Curiosity Creek, sinks, caverns and springs) and perform hydrogeologic field investigation including review of prior studies and investigations • investigate alternatives to accomplish project goals. And provide an Alternatives Analysis Report for this task. Cost information shall be included. • investigate sources causing clogging of sinks and caverns and removal solution development. The project is expected to be performed over multiple years with an overall $640,000 for the feasibility study.
