Water and Wastewater Infrastructure Assessment Findings The Traffic Analysis Zone (TAZ) data and future land use data provided by Hillsborough County for the Palm River redevelopment area shows a 9,978 person increase in population from 2015 to 2045. The estimated increase in potable water demand is 2.99 MGD and the estimated increase in wastewater generation is 2.00 MGD. The South-Central water system has 19.7 MGD of available permit capacity and the David L. Tippin WTP has 39 MGD of available capacity showing adequate production capacity to serve the 2.99 MGD increase in water demand. The Hillsborough County Falkenburg AWWTP has 1.8 MGD of available permit capacity and the City of Tampa Howard F. Curren AWWTP has 36 MGD of available permit capacity. If the majority of the increased wastewater flow is to be routed to Hillsborough County, there may be a treatment capacity issue at the Falkenburg AWWTP to serve the anticipated growth. If no wastewater treatment plant expansions are planned by Hillsborough County at the Falkenburg AWWTP, wastewater would need to be diverted to the City of Tampa or to the Hillsborough County Valrico AWWTP so that the Falkenburg AWWTP does not exceed its available permit capacity. The Hillsborough County Valrico AWWTP has a permitted capacity of 12 MGD, with an annual average flow of 7.25 MGD and a maximum hourly flow of 7.93 MGD. This provides an additional 4.07 MGD wastewater treatment plant permitted capacity for new development or redevelopment. This capacity analysis is based only on the available permitted capacities of the water and wastewater treatment facilities; no hydraulic capacity analysis of water/sewer transmission mains was completed. Based on the water and wastewater infrastructure assessment completed for the Palm River Redevelopment Area, potable water is available to all redevelopment project sites identified in Figure 5 of the report. Sewer collection is available for all redevelopment project sites except the two projects located along Hartford Street, which have septic systems. Further evaluation of the City’s and County’s water, sewer, and septic systems need to be studied prior to redevelopment. The following action items have been identified for the Palm River Redevelopment area: • Coordination between the County and City of Tampa utility departments to identify capacity issues in the potable water and sewer collection/ transmission systems • Study existing potable water hydraulic model to determine pipe capacity and sizing needs of future developments with new water demands • Study existing wastewater collection, transmission, and wastewater treatment plant capacity to determine if the increased wastewater flow will affect the system • Extend sewer collection/transmission system to the redevelopment projects on Hartford Street to eliminate the septic sewer system • Provide water and sewer service connection along street areas that are not currently served to promote redevelopment: • Hartford Street, 36th Avenue, 70th Street, 78th Street, and US 41/50th street areas were identified as areas the County will need to coordinate sewer collection/transmission system extensions to eliminate septic to sewer systems • 36th Street and 70th Street areas were identified as areas that the County will need to coordinate transmission main extensions Water and Wastewater Infrastructure Assessment Findings
