SCOPE OF SERVICES Task 1—Wellfield Expansion and New Wellfield Evaluation Consultant will evaluate potential expansion of existing Hobart and Oslo UFA wellfield(s)to include new UFA wells,wellheads,piping, and pumping stations as required as long as this expansion does not impact ELU's. Consultant will evaluate feasibility of a third UFA wellfield for the Hobart WTP and/or expansion of the existing Oslo WTP wellfield. Consultant will also evaluate the need to potentially site a third/western wellfield and potential separate third WTP if that is the only option for use from an ELU standpoint if the wellfield expansion or deepening at the existing WTP's is not feasible. Consultant will prepare conceptual costs and timelines for this option if needed to be included in the evaluation matrix. Consultant will evaluate potential well sites and raw water supply based on the following: • IRC owned land • ELU impacts • Potential large landowners and developments • Accessibility for drilling, formation water disposal • Power supply availability • Setback requirements (sanitary, surface waters, contaminants) • Raw watermain routing& looping potential • Conceptual sizing of well, well pumps, electrical Consultant will prepare GIS maps that delineate countywide ELUs, respective capacities, and aquifer from which water is withdrawn. The GIS data will be queried to delineate type and capacity of each use, and potential impact from IRCU wells in the vicinity of the ELU's. The GIS information will also be used to overlay existing IRC owned land, zoning maps,rights-of-ways, and setbacks for new wells(i.e.,contaminated sites, sanitary setbacks,etc.). It is assumed that IRCU staff can provide some of this GIS information. Consultant will prepare conceptual costs for new wells,wellheads and pumps,raw watermain,booster pumping stations. Site costs will not be included,but if IRC owned sites are selected,they will be assumed to be negligible. Consultant will prepare a map of proposed wellsites, and conceptual piping arrangement and alignment to supply raw water to both Hobart WTP and Oslo WTP. Multiple maps may be used to depict multiple layers of information. Up to six(6)different map types may be provided in both electronic and hard copy format(24 x 36 size). Task 2—Test Well Evaluation of LFA and APPZ @ Oslo and Hobart Consultant will investigate the potential use of the Avon Park Permeable Zone (APPZ) which his part of the lower Upper Floridan Aquifer(UFA),and the Lower Floridan F:\Utilities\UTILITY-Engineering\WATER\CUP-10524\Admin\KHA\2021.5.1-FINAL AWS Eval Scope fh MDM_vb.docx Page 2 of 11
