09 / 24 / 04 FRI 10 : 41 FAX 15818417819 KHA FIRKWIDE 14002 k Attachment 1. Pniect Description and Understtuadint Construction of a new master pump station is slated under Indian River County Utilities (IRCU) CIP project it WW012 which will act as a repump station directing wastewater flow to the North Regional WWTP. This pump station would allow redirection of current flows from the Chesser Gap pump station east along CR510 to the NR WWTP. Additionally, in anticipation of future flows from Fellsmere, this pump station should be sized accordingly 1.0 accept City of Fellsmere flows and future development estimated to be approximately 6800 ERU' :; The project will include cutting into the existing forcemain along CR 510 and direoting flows to the new pump station to be located at the and of 64 " Avenue on the Douglas school property. The pump station discharge would be redirected to the CR 510 forcemain allowing pumping to the NR WWTP. The school is offering the site up for use in anticipation of abandoning their drainfield and extending gravity sewer to the pump station. The design of the pump station should consider this tie-in. Normal anticipated flows for the pump station are expected to range from 1000 span to 2000 gpm with initial flows being much less. The design of the station should consider either the use of VFD' s to account for the wide range of flows or an allowance for a triplex (three pumps) station with initial construction to only include a duplex (two pumps) station. Modeling scenarios, using IRCU 's existing sewer systema hydraulic model will be evaluated to identify the ideal recommended option . The station should also include odor control facilities similar to the systerns 1RCU currently operates. A Biocube type system should be designed to handle odors from the pump station. The station should also include backup auxiliary power using dim: l driven generator with an automatic transfer switch. Radio telemetry will be included for remote monitoring and control and match IRCU's standard. It is assumed that Data Flow system will be specified . SCOPE OF SERVICES Consultant will provide survey of the site and 64's Avenue for the construction ofnew forcetnain and pump station. Consultant will prepare project drawings and specifications for the project which can be advertised for bidding by general contractus. Consultant will prepare and submit the appropriate permits listed herein for the construction of the project. Consultant will provide construction phase services during construction, witnessing startup and operational testing, and provide final certification of the facility. The scope includes the following: Task .1 — Survey KHA will provide survey of the site and 64'b Avenue where the master pump station will be located and for the influent and effluent piping located along 60 Avenue up to CR 510. The site survey will include a boundary survey for easement transfer with the adjacent school (Douglas Magnet County school ) which will also include at least a 100 'x 1. 00' area., topo, and other above ground information. Itis anticipated that the site granted to Utilities will be approximately 50 ' x50 ' . For the forcemain piping along 640' Avenue, approximately 600 ' of survey incl uding centerline baseline with 50 ' offsets, 50 ' topo with 100 ' stationing, edge of pavement, existing utilities, and benchmarks (2) will be included. Right of way information will be included in the survey . It is assumed that Utilities will provide locates of their existing lines at the intersection and along (4s Avenue. Task 2 ,, Design The design will include hydraulic evaluation , pump station design, pipe sizing, preparation of drawings
