• All of the operations required for a pump station can remain on-site of the existing facility and does not require additional monitoring of another remote facility. • Allows transfer of additional capacity of up to 1 . 0 rrgd additional beyond what the MasterPlan called for from the South WWTP to the West WWTP . Direction to proceed with survey from the LS#89 site up to 4th Street along the eastern side of the water plant site property boundary was initiated . However, with construction of a new 12" force main on the WTP site to serve the new developments North of the South RO WTP along 12th Street, limited space again' was available in this corridor (east property edge of WTP) for another larger force main. Additionally, IRCU staff preferred an alternate route off-site of the water treatment plant. Upon further review of the 4th Street corridor and in consideration of tie-ing in to LS #89, an alternate corridor off-site of the water plant up to and along the Indian River Farms South Relief Canal west to 58th Avenue is the preferred final routing. The advantage of this route is reduced construction costs, minimized conflicts on the WTP site, and the potential for a reduced construction duration. Written confirmation from Indian River Farms Water Control District (IRFWCD) to occupy this right-of-way shall be requested prior to proceeding with final survey and design . In conclusion, completion of a West wastewater transmission system described above includes four proposed sections of piping. The first section is currently under design by another consulting firm on 82nd Avenue from 4th Street to 8th Street, which connects to an existing 24- inch force main that extends to the West WWTP . The second is a section of pipe being included in this project by this Work Order # 12 . This second pipe is along 8th Street from 82 ad Avenue to 74th Avenue and connects on 82 ad Avenue mentioned previously to the pipe originally associated with Work Order # 10. The third section of pipe is described in the paragraph above, as originally associated with Work Order # 10 and is along 8th Street from 74th Ave to 58th Avenue. The fourth section ofpiphe consists of approximately 3 3/4 miles of force main that connects the pipe at 8th Street and 58t Avenue with the proposed re-pump station adjacent to LS 489 . This fourth section of pipe is the replacement of the section of pipe that was originally planned to be constructed as a result of Work Order #8 . Refer to Exhibit 1 attached depicting the proposed force main route. SCOPE OF SERVICES The Consultant will provide route evaluation, survey, design, permit application preparation, and construction phase services for the new wastewater transmission system. Potential east-west corridors for this pipeline include the South Relief Canal, 12tH 8" 4th and Is' Streets SW. The Consultant will review these alternate routes for the new forcemain to identify those routes with adequate available right-of-way. The Consultant will provide survey services from the LS #89 along the IRFDD corridor as listed herein . The survey from 74th Avenue to 82 ad Avenue will be provided to the Consultant from another firm by IRCU . The consultant shall rely on the accuracy of this information . The design of the forcemain from LS #89 to the intersection of 8th Street and 82 ad Avenue will consist of preparation of project drawings and specifications for the project, which can be advertised for bidding by general contractors . The Consultant will prepare and submit the appropriate permit applications listed herein for the construction of the project. The Consultant will provide construction phase services during construction, and provide final certification of the project.
