City of Plant City Reclaimed Water Main Sanitary Sewage Force Main and Potable Water Main Improvements

Jones Edmunds provided the detailed design, prepared contract documents, obtained permitting, and provided limited construction-phase services for installing a Reclaimed Water Transmission Main (RCWM) and a Sanitary Sewage Force Main from the City’s wastewater treatment plant on Victoria Street to Cherry Street. The project involved preparing construction plans and specifications for two large-diameter parallel pipelines, along with roadway improvements, selected potable water main replacements, and future RCWM connection stub-outs. Specifically, the RCWM provided a source of reclaimed water from an existing RCW high-service pump station discharge pipe at the treatment plant to Wilder Road. Jones Edmunds’ services included:
  • 16,600 feet of 24-inch reclaimed water main
  • 12,600 feet of 20-inch sewage force main
  • 2,000 feet of 12-inch potable water main
  • FDOT permitting
  • Roadway reconstruction of over 4,000 feet of Cherry Street
  • CSX railroad permitting
  • Stakeholder communication and involvement
The job included furnishing and installing the new pipe, valves, fittings, connections, and crossings; excavating, backfilling, and compacting; testing; re-paving; and disposal and restoration in accordance with the project plans and City of Plant City specifications. The pipelines were installed along rights-of-way and in most locations required restoring the entire roadway to the original grade and dimensions. In some areas minor roadway and drainage flow improvements were accomplished as part of revised restoration activities. Jones Edmunds was also responsible for project permits, including a crossing of active CSX railroad lines and required permits, including SWFWMD, Hillsborough County Health Department, and FDEP. We also coordinated with and installed pipeline in conjunction with an ongoing FDOT roadway-widening project, requiring FDOT permitting. The route of the pipelines mainly traversed residential and commercial areas, which required close communication with the public. Pipeline tie-ins required close coordination with Hillsborough County Community College at one terminus and the City of Plant City’s wastewater treatment plant at the origin of the project.

Pinellas County North County Phase 2B Reclaimed Water Distribution System

Jones Edmunds conducted the routing study, prepared the detailed design, and obtained permitting for 135,000 feet of transmission and distribution mains ranging from 4-inch to 16-inch diameters. Notably, the transmission and distribution mains provide reclaimed water service to over 2,200 properties, including 6,400 feet of 16-inch-diameter transmission main installed by open cut and horizontal directional drilling. The design was prepared in accordance with Pinellas County Utilities standards. Jones Edmunds prepared the plans, specifications, and permit applications in three separate bidding parts, including hydraulic modeling of the total Phase 2B and adjacent systems. In addition, coordinating with other consulting engineers (under separate contract with the County) was required on adjacent tie-in locations. Furthermore, Jones Edmunds participated in public meetings with local concerned citizens. We also performed limited construction-phase services, including reviewing shop drawings and assisting the County as needed during construction and system start-up. Jones Edmunds’ services included:
  • Design of a 6.400 feet of 16-inch diameter transmission main installed by open cut and horizontal directional drilling
  • Design of 135,000 feet of transmission and distribution mains ranging from 4-inch to 16-inch diameters
  • Coordinating with FDOT for crossings and right-of-way
  • Utility locates/pipe routing
  • Ensuring maintenance of traffic
  • Obtaining permitting
  • Interfacing with consultants
  • Designing adjacent phases
This project required coordination with multiple consultants chosen by the County on tie-in locations. Specifically, this required designing to alleviate unacceptable pressures remaining from other portions of the project.

City of Plant City Sydney Road Reclaimed Water Main

Jones Edmunds designed and obtained permitting for a reclaimed water main and booster pump station to connect the City’s WRF to two private reclaimed water customers along the route and three service points to the Walden Lakes Community golf course. The reclaimed water main installation includes:
  • A booster pump station
  • Two pond discharge stations
  • Two pond-level monitoring stations
  • Approximately 23,000 feet of 24-inch PVC transmission main
  • 6-inch, 8-inch, and 12-inch PVC distribution mains
The reclaimed water main design includes:
  • Two FDOT roadway crossings
  • Two CSX track crossings
  • Work in several City streets
The design for the pipeline includes several construction methods including:
  • Jack and bore under the two CSX tracks
  • Jack and bore under two highway crossings and one culvert
  • Open cut and HDD in the other areas of the project
Permitting issues had significant impact on the overall project. Wetlands along the route required an ERP permit from SWFWMD and an EPC permit from Hillsborough County. City personnel are performing the construction and therefore preparation of formal contract bid documents was not required. However, Jones Edmunds provided sewer plans and technical specifications. The work is partially funded by grants from SWFWMD and FDEP.

City of Largo Water Reclamation Facility Analysis & Recommended Upgrades

Jones Edmunds was part of a comprehensive team that evaluated the City of Largo’s sanitary sewer and wastewater treatment and disposal systems for capacity assessment and improvements. Jones Edmunds was responsible for the hydraulic and treatment capacity assessment of the City’s 18-MGD-AADF advanced biological nutrient removal wastewater reclamation facility (WRF). The project goals were to identify hydraulic improvements and treatment alternatives to reliably meet current and future hydraulic and biological treatment capacity needs for the current and expected future regulatory requirements. This evaluation was conducted through a combination of flow monitoring, physical survey, hydraulic assessment, and unit process assessment, including substantial efforts in biological system modeling and capacity assessments using customized and calibrated BioWin models. Jones Edmunds configured and calibrated the BioWin BNR modeling to simulate the performance of the existing biological nutrient removal processes and to evaluate several process configurations/modifications for biological nutrient removal improvements at future flows and loading conditions.In addition, Jones Edmunds implemented a full-scale clarifier stress testing program and computational fluid modeling to determine the ability of the secondary clarifiers to handle projected peak-hour flows and solids loadings. We configured a state-of-the-art clarifier computational fluid model (CFD) using the 2Dc CFD model developed by Dr. Alex McCorqudale at the University of New Orleans. Although the clarifiers did not meet 10 States Standards criteria for peak-flow conditions, field testing and modeling demonstrated that the clarifiers will handle the expected peak flows. Jones Edmunds evaluated the overall hydraulic performance of the chlorine contact basins at the plant by conducting a fluorometric dye study. This study determined the effective detention time achieved in the basin compared to theoretical detention time calculations and identified potential ways to optimize plug-flow dynamics.

City of Clearwater Headworks Evaluation, Design, and Construction-East, Northeast, and Marshall Street Water Reclamation Facilities

Jones Edmunds conducted a Headworks Evaluation and Design for the City’s three water reclamation facilities (WRFs) – the East, Northeast, and Marshall Street WRFs. We also provided a scope for construction-administration-phase services for the Headworks Improvements. Services included evaluating system flows, assessing removal efficiencies of the grit system compared with the system’s basis of design, conducting onsite grit sampling and characterization, and evaluating new mechanical fine-screening and dewatering equipment. The recommended grit removal (vortex) and fine-screenings design upgrades (washing, dewatering, and compacting) for each WRF will increase capture efficiency of screenings and grit and reduce operations and maintenance (O&M) costs associated with repairing and cleaning basins. Electrical and control modifications were also performed on the new headworks systems.
