PROJECT SELECTION PROCESS

On November 29, 2022, Henry T. Wingate, United States Federal District Judge in the United States District Court for the Southern District of Mississippi (Northern Division) signed an Interim Stipulated Order in Case No. 3-22-cv-00686-HTW-LGI, the United States of America v the City of Jackson, Mississippi. This order appointed an Interim Third-Party Manager (ITPM) to control the drinking water system in Jackson, serving the residents of Jackson, the town of Byram, and a portion of Hinds County. The Order also included a list of priority projects that were to be completed by the ITPM as expeditiously as possible to ensure safe and reliable drinking water remains available to all customers, at all times. These projects have been programmed with other available funding in the Financial Management Plan developed by the ITPM in January 2023 as updated in April 2024, and those programmed for funding through the State Of Mississippi, Drinking Water Systems Improvements, Revolving Loan Fund Program (DWSRF) in 2024 are included in this appendix. These projects were developed based on knowledge JXN Water is gaining daily, a preliminary CIP developed by Jacobs, preliminary results from Stantec's analysis of the distribution system, and best engineering practices.

PROGRAM ACTIVITIES

Distribution System Optimization

Over the past year a GIS was completed which enabled completion of a hydraulic model. Additionally valve assessment work found and corrected positions of over 1,000 valves. This data formed the foundation for a complete assessment of the distribution system. Several deficiencies were identified with solutions varying from new pipe segments, increased diameter of existing pipes, pressure booster stations, etc. This project will design and construct these solutions.

Small Diameter Pipe Replacement

A significant factor in the challenges to maintain pressure and water quality in the distribution system is the over 100 miles of piping in the Jackson Water System that is less than 6 inches in diameter, with a majority of that 2-inch diameter galvanized pipe. All small diameter piping needs to be replaced with a minimum of 8-inch diameter pipe. This will improve localized pressure issues, meet current fire protection standards, and will improve aesthetic qualities of the water (taste, odor, color) in homes and businesses served by these 2-inch pipes. This program will replace the 2-inch through 4-inch diameter mains as well as service lines back to the edge of the public rights-of-way. The work will be coordinated with funding for wastewater system improvements to allow replacement of sewer lines in the same streets at the same time - preventing streets from being opened twice.

SCADA

This project will install a completely new SCADA system providing data to control and manage the entire water system (plants, wells, and distribution system). A fully functional SCADA is necessary for reliable operation of modern water systems. This project will provide that for JXN Water.

Chemical Feed Repair (OB Curtis)

The chemical feed and disinfection systems and supporting facilities at the O. B. Curtis WTP need to be replaced with safer and more reliable systems. The current systems do not support reliable operation of the WTP process for safe, reliable, and sustainable drinking water. Aluminum chloralhydrate (coagulant), sodium permanganate (oxidizer), coagulant aid polymer, and fluoride system will be replaced with similar processes. The disinfection systems will be transitioned from gas to liquid feeds. The existing chlorine gas system will be replaced with an on-site hypochlorite generation system to feed hypochlorite and the existing ammonia gas system will be replaced with a liquid ammonium sulfate system. Treatment Process Renewals

As part of the third-party operation and maintenance of the water treatment plants, a comprehensive process review was conducted to ascertain process improvements required to maintain safety and reliability. This assessment identified various projects that need to be implemented to address condition, reliability, and capacity constraints. This project will address some of the highest priority items identified during the process review and CIP development including improvements to the flocculation and sedimentation basins, permanent liquid lime system, and residuals handling system.

DWSRF Retirement

To reduce debt service burden on the system, existing DWSRF debt will be retired with this project. Current payoff is approximately $13.9 million.

Water Meter Infrastructure (2021)

This project will purchase the Kamstrup AMI water meters installed under a master utility services agreement (MUSA) with Sustainability Partners. Under the current agreement, JXN Water does not own the meters but pays a monthly service fee for use of the meters. This project will purchase meters, meter boxes, and related infrastructure. The MUSA will be amended to reflect the change of meter ownership which will reduce the monthly costs currently incurred by JXN Water.

Resilient Power Facilities for OB Curtis

This project will add alternative and emergency power facilities to OB Curtis to ensure critical treatment processes can be operated during prolonged failures or disruptions to the Entergy grids serving OBC.

Distribution System Upgrades and Replacements

This project will replace pipe segments identified as highly likely to fail, undersized, or sources of significant water loss as identified by JXN Water's ongoing condition assessment. The project will also replace failed valves, install new valves as necessary, new hydrants, and related water distribution infrastructure throughout the JXN Water system.

OBC Residuals System Upgrade

The residuals system at OBC has failed. Preliminary evaluation indicates it may have significant design issues as well. This project will conduct a complete evaluation of the residuals system and a cost benefit analysis to determine the best life-cycle cost solution for OBC. The solution will be designed and implemented with this project upon completion of the selection of the best cost alternative.

Well System Upgrade

This project will make needed improvements to the groundwater (well) system operated by JXN Water. This system serves nearly 15,000 connections and needs significant improvements to ensure safe and reliable service. An additional well will be installed, new piping, disinfection facilities, rehabilitation of storage facilities, site security and related improvements will be incorporated into this project.

Distribution Storage Upgrades

This project will make needed upgrades and rehabilitations to the storage tanks throughout the JXN Water system. Many of the tanks are in need of repair of structural elements, control valves, circulation and potentially disinfection, monitoring system, and related items to ensure water quality is maintained in the tanks and the system, avoiding DBP issues.

OB Curtis HSPS and Backwash Electrical

This project will include rehabilitation or replacement of critical electrical components for the backwash and the high-service pumping systems.

Intake Structure Repairs (OB Curtis)

The intake structure at the Ross Barnett Reservoir has fallen into a state of disrepair. The building that houses needed chemical feed equipment and water quality monitoring sensors needs replacement to protect those systems from the weather. Full water quality sensing at the intake allows operators to see changing raw water conditions to prepare treatment processes for changing water chemistry. Additionally, new flow-paced chemical feed equipment can be directly informed by the raw water data collected at the intake structure, ensuring reliable treatment, and minimizing chemical use. The chemical feed at the intake structure is not functional currently. Feeding chemical at the intake reduces build-up of marine growth in the intake pipes and reduces loading on the screens in the plant.

JH Fewell Pump Station Conversion

Sixty-three percent of the assets at J.H. Fewell Water Treatment Plant (WTP) are in poor or very poor condition, needing immediate rehabilitation or replacement. Because of the age and physical deterioration of J.H. Fewell WTP, it is recommended to decommission and convert J.H. Fewell WTP to a booster pump station for the distribution system. This project will include decommissioning and converting J.H. Fewell WTP to a booster pump station.

Replacement Membranes

The project includes the replacement of two of the size aged and damaged membrane cassettes at the O. B. Curtis WTP's membrane treatment train. The remaining four cassettes are being funded by the USACE.

SCHEDULE FOR COMPLETION

This program is scheduled to begin immediately and continue through 2029 with additional funding phases in future fiscal year programs. The 2024 plan presented here will obligate a maximum of $125.7M by September 30, 2024. The entire $450M appropriation will be obligated by 2029.

EVALUATION PROCESS

These investments will be evaluated through the reduction in the need to issue large precautionary boil water notices (more than 500 customers impacted) and system pressure increases as well as improved permit compliance at the water treatment facilities.
