The District’s 10-Year Capital Improvement Program (CIP) Update is a planning tool that establishes proactive asset management, facilitates financial planning, promotes organizational workload balance, and informs the Board and the public about the District’s infrastructure needs, upcoming projects, and proposed capital expenditures. The CIP encompasses all engineered studies and projects related to improvements, repairs, rehabilitation, and replacement of the District’s plant, collection system and pump stations, and marsh assets. The following information provides an overview of the program’s recent progress.
The District is currently conducting an influent flow meter study at the plant to examine the feasibility, potential locations, and technological alternatives to install these meters for the treatment plant. The study is scheduled to be complete in March.
The UV Disinfection Replacement Project will primarily replace the existing UV disinfection equipment and controls that are now 28 years old and through proper maintenance and care, have exceeded their useful service life, with new equipment and controls. Other assets in the UV process area will also be replaced, including the Class 3 water reuse pump station (with the addition of a hydropneumatic tank), the crane structure, influent and effluent gates, the motor control center and its associated programmable logic controller, process control instrumentation, and various other electrical and operational upgrades. The construction period began in October 2021, with on-site activities at the plant scheduled to begin this spring and conclude in November 2022. The total project cost is will be approximately $5,500,000.
For the District’s collection system, a capacity assessment study began in September 2021 to update a previous 2013 study, including an update to the District’s collection system hydraulic model. This study will assess the District’s ability to adequately convey peak flows to the plant, identify any pipelines and/or pump station equipment in need of upsizing, and update land usage and development changes in the District service area. The collection system hydraulic model is an essential tool that enables the District to conduct hydraulic analyses which facilitate engineering and administrative control over potential impacts to collection system capacity. The study is scheduled for completion by June 2022 at the cost of approximately $216,000.
The Manhole Repair/Replacement Project was completed in September 2021 and included work at more than 30 manholes, one pipeline repair, and various minor repairs at several other sites at the total cost of approximately $960,000.
The Pipeline Cleaning & Televising Phase 1 cleaned and televised approximately 25% of the 73 miles of pipeline that make up the entire collection system and conducted 514 manhole inspections. Phase 1 cost approximately $468,000 and was completed in June 2021. The Pipeline Cleaning & Televising Phase 2 will clean and televise an additional 50% of the entire collection system and conduct nearly 1,200 more manhole inspections, and is currently under design. Field activities are tentatively scheduled to begin in spring 2022 with an estimated cost at $941,000. A future third and final phase will complete the remaining 25% of the collection system and manhole inspections.
A project to replace approximately 434 feet of defective 8-inch sanitary sewer and one manhole along Howe Road is currently under design, with field activities tentatively scheduled for 2022 or 2023. The total project cost is estimated at $937,000.
A draft of the 10-year CIP Update is planned to be presented to the Board in March, with the final version recommended for Board approval in April or May. To view a copy of the current Board-approved 10-year CIP Update, please visit https://www.mvsd.org/reports.
