In order to communicate the consumption data related to water usage, each meter has a transmitter connected, which sends this information to the Utility and Finance Departments.

The current transmitters were installed over 10 years ago, and due to their age, the internal batteries have begun to fail, leaving the device unable to transmit data.

These devices are located inside dwellings which has resulted in a large backlog of unaddressed replacements during the pandemic, with approximately 10% of meters no longer being read. This has resulted in inaccurate billing information, as the consumption for these accounts is estimated.

Repaint the interior and exterior of the metal water tower to protect the cleanliness of the water storage facility.

Exterior and interior inspections were completed and it was determined the existing coatings have reached the end of their useful life. This water tower was last painted in 2002.

This project was previously budgeted for in 2022. Bids were higher than anticipated, so the project is being re-bid in 2023.

Installation of sanitary sewer main to serve the future development east of Hadley Avenue and south of 4th Street.

This sewer main needs to be installed prior to the Gold Line improvements to avoid future reconstruction of retaining walls, roadways, and traffic impacts that would result if the main was installed after the Gold Line improvements are completed.

This project totals $215,000; $100,000 in 2022 & $115,000 in 2023.

Lift Station 14 currently has a hole in the pipe elbow and the rails need to be replaced. Staff also recommends replacing the current cables used for pump maintenance with stainless steel rails as they allow for more efficient access to complete repairs.

Due to the Willowbrooke development, it is important that this lift station is operating efficiently. The Lift Station pumps are from 1989, and the last time they were rewound and seals replaced was in 2006.

Well No. 9 has gone 15 years without inspection. The inspection process includes analyzing and replacing parts if needed. This is also Oakdale's highest producing well within the distribution system.

Typically these repairs are performed in the spring or fall when there is lower demand. The inspection and repairs need to be done by a certified Well company.

The age of the current pumps at Lift Station 1 are approaching the end of their service life.

Typical lift station pumps have an average service life of 15 years and these pumps have exceeded that time. It is recommended to replace before failure occurs.

Repaint the interior and exterior of the metal water tower to protect the cleanliness of the water storage facility.

Exterior and interior inspections were completed and it was determined the existing coatings have reached the end of their useful life. This water tower was last painted in 2003.

This well has previously experienced insufficient snow cover for insulation, which has led to pipes freezing. This pipe is critical as it provides the reading level of Water Tower No. 2. Because of the excavation needed to add insulation, the drain field will also need to be improved as it backs up inside of the building.

By insulating the pressure line to Well No. 3 the risk of freezing is greatly reduced and will help ensure accurate data collection and water levels.

Removal of unused PRV at Eberle park entrance and replace the piping with a single gate valve.

The PRV is no longer needed on this line. By keeping the line in place, any issues with the line may impact the water distribution system.

Modifications and upgrades to the existing well control system to prepare for the development of a centralized water treatment plant.

The detection of PFAS in Oakdale's ground water is triggering the need to provide additional treatment to the City's supply wells. In order for this additional treatment to be done in an efficient and practical way, the treatment should be centralized.

Replacement of wells that had PFAS. These wells are currently located in residential areas, which limit the ability to treat the water on site.

The detection of PFAS in Oakdale's ground water is triggering the need to provide additional treatment to the City's supply wells. In order for this additional treatment to be done in an efficient and practical way, the treatment should be centralized. This will require the replacement and relocation of wells closer to the treatment facility.

Installation of electronic pressure reducing valves (PRV) in Well No. 1 and Well No. 8 after decommission.

By controlling the PRV's electronically, staff is able to prevent ice from forming during the cold winter months by changing pressure and the water level in the tower. Currently staff must cycle wells on and off to prevent the formation of ice, which isn't energy efficient.

This recommendation is based upon the decommissioning of Well No. 1 and Well No. 8 as part of the PFAS settlement.

Replacement of the pumps at Lift Station 17 and raising the Motor Control Center (MCC), which is used to control the electronics in the lift station. Xcel will also raise the transformer that is located on site because it is sitting to low.

The structure was built in 1993 and the station pumps are reaching the end of their useful life. The MCC Panel is rotted at the bottom due to sitting in water after heavy rains.

Connection of three new wells to the treatment plant.

The wells have to be drilled with a separation of approximately 1,000 feet to minimize interfering with the draw capacity of each well. It will be necessary to connect these wells to the treatment facility.

Excavations and new impervious areas of buildings/pavement associated with the new treatment facility, wells, and transmission lines will require the management of runoff.

Compliance requirements to treat runoff from new imperious areas that drain to surface waters.

Seal/remove two wells that have PFAS.

The wells exceed the HBV's for PFAS and are located in residential areas that preclude onsite treatment and are too far away to connect to a centralized treatment facility.

Replacement of the Lift Station Pumps, Piping, Rails, Motor Control Center (MCC) Panel and installation of Variable Frequency Drive (VFD).

The structure was built in 1996 and while the station has been maintained, it is necessary to replace pumps, piping, rails and MCC Paneling. The pit also needs to be sealed to keep station functioning efficiently.

The current generator is not large enough to operate more than one pump during a power outage.

With the Willowbrooke addition increasing the volume to this Lift Station, new generators are needed to ensure uninterrupted service in the event of significant inflow during a power outage.

Seal and remove well that has PFAS.

This well exceeds the HBVS for PFAS and is too far away to connect to the centralized treatment facility.

Once the centralized treatment plant is built at the existing public works campus, this temporary treatment facility will no longer be necessary. This project will remove the treatment equipment so the building can be converted to a different use.

Centralized treatment is more efficient than treating at the individual well sites. It would be appropriate to consider repurposing the building.
