North Plant Construction
Construction of upgrades at the District's North Plant in West Bountiful began in July 2024. Alder Construction was awarded the contract for the project, which is expected to be completed in 2027.

Headworks
A new headworks building will replace the aging headworks facility that - with the help of periodic upgrades and renovations - has served the community for over 60 years. As the first stage of wastewater treatment, the headworks plays a critical role by removing large debris—such as sticks, rags, rocks, trash, and plastics—to protect downstream equipment, improve operational efficiency, and enhance the overall effectiveness of the treatment process. The new facility will feature modern screening systems along with pumping and flow measurement capabilities, providing a comprehensive and efficient start to the treatment process.
Primary Clarifier
Primary treatment is a physical, gravity-based process that takes place in large tanks called clarifiers, where heavier solids can settle and be removed. The addition of a primary clarifier at the North Plant will increase capacity, improve efficiency and support future growth.
MBBR
Construction of a Moving Bed Biofilm Reactor (MBBR) at the North Plant will allow the District to meet reduced permit limits from the Utah Division of Water Quality for ammonia that can't be achieved using the existing trickling filter process units alone. An MBBR is a biological process that uses suspended plastic media to grow beneficial microorganisms, or biofilm, which break down organic pollutants.
MBBR Pump Station
A new pump station is needed to lift treated water from the plant's existing trickling filters up to the higher elevation of the MBBR basins. Pump stations are essential when gravity flow is not possible due to elevation differences, moving water between treatment stages to ensure continuous and effective processing.
Anaerobic Digester
Concentrated solids collected and removed from the primary clarifiers and other physical, gravity-based process treatment units are stabilized through a biological process called anaerobic digestion. This process breaks down organic matter in the absence of oxygen, reducing odors, pathogens that can cause disease and the overall volume of solids. The addition of a new anaerobic digester will provide needed capacity for ever-increasing amounts of solids and support future growth.
Dewatering Building
To reduce handling, transport, and disposal costs, excess water is removed from treated solids, referred to as biosolids, to create a thicker, more concentrated product. Historically, the District has used solar drying beds for this dewatering process. However, with growing volumes of biosolids and limited space for expansion, the existing beds are no longer sufficient.
To meet current and future needs, the District is building a new mechanical dewatering facility. This system, which will sit in the footprint of two of the plant's original drying beds, functions like wringing out a wet sponge—removing as much water as possible to reduce volume and improve efficiency.
Administration Building
The District’s current administration building, which is over 65 years old, sits on the planned site for the new anaerobic digester. To ensure safe access to our community for decades to come, the building is being relocated to the east end of the treatment plant property, next to Legacy Frontage Road. Construction of the digester cannot proceed until the new building is complete.
