We must rebuild Salt Lake City’s water reclamation facility.
To ensure Salt Lake City continues to have access to clean, safe, high-quality water – now and for years to come – that can be used by people, businesses and industry, then treated and safely returned to the environment in a continuous and responsible manner, Salt Lake City Department of Public Utilities (SLCDPU) is building a new Water Reclamation Facility.

Why rebuild the facility?
- As the City’s only wastewater treatment facility, it must operate reliably and without interruption 24/7/365. The City cannot run without an operational water reclamation facility. The Facility is 55 years old, has aging infrastructure and is near the end of its lifespan, therefore it needs to be replaced to ensure continuous treatment of wastewater for the City.
- New State and federal water-quality regulations starting January 2025, require the reduction of phosphorus in treated wastewater before it is returned to the environment. The existing Water Reclamation Facility is not designed to treat wastewater to meet these new regulations in a sustainable, efficient, or cost-effective manner. It is also anticipated that additional nutrient and water-quality standards will be required in the future. The new facility will use a biological nutrient removal (BNR) process that is designed to reduce phosphorus as well as other nutrients in the wastewater. The new facility will be designed in a manner that enables Salt Lake City to meet the new phosphorus regulation as well as anticipated potential future regulations.
- The existing Water Reclamation Facility was not designed or constructed to meet current building, seismic, electrical, and other current code requirements. Replacing the existing facility with a new facility designed and constructed in accordance to current code requirements provides increased safety during operation of this facility, and reliability and resiliency of this critical facility in the event of fires, earthquakes, or other extreme events.
- The City’s residential and business population is growing steadily, resulting in increased demand for water and wastewater to be treated. While the new facility is being designed to match the existing plant capacity, provisions are being included to accommodate potential future expansion of the plant should additional capacity be required.
- A new, state-of-the-art Water Reclamation Facility – that meets all state and federal safety regulatory standards and provides a modern, safe way to treat water and return it to the environment in a responsible manner – is good for everyone.
The Water Reclamation Facility’s critical role – it’s the City’s only wastewater treatment plant and services more than 200,000 customers over roughly 110 square miles – requires taking a strategic, methodical approach to its construction. Because it’s simply not an option to go without wastewater-treatment services, planning must ensure that the existing Facility continues operating without interruption while the new facility is built.
The Water Reclamation Facility sits on 135 acres in northwest Salt Lake City, near the Rose Park Golf Course. The complex includes 29 buildings and 20 processing units. The new Facility will be built within the existing site. New buildings will be constructed, some existing elements will be retained, while others will be removed or decommissioned until they can be removed.
SLCDPU is working with engineering consultants to complete additional analysis and design of the new Facility. Building the new Facility is one of the City’s largest-ever public works projects. Estimated cost of the project is $528.3 million, paid for with user fees, State and federal grants, and other sources.
Site-preparation work for the new facility begins fall 2019, with major construction starting in spring 2020; completion is anticipated in 2025.
SLCDPU’s top priority is to deliver high-quality, safe, clean drinking water to all its customers, collect the water that is used, treat the wastewater and return it to the environment.
Water reclamation facility site plan.
SLCDPU’s Water Reclamation Facility is located east of Redwood Road between 2300 North and Rose Park Golf Course. The new facility will be built just west of the current facility, after which the old facility will be decommissioned and the land repurposed. There are some elements of the existing Facility that will be reused. All major construction will take place within the existing facility boundary. A small pump station at the south end of the complex will be moved to the main site and also be rebuilt and enlarged.
Key elements of the new Facility include:
- Biological nutrient removal (phosphorus)
- UV disinfection
- Energy capture and reuse
- Odor control
- Reuse of biosolids
- Addition of educational components

The reconstruction will be implemented in phase with a project completion date of 2024
Wastewater treatment process.
The wastewater treatment process used at Salt Lake City’s Water Reclamation Facility is designed to clean wastewater and safely return it to the environment. After going through a multi-step process, treated wastewater is discharged into the Northwest Canal, which flows into Farmington Bay and, ultimately, into Great Salt Lake. Biosolids from the process are removed and put to beneficial use for landfill cover and soil fertilization.
Water reclamation facility sustainability elements.
Salt Lake City has wisely invested in its green mission to help our community conserve resources, reduce pollution, minimize carbon emissions, and ensure a healthy, sustainable future. The City’s approach to sustainability and programs to support it have made us a sustainability leader among American cities.
As a sustainability leader, the City is always pushing to accomplish more. We are evaluating various sustainability measures to improve effectiveness and efficiency of the new Water Reclamation Facility. We’re committed to building a model Facility, while also being prudent with public funds.
OUR SUSTAINABLE APPROACH
On January 12, 2017, Salt Lake City Mayor Jackie Biskupski signed the Sustainability Infrastructure Executive Order, calling for citywide collaboration on sustainability. The executive order includes:
- Net-zero energy buildings
- LEED design standards
- Sustainable infrastructure
- Comprehensive energy management
This is how we will apply the Sustainability Executive Order to the rebuilding of the Water Reclamation Facility:
|EXECUTIVE ORDER||AFFECTED FACILITIES|
|Executive Order Title||Administration Building|
|LEED Design Standards|
|Sustainable Infrastructure||Campus Infrastructure|
|Comprehensive Energy Management||Existing Buildings|
We’ve established a clear plan to integrate the sustainability elements that make the most sense for each part of the new Water Reclamation Facility. Our process is to continuously assess all planning, design and construction decisions to optimize long term community value.
