Wastewater Treatment and Biosolids Management
Trusted partners in wastewater innovation.
Precise, Reliable Solutions for Community Success
Wastewater treatment utilities face several key challenges on their mission to protect public and environmental health. Energy consumption, plant optimization and regulatory compliance, compounded by the presence of emerging contaminants, are chief among them. For decades, Kiewit has delivered reliable solutions to the complex issues facing wastewater treatment facilities. Our jobs are done right the first time thanks to our deep expertise and in-house resources that deliver all facets of a project with transparency and simplicity for our clients.
Predictable Excellence in Wastewater Treatment
Wastewater treatment projects are often foundational for any community, and when they flip the switch, they want no surprises. At Kiewit, our laser-focused execution, quality and commissioning work generates projects that work exactly as you envision.
Sustainable Biosolids Management Solutions
A key component of wastewater treatment is biosolids handling. This unavoidable aspect often challenges many utilities. Kiewit offers industry-leading biosolids management solutions to make the process more effective and efficient.
Anaerobic Digestion
This critical first step in biosolids treatment, with optimized operation and configuration, can produce enough biogas for use as an alternative energy source. Our experts can help you maximize your biogas production.
Dewatering
Several dewatering methods and process efficiencies are available to reduce sludge volume and ultimately enable sustainable recycling back into the community. Let our experts help you find the best approach.
Drying
Drying further reduces sludge volume and improves stability of the biosolids, thus increasing their versatility for other renewable applications. We can also leverage our industry experience to identify sustainable options for waste heat recovery.
RM Clayton Headworks Improvements
To navigate the maze of major underground utilities at this wastewater plant, Kiewit deployed extensive use of ground-penetrating radar and vacuum potholing techniques and leveraged significant support of its structural engineering group and other experts and worked closely with plant operations personnel to carefully excavate and place new equipment.
Explore the project
Tres Rios Biosolids Solar Drying Facility
The Tres Rios Wastewater Reclamation Facility (WRF) in Tucson, Arizona, will not only reduce the volume of biosolids but produce higher quality Class A biosolids. It will have the capacity to treat at least 180 wet tons per day of Class B biosolids and transform it into the equivalent of 45 dry tons of Class A variety.
