Wastewater Treatment

Safeguarding water quality and transforming wastewater into a valuable resource

Wastewater treatment

Wastewater is no longer waste — it is a valuable resource in a circular economy, essential to protecting public health and the environment. As infrastructure ages and regulations tighten, utilities must manage risk, improve performance and unlock new value from every drop.

With deep technical expertise across treatment, biosolids, resource recovery and reuse, we support clients through the full asset lifecycle — from planning and design to optimization and operations — protecting water quality, recovering resources and strengthening resilient, day-to-day performance.

Industry leadership

Recognized global leader in wastewater treatment plant design, ranked No.1 by ENR, with proven technical insight across complex wastewater programs. 

End-to-end delivery

Integrated technical, program management and operational capabilities applied from planning and design through construction and long-term operations to support resilient, high-performing assets.

Digital & AI

Advanced digital tools and AI-driven insights used to optimize energy and chemical use, reduce emissions and improve treatment plant performance across the asset lifecycle.

Jacobs supports utilities to shift from pollution control to water resource recovery by integrating advanced treatment, energy optimization, biosolids reuse and nutrient recovery. Our solutions improve performance, reduce lifecycle costs and create long-term environmental and community value. 

Jacobs works with utilities to respond to aging infrastructure, wet weather impacts and tighter regulations around nutrients and emerging contaminants such as PFAS. We deliver planning, modeling and treatment solutions that strengthen resilience, protect water quality and support future regulatory needs.

Jacobs is a recognized leader in addressing wastewater treatment emissions. We combine energy optimization, resource recovery and deep expertise in process emissions to reduce energy use, lower greenhouse gas emissions — like methane and nitrous oxide — and support progress toward energy and carbon neutrality. 

Jacobs designs and optimizes nutrient removal solutions that protect water quality and receiving waters. From advanced biological treatment to process intensification and modeling, we enable utilities to meet stringent nitrogen and phosphorus limits reliably and efficiently.

Jacobs uses digital solutions like Intelligent O&M and Aqua DNA to help utilities optimize wastewater operations. By combining data, analytics and insights from the 300+ facilities we operate, our solutions improve energy and chemical use, support proactive decision-making and enhance system reliability and efficiency.
