At AECOM, we develop sustainable wastewater treatment systems to meet today's environmental challenges. We take an integrated and sustainable approach, which is essential to the effective management of wastewater and wastewater systems and the protection of our public waterways and drinking supplies.

We are leaders in the wastewater industry and our teams of professionals provide the highest quality professional wastewater engineering services, including:

  • Water quality modeling

  • Wastewater collection

  • Municipal wastewater treatment

  • Outfall Wastewater reuse

  • Residuals management

We collaborate with clients to develop comprehensive master plans, identifying affordable infrastructure improvements that meet the most challenging wastewater problems.

Our wastewater experts encompass the full range of treatment systems, including all aspects of water and global warming cycles. 

Our capabilities incorporate such processes as advanced membrane bioreactors, enhanced nutrient systems and advanced bio-solids dewatering and oxidation processes. 


Our goal is to help develop treatment systems that provide:
Superior-quality reclaimed water for irrigation or commercial reuse clean power from bio-solids and waste. 

Solid waste by-products for beneficial use.  Our experts analyze the operations of lift stations, collection pipelines, and treatment facilities, and look for deficiencies that are likely to develop as the population increases and sewer-system components deteriorate. 


We help clients collect, convey, treat and find beneficial uses for effluent. Whether a client requires the design of a new plant or interceptor, an upgrade to a lift station or an integrated approach for water reclamation, our professionals have the expertise and experience to handle any global water assignment. We are a consistent and reliable partner for industries as they strive to comply with more stringent regulations.
