What are the leading drivers for municipal water and wastewater projects?

There are multiple megatrends impacting municipal water agencies including droughts, climate change, environmental regulations, aging infrastructure, decarbonization, and cybersecurity. Regions that are susceptible to or currently experiencing water shortages face an increasingly urgent need to develop sustainable and diverse water supply portfolios. One Water strategies, intelligent planning, and automation advances have facilitated our clients’ ability to integrate and manage multiple sources at any given time. Climate uncertainty, environmental protection, environmental justice, and energy resilience for water production will drive innovation in the municipal water sector for the next decade.


What sets Tetra Tech apart from other firms that work in the water market?

Tetra Tech has been ranked number one in water by Engineering News-Record (ENR) since 2003. ENR also ranks our firm #1 in Water treatment and desalination because of our volume of work in this practice area. Our experts are well versed in desalination for municipal, commercial, and industrial customers. We have significant expertise in water supply, distribution, treatment, and storage, and we have designed hundreds of water treatment facilities ranging from 1 million gallons per day (MGD) to 500 MGD in capacity. Our team is focused on Leading with Science® and leveraging technology to deliver sustainable and scalable solutions.


How is Tetra Tech helping clients address emerging contaminants of concern?

Per- and polyfluoroalkyl substances (PFAS), microplastics, and harmful algal blooms are at the forefront of regulatory planning for our clients. Increased regulatory focus on drinking water contaminants, coupled with social justice and environmental protection priorities, will drive the state and federal regulatory climate. Many states have set PFAS regulations in advance of federal regulation due to the potential for serious adverse health impacts. PFAS characterization, treatment, and management can be complex due to their persistent and ubiquitous nature.

Tetra Tech has supported government and commercial clients with PFAS characterization and management. We are at the forefront of pilot testing various treatment technologies including granular activated carbon, ion exchange, and reverse osmosis.  We also are implementing a multifacility treatment program for Orange County Water District in California.


How will digitalization transform the water industry over the next decade?

The digital transformation of the water industry will have a significant impact on the way our clients supply, treat, and deliver water to their customers throughout the next decade.  Tetra Tech is helping our clients to remove data silos and unlock the potential of their data, enabling them to use new sources of business intelligence across their planning, capital delivery, and operations teams. Tetra Tech supports major water utilities with supervisory control and data acquisition modernization and major cybersecurity programs as they address an evolving digital landscape. These programs support a sustainable and secure digital water future and will prepare our clients to benefit from the convergence of automation, advanced analytics, intelligent planning, and asset management in the water industry.
