Millions of miles of water, sewer, and storm system pipes lie beneath our cities and streets.

These pipe networks and conveyance systems are the support system for our way of life, transporting safe drinking water to customers and moving wastewater and stormwater to treatment facilities and discharge or reuse.

Addressing aging water infrastructure, meeting regulatory requirements, and making these systems more sustainable and resilient is crucial to ensure communities have safe and reliable water, sewer, and storm systems. Climate change and urbanization place continuing pressure on those systems to perform for future generations.

Leading major conveyance, storage, and tunnel programs around the world, including Abu Dhabi’s Strategic Tunnel Enhancement Programme (STEP) and London’s Thames Tideway Tunnel, CH2M continues to be recognized as a gamechanger in trenchless technology, ranked number one for four consecutive years by Trenchless Technology Magazine.

East Layton pipeline

East Layton Pipeline

Recently recognized as the Utah Construction and Design Project of the Year, the East Layton Pipeline, a critical aging infrastructure pipeline that provides 90% of Wasatch Front’s communities with drinking water, was delivered using a Construction Manager/General Contractor approach which accelerated the project’s schedule. CH2M’s local expertise led to the successful design and construction of the large diameter pipeline despite complexities caused by its close proximity to residential streets with congested utilities.  

Tarrant Regional Water District

Tarrant Regional Water District’s Innovative Wetlands Scheme 

Increasing Dallas-Fort Worth’s water supply by 30 percent, the Tarrant Regional Water District innovative wetlands scheme recovers wastewater from the Trinity River to augment the city’s water supply in the Richard Chambers Reservoir. CH2M collaboratively designed the project’s intake and pumping systems to protect the reservoir and ensure the region has access to high quality water supplies.

DC Water Blue Plains Tunnel

For nearly two decades, CH2M has partnered with the Washington, DC Water and Sewer Authority to manage the largest advanced wastewater treatment facility in the world. As part of a continuing effort to improve water quality and minimize discharges to the Chesapeake Bay area, CH2M designed facilities to reduce nitrogen discharges to the limit of conventional treatment technology.

As communities struggle with balancing water quality, supplies and cost, it’s our goal to minimize lifecycle cost and maximize system performance.
