We're helping communities rebuild their lives and build back stronger.
In the aftermath of natural disasters around the world, access to reliable wastewater infrastructure is one of the first—and most critical—steps toward recovery. Watch how E/One’s pressure sewer system, which is built for these moments, offers a fast, adaptable solution for communities when and where they’re needed most.

Why Pressure Sewers?
Design & Deliver
Pressure sewer, a true plug-and-play system, is easy to transport and install quickly in communities recovering from natural disaster.
Adaptable Installation
Directional drilling and temporary surface-laid HDPE lines allow for use in even the most challenging or remote environments – no heavy equipment required.
Scalable for Any Situation
Whether you're serving residents who stayed or preparing for those returning home, our system can expand to meet evolving community needs.
Viable and Cost-Effective
Eliminate critical I&I issues over the entire life of the system.
Future-Proof Placement
Treatment facilities can be placed above floodplains, protecting infrastructure from future natural disasters.
Rebuilding Infrastructure
in Christchurch, New Zealand
Following the devastating earthquakes of 2010 and 2011, Christchurch turned to pressure sewer systems to rapidly restore its wastewater infrastructure. The rebuild relied on the technology’s quick install, cost-efficiency, and resilience—installing nearly 150 km (93 miles) of pipe during the recovery phase alone. Today, that number has more than doubled, reflecting the long-term confidence in this scalable solution.
Initially used for temporary service in affected areas, pressure sewers became a preferred permanent option post-February 2011.
The resilience of E/One’s pressure sewer system is most apparent in the flexible, shallow-buried networks that resist damage from ground movement, are easy to repair, and allow quick, low-cost connections – making pressure sewer systems a vital component of Christchurch’s infrastructure recovery.
The Stronger Christchurch Infrastructure Rebuild Team (SCIRT) adopted E/One as a key technology to provide permanent wastewater services in catchments where gravity networks had suffered extensive damage or were at high risk from future seismic activity.
E/One's pressure sewer system is designed with both the immediate crisis and the long-term future in mind—restoring indoor plumbing quickly, while laying the foundation for a more resilient, environmentally sound recovery.
