The cleaning of sewers 36” in diameter and larger present challenges to conventional cleaning methods such as combination sewer cleaning units producing flows of 80 GPM @ 2,000 PSI. Those challenges include:
- Larger debris accumulations
- Larger size debris
- Higher sewer flows
- Access issues, including sewer depths and water resources
To address those challenges, Terra Contracting has developed a cleaning system that delivers 200 GPM at 2,000 PSI and an inline water recycler. The benefits of using Terra’s high flow system include:
- Eliminating costly bypass pumping by cleaning large diameter sewers under live flow conditions
- Reducing the disruption to everyday activities by conveying larger debris volumes back to an extraction point
- Safe and efficient removal of large size debris (such as boulders, manhole lids, car parts, etc.) from one access point
- Remote setup and cleaning of sewer systems that are not near a road system with minimal or no disturbance to landscape
- Closed-loop system provides zero odor and zero particulate emission
- Use of an Inline Water Recycler allows the system to reuse the water extracted from the sewer system instead of utilizing a portable water supply such as a hydrant system
- With high flow units, the water source is critical and the demand can be taxing on aging water mains
Terra’s system is an efficient, cost effective approach to improving a waste water collection system’s capacity.
