Pipe cleaning expertise and advanced equipment combine to recover sewer pipe hydraulic efficiency
National Underground Group’s experienced, professional cleaning crews assess the pipe cleaning job, and based on quantity of debris and the condition of the pipe, they determine the best process and equipment for the job. Our cleaning crews specialize in providing pipe cleaning services that exceed client expectations, while minimizing disruptions to traffic and the environment.
We offer pipe cleaning solutions for pipes of any diameter using advanced equipment that emits high-pressure water through a variety of nozzles and cutters that meet our clients’ specific requirements. After scouring and sanitizing storm or sewer pipes, we apply powerful vacuum to remove debris.
National Underground Group also offers pipe jetting services as well as mechanical cleaning methods:
- Pipe jetting blasts water under high pressure to eliminate buildup, scale and blockages accumulated in pipes
- Mechanical cleaning pushes or pulls special devices through pipes to remove hard deposits from pipe’s interior wall
Pipe cleaning technology provides capabilities for a range of pipe diameters
National Underground Group uses Hvidtved Larsen 315 RECyclers to conduct large-diameter pipe cleaning during live flow as well as volume-production cleaning on small-diameter pipes. The Larsen ensures a safe operating environment and provides numerous benefits:
- Drinking water not used to clean sewers
- Bypass not required for large-diameter cleaning
- Remote truck operation permitted
- Single, flexible-tube vacuum hose eliminates rigid tubular connections over open maintenance holes
- System replenishment from street hydrants is eliminated
- Single initial vacuum of wastewater in flowing pipe enables day-long jetting operations
- Flow is 124 GPM versus 80 GPM for traditional hydro-vacuum combination cleaning trucks
We use Vactor 2100 series hydro-vacuum combination cleaning trucks to perform conventional cleaning of pipes with diameters ranging from 6 to 120 inches.
Our conventional cleaning trucks feature several advantages:
- 1,600-gallon water tank
- 15-cubic-yard debris tank
- 3-stage vacuum fan
- Telescoping boom with 8-foot travel
- Cleaning delivers capability of 80 gpm at 2,500 psi
- System eliminates maintenance to v-belts or belt drives
- Blower silencer limits noise emissions
Comprehensive pipe cleaning restores designed flow capacity and aids rehab
Complete pipe cleaning provides important operational benefits:
- Restores pipe’s designed flow capacity
- Removes sewer pipe debris to facilitate inspection
- Enables pipe rehab, such as pipe-in-pipe relining or mechanical spot repair
- Prevents sanitary sewer overflows (SSOs), resulting in risks to health, the environmental and property
National Underground Group owns and manages a truck fleet with the latest Hydro-Vac system technology. Our 24/7 on-call dispatch service enables us to respond in the event of a system emergency.
