- Rapid installation
- ± 2500 feet (800 meters) per week;
- Little excavation when compared to open cut;
- Adjacent infrastructures are not disturbed by work;
- Less complaints from residents during work;
- Added life for water main:
- Increased pressure and flow capacity
- (Hazen-Williams coefficient > 120);
- Corrosion resistance;
- Regained structural capacity.
- Economic considerations:
- Rehabilitation costs generally less expensive than traditional open cut;
- Reduced # of pipe breaks;
- Reduced treatment and pumping costs;
- No further intervention on rehabilitated water mains;
- Reduced social costs.
