WATER ISSUESAccording to the EPA major expenditures will be needed to replace water transmission and distribution lines over the next twenty years. A recent EPA study stated that water systems throughout the country are in a state of massive deterioration and could bring forth many health issues.
Line failures are due to the following reasons:
- Under sizing of current lines
- Tuberculation build up of existing lines
- Joint failures in existing lines resulting in Inflow and Infiltration I/I
PIPE BURSTING FOR WATER LINE REPLACEMENTWhen designing water line replacement projects, pipe bursting should be considered first due to the social impact of the dig and replace method of construction and its ability to upsize a line. During the pipe bursting process a bursting unit splits and/or fractures the existing pipe while simultaneously installing a new pipe of the same or larger size into the annulus created by the unit’s forward movement.
When going to a bigger size pipe, things such as soil conditions, original trench width, clearance and surrounding utilities need to be considered. Pipe bursting for water applications can be accomplished with several types of new pipe, however, over 95% of all water pipe installed by the pipe bursting method has utilized High Density Polyethylene Pipe (HDPE). HDPE pipe is a tough, durable and yet inexpensive pipe. HDPE pipe is now also guaranteed for over 100 years of service life! For more information, please refer to PUCC’s Contact Page
BURSTING BENEFITS
- Replace pipe ranging in size from 4 to 54 inches
- Can be used to replace pipe for the same size and to replace pipe by up sizing.
- Only trenchless pipe rehab method that can actually upsize the existing pipe.
BURSTING EFFECTIVE FOR:
- Clay or VCP pipe
- Concrete or RCP pipe
- Asbestos cement or AC pipe
- Plastic pipe
- Ductile iron pipe DIP
- Steel pipe or cast iron pipe
STATIC BURSTING METHODWater line pipe bursting is accomplished by the Static Pipe Bursting method. The static pipe bursting consists of five simple steps:
- Dig insertion and exit pits at the beginning and the end of line segment. One to place the bursting machine and the other to use as a pipe entrance pit.
- Shuttle your static rods from starting point to the end point in the line.
- Attach the expander and pipe to the static rods
- Pull the rods, expander and pipe back toward the bursting machine.
- Reconnect the services
