If properly maintained, CIPP lining can last for fifty to sixty years. Without being cured, has a ten to fifteen-year lifespan on its own. This is due to the possibility of the liner slipping and becoming unstable. A pipe that has already been cured might have several layers of epoxy applied to it over time.

The CIPP liner is inserted into the pipeline and inflated using compressed air or steam to create a tight seal against the pipe walls. The liner is then cured using heat or UV light to harden it into a rigid, durable pipe. The lining installation process typically takes a few hours to a day, depending on the length of the pipeline.

Once the lining is cured and inspected, any service connections that were previously cut or removed are reconnected. The system is then tested to ensure that it is functioning properly and there are no leaks or issues.

A
Access Point
 A location in a sewer system designed for inspection or maintenance, often used to facilitate CIPP or SIPP installations.

B
Backflow Prevention
 A system designed to prevent contaminated water from flowing back into the clean water supply, crucial during sewer rehabilitation processes.

C
Cured-in-Place Pipe (CIPP)
 A trenchless rehabilitation method involving the insertion of a resin-saturated liner that cures in place to create a new, seamless pipe.

D
Drainage System
A network of pipes that carry excess water away from a building; rehabilitation methods like CIPP and SIPP enhance its effectiveness.

E
Epoxy Resin
A type of resin used in the CIPP method that hardens to form a durable, waterproof pipe lining.

F
Flushing
 The process of clearing debris and contaminants from sewer lines before rehabilitation work begins, ensuring optimal conditions for CIPP and SIPP.

G
Grouting
 A technique sometimes used in conjunction with CIPP to fill voids around the pipe, providing additional support and preventing soil movement.

H
Hydrostatic Pressure Testing
 A method to assess the integrity of sewer lines before and after rehabilitation, ensuring that no leaks exist post-repair.

I
Infiltration/Inflow (I/I)
 The unwanted entry of water into sewer systems; controlling I/I is a key focus during sewer rehabilitation efforts.

J
Joint Sealing
 The process of repairing joints between pipe segments, crucial for maintaining the integrity of sewer lines post-rehabilitation.

K
K-value
 A coefficient representing the thermal conductivity of materials used in pipe rehabilitation; important for assessing energy efficiency.

L
Liner Installation
The process of placing the resin-saturated liner into existing pipes in the CIPP method, a critical step in sewer rehabilitation.

M
Manhole Rehabilitation
 The process of restoring manholes to prevent leaks and enhance access for sewer maintenance, often integrated with CIPP and SIPP methods.

N
No-Dig Technology
 Techniques, including CIPP and SIPP, that allow for the repair of sewer lines without excavation, minimizing surface disruption.

O
Odor Control
 Measures taken to prevent foul odors from escaping sewer lines, often improved through effective rehabilitation methods.

P
Polymer Coating
 A protective layer sprayed onto the interior of pipes in the SIPP method, enhancing corrosion resistance and extending the lifespan of the pipe.
