� Mechanical Point Repairs
� Quick Lock
� Quick Lock Sleeve
� 6 in – 72 in.
� Can be used for storm, potable water, wastewater,
industrial pipes, conduits and culverts.
� 145 to 217 psi max internal pressure. Max external
pressure is 21.7 psi.
An Evaluation of Trenchless Point Repair
Solutions for Pipes of Varying Inner Diameter
and Offset Joints
� Locking mechanism prevents shrinkage after expansion.
� Gears are also covered to prevent snagging of waste, build up of sludge
and protects it from root cutter or cleaning nozzle.
� Sleeve is installed on an inflatable packer on wheels. 1-2 minute
installation.

� Develop a wastewater pipeline performance deterioration
model
� Iterative process
� Many different types of models out there from statistical, stochastic
or probabilistic, advanced mathematical, and heuristic models
� Objectives
� Determine list of parameters and collect data
� Update performance index to assess the performance of gravity
lines
� Predict future performance of the pipe lines using updated
performance index
� Integrate the developed model with desktop and online GIS
platforms for an effective dissemination
