� Mechanical Point Repairs

� Quick Lock

� Quick Lock Sleeve

� 6 in – 72 in.

� Can be used for storm, potable water, wastewater,

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
