Trenchless Definition

Trenchless technologya type of subsurface construction work that requires few trenches or no continuous trenches. It is a rapidly growing sector of the construction and civil engineeringindustry. It can be defined as "a family of methods, materials, and equipment capable of being used for the installation of new or replacement or rehabilitation of existing underground infrastructure with minimal disruption to surface traffic, business, and other activities."

Open Cut vs. Trenchless

An estimated 75% of infrastructure replacement/rehabilitation is done utilizing open cut vs 25% trenchless technologies.

Digging of open trenches is a common practice for laying of almost all underground utility services

Growing Cities have continued hurdles with vehicular traffic and environmental challenges

Installation Methods Comparison

Open Cut installation• Huge Restoration Cost• Impacts Communities and Business• Extended Construction Time• Adverse Environmental Impact

“Happy Communities Make Happy Politicians”

Trenchless Methods Reduce• Project Cost• Business Interruption Cost• Construction Time• Political Cost

United Kingdom – British Gas Development of Swagelining & Pipe bursting in 1970’s

Pipe Bursting & Swagelining History

History– Methods developed by British Gas (1970’s) and patented for

gas distribution

– Success led to potable water crossover

– Pipe bursting – 100,000,000 feet installed in past 32 years

– Pre-chlorinated method approved by Florida DEP in conjunction with AWWA in 1999

– Swagelining - 29,800,000 feet installed in the past 32 years

Today– Over 85% of water mains replaced via pre-chlorinated pipe

bursting across Europe

– AWWA M28 approved pre-chlorination process

Compression Fit HDPE Pipe lining Process

Compression Fit HDPE Pipe lining Process

Compression Fit HDPE LiningEngineering Value

– Follows path of existing utility

– Maintains or slightly increases flow

– Install HDPE pipe that is Solution to the Problem

Fully structural HDPE (Class IV plus)– Design for both Internal Pressures and External Loading

– Full “Stand-Alone” Capability

Semi structural HDPE

Thin walled HDPE

Compression Fit HDPE LiningConstruction Value

– Insertion lengths up to 5,000 feet

– Pipe sizes of 4” through 65” Static Pipe Bursting most suitable 4” through 16” Water Transmission & Sewer Force Mains most suitable 16”

through 65”

– Negotiates field bends

– Surgical excavations of 92% less than open cut

– Environmentally sensitive

– Undertake projects year round

– Social costs reduced

Compression Fit Installation –Preparation of Host Pipe

Camera/man entry inspection

Cleaning

Proving pig sent through host pipe to ensure free bore path

Compression Fit Installation –Butt Fusion

Sections of HDPE pipe are butt fused together

External bead removed

Compression Fit Installation -Shuttle Rods through host pipe

Compression Fit Installation –Attach pipe once rods reach entry pit

Compression Fit Installation –Reducing Die

HDPE pipe has an OD slightly larger than the ID of the pipe to be renewed

Pipe is pulled through a reduction die which temporarily reduces its diameter

Compression Fit Installation –Rods recovered at exit pit

Rods are removed from the exit pit as pipe is pulled into place

For the next pull the exit pit becomes new entry pit

Compression Fit Installation –HDPE enters receiving pit

Pulling force removed

Natural relaxation of HDPE

90% of reversion occurs in 2 hours

Remaining reversion occurs overnight

Compression Fit Process –Results

No gaps - all annular space is eliminated

Fully structural pipe

Interactive pipe

Thin walled liner

Compression Fit Installation –Final Connections

Advanced Engineered Solution

Follows existing utility path

Provides largest Internal Diameter possible

Long pull lengths

Rapid installation

Cost effective

Solution to problem

Long term design life

Rural areas – environmentally friendly

Urban areas – reduced social costs

Pre-chlorinated Pipe burstingEngineering Value

– Follows path of existing utility Reduces potential for 3rd party utility damage Eliminates identifying new easements Engineering design hours reduced

– Ability to increase pipe diameter – Replacement vs. Rehabilitation

Life Cycle Cost Analysis HDPE has design life of 100 plus years

– Many states do not require permits Classified as line maintenance

Pre-chlorinated Pipe burstingConstruction Value

– Production rate of 300 – 600 feet per day– Crew visible to homeowners for one day– Surgical excavations along project with a reduction in

restoration up to 86% Compact equipment 90% reduction in carbon outputs Environmental sensitive areas not impacted

– Limits change orders– Social costs reduced as process enables better traffic

flow, less intersection closings and less business interruptions

Project Considerations - Upsizing

Size for size or one upsize replacement most common

Feasibility Study to determine risks– surface heave

Analysis:

- Host pipe material

- Existing depth

- Soil conditions

- Flow rates/C-factor

- Location

- Intersecting utilities
