The city of White Rock had a sewer main that needed replacement just up from the west end of the beach with the exit pit was just west of the intersection of West Beach Avenue and Anderson Street. The run was west on West Beach Avenue and many house were located along the street making for a tight situation for the lay down area for the fuse sections of HDPE pipe. The best situation was to fuse the sections into two runs with a final fuse of the section done just prior to the burst.
8:50 a.m. The rods were inserted into the host pipe and sent up to the exit pit.
10:14 a.m. the rods entered the entrance pit. While the rods were being installed, the steel plates that had been securing each of the service laterals were removed. The two sections of the HDPE pipe were moved into place and the pulling head was installed onto the East end of the HDPE pipe. The pipe was then staged at the entrance pit waiting to be attached to the pulling rods.
10:21 a.m. the Pulling head was attached to the rods.
10:24 a.m. The new HDPE pipe enters the host pipe
10:33 a.m. The pulling head enters the first of the Service lateral connection pits
10:35 a.m. The pulling head enters the first of the gas service connection inspection pits. No problems with excess soil. No contact was made with the gas service line.
10:40 a.m. The pulling head enters the second of the gas service connection inspection pits. No problems with excess soil. No contact was made with the gas service line.
10:49 a.m. The two sections of HDPE pipe are fused together without interrupting the pipeburst in progress. The fusion machine is one wheels and can easily roll with the pipe being inserted.
11:20 a.m. a gas service had been previously excavated for observation while the pulling head was going past the gas service. A large amount of the material had to be dug by hand to clear the soil that had been pushed into the excavation by the pulling head. The Gas service was left intact.
11:31 a.m. A Steel Robar type repair couple had to be cut away from the bursting head. This was only done to ensure clearance for upcoming gas and water service connections.
1:07 p.m. Another Steel Robar type repair couple had to be cut away from the bursting head as it came into and service lateral connection pit.
1:40 p.m. The pulling head reached the Exit pit (Pulling pit) Approximately 140m of pipe installed in 3 hours and twenty minutes.
In early 2017, The City of Maple Ridge put out to tender a contract for an "Experimental" pipe burst in an environmentally sensitive area of Maple Ridge and through part of Kanaka Creek Park. The host pipe was 375mm (15 …See Project
The District of North Vancouver had a 900mm CSP storm sewer that had been failing for 10 years. Numerous efforts to clean the pipe had resulted in the bedding, surrounding the pipe, migrating into the pipe when cleaning efforts were …See Project
The King George Highway was opened a year after King George's Royal Visit to Canada in 1939. He planted trees alongside the highway in South Surrey and over time these have become part of the community. When the underlying sewer …See Project
An alternate tendering process where the contract is awarded to one entity which comprises both engineering and contracting.
Because PW Trenchless Construction offers such innovative solutions for underground utilities, it is often beneficial for the owner to request solutions based on a performance specification. This allows PW Trenchess to offer unique solutions while working with equally innovative engineering companies.Learn More

In this day & age of pipe systems reaching the end of their projected lifespan, pipe replacement and pipe rehabilitation have become major fields of engineering.
PW Trenchless Construction provides viable options such as pipe bursting, loose fit lining and internal pipe re-construction whether partial & fully circumferential.Learn More
The aging culverts under roads and highways in many case have reached the end of their engineered life-span. We consider the rehabilitation or replacement of these culverts to be vital to our built environment.
PW Trenchless has been a pioneer in working with MOTH, railway companies and municipalities in developing rehabilitation methodologies for the hundreds of thousands of culverts that currently exist in BC. We have offered solutions in both procurement and construction from design-build to sliplining, invert rehabilitation and full circumferential relining.Learn More
Often pipe failure can be concentrated to one section, for various reason, leaving the rest of the pipe in good condition. The repair of these localized failures are know as external point repairs (EPR's).
EPR's demonstrate PW's ability to work as both a trenchless and civil contractor, completing EPR contracts using our civil contracting skills and assisting other pure trenchless contractors who only have the capacity to work in an existing pipe.Learn More
Pipe upsizing is the fundamental concept of pipe bursting.
The vast majority of pipes are less than or equal to 200mm in diameter, but with today's densification practices of urban design, there is a major demand to increase current capacity to handle extra flow. Pipe bursting provides the ideal solution to this issue, particularly in an urban setting .Learn More
Horizontal Directional Drilling is a low impact Trenchless construction service where pipe is installed in a shallow arc along a bore path which has been created by a drilling rig. Often the terms Horizontal Directional Drilling (HDD) and Directional Boring are used interchangeably, but in our industry we use the word “boring” when we utilize smaller sized drilling rigs with small diameters for short crossings in the hundreds of feet, and we use the word “drilling” when we utilize larger rigs with large diameters for long crossings in the thousands of feet.Learn More
When you join PWT, you become part of a community of people who are engaged in the most innovative practices in the Trenchless Industry. We have been instrumental in setting up a scientific method for cities to gain carbon offsets/credits from their use of trenchless construction. This system has been reviewed by the BC Government and has been approved as of December 2018. We expect to see it in common use shortly.
