ABOUT
Watertight Lining Solutions Inc. is a wholly-owned subsidiary of PUC Inc. that provides an innovative solution to aging water infrastructure.
Quick General Facts:
- Watertight Lining Solutions Inc. (WLS) was incorporated in the fall of 2021.
- WLS uses the Spray-in-Place-Pipe (SIPP) process which uses a polymer lining (Resiline 320) that repairs leaky pipe and returns them back into service usually on the same day.
- Municipalities can save taxpayers millions of dollars over time by using the SIPP process.
- Same day return to service
- Eliminate temporary mains
- Brief road/lane closure
- 120 meters lined per day
- The SIPP process can reduce total project costs by as much as 30%
- WLS is the only authorized applicator of Resiline 320 in Ontario.
- Pipe rehabilitation with Resiline 320 reduces the carbon footprint by up to 75% compared to typical replacement pipe.
How The 6 Step Process Works:
- Assessment and Planning (Utility/Municipality)
- The rehabilitation process begins with a full site evaluation and condition assessment.
- Specific details addressed during this project planning phase include environmental and regulatory compliance, easement restrictions, traffic controls and determining the strategic location of access pits.
- A detailed work schedule is then created in order to minimize impact on traffic, businesses and homeowners.
- Site Prep and Excavation (Utility/Municipality)
- Install all traffic, pedestrian, and worker safety equipment.
- Install bypass piping, if required.
- Access pits, measuring 6’ x 10’, can be excavated one day prior to each lining section reducing the impact on the local community.
- The pipe is isolated, de-watered and a 4-foot section of the pipe is cut out and removed.
- Cleaning and Inspection (Watertight Lining Solutions Inc.)
- The pipe is cleaned using a mechanical cleaning process (rack feed boring, drag scrapping forced air vortex aggregate cleaning, or high-pressure water jetting). This process restores the pipe to its initial capacity by removing any existing biofilm, scale or tuberculation.
- Depending on the pipe substrate and cleaning method used, a series of foam swabs may be used to remove any loose debris and standing water.
- Prior to lining, a CCTV inspection of the entire length of pipe is then completed and digitally recorded. Each service lateral is mapped and closely inspected to ensure it is clear of debris.
- Lining (Watertight Lining Solutions Inc.)
- One worker visually inspects the lining head operation at start up.
- During the lining process, a proprietary software and hardware system monitors and controls the equipment to help ensure proper application in each section.
- Our small equipment footprint typically allows one lane of traffic to remain open throughout the construction process.
- Inspection and Chlorination (Watertight Lining Solutions Inc.)
- The installed liner can be inspected in as little as ten minutes after installation.
- A full CCTV inspection is completed for each section, including each connection.
- A detailed lining report is maintained by the application and copies of all records are provided to the customer (inspection videos, lining printout, lining reports, etc.).
- Disinfection completed in accordance with local or AWWA standards.
- Reinstatement (Utility/Municipality)
- The pipe can be reinstated in as little as 90 minutes allowing same day return to service and eliminating the need for bypass piping.
- Equipment is easily demobilized after each lined section and roadway plates can be used to return normal traffic flow each day.
- Once the section has been lined and reconnected, the access pits can be filled and paved.
