Rabbittown Area Watermain Lining Project

Share on Facebook Share on Twitter Share on Linkedin Email this link

The watermain in the Rabbittown area has received rehabilitation - cleaning and structural lining in order to reduce maintenance issues and improve water service.

This project has been completed

Businesses and homes will receive water through a temporary above ground water piping system installed along the street. Residents will be notified directly by the contractor if their properties are included in the project area and access is required to provide temporary water service. Two-way traffic and pedestrian access will be maintained where possible, delays are to be expected. Every effort will be made by the contractor to maintain driveway access to properties located within the work site. 

The City of St. John's began rehabilitation work on watermains in several areas of the city in order to reduce maintenance issues and improve service.

Cured-in-Place-Pipe (CIPP) lining of watermains is a trenchless pipe rehabilitation method which consists of cleaning and structural rehabilitation of the existing watermain via installation of a CIPP liner.

PROJECT FUNDING

The project was approved to receive cost shared funding through the Provincial - Territorial Infrastructure Component - National and Regional Projects (PTIC-NRP) of the New Building Canada Fund and the Clean Water and Wastewater Fund. The funding partners for this project are the Government of Canada, Province of Newfoundland and Labrador and the City of St. John's.

    Why has the contractor not yet cleaned up the mess left in the area from the past two years of water main relining which is now complete? There are many streets in this area which still have loose asphalt, bits of pipe, and, in some cases, plastic underlay strewn about which can result in a slip and fall incident. The area around the newly installed fire hydrants has not been properly covered in. Jamie Hunt (project engineer) assured me that this clean up would be taken care of after the work was completed and here we are one year later with a mess.

    Mike Manning asked over 2 years ago

    The Contractor completed an initial clean-up of the work area following completion of construction activities in November 2018; however, cold temperatures caused the recycled asphalt (used for driveway ramps) to freeze onto the sidewalk/road surface in areas, making the clean-up more difficult and less effective.  Snow accumulations at that time, also prevented the Contractor from completing a final site clean-up prior to the end of the 2018 construction season, thus, final clean-up was deferred to Spring 2019.

    The City has advised the Contractor the clean-up of 2018 work areas is a priority and must be completed as soon as possible.  The Contractor has committed to starting the final clean-up in the next few days.

    The landscaping around the newly installed fire hydrants will be completed in early summer, as sodding becomes available.

    Why did the city choose the relining procedure over the replacement of water main pipes?

    Mike Manning asked almost 3 years ago

    The City’s decision was based on the many advantages of rehabilitating existing watermains using CIPP Lining vs replacement of watermains:

    • Cost savings
    • Time savings
    • Minimum water service disruption, as residents are placed on a temporary water system.
    • Minimal traffic disruption (2-way traffic maintained) since only small excavation pits are used to access the pipe, as opposed to the excavation of the entire street.
    • Minimum tear-up of the street, as work is conducted from small access pits which can be reinstated, as opposed to requiring full reconstruction of the street asphalt/road base.
    • No disruption of sewer service, as sometimes is the case when sewer services are encountered during watermain replacements.
    • Individual water services do not have to be excavated, as they are reinstated from inside of the rehabilitated pipe.

    What is the approximate/exact cost difference between the relining of pipes versus replacement of pipes? What is the expected difference in time to complete each repair option? Relining versus replacement?

    Mike Manning asked about 3 years ago

    CIPP Lining - Construction Tender Price (Low Bid) - $8.15M

    Replacement – Construction Cost Estimate (Class D) – 14.2M

    Replacement would also require external engineering services at an estimated cost of $2.1M; whereas, CIPP Lining is completed with in-house engineering staff.

    The entirety of the 2017-18 CIPP Watermain Lining project was scheduled to be completed in two constructions seasons.  We do not have a comparable schedule for watermain replacement (varies significantly between projects and contractors); however, it is anticipated that it would require a significant longer construction timeline.  CIPP lining projects are typically completed in less time than watermain replacement projects.

    Why is access required to the home? Are they putting in a new line or just connecting to an existing external water tap?

    Clyde asked over 3 years ago

    A: The contractor will require access to your home to inspect the existing water service shut-off valve to ensure it is operational. Non-operational valves will be repaired or replaced by the contractor. When notified by the Contractor, the water service valve will have to be shut-off to prevent water from the temporary service connection from flowing back into the existing watermain during construction. And, we are connecting to the outside tap to provide temporary water during construction.
