Mayor's Report - May 2006


WATER SYSTEM — PREFERRED OPTION PREDESIGN STUDY

Mayor Ralph Drew

Last November the Dayton & Knight engineers attended an information meeting to provide an overview of their study on water source and distribution options, and on Municipal Election Day the Community Opinion Question received the assent of 69% of the residents who voted. As a result, Council intends to pursue infrastructure funding when the opportunity next presents itself.

An analysis of the water source options affirmed the preferred option as the District of North Vancouver (DNV) submarine water main crossing. Accordingly, a Request For Proposals for a follow-up study to pre-design the preferred option was prepared and distributed to five engineering firms. The objective of the pre-design study is to enhance consideration by senior governments of an application for funding grants given that the study will provide both design details and quantified costing.

Two proposals were received, and on May 15th Council awarded the project to Dayton & Knight Consulting Engineers at a cost of $46,000; and also has applied to the Province for a funding grant. Key aspects of the Predesign Study include:

  • Confirming best alignment route(s) through a review of marine charts, geographic references, and consultation with VPA and DNV.
  • Identifying alignment considerations for costing, environmental constraints, and public lands that include built-in redundancy for damage and maintenance.
  • Identifying required environmental assessments for the marine crossing.
  • Undertaking detailed hydraulic modeling of the proposed system that builds upon the DNV model.
  • Determining the regulatory approval requirements of VPA, BERC, GVWD and the DNV.
  • Pre-designing hydraulic requirements and infrastructure costing, predicated upon alignment and DNV modeling.
  • Reaffirming the total capital cost to construct the water main distribution system not existing at the time the study is being prepared.
  • Providing a 20-year projection of the annual capital debt servicing cost per household for the water supply distribution infrastructure.
  • Water Use Efficiency Study

    The municipality has also made application to the Province for a grant to undertake a Water Use Efficiency Study, the goal of which is to reduce the volume of potable water required through water conservation, thereby reducing infrastructure construction and operating costs of the water distribution system. As the Village’s potable water system is currently being planned, this is an ideal time to review options to manage water consumption. Once identified, the options can be readily incorporated into the future water supply infrastructure.

    One of the most important conservation tools is water metering, which involves measuring the flow of water throughout the distribution system. The flow data is used to assess system losses and water consumption and, if applicable, water rates. Typically, this involves placing meters at each service connection in the system, referred to as universal metering. The principal impact of universal water metering would be a reduction in potable water consumption, and would also provide the following benefits:

  • a better understanding of water demand and unaccounted losses;
  • the ability to charge fairly for water on basis of consumption;
  • a better concept for system planning; and
  • realistic projections for future water demand.
  • An important aspect of the Water Use Efficiency Study is the cost benefit analysis which would include:

  • estimate of the water reduction potential of a universal metering program;
  • types of meters and technology available;
  • meter location including indoor versus outdoor installation;
  • meter reading methodology (manual, telephone, radio, TouchRead);
  • billing software;
  • cost estimate (capital, operation and maintenance costs);
  • recommended water metering bylaw;
  • cost benefit of metering costs versus potential savings; and
  • implementation considerations.
  • As the foregoing indicates, Belcarra Council is actively working toward the objective of obtaining infrastructure funding for a municipal potable water distribution system.
