Plan Recommendations
The major items that are recommended for improvement are:
  • Monitoring and confirming estimated flows and determining impacts of infiltration and inflow (I&I) in asbestos cement (AC) pipe.
  • Replacing AC pipe in areas with high I&I, or poor pipe condition at a cost of $105,000 per year over the next 10 years.
  • Upgrading the existing lift stations - 23 lift stations exist with the Horizon Village facility having the greatest upgrade need at a cost of $1,302,000.
  • Upsizing mains that will need to accommodate development - Two mains will need to be upsized within the next 10 years at a cost of $98,000 and will be covered through Development Cost Charges.
