Rosehill Water Treatment Plant - 2017 Annual Water Quality Report

The Annual Water Quality Report summarizes the quality of drinking water from the Rosehill Water Treatment Plant from January 1 to December 31, 2017.

The Rosehill Water Treatment Plant Summary Report is available for inspection.

Description of Drinking Water System

A conventional surface water treatment plant incorporates the following steps in its purification process:

  • Zebra mussel control
  • Travelling screens
  • Coagulation
  • Flocculation
  • Sedimentation
  • Filtration
  • Disinfection
  • pH correction

Rosehill Water Treatment Plant supplies water to the Town of Fort Erie and is located at 300 Rosehill Rd., Fort Erie, Ontario.

The water treatment chemicals used over this reporting period are:

  • Sodium Hypochlorite
  • Aluminum Sulphate
  • Caustic Soda

Monetary Expenses Incurred

To ensure safe and efficient operations, the following major repairs or upgrade projects took place:

  • Rosehill Water Treatment Plant upgrade design - $11,500
  • Crescent Park Elevated Storage Tank decommissioning - $375,000

Notices Submitted

There were no notices submitted in accordance with subsection 18(1) of the Safe Drinking Water Act or section 16-4 of Schedule 16 of O.Reg.170/03 and reported to Spills Action Centre.

Water Quality Test Results

Microbiological

Total Coliform and E.coli bacteria tests are performed on raw, treated and distributed drinking water.

Microbiological testing done under the Schedule 10, 11 or 12 of Regulation 170/03, during this reporting period.

Test Number of Samples Range of E.Coli or Fecal Results (minimum number)-(maximum number) Range of Total Coliform Results (minimum number)-(maximum number) Number of HPC* Samples Range of HPC Results (minimum number)-(maximum number)
Raw 52 0-57 0-1,000 Not applicable Not applicable
Treated 104 0-0 0-0 104 0-48
Distribution 156 0-0 0-0 156 0-165

*HPC (heterotrophic plate count) bacteria indicate biological growth. They are not harmful to humans and do not represent poor drinking water quality.

Operational

Operational testing done under Schedule 7, 8 or 9 of Regulation 170/03 during the period covered by this Annual Report.

Test Number of Samples Range of Results (minimum number)-(maximum number)
Turbidity 8760 0.010-1.592 NTU*
Chlorine 8760 0.62-2.000 mg/L
Fluoride Not applicable  

*NTU (nephelometric turbidity units) is a unit that measures the lack of water clarity.

An analyzer continuously monitors the water treatment process and records results on a predetermined frequency. Continuous monitors use 8760 as the number of samples.

Summary of additional testing and sampling carried out in accordance with the requirement of an approval, order or other legal instrument.

Date of legal instrument issued Parameter Date Sampled Result Unit of Measure
