What is a water audit?

A water audit takes 7 days to complete and is conducted by the City of Guelph’s preferred consultant. During the audit, the consultant will:

  • Inspect water using fixtures and appliances in a sample of suites to determine:
    • toilet flush volumes
    • toilet leakage using toilet leak test strips
    • showerhead flow rates
    • kitchen and lavatory faucet maximum flow rates
    • the presence or absence of faucet aerators and the type of faucet aerators (if present)
    • the overall condition of all water using fixtures and appliances
  • Install monitoring equipment to track your building’s water use

Water audit report

Following the audit, the consultant will write a report that outlines:

  • Water use statistics for your building, building equipment and building processes
  • Suite inspection results
  • Evidence of unusual water demand patterns and indicators of excessive leakage in the building (if applicable)
  • Retrofit recommendations

Retrofits that save money and water will be recommended for your building in the report including estimated water reductions. We will help you invest in retrofits by providing rebates and financial incentives from the following programs:

  • Blue Built Home: Rebates for installing water efficient toilets and other water efficient fixtures in individual units
  • Water Smart Business: A financial incentive for updating process equipment including water softeners, HVAC system, cooling towers, boilers and chillers.
  • Residential Water Sub-Meter Program: Rebates for installing sub-meters in your building
