Water and Wastewater Information

Annual Flushing Program

Haldimand County’s Water and Wastewater Division will begin flushing fire hydrants throughout the distribution system as of April 8, 2024. Flushing will be conducted between the hours of 8:00 a.m. and 3:00 p.m.  The program will be completed by the end of June.

Please be advised that residents may experience a drop in water pressure as well as some discolouration of the water during this process. The discolouration of the water is only temporary and does not indicate a problem with the water. If the water does become discoloured, turn on a cold water faucet for a few minutes to clear the water line before doing any laundry or cleaning.

We apologize for any inconvenience that this system maintenance may cause.

Current water restriction: Level 1

Level 1 – Careful Use. There are no restrictions for water use.

The Water & Wastewater division of Haldimand County manages the municipal water treatment and distribution system and the collection and treatment of wastewater to ensure access to clean, safe drinking water and the proper treatment of wastewater.

Notice to Caledonia and Cayuga Residents

As of November 2018, the City of Hamilton will begin adding orthophosphate into the municipal drinking water system as part of their Corrosion Control Program .

Locates and Sewer Safety Inspections (SSI)

To arrange for a locate or a Sewer Safety Inspection (SSI), please call Ontario One Call at 1-800-400-2255.

Please note: all plugged sewer calls will require a SSI to be done to rule out a potential cross bore situation before County staff will attend a plugged sewer call.  There is no charge for the SSI.

Cross bores are natural gas pipes that have been inadvertently installed through a sewer or septic pipe.  Cross bores pose a danger, which is why Union Gas has implemented the Utility Cross Bore Safety Program.

Important reminder to Industrial, Commercial and Institutional wastewater users regarding Fats, Oils and Grease (FOG)

In accordance with Haldimand County’s Sewer Use Bylaw 1443/14, every business or institution (hospitals, nursing and retirement homes) where food is cooked, processed or prepared is required to have a grease interceptor properly installed, cleaned and maintained on a regular basis.  This can be done by a certified and licensed grease removal contractor.  However, if an owner wishes to clean the grease interceptor themselves, it is important to dispose of the contents properly.  Solidified grease at the surface should be removed and put in the garbage for disposal.  Liquid grease should be put into a container for recycling by a liquid grease recycler.  Local grease recycling companies can be found by doing a quick online search.  These companies provide proper storage bins and will schedule regular pick ups.

FOG over time can build up and cause costly sewer back ups and overflows into the business.  Haldimand County reserves the right to limit rodding services to businesses that have repeated sewer back ups due to grease build up.

What can you do to prevent FOG from going down the drain?

  • Place a screen over drains to prevent solid food particles from going down the drain
  • Recycle FOG by a grease recycling company
  • Wipe or scrape FOG from dishes and pots prior to washing; place cooled grease in the garbage
  • Use a grease caddy to skim FOG collected in the grease interceptor
  • Train employees in the proper disposal of FOG
