Water & Sewer Locates

Utility marking and locating is the process of identifying and labelling underground public utility mains and cables to protect them from damage during digging or excavation.

Before any digging or excavation can take place, you must notify all utility companies so that they can locate and mark their underground utility. You can arrange for locates of several utilities through OntarioOneCall.com at 1-800-400-2255.

Water & Wastewater Locates

Town of Blue Mountains water and wastewater locate markings are valid for sixty days, after which time you must have them re-marked.

Specific paint colours are used to designate different utilities; red for electrical power lines, yellow for gas lines, orange for communications or signal lines, blue for potable water lines, purple for reclaimed water lines, green for sewer lines, white for proposed construction, and pink for survey markings.

If you require additional support or have questions about your Ontario One Call ticket status, please contact the Water & Wastewater Division.
