Obtaining a flusher hydrant permit

The City of Ottawa’s Flusher Hydrant Program issues permits to businesses requiring non-potable water for services such as street cleaning or pool filling. Businesses looking to use City water from flusher hydrants must obtain a permit per vehicle and report their usage. Unauthorized use of a fire hydrant can result in fines.

High Volume User Program

Save money and water with the City’s High Volume User (HVU) Program. The HVU Program offers rebates to property owners for installing eligible water efficient toilets, urinals, spray valves and commercial dishwashers and washing machines.

What are the benefits?

Inefficient use of water increases utility costs and places undue stress on the environment. These negative outcomes can often be avoided by retrofitting inefficient fixtures with devices which use less water while providing equal or superior performance. The HVU program aims to offset the costs when retrofitting water fixtures by providing rebates. Find out how these Ottawa organizations benefitted from the High Volume User Program:

  • Ottawa Community Housing Bank Street location cut $78,000 from its annual water bill
  • Osgoode Properties sees return on investment eight months after installing water efficient toilets
  • Ramphos Holdings Inc. saves money with water efficient toilets and washing machines

An industrial, commercial or institutional property consuming a minimum of  25,000 m3 of water per year

Water main maintenance - Cathodic Protection Program

The City of Ottawa’s Water Services completes preventative water main maintenance to ensure the continued efficient delivery of safe drinking water to your community.

What is cathodic protection?

Cathodic protection is a process that involves attaching a series of magnesium rods (or "anodes") to the outside of a metallic water main or water service to provide corrosion protection to the water main.

 Cathodic Protection

Why are we doing it?

With age, metal pipes corrode and eventually break. Cathodic protection helps prevent this process by transferring the corrosion from the outside of the water main to a “sacrificial” anode.

Why was my street selected?

The City analyzed the frequency and severity of water main breaks in Ottawa over a five year period. From this analysis, locations were identified and prioritized. 

How is it done?

Work crews drill a series of 30 cm (1 foot) diameter holes on City property and insert magnesium (sacrificial) anodes beneath the ground. The anodes are connected together by a wire which is attached to your water service.

Will cathodic protection be added to all water mains?

No. Cathodic protection is for metallic pipes. Today, most water mains are made from PVC.

How will this work impact residents?

  • There will be noise associated with the work.
  • The installation process takes minutes and holes are refilled the same day.
  • Traffic and pedestrian impacts are minimal.
  • Work is done on the outside of the pipe, so water quality and pressure are not affected.

When will the work take place?

The work starts in May and finishes in early-August. Work takes place between 7:00 a.m. and 5:00 p.m.
