Water, Wastewater and Stormwater Rates

Water rates for residents in London are calculated based on the following: 

  • Water Usage Charges (shown as m3)
  • Wastewater Usage Charges (shown as m3)
  • Infrastructure Connection Charge

Residential Water Utility Bill Sample:

Example of a 2020 residential hydro bill






Water Usage Charge

Billing for 14m3:

7m3x 0= $0 (Water consumption used in the month - first tier)

7m3 x  $2.3069 = $16.15 (Water consumption used in the month- second tier)

Water usage charge for 14m= $16.15

Wastewater Usage Charge

Calculation based on water consumption

Billing for 14m3:

7m3 x 0= $0 (Wastewater consumption used in the month - first tier)

7m3 x $2.0503 = $14.35 (Water consumption used in the month - second tier)

Wastewater usage charge for 14m3 is $14.35

Usage charges for Water and Wastewater for 14m3

$16.15 + $14.35 =$30.50

Infrastructure Connection Charges (charges are listed below)

Water Connection Charge $16.20
Wastewater Connection Charge $13.72
Stormwater Charge $16.71
Fire Protection $1.66
Customer Assistance $0.25
Total $48.54

* Residents who have the need for a larger meter, such as those who live in homes located in low pressure zones, are subject to a different rate.

2020 Water, Wastewater and Stormwater Rates

Water Rates

In the existing structure customers pay for water charges based on their usage or volume consumed each month and a capital renewal charge (water connection charge).  All residential, institutional, commercial, and industrial customers will pay a fixed monthly charge based on the size of their water meter and then a volumetric charge based on the amount of water used each month. This blending of fixed and usage charges is intended to continue to promote conservation by continuing to give the customer control of their bills by reducing their monthly usage. Most residential homes will have a 16mm water meter.

Monthly Water Connection Charge: Water connection charge is calculated using meter size.

Stormwater Charges

The property’s total square meter area (hectares) will determine the monthly charges for Stormwater. The fees that each customer pays goes toward the construction, maintenance and operations of the storm sewers, ditches, watercourses, retention ponds, roadways, etc.

 Property Size and Type Stormwater Drainage Charge ($/month) Monthly $ per Hectares
Land area 0.4 hectares or less 16.71 n/a
Residential land area 0.4 or less without a stormdrain within 90m 12.56 n/a
Land area above 0.4 hectares n/a 139.10


Fire Protection Monthly Charge

All of the watermains have been designed and constructed to deliver high quality water to homes and businesses, and the fire hydrants that protect them. This sophisticated water distribution system that London manages actually lowers homeowner’s insurance rates for the whole City.

Each year City Water crews visit every hydrant three times to conduct routine frost checks in the winter and maintenance as needed.

The charges are broken out into 3 rates based on the class of customer.

Property Size and Type Rate in $
Residential and Low Density Residential 1.66
Institutional, Commercial, Industrial, Medium Density Residential, High Rise under 5 hectares 11.12
Institutional, Commercial, Industrial, Medium Density Residential, High Rise above 5 hectares 55.54


Customer Assistance Program

The City has a 25-cent fixed fee that is applied to each monthly bill for all single family residential water customers in London. These funds are collected over the year and applied to the customer assistance program, if the money from these funds has been used-up at any point in the calendar year, then the program will be suspended until January 1st of the following year when the funds are topped up again.

The new charge will contribute to a special reserve fund and will be drawn against for:

  1. Helping low-income Londoners deal with crisis situations on their monthly water bills using existing programs managed and delivered through partnerships with London Hydro, the Salvation Army, and the City. An annual fund of $100,000 will be kept and topped up each year to help those in need;
  2. Helping low-income Londoners make changes to the fixtures in their homes to help lower  their monthly water use. On average 40% of home water use is from the toilet; and
  3. Helping London’s water customers pay for water and wastewater charges one time that have occurred as a result of a plumbing failure in their homes.

To be eligible:

  • Property must be a residential property being serviced by a single water meter paying the customer assistance rate    
  • The monthly water usage during the plumbing failure is at least three times the average monthly consumption
  • Excess usage cannot be as a result of outdoor water usage (pool or hot tub filling, irrigation, etc.) or neglect of privcate property (ie. failing to winterize outdoor taps)
  • Proof of permanant/actual repair must be supplied
  • A decrese in the monthly water usage was observed AFTER the plumbing failure was repaired
  • The application and all required documentation must be submitted within two months of detecting the issue and completion of the repair
  • Have never received this one-time relief before


What is ineligible:

  • Home was vacant or premises were unattended when the plumbing failure occurred
  • Plumbing failure occurred at an industrial, commercial or institutional property
  • Plumbing failure occurred at a multi-residential property (ie. duplex, triplex, etc.)
  • Usage was unexplained, due to purposeful damage (ie. broken pipe from construction) or neglect (ie. failing to keep temperature inside home at acceptable level)
  • The water utility account has been previously approved for the Customer Assistance Program


Aggregated Water Consumption

For customers that have multiple meters installed at their facility, of which at least one is a 100mm water meter (or larger), they can request to have their water consumption aggregated before applying the volumetric rates. The meters must be located close to each other and cannot be for two facility properties that are not side by side. The customer is eligible for the program starting in the following billing period after the request is made and accepted by the City.

The class or type of user is not important, only the size and number of water meters that service the customer along with their proximity to each other. As an example, chain restaurants that have multiple locations would not be eligible for this benefit but a large industrial user with multiple meters at one facility with multiple buildings would.

Metered Effluent Charges

For industrial customers that use more than 15% of the water measured by the water meter in their consumptive use, there is an opportunity to have the wastewater volume metered. The WM-28  By-law Part Four outlines the rules associated with this program.

The customer is required to divert all flows leaving the site to a single effluent meter. In the rebate program the customer purchases, installs, calibrates, and maintains the effluent meter on their sanitary connection into the City’s sewer. After the City has approved the meter installation, the customer receives a rebate based on the difference between the volume consumed and the volume discharged.

Customers should review the by-law and contact the City to determine the effluent meter type required to facilitate automatic meter reading. There could be additional electrical, process, or automation work required by the customer to develop the initial set-up which is at no cost to the City.

Please call 519-661-2489 ext. 5081 if you wish to participate in this program or for information on rates. Please include your approximate water use, billing number, and expected difference between the measured water use and effluent volume.

Storm Fee Reduction Program

Every developed parcel in the City of London with a municipal water service pays a stormwater charge on their London Hydro water utility bill. Properties that are greater than 0.4 hectares in size pay a per hectare charge. These properties may be eligible for a stormwater charge reduction on their water utility bill. In accordance with Municipal By-law WM-28 (Section 3.4.2), the City of London has a reduction program for stormwater rates of up to 50% for Industrial, Commercial and Institutional (ICI) properties over 0.4 hectares.  

Industrial, Commercial and Institutional water utility customers with a property size greater than 0.4 hectares may apply for a water billing stormwater charge reduction.  To receive a reduction, submission of a Stormwater Rate Reduction Application is required along with required supporting documents such as but not limited to a storm drainage report,  prepared and stamped by a Professional Engineer, that shows the subject site has stormwater management practices that go above and beyond established stormwater requirements and warrants a rate reduction.  This will be reviewed and accepted by the City and to the satisfaction of the City Engineer. 

Generally, the intent of the Stormwater Rate Reduction Program is to recognize ICI properties which are discharging a lower volume of runoff to the municipal system due to increased pervious areas or through construction of green infrastructure with an infiltration function. The following cases may be eligible for the Stormwater Credit:

Case 1: Pervious Surface Credit: where the Owner can demonstrate that the runoff coefficient (C-value) of the property is less than the City Design & Specification Standard for the Land Use/Zoning. Please note that the lower runoff coefficient will become permanent upon acceptance of the credit. Therefore, any future development of the site will be expected to implement green infrastructure or other stormwater management measures to manage additional volumes and maintain the revised coefficient.

Case 2: Green Infrastructure – Infiltration System: where source controls are constructed by the Owner to reduce the total volume of runoff from the site, such as rain gardens or bioswales with the ability to infiltrate.  The credit may relate to the surface area of the pervious feature(s) and/or the volume infiltrated into the soils (depending on soil conditions).

The volume captured by the feature(s) should be identified as a percentage reduced from the original or post-development runoff. 

Other Stormwater normal/standard Stormwater practices are not considered as being part of the reduction such as parking lot or rooftop storage, dry/wet ponds, or oil grit separators.  The reduction will only be applied if there is a demonstrated reduction in runoff volume to the municipal system.  

Customers who are interested in a Stormwater reduction at the early planning stages are encouraged to submit a request as part of the Site Plan Application process.

The Stormwater Rate Reduction Program Information Form provides details for the application types, report requirements and application process.

How to apply

Please fill out the Stormwater Rate Reduction Application and submit all required documentation and send to or mail copy of application to:

Stormwater Rate Reduction Program

9th Floor City Hall

300 Dufferin Ave.

PO Box 5035

London, ON

N6A 4L9

City Staff from Stormwater Engineering Division will contact the applicant upon review of the application. If a reduction is approved, the rate will be retroactive from the application submission date and be granted for five years, provided no changes or further development occur on the site during this time. Any alterations to the site after the reduction approval date will require reapplication to the Stormwater Rate Reduction Program.
