All owners or occupants of Premises within the City of Edmonton share costs associated with
Stormwater service. Stormwater utility charges are levied on all owners or occupants of Premises
that receive Water Services and all other Premises that benefit either directly or indirectly from the
conveyance of Stormwater by EWSI facilities. Stormwater utility charges are calculated based on
a monthly rate using the following formula:
Stormwater utility charge --- AxIxRxrate, where
A is:
the area of premises (m2), and
the proportion of building lot area attributable to each unit for
multiple units sharing a single building or Premises
I is
the development intensity factor of 1.0, except for Premises where
Customers have demonstrated that they contribute significantly less
stormwater per m2 to the City's sewerage system during rainfalls
than other similarly zoned Premises by making an application for a
reduction in the intensity development factor pursuant to this bylaw.
R is
the runoff coefficient based on the zoning of the Premises.
Rate is
-
the stonnwater utility rate.
The zoning designation used to calculate a Premises Stormwater utility charge is the zoning
designation determined by the City of Edmonton through its bylaws or otherwise. If a Premises
zoning designation is not referenced within the Runoff Coefficient Table, EWSI shall, in its sole
discretion, use the zoning designation within the Runoff Coefficient Table that most closely aligns
with the Premises zoning designation.

Notwithstanding the above, if a sanitary sewer trunk charge is levied on a premises as a result of
the redevelopment or renovation of the premises, the sanitary sewer trunk charge will be calculated
using the following formula:
sanitary sewer trunk charge = A -- B
A is:
The sanitary sewer trunk charge that would have been levied based
on the above fees;
B is:
The sanitary sewer trunk charge previously levied and paid for the
premises prior to the redevelopment or renovation on the premises;
or
If the redevelopment or renovation of the premises is for residential
use classes, then the sanitary sewer trunk charge that would have
been paid had a sanitary sewer trunk charge been levied with
respect to the development that existed on the premises prior to the
date of the redevelopment or renovation.
If the result is a negative figure, the sanitary sewer trunk charge will be
deemed to be $0.

Part IV -- Wastewater Treatment Rates
Wastewater Overstrength Surcharges: Supplementary Information
1.
Key Terms
a.
Biochemical oxygen demand (BOD) means the quantity of oxygen required for
the biochemical degradation of organic material and the oxygen used to oxidize
inorganic material such as sulphides and ferrous iron during a 5-day, 20 degree
Celsius incubation period and may measure the oxygen used to oxidize reduced
forms of nitrogen, as determined by using a standard procedure.
b.
Chemical oxygen demand (COD) means a measure of the oxygen equivalent of
the organic content of a sample that is susceptible to oxidation by a strong chemical
oxidant, as determined by using a standard procedure.
c.
Flow monitoring point means an access point to the building drain, building sewer,
private drainage system or sewer service for the purpose of collecting representative
samples of the wastewater being released from the premises.
d.
Oil and grease means any solvent extractable material of animal, vegetable or
mineral origin, as determined by using a standard procedure.
e.
Phosphorus means all forms of phosphorus in a sample, as determined by using a
standard procedure.
f.
Suspended solids means the portion of total solids retained by a filter, as
determined by using a standard procedure.
.g.
Total Kjeldahl Nitrogen (TKN) means organically bound nitrogen plus ammonia
nitrogen, as determined by using a standard procedure.
2.
Determination of Wastewater Overstren th Surchar es
EWSI or its agent:
a.
will collect a composite sample of the wastewater being released over any 24 hour
period or part thereof;
b.
will determine the concentration of the surchargeable constituents in the sample,
using a standard procedure;
c.
will calculate the average concentration of each constituent from a minimum of four
(4) composite samples taken over a period of more than seven (7) days, and not
longer than a 12 month period;
Wastewater Services Bylaw No. 20865
Page 13 of 16
Schedule 1
Part IV -- Wastewater Treatment Rates
d.
may, where the concentration(s) of the overstrength constituent(s) are in the same
range as those used to establish the existing overstrength surcharge, use the existing
mean concentrations to set the overstrength surcharge rate until such time as the
concentrations fall outside the existing range;
e.
will calculate the average number of kilograms of each surchargeable constituent
per cubic metre of wastewater, that exceeds the concentration indicated in Part IV
"Wastewater Overstrength Surcharge" and "Wastewater Additional Overstrength
Surcharge" of this Schedule; and,
f.
will calculate the Wastewater Overstrength Surcharges which will appear on the
Customer's utility bill using the following formula:
.5 = V[PB(CB -- 300) + Pc (Cc -- CA) + PG (CG -- 100) + Pp(Cp -- 10) + Ps(Cs -- 300) + PN (CN -- 50)]
1000
Where:
-
S is the overstrength surcharge in dollars;
-
V is the total water consumption in cubic metres (m3) (or, if approved, sewer
metering);
-
PB, PC, PG, Pr, Ps, and PN are the Overstrength surcharge set out in Part IV
for each kilogram of BOD, COD, oil and grease, phosphorus, suspended
solids, and TKN, respectively.
-
CB, CC, CG, CP, CS, and CN are the average concentrations in milligrams per
liter (mg/L) of BOD, COD, oil and grease, phosphorus, suspended solids
and TKN, respectively, in the sampled wastewater.
-
CA is 600 or double the average BOD concentration in mg/L, whichever is
greater.
-
The additional surcharge is calculated using the above formula but
substituting 3000, 400, 75, 3000 and 200 for 300, 100, 10, 300 and 50,
respectively, and Cac is 6000 or double the average BOD concentration in
mg/L, whichever is greater.
-
Where the remainder of a subtraction is a negative number, that component
of the formula becomes equal to zero.

3.
Application of Wastewater Overstrength Surcharges
a.
Single Business, Multiple Sewers:
Where the wastewater from a premises is released through two or more building
sewers and where there is no accurate measurement of the individual flows being
released, the release that would produce the highest surcharge will be used to
determine the overstrength surcharge on all releases.
b.
Multiple Businesses, Single Water & Sewer Service:
Wastewater released through a single sewer service from a premises with two or
more separate businesses serviced by a single water service will be considered as
being released by the person responsible for the payment of the utility bill for that
water meter.
c.
Multiple Businesses, Multiple Water Services & Single Sewer Service
Wastewater released through a single sewer service from a premises with two or
more separate businesses, each serviced by separately metered water services, will
be considered as being released from each of the separate businesses, in proportion
to the separate business' water consumption, unless it is shown to the satisfaction
of EWSI or its agent, by the owner of the premises, that:
i.
the portion of the wastewater that is overstrength is being released from only
one of the businesses serviced by a separate metered water service on the
premises; and,
ii.
the release from that business can be monitored separately from the other
businesses.

Overstrength Surcharge, or both, by applying in writing to EWSI to have the specific charges
reviewed.
The Customer making the request will supply to EWSI:
a.
analytical data from analyses of composite samples:
i.
collected over the period of time over which the surcharge was calculated;
ii.
collected from the flow monitoring point in accordance with section 2(a) of
this Wastewater Overstrength Surcharge: Supplementary Information;
iii.
analyzed in accordance with section 2(b) of this Wastewater Overstrength
Surcharge: Supplementary Information; and,
iv.
supported by the analytical data indicating the accuracy and precision of the
analyses; and

Services to Customers whenever EWSI reasonably determines, or when EWSI is
directed by an authority having jurisdiction, that such discontinuance curtailment,
interruption or reduction is:

of an employee, contractor or agent of EWSI that is grossly negligent or an
intentional tort.
(d)
Either EWSI or the City, or both of them jointly, may at any time issue an Order
directing all Customers to cease or restrict use of the Sewerage System in the
manner and for the period of time specified in the Order, and may cause such
Order to be publicly disseminated via print or electronic media or by posting on
the websites of EWSI or the City. A Customer is deemed to have received notice
of such Order and to be aware of its content 24 hours after it is publicly
disseminated, or at such sooner time as a copy of the Order is delivered to the
Customer's service address as shown in the Customer's account by an employee,
agent or other representative of EWSI or of the City.

2.0
Routine Adjustments
Each year, the following factors or adjustments will be used to determine appropriate adjustments to
the variable rate charges, the fixed monthly charges, the service fees and charges and the wastewater
overstrength surcharges payable for Wastewater Collection Services and Wastewater Treatment
Services:
a)
Inflation Factor;
b)
Efficiency Factor;
c)
Special Rate Adjustments.
The calculation and application of these factors or adjustments are described in subsections 2.1 to 2.4
below.
2.1
Inflation Factor
The fixed and variable charges and the service fees and charges for Wastewater Collection Services
will be subject to an annual adjustment based upon a forecast of the rate of inflation supported by the
Conference Board of Canada's forecast inflation for the upcoming year. For the purposes of this
adjustment calculation, "inflation" will be determined on the basis of two components:
a)
a Consumer Price Index ("CPI") component, weighted at 40%, based on the annual
Conference Board of Canada's forecast for Statistics Canada Table: 18-10-0005-01
(formerly CANSIM 326-0021) -- CPI, annual average, not seasonally adjusted, 2013
Basket, 2002 = 100, Alberta, All Items; and
b)
a Labour Cost component, based on the annual Conference Board of Canada's
forecast for Statistics Canada Table: 14-10-0209-01 (formerly CANSIM 281-0035),
weighted at 60%.
The fixed monthly charge, variable rate charges, wastewater overstrength surcharges and wastewater
additional overstrength surcharges for Wastewater Treatment Services will be subject to an annual
adjustment based upon a forecast of the rate of inflation supported by the Conference Board of
Canada's forecast inflation for the upcoming year. For the purposes of this adjustment calculation,
"inflation" will be determined on the basis of two components:
a)
a Consumer Price Index ("CPI") component, weighted at 65%, based on the annual
Conference Board of Canada's forecast for Statistics Canada Table: 18-10-0005-01
(formerly CANSIM 326-0021) -- CPI, annual average, not seasonally adjusted, 2013
Basket, 2002 = 100, Alberta, All Items; and
Wastewater Services Bylaw No. 20865
Page 3 of 43
Schedule 3
Performance-Based Sanitary, Stormwater and Wastewater Treatment Rates
b)
a Labour Cost component, based on the annual Conference Board of Canada's
forecast for Statistics Canada Table: 14-10-0209-01 (formerly CANSIM 281-0035),
weighted at 35%.
Once the calendar year is complete and the actual rate of inflation is known, the charges for the
subsequent year will include an adjustment to correct for the difference between the forecast and
actual rate of inflation for the calendar year. As the index utilized for the actual Labour Cost
component may not be available for the complete calendar year, the consecutive 12 month period for
which the index utilized for the Labour Cost component is most recently available is used as a
substitute for the calendar year for purposes of the Labour Cost component inflation adjustment.
Both CPI and the Labour Cost components are available and verifiable:
1.
The actual CPI component for a given year will be the change in the CPI for Alberta. This
measure is identified as the annual growth in Consumer Price Index (CPI): Statistics Canada
Table: 18-10-0005-01 (formerly CANSIM 326-0021) -- CPI, annual average, not seasonally
adjusted, 2013 Basket, 2002 = 100, Alberta, All Items. Any publication issued by Statistics
Canada which is intended to replace, supersede or otherwise revise this measure will be used
in substitution for it, in performing the inflation calculation.
2.
The actual labour cost component for a given year will be the annual growth in Average
Hourly Earnings (AHE) for salaried employees (paid a fixed salary), including overtime,
unadjusted for seasonal variation for selected industries classified using the North American
Industry Classification System (NAICS), for Alberta, Industrial Aggregate (excluding
unclassified businesses), based on the monthly Statistics Canada Table: 14-10-0209-01
(formerly CANSIM 281-0035). The annual growth in the AHE will be calculated based on
the year-over-year percentage change from the AHE in the preceding year to the AHE in the
given year, where:
AHE in the given year is the average of the most recent twelve consecutive months
of Table: 14-10-0209-01 (formerly CANSIM 281-0035) available when EWSI
finalizes its annual rate application for submission to the City Manager on or before
March 1; and
AHE in the preceding year is the average of the preceding twelve consecutive
months of Table: 14-10-0209-01 (formerly CANSIM 281-0035).
Any publication issued by Statistics Canada which is intended to replace, supersede or
otherwise revise this measure will be used in substitution for it, in performing the inflation
calculation.
As an exception to the inflation adjustment factor, if the rate of inflation (calculated in
accordance with this section) is 1.75% or lower, EWSI may prepare a financial plan to
Wastewater Services Bylaw No. 20865
Page 4 of 43
Schedule 3
Performance-Based Sanitary, Stormwater and Wastewater Treatment Rates
demonstrate the need for a unit rate increase other than 1.5%. The inflation rate in the
financial plan will be a surrogate for the value of ID.
As a further exception to the inflation adjustment factor, if the rate of inflation is greater than
5.0%, EWSI may prepare a financial plan demonstrating the appropriateness of a unit rate
increase less than the rate of inflation minus 0.25%. The inflation rate in the plan will be a
surrogate for the value of ID.
2.2
Efficiency Factor
The Efficiency Factor for the 2025-2027 PBR term for Wastewater Treatment fixed monthly charges
and variable charges, wastewater overstrength surcharges and wastewater additional overstrength
surcharges shall be 0.25%.
The Efficiency Factor for the 2025-2027 PBR term for Sanitary Utility fixed monthly charges,
Sanitary Utility variable charges and Stormwater Utility rates shall be 0.50%.
2.3
Special Rate Adjustments for Wastewater Collection Services and Wastewater Treatment Services
2.3.1
Special Rate Adjustments for Re-Basing -- Wastewater Collection Services
In each of the years 2025, 2026 and 2027 (affecting sanitary and stormwater utility rates and
Fixed Monthly Charges payable by Customers for the time periods April 1, 2025- March 31,
2026, April 1, 2026 to March 31, 2027, April 1, 2027 -- December 31, 2027), Special Rate
Adjustments for Re-Basing for Wastewater Collection Services will be added to the Sanitary
Utility Fixed Monthly Charges, the Sanitary Utility Variable Rates and the Stormwater Utility
Rate in Schedule 1, Part I: Sanitary Utility Rates and Part II: Stormwater Utility Rates. These
Special Rate Adjustments for Re-Basing are required to recover the difference between
EWSI's revenue requirement forecast for the 2025-2027 PBR term and the revenue that
would be realized if annual rate increases were limited to PBR inflation.
The Special Rate Adjustments for Re-Basing for Wastewater Collection Services will be
applied in respect of 2025, 2026 and 2027 Sanitary and Stormwater rates after the Inflation
and Efficiency factors have been calculated and applied for those years, and are in addition
to any Non-Routine Adjustments applicable to those years. Each year, after the Special Rate
Adjustments for Re-Basing for Wastewater Collection Services have been factored into the
2025, 2026 and 2027 rates and charges, these adjustments will continue to form part of the
basic Sanitary Utility Variable Rates, the Sanitary Utility Fixed Monthly Charges and the
Stormwater Utility rate in all subsequent years, to which the annual Routine Adjustment
Factors set out in subsections 2.1 and 2.2 above will be applied.
The Special Rate Adjustments for Re-Basing for Sanitary and Stormwater Services applied
to the Sanitary Utility Fixed Monthly Charges, the Sanitary Utility Variable Rates and the
Stormwater Utility Rate for the years 2025, 2026 and 2027 are as follows:

Sanitary Sewer Trunk Charges
Applicable
To all owners of a premises abutting an EWSI or City right-of-way in which
there is a sanitary or combined sewer.
Rate:
The sanitary sewer trunk charge shall be levied:
When
a
development
permit
is
issued
for development,
redevelopment, or renovation on the premises; or
-
If no development permit is required, when a building permit is issued
for development, redevelopment, or renovation on the premises; or
When an application is made for sewer service to the premises.
For the purpose of calculating the sanitary sewer trunk charge, "dwelling" and "secondary suite",
as well as reference to "use classes", have the same meaning as defined by the City of Edmonton
Zoning Bylaw; Bylaw 20001, as amended.
Sanitary sewer trunk charges are set out below:
For development, redevelopment, or renovation of premises for residential use classes:
Dwelling
20XX Fee
1 -- 2 dwelling units, excluding secondary suites
$ X
2 dwelling units where one unit is a secondary suite
$ X
3 or more dwelling units
$ X
Commercial
$ X.
Industrial
$ X
Institutional
$ X
*Sanitary sewer trunk charges for 2025-2027 shall be adjusted in accordance with an adjustment
notice provided by the city of Edmonton, as applicable.
Notwithstanding the above, if a sanitary sewer trunk charge is levied on a premises as a result of
the redevelopment or renovation of the premises, the sanitary sewer trunk charge will be calculated
using the following formula:
sanitary sewer trunk charge = A -- B
A is:
The sanitary sewer trunk charge that would have been levied based
on the above fees;
Wastewater Collection Services Bylaw 20865
Page 9 of 19
Schedule 4
Rate Sheet 4
B is:
The sanitary sewer trunk charge previously levied and paid for the
premises prior to the redevelopment or renovation on the premises; or
If the redevelopment or renovation of the premises is for residential
use classes, then the sanitary sewer trunk charge that would have
been paid had a sanitary sewer trunk charge been levied with respect
to the development that existed on the premises prior to the date of
the redevelopment or renovation.
If the result is a negative figure, the sanitary sewer trunk charge will be
deemed to be $0.
Effective Dates
These rates effective [select applicable date: April 1, 2025 to March 31,
