Treatment
Water Treatment Processes
Water treatment removes natural and man-made contaminants
from the source water so that it is safe and pleasant to drink.
The treatment process from a surface water source (like a river
or lake) differs from treatment for groundwater (drawn from
an aquifer).
Monitoring Requirements
SaskWater undertakes water quality testing as required by
The Waterworks and Sewage Works Regulations, 2015 and by
operating permits for our water treatment plants and
distribution systems.
Surface Water
Generally, surface water treatment involves either conventional
treatment, which consists of screening to remove debris,
coagulation-flocculation, clarification or sedimentation, filtration,
and disinfection; or membrane treatment, which consists of
screening to remove debris, reverse osmosis membrane filtration,
and disinfection to remove physical, chemical, microbial and other
contaminants from the water.
• assess and ensure the safety of the water for our customers
SaskWater monitors water quality to:
• assess the need for any process adjustments
• determine quality trends and identify potential concerns
We employ more than 60 provincially certified operators who
monitor and maintain the quality of water from the initial source
to the final point of delivery.
Our highly trained, dedicated operators, technicians, technologists
and professional engineers keep abreast of technological changes,
water quality, and any upgrading needs of our waterworks
systems to meet ever-changing water quality standards and
monitoring requirements.
Our treatment plants in Melfort, Wakaw, Gravelbourg, Edenwold
and Elbow use these types of processes.
Groundwater
For groundwater, the treatment process generally consists of
oxidation of iron, manganese and other minerals with aeration
and/or other processes followed by detention, filtration and
disinfection.
SaskWater also monitors most of our facilities and customer
facilities remotely. We have remote monitoring equipment
installed in 55 locations, which we either own or operate,
allowing continuous facility surveillance.
Our treatment plants in Pierceland, White City and Cupar use
groundwater sources with this kind of treatment process.
We monitor key water quality parameters, equipment operation
and water levels, pressures and flows.

Not required to test (as per permit).
Due to be sampled again in 2016.
Deviation from Water Security Agency Permit to
Operate requirements.
1. Regulatory Limits
Total Coliform: zero organisms detectable per 100 mL
E. coli: zero organisms detectable per 100 mL
Background Bacteria: less than 200 organisms
per 100 mL
Any organisms detected over these limits will result
in one positive for that sample.
2. Chlorine residuals in the distribution system must
be either 0.1 mg/L free or 0.5 mg/L total.
3. Additional testing carried out by SaskWater but not
required by the permit.
4. Bacteriological samples not taken the week of
August 3, 2015. The EPO was notified.
12
5.Samples were not submitted the weeks of July 6 and
July 13 due to suspension of postal service caused
by forest fire. EPO was notified and two “other”
samples were taken on July 20 and two on July 21 to
confirm water quality after services resumed.
6.Low chlorine residual caused by process equipment
malfunction. The EPO was notified.
7.One incidence of low chlorine residual from July 3 to
July 4 following a power outage. The EPO was
notified and a PDWA was issued.
8.One incidence of low chlorine residual on
December 9, 2015. Field staff was on site, notified
EPO and residual climbed above 0.10 mg/L
within 5 minutes.
9.June 29, 2015, sample was not taken due to leak
repair.
10. Aesthetic objectives are exceeded, but all regulatory
requirements are met.
Transmission
In addition to water treatment facilities, SaskWater also owns and provides certified operation and maintenance for potable water
transmission systems. There are no treatment facilities on any of these transmission systems.
Monitoring Requirements
Depending on the population, each potable water transmission system must be monitored according to the Water Security Agency’s (WSA)
Municipal Drinking Quality Monitoring Guidelines. Permit requirements for a specific waterworks may require more sampling than outlined
in WSA’s guidelines.
The following table summarizes the water quality monitoring and testing requirements for bacteriological, chlorine residuals, turbidity,
chemical and health and toxicity parameters for each of our owned and COM facilities.

Precautionary Drinking Water Advisory (PDWA)
An advisory issued under the authority of Subsection 36(1) of
The Environmental Management and Protection Act, 2010 by Water
Security Agency Field Offices (WSAFO) when the WSAFO determines
that there is a possibility that drinking water quality concerns exist
but immediate public health threats have not been identified. As an
example, it is standard protocol to issue a PDWA when a water main
is depressurized to undertake repairs.
Key Drinking Water Parameters and Effects
Emergency Boil Water Orders
As the regulator for water quality, the Water Security Agency
determines standards which are legally enforceable requirements for
drinking water quality as per The Waterworks and Sewage Works
Regulations, 2015. In general, standards are mandatory health
parameters for systems that supply water for human consumptive
use. The WSA also determines water quality aesthetic objectives
which apply to certain characteristics
of or substances found in water for human consumptive or
hygienic use.
There were no emergency boil water orders (EBWO) issued on any
SaskWater owned or operated facilities in 2015.
Precautionary Drinking Water Advisories
A Precautionary Drinking Water Advisory (PDWA) is issued when
drinking water quality concerns exist but immediate public health
threats have not been identified. They are commonly issued as a
result of power outages or maintenance that may result in
depressurization of the distribution system.
SaskWater’s governing standards for potable water quality direct us
to meet or exceed the water quality parameters set by the province
of Saskatchewan.
There were twelve (12) PDWAs issued on SaskWater owned potable
water systems in 2015:
Additional information on water quality, standards and aesthetic
objectives can be found here:
• Saskatoon Potable Water Supply System – East had a PDWA on
January 23rd and May 20th due to new water main connections
that resulted in a system depressurization.
Health Canada – Canadian Drinking Water Quality Guidelines
http://www.hc-sc.gc.ca/ewh-semt/water-eau/drink-potab/
guide/index-eng.php
• Saskatoon Potable Water Supply System – North had a PDWA on
March 1st and March 10th due to depressurization caused by a
water main repair.
SaskH2O – My Drinking Water
http://www.saskh2o.ca/MyDrinkingWater.asp
• Saskatoon Potable Water Supply System – West had a PDWA on
November 2nd due to depressurization caused by planned system
maintenance for a new piping tie-in.
WaterTrax – Parameters Portal (free registration required)
http://www.watertrax.com/water-wastewater-industry-knowledge/
parameters.aspx
• Buffalo Pound Potable Water Supply System – East had a PDWA
on May 6th due to a planned depressurization of the water
distribution system due to necessary maintenance on the City of
Regina water transmission main.
19
There is an ongoing PDWA issued by the Water Security Agency in
2008 on SaskWater’s Saskatoon Non-Potable Water Supply System
– East and West. This is a situation where the Water Security Agency
has decided that this system falls under The Environmental
Management and Protection Act, 2002 and The Waterworks and
Sewage Works Regulations, 2015. This is a non-potable water supply
system developed to supply industrial customers; however,
household users are also supplied and the water is unsuitable for
drinking unless treated. All residential users on the east system have
since confirmed that the non-potable water system is no longer
connected to their domestic water system. The majority of these
users are now being supplied by the Dundurn Rural Water Utility. No
further ongoing PDWA will be required for the east non-potable
water system; however the PDWA has not yet been rescinded by the
WSA. An alternative potable water source for the west system
residential users has yet to be developed and water users have until
December 31, 2016, to find alternate sources.
• Buffalo Pound Potable Water Supply System – North had a PDWA
on May 6th due to a planned system depressurization to facilitate
tie-in of new water mains, on October 20th due to a
depressurization of the water distribution system, and on
December 11th due to a system-wide depressurization.
• Buffalo Pound Water Supply System – West had a PDWA on
October 20th due to a depressurization of the water distribution
system and on December 11th due to a system wide
depressurization.
• The Wakaw-Humboldt Regional Water Supply System had a PDWA
issued March 6th due to a depressurization caused by a water
main repair.
Where SaskWater provides operation and maintenance services to
community or rural pipeline association-owned systems, there were
thirteen (13) PDWAs issued in 2015:
• The Interlake Regional Water Board had three PDWAs: one on
January 19th due to a depressurization in the distribution system
caused by a line break and repair, and one each on June 18th and
July 20th due to depressurization caused by a power outage.
• The Village of Halbrite had a PDWA on February 5th due to
depressurization due to maintenance, and one on March 26th due
to possible reservoir contamination.
• The Jackfish Lake West Water Utility had PDWAs issued on January
24th, June 17th and July 6th due to a depressurization caused by a
power outage.
• The North Central Rural Pipeline Association had a PDWA March
6th due to a depressurization caused by a water main repair on
the Wakaw-Humboldt Regional Water Supply System.
• The Northern Village of Air Ronge had a PDWA on June 29th due to
a depressurization of the distribution system due to a water main
repair, and on October 1st, October 22nd and October 23rd due to
depressurizations required for fire hydrant repair.
There were some instances of SaskWater potable customers having
PDWAs issued on their own distribution systems in 2015. Other than
the instances noted above, all of these advisories were due to issues
with the customers’ facilities and not due to the water supplied
by SaskWater.
There were some instances of SaskWater non-potable water
customers having PDWAs issued on customer-owned treatment and
distribution systems in 2015. In these instances, customers are aware
that the water SaskWater supplies is non-potable, and if they wish to
use non-potable water for domestic purposes, the customers are
responsible for providing their own water treatment.
