Water

Outdoor watering activities, such as watering lawns, are permitted two days per week. Even numbered homes can water on Tuesday and Friday. Odd numbered homes can water on Monday and Thursday. You may also hand water flowers, vegetable gardens, trees and shrubs with a container or hose with a manual trigger nozzle.

The Town of Okotoks is a recognized leader in sustainable water management. We've had a watering schedule in place since 2008 - when our population was just over 17,000. The watering schedule was made into a Water Bylaw to manage supply and demand and promote responsible sharing of a limited resource. 

The latest version of our watering schedule was approved by Council on March 25, 2024 to further increase water conservation efforts as we face the likelihood of an upcoming drought. The main changes include watering on weekdays only and reduced daily watering time by one hour. These changes help to reduce peak demand (on weekends) on our water system, while still providing enough watering hours to keep your lawn healthy. 

The watering schedule aligns with our five Water Conservation Stages outlined in the Water Bylaw, becoming increasingly cautious in order to sustain water availability for our community’s essential use (e.g. drinking, cooking, sanitation and fire suppression).

Planning to lay down new sod or seed on your property? You can apply for a Water Exemption Permit which allows for additional watering days to promote root growth establishment of new turf. The Water Exemption Permit will only be issued when the Town is in Water Conservation Stages 1-3 of the Water Bylaw. No new exemptions will be granted in Water Conservation Stages 4 or 5. 

Applications are available May 1 to October 31, when the outdoor watering schedule is in effect. Permits are processed within 1 business day at no charge. 

Please apply for the permit before installing seed or sod:

Our Water Allocation Policy ensures that sufficient water license capacity is available before approving land use for new development. The amount of water in the Sheep River is regulated by licenses issued by the Province of Alberta. The Water Allocation Policy works to prevent us from exceeding the licensing capacity of the Sheep River.

Since 2010, the Town has purchased water licenses to facilitate growth, increasing our overall water license portfolio by 45% from 2.8 million cubic meters to over 4 million cubic meters.

The Town’s Water Shortage Response Plan (WSRP) is in place to sustain water availability for our community’s essential use (e.g. drinking, cooking, sanitation and fire suppression). The plan outlines five water conservation stages that become increasingly cautious, depending on current and projected reservoir volumes, as well as taking into account a number of other considerations, including: stability of reservoir levels; lead time consideration; risk to public health and safety; environmental risk; projected license capacity; consideration of other watershed users and regional collaboration; and professional judgment, experience and standards. Changes to these levels can occur quickly—the current level is posted at the top of this page. A table outlining the specific conservation measures and enforcement for each stage of the WSRP is provided in the Town's Water Bylaw. 

Stage 1: Normal Operations

• Stage 1 encourages residents to practice responsible water use. There are no additional measures beyond following the outdoor watering schedule.
• Hand watering flowers, vegetable gardens, trees and shrubs with a container or hose with a manual trigger nozzle is permitted.

Stage 2: Enhanced Community Outreach

• Stage 2 focuses on increasing community awareness about the importance of water conservation.
• Hand watering flowers, vegetable gardens, trees and shrubs with a container or hose with a manual trigger nozzle is permitted.

Stage 3: Outdoor Watering Limited to 1 Day per Week

• Stage 3 introduces additional conservation measures on outdoor water usage to reduce water consumption. Outdoor watering activities, such as watering lawns, are limited to one day per week.
• EVEN numbered homes can water on Friday. ODD numbered homes can water on Monday.
• Hand watering flowers, vegetable gardens, trees and shrubs with a container or hose with a manual trigger nozzle is permitted.

Stage 4: Full Outdoor Water Ban

• Stage 4 signifies a significant escalation in water conservation measures. 
• Outdoor watering is prohibited.

Stage 5: Essential Use Only

• Stage 5 represents the highest level of water conservation urgency, where water resources are prioritized for essential purposes only.
• Outdoor watering is prohibited.

• Okotoks has systems and processes in place to effectively manage the water supply for our community’s essential use, and to support current development. 
• Our Water Allocation Policy ensures that sufficient water license capacity is available before approving land use for new development and works to prevent us from exceeding licensing capacity of the Sheep River.
• The amount of water in the Sheep River is regulated by licenses issued by the Province of Alberta. Since 2010, the Town has purchased water licenses to facilitate growth, increasing our overall water license portfolio by 45% from 2.8 million cubic meters to over 4 million cubic meters.
• Since 2010, our population has increased by almost 10,000 people – yet the amount of water used per person per day has significantly decreased. In fact, Okotoks is one of the lowest per-capita consumers of water in the country.

The Town of Okotoks is committed to water sustainability and living within our means. Since 2008, our community has followed an outdoor watering schedule to manage supply and demand, and promote responsible sharing of a limited resource. It's part of our DNA to conserve water and the watering schedule will not go away - even when the Supplemental Water Solution (pipeline project) is complete.

Hand watering flowers, vegetable gardens, trees and shrubs using a container or hose with a manual trigger nozzle may be done at anytime in Water Conservation Stages 1-3, or from 8 PM - 8 AM in Stage 4. Residents may apply for a water exemption permit if they are planning to lay down new sod or grow from seed.

Potable Water: Water that is suitable for human consumption (i.e. water that can be used for drinking or cooking).

Non Potable Water: Water that is not treated to drinking water standards and is not meant for human consumption.

You can apply for a Water Exemption Permit which allows for additional watering days to promote root growth establishment of new turf. The Water Exemption Permit will only be issued when the Town is in Water Conservation Stages 1-3 of the Water Bylaw. No new exemptions will be granted in Water Conservation Stages 4 or 5. 

Applications are available May 1 to October 31, when the outdoor watering schedule is in effect. Permits are processed within 1 business day at no charge.

• On hot summer days, residents more than double (and sometimes even triple) regular water consumption just by watering their lawns. As the river cannot produce double/triple capacity on those days, we are using so much water that we are emptying our reserves. That is the definition of unsustainability. By reducing consumption, we live within our means.  
• To put this into perspective, in winter our water consumption is approximately 6000-7500 ML per day. In summer 2022, peak water usage was 14,000 ML per day, while max capacity in the river is 11,500 ML (according to August 2022 stats).
• Accordingly, the Town implemented a Stage 3 Partial Outdoor Water Ban as a proactive measure to ensure we have enough water for essential use, such as drinking, cooking, sanitation and fire suppression. A Stage 3 Partial Outdoor Water Ban means residents are not permitted to water their lawns on weekends.

In Stages 1-3, the Town waters sports fields 3-4 times per week depending on field bookings, turf conditions (assessed weekly) and weather conditions. The irrigation systems are broken down into zones that run for 15 to 20 minutes per zone, between 11 p.m. - 7:30 a.m. 

In Stage 4, all non-priority sports fields irrigated with potable water will be shut down. Watering of priority sports fields will be reduced by 50% (focusing on maintaining safety). Priority fields are defined as any field that is booked several times a week and requires an increased amount of water to combat high traffic (soil compaction) and protect players' safety, as well as withstand weather conditions. These include Howard, Bill Robertson, Conrad Field, Tourmaline Field, Seaman Stadium, the Track, Dr. Morris Gibson, Big Rock, JPII, Lauden and Westmount.

In Stage 5, all sports fields that are irrigated with potable water will be shut down. Sports fields that are irrigated with non potable water will remain open, including Bill Robertson Park, Conrad Field, Laudan Park, Seaman Stadium and Tourmaline Field.

Potable Water: Water that is suitable for human consumption (i.e. water that can be used for drinking or cooking).

Non Potable Water: Water that is not treated to drinking water standards and is not meant for human consumption.

Sports fields that are irrigated with non potable water include:

• Bill Robertson Park
• Conrad Field
• Laudan Park
• Seaman Stadium
• Tourmaline Field

In Stage 4, all non-priority sports fields irrigated with potable water will be shut down. Watering of priority sports fields will be reduced by 50% (focusing on maintaining safety). Priority fields are defined as any field that is booked several times a week and requires an increased amount of water to combat high traffic (soil compaction) and protect players' safety, as well as withstand weather conditions. These include Howard, Bill Robertson, Conrad/Tourmaline, Seaman Stadium, the Track, Dr. Morris Gibson, Big Rock, JPII, Lauden and Westmount.

In Stage 5, all sports fields that are irrigated with potable water will be shut down. Sports fields that are irrigated with non potable water will remain open, including Laudan Park, Bill Robertson Park and Seaman Stadium.

These types of activities are permitted while we are in Water Conservation Stages 1 - 3. However, in Stages 4 & 5, they would not be permitted as these stages signify an escalation in water conservation measures and will will require the community's support to refrain from all non-essential outdoor water activities. Moving to Stages 4 & 5 means that the situation is severe and a water shortage is imminent unless conservation measures are implemented.

• Currently, treated (potable) drinking water is stored within three underground reservoirs with available combined volume of 19.5 ML (million liters). We have approximately 2.8 days storage during average daily demand. This can drop to 1.3 days during heavy outdoor watering in the summer months.
• The new Regional Pipeline will come with a large (raw water) reservoir and 30 days storage. What does this mean? Raw water reservoir stores untreated water (water diverted from the river) and provides enough storage volume (or redundancy) to serve Okotoks for approximately 30 days. This is important when river levels are low where our pumping volumes are reduced. It also provides redundancy during times of system maintenance etc.

Diamond Valley passed a Water Use and Conservation Bylaw in 2023. 

D'Arcy and Crystal Ridge golf courses operate independently from the municipal water system, each with its own water sources and licenses. Currently, discussions are underway between the Town and the golf courses to explore various water conservation strategies. 

These water trucks are using non-potable (untreated) water for dust control purposes.

In accordance with the Environmental Protection and Enhancement Act (EPEA), the Town of Okotoks has applied to Alberta Environment and Protected Areas for a new (renewed) EPEA approval for its wastewater system (the “Approval”). This Approval would allow the Town to continue to operate its wastewater system in accordance with Approval requirements for up to 10 more years.

The Application explains that the Okotoks wastewater system consists of a piped wastewater collection system, a wastewater treatment plant (WWTP) located at 200, 1118 North Railway Street that treats both the collected wastewater and the septage and wastewater brought to the WWTP by truck, and a treated wastewater outfall to the Sheep River in the NW ¼ 22-020-29-W4M.

The Application further explains that the two wastewater treatment trains in the WWTP use identical biological treatment and chemical assisted clarification and filtration processes to control the amount of organics, nutrients, and ammonia in the treated wastewater. Each treatment train can treat the annual average design flow of 10,000 cubic metres per day that the WWTP is designed to treat. (In 2024 the WWTP received an annual average daily flow of 6,100 cubic metres of wastewater produced by approximately 33,400 people.)

If one treatment train is not operational, the other treatment train can still control the substances as required by the Approval when wastewater flows are within the WWTP’s hydraulic capacity. A standby generator at the WWTP provides the treatment processes with the electrical power needed to treat and disinfect the wastewater during utility power interruptions.

The WWTP uses odorous gas control systems to control the release of malodorous gases from areas of the WWTP where these gases can be produced. Biosolids (sludge) produced by the wastewater treatment process is dewatered and taken to an EPEA regulated facility for treatment and disposal.

The Application explains that Okotoks proposes that the maximum concentration of ammonia in the treated wastewater release be limited to 2 mg/L between July 1 to September 30, and 5 mg/L the rest of the year. While Okotoks does not currently use treated wastewater for irrigation, the Application requests this use option remain in the Approval.

The Application confirms that Okotoks would, as required by the Approval, continue to report to AEPA the results of the Approval required monitoring that is done to confirm substance released with the treated wastewater comply with Approval limits.
