Sylvan Lake Watershed Overview
• The watershed is 106 km2 and encompasses the
run-off basin for the 42 km2 lake itself
• Sylvan lake holds 420 million cubic metres of water
at an average depth of 10.4 m
• Sources of water inflow to the lake:
• 60% of the water in the lake comes from rain
• 30% is surface run-off
• 10% underground spring fed
• Water outflow from the lake:
• 90% from evaporation
• 10% from outlet control
• Potable water AND wastewater are are hydraulically

• Sunbreaker Cove ("SBC") consists of 271 residences including summer cabins and larger modern homes
• SBC potable water supply comes from individual wells
• SBC waste water systems include both septic fields and closed pump-out tanks
• SBC potable water supply comes from individual wells
• SBC waste water systems include both septic fields and closed pump-out tanks
• Until recently, most of the homes
within the Sylvan Lake watershed have
been disposing wastewater into a
septic field or holding tanks
• Over time, the water quality of both
the lake AND the potable water supply
will suffer without a sustainable
wastewater collection system

Central Alberta Regional Wastewater (CARWW) System
• Over 12 years ago, the design and conceptual plan for the CARWW system was initiated
• The CARWW system is designed to comply with Alberta Environment's directive to prohibit continuous discharge of treated, and untreated, wastewater upstream of the City of Red Deer.
• The CARWW System design was collectively planned by many regional municipalities to address the key requirements of the system to include:

• The CARWW system is designed to comply with Alberta Environment's directive to prohibit continuous discharge of treated, and untreated, wastewater upstream of the City of Red Deer.
• The CARWW System design was collectively planned by many regional municipalities to address the key requirements of the system to include:
- To provide wastewater treatment at a single, major water treatment facility located in the City of Red Deer.
- Construction of regional collection systems including a North Leg, Central Leg, and Southern Leg.
- Include facilities to receive trucked wastewater from smaller sewage systems that cannot otherwise practically connect to the CARWW system.
- Most importantly, this system is designed to protect the water quality for current residents, and support the continued growth and economic expansion in the region.
The CARWW System will gather regional wastewater for treatment in Red Deer

Sylvan Lake Regional Wastewater Commission (SLRWWC)
• Created in 2010 to manage the construction and operation of the regional wastewater handling system
• Includes representative of each of the 8 municipal jurisdictions surrounding the lake (County of Lacombe and Red
Deer, Sylvan Lake and the five summer villages)
• SBC’s representative on the Commission is Deputy Mayor Teresa Beets
• To-date, collection systems have been installed in Jarvis Bay, Norglenwold and Blissful Beach.

• On May 29, 2017, the SLRWWC received a funding grant of $37.1 m (90% of the total cost) to build the central line from the Town of Sylvan lake to the Red Deer treatment plant • This grant marks a significant milestone for all lake residents, and eliminated the current bottleneck at the Sylvan lake treatment lagoons. • Engineering contract will be awarded on June 26, 2017 and targeted start-up is for Q3-218 |

• Existing MSI grants and capital cash reserves account of 64% of the funding requirements
• Subject to Minister Approval, $1.0 m or 30% of the costs will be from a debenture which will be financed over 15 or 25 years by a local improvement tax
What is the Local Improvement Tax, and how will it work?
• The business plan calls for a Local Improvement Tax (LIT) under the statutory authority of the Municipal Government Act
• Subject to Minister approval, Sunbreaker will borrow $1,007,135 from the Alberta Capital Finance Authority and finance the costs of the debenture over 15 or 25 years
• To pay for the debenture, the LIT will be paid by property owners where costs are shared equally by all 271 residences/lots within the community
What is the estimated cost of the debenture financing per household?

Wastewater Management Project - Total Costs
Property owners can expect to see the following projected costs to pay for the Wastewater system
- Homeowners will be responsible for the installation and construction costs of the tie-ins on their property. Past projects have averaged $6,000 - $8,000/house depending on length of pipe required, etc.
- Cost of the Local Improvement Tax
• One-time cost of roughly $3,700
• Or an annual cost of $332 for 15 years, or $237 for 25 years - Operating expenses are recovered based on a utility rate model applied equally to each property. Costs forecast to increase in 2020 to reflect cost of transportation and treatment at the Red Deer treatment plant.
Sunbreaker Cove - Waste Water Project Timeline
Sunbreaker is targeting commissioning and start-up of the system September 2019.
• The execution plan of the overall project include the following key assumptions:
• The execution plan of the overall project include the following key assumptions:
- Concurrent construction of the SBC gathering system, Blissful Lift Station and SLRWWC lateral to begin in May 2019 and be completed over the summer.
- SBC will not commence field construction until the SLRWWC has commenced construction on the North Leg lateral from Birchcliff, and completion of the (proposed) Blissful Beach lifting station
- In order to meed this target, the SLRWWC will need to kick-off engineering design, cost estimates, business plan, and funding application in July 2017.
• Phase 1 - SBC
• SCB will kick-off debt limit request and blyaw once the SLRWWC has triggered the North Lateral project.
• Phase 2 - SLRWWC
• Preliminary engineering design and cost estimates for the commission facilities should be started in July 2017.
• This will allow adequate timing to ensure all funding and approvals are in place no later than September 2018.
• Phase 3/4 - Construction
• Combining the construction of both segments, SBC and SLRWWC may benefit from economy of scale in accessing services and materials.
• However, in order to achieve the September 2019 start-up, approvals from both parties will be required by October 2018.

Scenes from Birchcliff...
• All lines are drilled to minimize surface disturbance and lower costs
|
• Flagging to show where lines and connections will go
|
|
• Mainline pipe is 4" HDPE spooled pipe
• Manways are used for access to isolation valves and flushout points |
