2 1.0 WASTEWATER FACILITIES 1.1 Langdon WWTP The WWTP is a mechanical Sequential Batch Reactor (SBR) treatment plant with UV disinfection. The plant is currently ongoing Stage 1A upgrades and upon completion will have a design capacity to treat a maximum of 5,300 m 3 /day. The capacity of the WWTP is de-rated to an effective average day flow capacity of 3,710 m 3 /day (equivalent population of 10,850). This de-rated flow capacity is based on excessive inflow/infiltration (I/I) and Alberta Environment and Park s (AEP) rule of thumb that when the average WWTP influent flows are at 70% of plant capacity, then upgrades should be planned. Treated effluent from the WWTP discharges into Weed Lake. RVC staff has indicated that they have had an assessment completed verifying that Weed Lake has enough carrying capacity to accept treated effluent at the average day target capacity of 8,000 m 3 /day. No costs have been assigned to any improvements within or downstream of Weed Lake. The average day flow at the Langdon WWTP in 2017 was 2,859 m 3 /day. The total committed flow for all developments that have paid levies is 3,845 m 3 /day, based on information provided by RVC. The proposed upgrades to the WWTP to meet the Target Capacity (average day flow of 8,000 m 3 /day) are assumed to be completed in three stages as per the Langdon Wastewater Treatment Plant Stages 1B & 2 Expansion Preliminary Design Report (Draft): Review of Probable Construction Cost Estimates prepared by AMEC Environmental & Infrastructure dated June 15, 2015 (AMEC 2015) 2 and as per the from AMEC (AMEC 2016) 3. The first stage of upgrades (Stage 1A) is ongoing and will be complete this year. The next two stages of upgrades are as follows: o Stage 1B: Increase capacity by 2,000 m 3 /day (to total plant capacity of 7,300 m 3 /day, de-rated to an effective 5,100 m 3 /day capacity, or an equivalent population of 14,940). Convert the ASBR 3 to Continuous Flow, Constant Level SCR (CSBR) with full BNR treatment capacity. This includes constructing two new decant cells with a combined total volume of 2,000 m 3. Add Anoxic and Anaerobic Mixed Cells for optimized BNR treatment. o Stage 2: Increase capacity by up to 4,200 m 3 /day (to total plant capacity of up to 11,500 m 3 /day, de-rated to an effective 8,000 m 3 /day capacity, or an equivalent population of 23,500). Construct new train (CSBR 4) of 4,200 m 3 /day capacity. Construct new blower building to house 2 new blowers. Repurpose the existing SBRs 1 & 2 to provide Aerobic Digestion if considered beneficial for RVC optimized sludge management. 2 AMEC 2015; Rocky View County Langdon Wastewater Treatment Plant Stages 1B &2 Expansion Preliminary Design Report (Draft), prepared for Rocky View County by AMEC Environmental & Infrastructure; Calgary, Alberta; June 15, AMEC 2016; Langdon Wastewater Treatment Plant Stages 1B &2 Expansion Preliminary Design Report (Draft): Review of Probable Construction Cost Estimates; prepared for Rocky View County by AMEC Environmental & Infrastructure; Calgary, Alberta; December 28,

3 The current outstanding recoverable for the Langdon WWTP is $19,082, (based on information provided by RVC). This recoverable amount includes the cost for the Stage 1A upgrades that are currently taking place. Opinion of probable cost (includes engineering, contingencies, no GST) for upgrades to Target Capacity for the Langdon WWTP are based on the AMEC Report (AMEC 2015) and (AMEC 2016) using 25% contingency: o Stage 1B: $ 6.38 M o Stage 2: $ 7.97 M Total $14.35 M 1.2 East Rocky View Wastewater Transmission Main (ERVWWTM) and Lift Stations The ERVWWTM complete with three lift stations convey wastewater from the Balzac commercial development lands to the Langdon WWTP. The approximate 2016 (measured) average day flows and peak wet weather flows for each lift station are summarized in Table 1: Lift Station Balzac LS#1 Conrich LS#2 Chestermere LS#3 Table 1: 2016 Lift Station Flows Existing Average Day Flow [1] 810 m 3 /day (9.4 L/s) 866 m 3 /day (10.0 L/s) 1,281 m 3 /day (14.8 L/s) Existing Peak Wet Weather Flow [2] Equivalent Population [3] 42 L/s 2, L/s 2, L/s 3,745 [1] From RVC monthly flow records [2] Wet Weather Flow estimated using Harmon s Peaking Factor and Inflow/infiltration allowance: 0.05 L/s/ha (estimated from 2012 flow records). [3] Equivalent Population based on 342 L/c/d Wastewater Flow. The lift stations each have two pumps with the capability to add two more pumps for a total of four pumps at full capacity. The lift station wet weather flow capacities are taken from the Sim-Flow ERRWWTM Capacity Overview letter report (Sim-Flow 2010) 4 and summarized in Table 2. The average day flow capacity is updated from the 2013 Levy Report (MPE 2013) estimated based on Harmon s Peaking factor and an inflow/infiltration allowance of 0.05 L/s/ha (calculated from the 2012 flow records). 4 Sim-Flow 2010; ERRWWTM Capacity Overview; letter report prepared for Rocky View County by Sim- Flow Systems Inc.; Langdon, Alberta; March 12,

[3] Equivalent Population based on 342 L/c/d Wastewater Flow. The ERVWWTM is a 600mm diameter pipe and is approximately 54 km long. This report assumes that the ERVWWTM has been designed to handle the wastewater for the flows at full design capacity of the lift stations. For this level of study this assumption is reasonable, but a more detailed analysis is required to confirm in the future. The projected peak wet weather flows to the lift stations when the average day flow is 8,000 m 3 /day (at Chestermere LS#3) are estimated in Table 3.

[2] Equivalent Population based on 342 L/c/d Wastewater Flow. To meet the Target Capacity (average day flow of 8,000 m 3 /day), the proposed upgrades to the lift stations are assumed as follows: o Balzac LS#1: Add one additional pump, o Conrich LS#2: Add one additional pump, o Chestermere LS#3: Add two additional pumps. The current outstanding recoverable for the lift stations and transmission line is $36,362, (based on information from RVC). The total committed flow for all developments that have paid levies is assumed to be 2,365 m 3 /day. RVC is still working on confirming the committed capacity values. For purposes of this study, it has been assumed committed capacity is the same increase as the increase in flow from 2013 to 2017 (481 m 3 /day). Opinion of probable cost (includes engineering, contingencies, no GST) for upgrades to Target Capacity for the Regional Wastewater Transmission Main and Lift Stations: o Transmission Main nil

5 o Balzac LS#1 $0.40 M o Conrich LS#2 $0.20 M o Chestermere LS#3 $1.04 M Total $1.64 M 1.3 Langdon Wastewater Utilities The existing system consists of three lift stations and forcemains to the Langdon WWTP. The three lift stations each have a separate catchment area, and each area will have a separate off-site levy, as follows: o Area 1: West Lift Station Catchment Area o Area 2: Industrial Lift Station Catchment Area o Area 3: Boulder Creek Lift Station Catchment Area The approximate current (measured) average day flows and peak wet weather flows for each lift station are as follows: Table 4: Current Langdon Lift Station Flows Lift Station Existing Average Day Flow [1] 5 Equivalent Population [2] Area 1: West LS 778 m 3 /day 2,275 Area 2: Industrial LS 230 m 3 /day 670 Area 3: Boulder Creek LS 231 m 3 /day 675 [1] Based on information from RVC. [2] Equivalent Population based on 342 L/c/d Wastewater Flow. The lift stations each have two pumps with the capability to add one more pump for a total of three pumps in each lift station at full capacity. The lift station capacities are summarized in Table 5.

Langdon Boulder Creek Lift Station Pre-Design Report and the September 29, 2003 Sim-Flow Systems Inc. Infrastructure Study Update 2003 Report. [2] Equivalent Population based on 342 L/c/d Wastewater Flow. The proposed upgrades to the Lift Stations are as follows: o Addition of one pump to each of the three lift stations The current outstanding recoverable for the Langdon Wastewater Utilities is $2,910, (based on information from RVC. Opinion of probable cost (includes engineering, contingencies, no GST) for upgrades to the Lift Stations: o Area 1: West Lift Station $0.15M

6 o Area 2: Industrial Lift Station $0.15M o Area 3: Boulder Creek Lift Station $0.15M Total: $0.45M 1.4 Dalroy to Langdon Regional Lift Station and Wastewater Transmission Main The existing system consists of a forcemain from the Wheatland County Subdivision (at Lyalta in Wheatland County) to the Dalroy Transfer Station. The wastewater is collected and stored until septic hauling trucks can transport the wastewater from the Transfer Station to an approved treatment facility. The Dalroy Transfer Station has a large holding tank with twin cells, each with 400 m 3 storage capacity (total 800 m 3 storage). One cell is normally used as a holding tank and the other only for emergency overflow. The Transfer Station was constructed in as a temporary arrangement to accommodate anticipated wastewater flows from the Phase 1 Wheatland County development of 184 houses. The average day wastewater flow for this Phase 1 development is estimated at 244 m 3 /day. Upgrades will be undertaken whenever residential and/or commercial development requires expansion of the wastewater transmission capability. The upgrades will provide an average day capacity of 1,830 m 3 /day. The proposed upgrades to the Transfer System are as follows: o The Transfer Station will be converted into a Regional Lift Station with one of the holding o tanks serving as wet well and the other cell becoming the pump well. A 19.5 km, 450 mm diameter wastewater transmission main would be installed from the Regional Lift Station to the Langdon WWTP. The current outstanding recoverables for the Dalroy Transfer Station and forcemain is $1,676, (based on information from RVC). Opinion of probable cost (includes engineering, contingencies, no GST) for upgrades to the Transfer Station system: o Regional Lift Station and Transmission Line: $19.1M 1.5 Cochrane Lakes Wastewater Transmission Main The existing system consists of a wastewater transmission system from the Cochrane Lakes Development to convey the wastewater to the Town of Cochrane WWTP for treatment. The wastewater transmission main system was built to service 1,166 residential units (1,049 m 3 /day average day capacity) in Cochrane Lakes. Levies have been paid under the old bylaw for Phase 1 and Phase 2 Cochrane Lakes development which represents 287 residential units (average day flow of 258 m 3 /day based on existing average flow generation of 900 L/unit/day). The current outstanding recoverables for the Cochrane Lakes Wastewater Transmission Main is $1,776, (based on information from RVC). No upgrades are proposed for this system. 2.0 WATER FACILITIES 2.1 Raw Water Storage Raw water is obtained from the Western Irrigation District (WID) C Canal. The point of diversion is the WID headworks at the Bow River, Calgary. The existing raw water reservoirs are located at the Graham Creek Water Treatment Plant (WTP) at the Graham Reservoir site and consist of lift stations to pump raw water from the WID canal to a stilling basin and two aerated storage cells. Raw water is pumped from the storage cells to the WTP. Raw water storage is required during winter from October 1 to May 1 when the WID canal system is shut down (212 days). 6

7 The live storage capacity of the existing raw water storage reservoirs is 744,100 m 3. Raw storage is supplemented by using the Graham Creek Reservoir as required to achieve the 212 days of storage. The existing diversion license was obtained from the WID. The license primarily is for use in East Balzac and allows water to be diverted up to a volume of 2,920,000 m 3 annually (6,083 m 3 /day). An average design flow rate of 8,000 m 3 /day equals an annual volume of 2,482,000 m 3. Therefore, the lease agreement from the WID for additional diversion license would need to be utilized. This lease agreement is for 8,400 m 3 /day for Conrich use. The raw water storage required for off-irrigation season ( winter ) given an average daily potable water demand of 8,000 m 3 /day over 212 days is 1,6961,000 m 3. Therefore, an additional storage volume of 951,900 m 3 is required. The proposed upgrades to meet the target average day capacity (8,000 m 3 /day) of the Raw Water Reservoirs are assumed as follows: o Use existing Lift Stations 1 and 2 to feed the proposed raw water storage cells. o New stilling basin, Cell 3 and Cell 4 with a live storage volume of 951,900 m 3. o Lift station to transfer water from new cells to WTP. o Groundwater interceptor system complete with lift station and tie to existing groundwater interceptor system. o Aeration system in each cell. The opinion of probable cost includes the purchase of a quarter section of land (160 acres) in NE W4 immediately south of the existing water treatment facilities for $4.2M. Land required to construct the reservoirs is 80 acres. If RVC is able to purchase half the quarter section (80 acres), there would be a potential cost reduction of approximately $2.1M. Opinion of probable cost (includes engineering, contingencies, no GST) for upgrades to Target Capacity for the Graham Reservoir Site Raw Water Storage (including land): o Raw Water Storage: $27.4M 2.2 Treatment The existing Graham Creek WTP is located at the Graham Reservoir site and includes three DAF filtration trains, three multi-media (sand and GAC) filters, UV disinfection and chlorine injection. Treated water is stored in a 700 m 3 buried chlorine contact (CT) reservoir prior to being pumped out to the transmission system. The current maximum treatment capacity of the WTP is 5,850 m 3 /day, with an average day capacity of 3,900 m 3 /day, or an equivalent population of 10,260 (assuming a treatment plant maximum day factor of 1.5). The current average day demand from the WTP (2017) is approximately 946 m 3 /day. The upgrades to meet the target average day flow capacity (8,000 m 3 /day) are proposed to be completed in two stages: o Stage 1: Upgrades will include a doubling of the WTP building with the same treatment system as the existing WTP, but with only two additional trains added. Will have a total of five treatment trains with a capacity of 9,750 m 3 /day, and an average day flow capacity of 6,500 m 3 /day (equivalent population 17,110). o Stage 2: Upgrades will consist of adding the third train to bring the capacity to 12,000 m 3 /day (average day flow of 8,000 m 3 /day, or equivalent population of 21,000). Opinion of probable cost (includes engineering, contingencies, no GST) for upgrades to Target Capacity for the Graham Creek WTP: o Stage 1: $15.3M o Stage 2: $ 2.1M Total $17.4M 7

8 2.3 Transmission There are two existing water transmission mains from the Graham Creek WTP. A 400mm diameter line conveys water to the Balzac Reservoir (storage capacity 6,375 m 3 ) and a 300mm diameter line conveys water to the Conrich Reservoir (storage capacity 4,500 m 3 ). The design capacity of the existing transmission mains are as follows: o To Balzac Reservoir: 6,083 m 3 /day average day demand (12,166 m 3 /day max. daily demand) o To Conrich Reservoir: 2,932 m 3 /day average day demand (5,864 m 3 /day max. daily demand) For the purpose of this study, the projected flow split for the total average day flow of 8,000 m 3 /day is assumed to be 2/3 to Balzac (5,333 m 3 /day, equivalent population 14,000) and 1/3 to Conrich (2,667 m 3 /day, equivalent population 7,000) based on current growth strategies and planning. Back-up of the transmission system is required in the event that either the Balzac or the Conrich transmission main is out of service (emergency condition). It is assumed that three days of average day demand is to be available for supply to the Balzac/Conrich development in this emergency condition. Three days is established as a reasonable time to locate, repair a line break and put the system back into service. Back-up to East Balzac and Conrich can be achieved by looping the transmission main (TM) system using a 400 diameter main and providing an additional 3,000 m 3 of potable water storage at a central location. The reservoir would be located to the east of Balzac at a high point in elevation so that it would gravity feed water south to Conrich, and pump water west to Balzac. The opinion of probable cost includes the purchase of land required for the reservoir, as this land is not currently owned by the RVC. RVC has collected $1,559, of off-site levies for this backup loop as of December 31, Opinion of probable cost (includes engineering, contingencies, no GST) for upgrades to Target Capacity for the Transmission Main Loop and Small Reservoir: o TM Loop and Small Reservoir: $20.3M There will be no measureable benefit to existing development. The Back-Up Loop system will benefit future development by providing the same level of system reliability to future development that is currently provided to existing development. In the future, as more growth and development activity occur, the risk associated with service disruption increases. Risk of loss (or cost) associated with service disruption increases with future development, as both the probability of a potential loss increases and the magnitude of a potential loss increases. Historically, the existing water transmission system has a very low level of service disruption; hence a relatively low probability of disruption and associated loss. As future development occurs, there is more construction, more ties to the system, more water main length, more valves, more hydrants, more usage of the existing works, and more activity in general. This will increase the probability of disruption. Similarly, with only limited development in the area currently, the magnitude of a potential loss will also increase significantly as future development occurs. Any single disruption of the primary water transmission system will affect many more businesses and lead to higher associated direct and indirect costs. From a qualitative risk perspective, the Back-Up Loop system is considered to provide a level of risk to future development that is reasonably close to that currently held by existing development. 2.4 Pump Stations & Reservoirs There are two Pump Stations & Reservoirs: o Balzac Pump Station & Reservoir o Conrich Pump Station & Reservoir For the purpose of this study, the projected flow split for the total target average day flow of 8,000 m 3 /day is assumed to be 2/3 to Balzac (5,333 m 3 /day) and 1/3 to Conrich (2,667 m 3 /day) based on current growth strategies and planning. Balzac Pump Station & Reservoir: o Existing capacity: 6,083 m 3 /day average day demand (9,300 m 3 /day maximum day demand) o Storage capacity water reservoir: 6,375 m 3 (3,150 m 3 fire storage, 3,225 m 3 E&E storage) 8

9 o Existing Balzac Pump Station & Reservoir can handle projected average day flow of 5,333 m 3 /day, therefore no upgrades are planned Conrich Pump Station & Reservoir: o Existing capacity: 1,400 m 3 /day average day demand (2,800 m 3 /day maximum day demand) o Storage capacity water reservoir: 4,500 m 3 (3,150 m 3 fire flow, 1,350 m 3 E&E storage) o Upgrades are required to reservoir to meet the projected average day flow of 2,667 m 3 /day Conrich Reservoir Upgrade: o Storage required for average day flow of 2,932 m 3 /day (to match capacity of Conrich transmission main), maximum day demand 5,864 m 3 /day: Fire storage: 3,150 m 3 Equalization storage (25% of maximum day demand): 1,466 m 3 Emergency Storage (15% of average day demand): 440 m 3 Minimum required storage: 5,056 m 3 (minimum 556 m 3 to be added) o Storage reservoir upgrade to add 1,000 m 3 storage (total storage: 5,500 m 3 ) Opinion of probable cost (includes engineering, contingencies, no GST) for upgrades to Target Capacity for the Conrich Reservoir: o Conrich Reservoir Expansion: $2.1M 3.0 BRAGG CREEK FACILITIES The following provides background information for the development of new off-site levies for Bragg Creek Water and Wastewater Facilities, including opinions of probable cost to increase capacity of the various facilities to a target average day flow capacity of 604 m 3 /day water demand and 513 m 3 /day wastewater flow. These target capacities were provided by Rocky View County (RVC), established generally on the current capacity of the Wastewater Treatment Plant (WWTP) outfall diffuser. The WWTP outfall diffuser has a maximum day capacity of 821 m 3 /day of treated effluent (average day capacity of 513 m 3 /day assuming a maximum day factor of 1.6). 3.1 Bragg Creek WWTP The WWTP is located on the west side of the Elbow River at the north side of Bragg Creek. The WWTP receives wastewater from the Bragg Creek collection system from the east side of the Elbow River. The collection system utilizes a low pressure forcemain to convey raw sewage to the WWTP. Each residence that is tied into the system has an onsite grinder pump that pumps the sewage to a common forcemain. The treatment system includes two membrane bioreactor (MBR) treatment units with UV disinfection. Phase 1 of the WWTP was built in 2012 and has a maximum day capacity of 185 m 3 /day. Phase 2 was built in 2014 and has a maximum day capacity of 278 m 3 /day. The total maximum treatment capacity is 463 m 3 /day, with an average day capacity of 285 m 3 /day (assuming a maximum day factor of 1.62). Treated effluent from the WWTP discharges into the Elbow River. The outfall diffuser has a capacity of 821 m 3 /day of treated effluent. The 2016 average day flow at the WWTP is approximately 70 m 3 /day, with 107 lots tied into the system. The total committed average day flow for all existing developments that have paid for the WWTP is 140 m 3 /day, (based on information provided by RVC). The proposed upgrades to the WWTP to meet the target capacity (average day flow of 513 m 3 /day) will include: o Two Evoqua 50K MBR treatment systems (to total 821 m 3 /day capacity at WWTP). o A building expansion complete with additional EQ Tanks and Biofilter. There is a current outstanding recoverables to the County of $1,453, for the Bragg Creek WWTP and sanitary collection system (based on information from RVC). 9

10 Opinion of probable cost (includes engineering, contingencies, no GST) for upgrades to target capacity for the Bragg Creek WWTP: o Total $6.9M The lands benefitting from this project will be lands with new development that will have wastewater treated at the WWTP system. 3.2 Bragg Creek Water Treatment Plant (WTP) The existing Bragg Creek WTP was built in 2011 and is located at the north end of Burnside Drive. The treatment system includes two membrane treatment units, UV disinfection and chlorine injection. Potable water is stored in a 500 m 3 above ground steel reservoir prior to being pumped out to the Bragg Creek distribution system. The existing PWR does not provide fire storage. Water is also pumped from the WTP to the Lower Elkana Pumphouse where it is pumped to the Upper Elkana Reservoir and Pumphouse. The water is distributed from the Upper Elkana Pumphouse to the Elkana service area. The current maximum treatment capacity of the WTP is 500 m 3 /day, with an average day capacity of 194 m 3 /day (assuming a maximum day factor of 1.66). The 2016 average day demand from the WTP is approximately 124 m 3 /day. There are 108 lots tied in from Bragg Creek service area, and 67 tied in from the Elkana service area. The total committed average day demand for all developments that have paid for the WTP is 302 m 3 /day, (based on information provided by RVC). The upgrades to meet the target average day demand of 604 m 3 /day (MDD 1,000 m 3 /day) are proposed to be: o o Expansion of the WTP building with two additional membrane units added. Will have a total of four treatment trains with a capacity of 1,000 m 3 /day, and an average day flow capacity of 604 m 3 /day. There is a current outstanding County recoverables of $928, for the Bragg Creek WTP and distribution system (based on information from RVC). Opinion of probable cost (includes engineering, contingencies, no GST) for upgrades to Target Capacity for the Bragg Creek WTP: o Total $6.6M The lands benefitting from this project will be lands with new development that will have water supplied from the Bragg Creek WTP system. 3.3 New Potable Water Reservoir (PWR) To meet the target average day capacity of 604 m 3 /day (MDD 1,000 m 3 /day) water demand, a new potable water reservoir will need to be installed at the WTP site and will have a storage capacity of 500 m 3. The reservoir is not sized for fire storage. The volume of 500 m 3 is based on: o Fire Storage: 0 m 3 /day o Total MDD of 1,000 m 3 /day o Total storage required = 1,000 m 3 (Fire Storage + MDD as per County Fire Bylaw) o Existing PWR storage at WTP is 500 m 3 o 1,000 m m 3 = 500 m 3 storage required The daily service capacity of new PWR: 302 m 3 /day average day demand (500 m 3 /day maximum day demand assuming a maximum day factor of 1.66). Opinion of probable cost (includes engineering, contingencies, no GST) for upgrades to Target Capacity for the new PWR: o Total: $1.26M The lands benefitting from this project will be lands with new development that will have water supplied from the new PWR. 10

11 4.0 EXISTING RECOVERABLES AND OPINIONS OF PROBABLE COST SUMMARY The following tables summarize the recoverables, and the opinion of probable cost upgrades to the water and wastewater facilities in order to meet the Target Capacities.
