Resort Infrastructure Servicing: Camp Ramah (Skeleton Lake, District of Muskoka, Township of Muskoka Lakes)

Wastewater Treatment System

Camp Ramah in Canada is a summer camp for approximately 600 children, located on Skeleton Lake in the Township of Muskoka Lakes, District Municipality of Muskoka.  Since 1994, CCTA has provided engineering design and contract administration and inspection services to Camp Ramah for the following infrastructure improvements:

Features

• A 9,800 cu m facultative sewage lagoon with fine-bubble aeration and a discharge weir to the Skeleton River, and new sanitary force mains from the sewage pumping stations;
• Replacement of three sewage pumping stations;
• A raw water intake pipe and fire hydrant system for fire-fighting purposes;
• A 1,088 m3/day drinking water treatment system, including raw water pumping station, primary and secondary chlorine disinfection, chlorine contact pipe, coagulant addition, multi-media pressure filters, cartridge filters, and all related instrumentation, and improvements to the water distribution system;
• On-going operational assistance and advice related to the sanitary sewage and drinking water systems, including the preparation of annual performance reports.

Wastewater Treatment Plant: Lagoon City (Township of Ramara)

CCTA, as the Township of Ramara’s engineers, has been providing ongoing technical assistance and design services to upgrade and expand the Lagoon City sewage treatment plant, an extended aeration sewage treatment facility with effluent discharge to Lake Simcoe.

Following a thorough evaluation of the sewage treatment plant, CCTA recommended upgrades for process optimization to improve operation and performance and to meet current day safety standards.  CCTA designed, amongst other upgrades, a septage receiving facility with odour control and an improved sludge management facility.  A staged upgrading program was developed focused on the long-term objectives for the plant.

CCTA designed the expansion of the sewage treatment plant from a capacity of 1,713 cu m/day to 2,273 cu m/day, to accommodate the servicing of the village of Brechin and future growth.  The sewage treatment plant expansion works comprised the addition of a secondary clarifier, UV disinfection equipment in a building expansion, a biosolids aerobic digester and storage tank, and a new blower building.  The $3 million project was completed in 2008.

Wastewater Collection and Pumping Systems: Village of Brechin

The need for sewage servicing in the Village of Brechin has been identified since municipal water was implemented in 1978. Recent septic system surveys documented a significant number of septic systems are not functional, and there is evidence of sewage contamination in storm sewers and ditches. This situation is unacceptable because of health risks, and environmental contamination of Lake Simcoe.

A long-term sewage servicing plan was developed for Brechin and the adjacent communities of Lagoon City and the lakeshore areas. The first phase of the plan addresses the need to sewer Brechin and thus achieve immediate public health and environmental benefits.

CCTA directed the project through the Municipal Class EA process, completed the preliminary and final design of the collection and pumping systems, obtained all approvals, prepared contract documents and provided construction administration and inspection activities.

Features

• Gravity sewers throughout Brechin (4.2 km)
• Three lift stations
• Forcemain to the existing Lagoon City STP (5 km)

Construction was completed in 2008 with a final project cost of approximately $10 million.

Wastewater Treatment Plant: Town of Kapuskasing

CCTA completed the energy audit and assessment of the Kapuskasing wastewater treatment plant to establish the upgrades required to improve operation and energy efficiency, reduce sewage bypasses, and implement health and safety measures. The assessment included review of options for: effluent disinfection (UV versus chlorination / dechlorination) taking into consideration building mechanical and electrical implications; improving the biological treatment process operation and control; improving biosolids management and storage; replacing the emergency generator, transformer and primary switch; providing plant controls and SCADA; and upgrading the heating and ventilation systems and controls.   The design of the process, mechanical and electrical upgrades is ongoing and the $7 million project will be constructed in 2010.

Potable Water Supply: Town of Innisfil

Water Supply, Treatment and Distribution: Town of Innisfil

From start to finish, CCTA designed and developed the Town’s new lake-based water works at Alcona.  Under CCTA’s management, this $23 million project met tight timelines and was completed within the original capital budget.  CCTA subsequently designed the expansion of the water treatment plant to a capacity of 28,400 cu m/day.  Construction of the WTP expansion was completed in 2008.

Features

• Intake from Lake Simcoe
• Low-lift pumping station
• High rate direct filtration water treatment plant with GAC adsorption and chloramination
• Trunk mains and distribution system
• Water storage reservoir

Alcona to Bradford Water Transmission Main

CCTA completed the final design of a 26 km water transmission main between the Alcona Reservoir in Innisfil and the Bradford West Gwillimbury distribution system.  The works including a booster station and a monitoring station, were constructed in 2007 at a construction value of $18 million.

Features

• Connection to existing Alcona reservoir
• Connection and integration with new reservoir in Bradford West Gwillimbury
• A monitoring/metering station at the boundary between the municipalities
• Temporary and permanent booster pumping stations
• Provision for future take off points to other growth areas along the route

Potable Water Distribution: Township of Severn

The water distribution system in the Village of Coldwater is nearing 100 years old.  Many of the distribution pipes are beyond life expectancy and undersized, and the network has shortcomings with respect to looping, valving, etc.  The Township of Severn retained CCTA to undertake design engineering and construction administration for a $4.5 million project to replace over 4,000 metres of existing watermain, with associated grading, drainage and roadway improvements.    The Township was successful in obtaining Building Canada funding for the project, and construction has now commenced and will continue until 2011.

Ontario Regulation 170/03 Drinking Water System Upgrades

CCTA is extensively familiar with the Safe Drinking Water Act, O.Reg. 170/03 and related regulations. CCTA completed water treatment system assessments, design, construction inspection and certification of compliance and Engineer's Reports for numerous drinking water systems serving municipal and private facilities in the Orillia, Collingwood, Blue Mountain, Muskoka and Haliburton areas, including children's campgrounds, resorts, mobile home parks, youth development and retirement facilities.

Water Treatment Plant Upgrades:  Village of Coldwater (Township of Severn)

Trichloroethylene (TCE) has historically been detected in the Coldwater municipal groundwater supply at low levels.  In 2004, The Township of Severn retained CCTA to conduct a TCE treatment feasibility study.  The study concluded that the implementation of carbon adsorption to remove TCE was the best solution. 

Water Treatment Plant Upgrades: Community of Caramat (Municipality of Greenstone)

Caramat, a northern community of less than 100 residents is located four hours north-east of Thunder Bay.  Drinking water is drawn from a small lake, which presents complex  water quality issues such as very high colour, organics, and turbidity.  The existing water treatment system could not effectively treat this complex raw water, and when chlorinated, resulted in Trihalomethanes forming at unacceptably high concentrations.  This resulted in long-standing drinking water advisories issued by the local Health Unit, and the requirement to supply the residents of Caramat with bottled water. One of the primary design objectives was to have a fully automated, low maintenance facility. A pilot study completed in 2004 resulted in the selection of the MS Filter Inc. slow sand filtration system complete with ozone pre-treatment.  This system operates by gravity and comprises three filtration steps: roughing filter, slow sand filter, and granular activated carbon filter. The slow sand filter comprises a biological filter medium (schmutzdecke). The pre-ozonation oxidizes the organics in the raw water, improving filtration efficiency. The water treatment plant includes the latest SCADA control and communication equipment to minimize operator time on site.  It was officially opened in December 2007.

Water Storage and Pumping: Town of Collingwood

Following a successful Schedule B Class EA study, CCTA completed the design and construction administration of Collingwood’s Pressure Zone 2 water reservoir and booster pumping station.  The facility, which draws from the Collingwood to Alliston water transmission main, will supply potable water to the residential and industrial developments in the southern and western areas of the municipality.  The project, completed in 2008, consisted of a 2,500 cu m grade-level reinforced concrete reservoir attached to a booster pumping station equipped with vertical turbine pumps in cans. The facility, with a Phase 1 capacity of 172 L/s, is designed to be expanded to 368 L/s, and to supply the future Zone 3 Pressure Zone.

Taylor Road  Depressed Sewer Schedule B Class Environmental Assessment - District Municipality of Muskoka

CCTA completed a Schedule B Class EA planning process to study the alternatives for replacing the sanitary sewer crossing of the Muskoka River - North Branch in the Town of Bracebridge.  The existing sanitary sewer was over 50 years old and too small to service the east side of Bracebridge.  Following a review and assessment of available alternatives CCTA recommended construction of a triple depressed sanitary sewer crossing of the River.  Conventional boring beneath the River was not possible due to poor soils, debris from historical logging operations and irregular bedrock.  The three pipes are laid on the bottom of the River, covered in a heavy stone armour to protect them from ice floes and floating trees and docks which travel down River during the spring freshet.  The project was completed in 2009 at a cost of $1.1 million.
