OUR PROJECTS

MIDHURST WATER TREATMENT PLANT TOWNSHIP OF SPRINGWATER, ONT.

Geranium Corporation retained TMIG in association with DLW Engineering Services Limited to design and administer the construction contract of the Midhurst Carson Road Water Treatment Plant. The water treatment plant was designed to service an ultimate equivalent population of 8,727 persons and sized for an ultimate maximum day capacity of 6.6 ML/d. The project includes the predesign of the ultimate water treatment plant with ion exchange for nitrate reduction and greensand filtration for iron and manganese removal. The project also included the detailed design of an Interim WTP for the initial phases of development which included a 2 ML/d ion exchange water treatment plant which includes new wells, cartridge filtration for iron and particulate removal, ion exchange reactors for nitrate removal, ultraviolet disinfection, chlorination, and a 2 ML inground reservoir.

The interim water system includes a well-based water supply system complete with two (2) non-GUDI wells, and individual well houses. The distribuion system was modelled hydraulically to ensure that the system had adequate pressures and flows at all nodes in the distribution network while ensuring adequate disinfection and water age under all operating conditions.

SHERWOOD FOREST BOOSTER PUMPING STATION UPGRADES,

EAST GWILLIMBURY, ONT.

The Region of York retained TMIG in association with DLW Engineering Services Limited to complete the condition assessment, preliminary and detailed design, contract administration, start-up and commissioning of the Sherwood Forest Booster Pumping Station Upgrades. The work involved process, mechanical, structural, architectural and instrumentation and control upgrades to a 4.4 L/s potable water pumping station. The work included converting the station from single phase power to 3-phase power, and replacement of its outdated MCC, duty and fire pumps, pressure tanks with all associated piping and valves. The work also included process mechanical upgrades and installation of a new flow meter in an existing Davis Drive Metering Chamber

PINE VALLEY SEWAGE PUMPING STATION AND PEDESTRIAN BRIDGES VAUGHAN, ON

The Block 40/47 Landowners Group retained TMIG in association with DLW engineering Services Limited to design of a new sewage pumping station with an initial peak flow rate of approximately 128 L/s and an ultimate peak flow rate of 274 L/s. The station was designed as a wet well/dry well sewage pumping station. The work included the design of two trenchless crossings of a creek, a new 2 hour peak emergency storage tank, and odour control facilities. The project included the Value Engineering of the completed design in an attempt to reduce the project costs. Accordingly, the pumping station was redesigned with a much shallower wet well and with two pedestrian bridges spanning Purpleville Creek to carry the influent sewers and watermains to replace the two trenchless crossings. The resultant changes effectively reduced project costs by approximately $10M. The work included design, administration of the multiple construction contracts and start-up and commissioning of the works.

FRIDAY HARBOUR RESORT WATER AND WASTEWATER SERVICING,

INNISFIL, ONT.

Geranium Corporation retained TMIG in association with DLW Engineering Services Limited to design two sewage pumping stations, two stormwater pumping stations and a 3.7 ML potable water standpipe. The two new wet well/dry well sewage pumping stations (with capacities of 109 L/s and 119 L/s) with one having a 300mm diameter by 2.6 km long forcemain and the other with dual 250mm diameter by 1.3 km long forcemains. The work included the predesign, detailed design administration of the multiple construction contracts and start-up and commissioning of the works.

AURORA SEWAGE PUMPING STATION HAULED WASTEWATER TREATMENT SYSTEM

AURORA, ONT.

York Region retained TMIG in association with DLW Engineering Services Limited to design and administer the construction of a new hauled wastewater treatment facility at the existing Aurora SPS. The work included the completion of the preliminary and detailed design, and pre-purchase, tender assistance, and administration of construction for the pre-treatment equipment for the Aurora SPS hauled wastewater treatment facility. The work includes the installation of a pre-treatment unit in a pre-fabricated building to remove screenings and grit from the hauled wastewater discharged to the station. The pre-treatment unit is designed as a pre-fabricated, pre-engineered unit.

The design enabled the facility to allow for three hauler trucks to discharge hauled wastewater simultaneously. The unloading area was equipped with a card access system, and three pipe lines with quick connects. All three lines discharge to a holding / equalization tank where two submersible pumps transfer the waste to a pre-treatment system prior to discharging to the sewage pumping station wet well.

FLATO/OXNARD SOUTHWEST BEETON SEWAGE PUMPING STATION,

BEETON, ONT.

Flato Developments Inc. retained C.F. Crozier & Associates Consulting Engineers in association with DLW Engineering Services Limited to design and construct a new wet well/dry well sewage pumping station to service a new development in southwest Beeton. DLW is providing hydraulic and facility design expertise for a new sewage pumping stations (22 L/s), to service a proposed development in the Township of Southgate. The facility is equipped with submersible pumps and with a control building to house controls, standby generator and odour control facilities. DLW is subconsultant to Crozier on this assignment and is providing project management assistance as well as lead hydraulic and facility design services

FLATO DUNDALK MEADOWS WASTEWATER PUMPING STATION,

DUNDALK, ONT.

Flato Developments Inc. retained C.F. Crozier & Associates Consulting Engineers to design and administer the construction of a new sewage pumping station to service a new development in Dundalk. DLW is providing hydraulic and facility design expertise for a new sewage pumping stations (36.9 L/s), to service a proposed development in the Township of Southgate. The facility has a wet well with submersible pumps and with a control building to house controls and odour control facility with a pad mounted outdoor standby generator set. The station has been designed for multiphase design approach that allows the station to be initially designed for 12.5 L/s and expandable for the ultimate capacity of 36.9 L/s. DLW is subconsultant to Crozier on this assignment and is providing project management assistance as well as lead hydraulic and facility design services.
