GEL has provided project management, detailed design, contract administration, inspection, and warranty administration on a new subdivision located within Alliston in the Town of New Tecumseth, Ontario. The subdivision will include 1,450 single family homes and 420 townhome units, designated commercial space in excess of 5.0 ha, a school block with a Catholic School opened in Fall of 2022, two park blocks with basketball courts, beach volleyball nets, a splash pad and jungle gym, an off-leash dog park and a 1km trail system. There are three stormwater management facilities, two sewage pumping stations, one water booster station, and one water reservoir. The total proposed subdivision covers approximately 150ha of land.

The Development’s internal waste water collection and distribution system was constructed as per the respective Township Engineering Standards and Ministry of Environment (MOE) design guidelines. The projected daily average and peak sewage flows from the subject property are calculated using the referenced criteria and the proposed full build-out of the subdivision. The Development is divided into two large sanitary catchment areas, one to the north and one to the south and includes the use of two pump stations, which ultimately pumps the entire development’s sanitary flows to the Town’s Regional Waste Water Treatment Plant (WWTP) which is located on the south side of the 14th Line approximately 2.1 kilometers west of the Treetops Development.

The Development’s northern sanitary flows drains to the Lorne Thomas Pump Station (PS2), located adjacent to the commercial block at the northwest corner of the development. PS2 will pump to the midway point of the Development where it will discharge into a gravity sewer and drain through the southern portion of the Development to the Cauthers Crescent Pump Station (PS1). PS1 has been designed and constructed to pump the entire Development’s sanitary flows to the Town’s Regional Waste Water Treatment Plant (WWTP) which is located on the south side of the 14th Line approximately 2.1 kilometers west of the Treetops Development.

The Development’s water distribution system features watermains ranging in size from 150mm dia. to 300mm dia., a water booster station (located externally), a water reservoir (located internally), multiple pressure reducing valve chambers located throughout the development to delineate and/or establish upper and lower pressure zones, and other necessary watermain appurtenances to optimize the system’s performance and meet required demands.
