Reg. 170/03 Section 11 Reporting Description of the Holland Landing Drinking Water System About Holland Landing Holland Landing is a village in the Town of East Gwillimbury, located in the northern part of York Region. It sits roughly between Yonge St, Highway 11, Mount Albert Road and Queensville Sideroad. York Region manages the water supply of two wells, two elevated storage tanks and one booster pumping station. Lake Ontario water is also supplied from the south by the York Drinking Water System (York DWS). The Town of East Gwillimbury maintains and distributes the water to consumers from the Regional supply. The Holland Landing Drinking Water Sub-System is part of an interconnecting system between Aurora, Holland Landing, Queensville, Newmarket and the larger York DWS. Connection to the York DWS reduces demand on the aquifers and provides a secure secondary source of drinking water. Raw Water Source Description Ground water taking is regulated by a Permit to Take Water issued by the Ministry of the Environment and Climate Change. The City of Toronto and Peel Region have permits for taking Lake Ontario water. Supply agreements govern the purchase of water from the City of Toronto and Peel Region. Two wells extract groundwater from a deep aquifer. Iron, manganese and hardness levels are naturally elevated, which is common in deep aquifers across York Region. Staff use raw water test results to monitor the health of the aquifer and determine the best water treatment. Water Treatment and Supply Disinfection is maintained with chlorine gas and ammonia (chloramine). Sodium silicate is added to manage iron and manganese in the distribution system. The storage facilities hold water for peak demand use, and maintain pressure in the system. The booster pumping station also maintains pressure. In addition to routine water testing and facility inspections by Operators, online analyzers continuously monitor the treatment and delivery processes. These analyzers trigger alarms and automatically shut down and lockout pumps to notify Operators when immediate attention is needed on site.
