Reference product: tap water [kg]
Location: CA-QC - Canada, Québec
This dataset represents production of 1 kg of tap water under pressure at facility gate, ready for distribution in network. It represents average operation of tap water using artificial recharged wells technology. Water intake is a mix of groundwater and surface water (60:40). Surface water recharge hole where it settles and is then filtered through natural soil. Water is pumped from aquifer, disinfected and pressurized for distribution. Inventory was constructed from reported chemicals, energy inputs and wastes from a single plant located in Québec covering nearly 100% of total production of tap water from this technology.
[This dataset has been generated using the system model "Allocation, cut-off by classification". A system model describes how activity datasets are linked to form product systems. The allocation cut-off system model subdivides multi-product activities by allocation, based on a physical properties, economic, mass or other properties. By-products of waste treatment processes are cut-off, as are all by-products classified as recyclable. Markets in this model include all activities in proportion to their current production volume.
Version 3 of the ecoinvent database offers three system models to choose from. For more information, please visit: https://www.ecoinvent.org/database/system-models-in-ecoinvent-3/system-…)]
