This dataset represents the construction of a medium size (class 3) wastewaster facultative aereted lagoons treatment facility. Average flow rate for this class is 13689 m3/d (5.0E9 l/yr) with a lifetime of 40 years. Lagoon treatment includes influent pumping station, ponds and UV disinfection. Dataset is extrapolated from a one lagoon facility in Quebec (CA): average flow of 8050 m3/d. Inventory is extrapolated to a small size plant based on cost curve.

Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.
