O&M cost models developed for selected systemsДЇor conventional plants treating surface water, ordinary least squares Vary with annual production volumes for unfiltered systems treating groundwater. Survey data were used to develop a model to explain how O&M costs In the treatment of groundwater, the analysis in this article focuses on unfiltered 21 Because these systems were among the dominant ones These are referred to as unfiltered systems treating Supplies (232В Mm 3) was produced by systems that applied disinfectionДЄs well as other processes. 19 Table 2 shows that inВ 2007,ДЄbout one third (34%) of the total volume of water treated from groundwater Treatment approaches therefore differДЇrom those applied to surface water supplies. With respect to groundwater supplies, in most cases the ground can protect How O&M costs vary with annual production volumes for conventional treatment Survey data were used to develop a model explaining In the treatment of surface water, the analysis in this article focuses onД¬onventional treatment plants. Water plants (2,640В Mm 3) was treated by conventional systems. Over half (53.5%) of the total volume of surface water treated at drinking Is referred to as 'conventional' treatment. Granular media filtration and disinfection. Surface waters such as lakes, rivers and streams are susceptible to pollutionДЄnd almost always require treatment by coagulation, flocculation, sedimentation, To: Survey of Drinking Water Plants (survey no. The treatment plantsД¬overed by the survey provided water for aboutВ 85% of the Canadian population.ДЇor further information on data quality, concepts and methodology please refer Type, capital and operating costs and water quality. It collects data on the volumes of water withdrawn and treated, treatment With a target population of allДrinking water plants serving communities ofВ 300В or more people, Related to the production of drinking water. The survey provides national and regional information TheВ 2007В Survey of Drinking Water Plants, a new survey conductedД«y Statistics Canada. The primary data source for this article was Systems, which treated the most groundwater. Systems: conventional systems, which treated the most surface water and unfiltered This study analyzes the data collected by the survey to illustrate Vary by treatment technology, annual production volumes and the type of source O&M costs associated with the acquisition and treatment of water will Other costs accounted for the remainingВ $108В million. ($302В million), while material and energy costs representedВ $198В millionДЄndВ $199В million respectively.

The largest component of these expenses was labour costs Water, but exclude water distribution costs. Replacement parts), labour and energy for the acquisition and treatment of Of Drinking Water Plants include expenditures on materials (chemicals and Operation and maintenance (O&M) costs data collected by theВ 2007В Survey Surface water (GUDI sources) which servedВ 460,000В people inВ 2007. The remainingВ 2% came from groundwater under the direct influence of ProvidedВ 10% of the water and servedВ 3.5В million Canadians.
