Operation and maintenance costs of drinking water plants — Treating primarily surface water, by production volume
Table summary
This table displays the total and unit operation and maintenance costs of drinking water plants treating primarily surface water, broken down by production volume category for 2011. The row headers are comprised of the all production volume categories total and seven production volume categories, with units of thousands of cubic metres per day. The column headers are comprised of Total costs and Unit costs, and they both have the following subheaders: Materials, Labour, Energy, Other and Total. The unit of measure for the Total costs is millions of dollars, and that for the Unit costs is dollars per thousand cubic metres. The Materials subheaders have a note which reads "Includes chemicals and replacement parts." The Labour subheaders have a note which reads "Includes internal and external staff including laboratory personnel." The Other subheaders have a note which reads "Includes costs such as waste disposal and residuals handling, analytical/sampling costs, any associated administration and service costs directly related to operation and maintenance (consultants and contractors) and costs related to waste treatment processes (that is, backwash processing and residuals disposal)." The units for the production volume categories (thousands of cubic metres per day) have a note which reads "One thousand cubic metres is equal to one mega litre." The table has a note which reads "Cost per unit volume will vary within each category due to various sizes and configurations of plants. Includes plants treating 90% or more surface water and costs related to the acquisition and treatment, but not the distribution, of water. Figures may not add up to totals due to rounding."
