Abstract
Over the past 10-15 years WWTP control system performance has improved

significantly by increased usage of on-line WWTP data. It is now time to extend

the intensive use of on-line data to the sewer system, where on-line data can be

used within control of both sewer and WWTP. A generic methodology for

exploiting on-line sewer system data - as discussed in this paper - have revealed

that these data seem as useful for good control as on-line WWTP data. Also, the

integrated approach where sewer data are used for WWTP control and vice versa

has proven successful and valuable. The critical step in using on-line sewer

system data is to select sufficiently efficient methods... (More)

integrated approach where sewer data are used for WWTP control and vice versa

has proven successful and valuable. The critical step in using on-line sewer

system data is to select sufficiently efficient methods for data reduction and

information extraction. An approach to this is proposed, where on-line data are

evaluated to distinguish between the stable dry weather situations and clear rain

situations. This approach allows a fast identification of the catchment area and

rainflows, for example in pumping stations. The use of the developed methods

indicates that PST data provide more reliable information on the actual rain

distribution than rain gauges. (Less)
