Pollution Events Dashboard

RiverCare Group Te Wai o Pareira has been monitoring the awa since 2018. One of the major current sources of pollution are wastewater overflows from the sewage system.  Watercare have automated sensors installed on 8 of the 12 points where overflows can occur.  These sensors give notifications of when an overflow starts and ends.  Here is a list of the waste-water overflow events that we have been advised of since July 5 2022.  Overflows mostly happened when the system's flow capacity is exceeded during heavy rainfall events. The data shown below covers the overflows we are aware of.  Also included below are the Enterococci test results at various sites on the awa.
