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. 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.
Wastewater Overflows data
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 happen when the system's flow capacity is exceeded during heavy rainfall events or when there is a blockage in a pipe.

Enterococci Levels
Recreational activities like swimming, sailing, rowing, water skiing and kayaking are popular along our river, bringing people in close contact with the water. Testing for Enterococci helps us determine whether the water is safe for these activities. Enterococci are bacteria commonly found in the intestines of humans and animals. While they might seem insignificant, their presence in river water serves as a critical indicator of fecal contamination
High Enterococci levels can indicate a heightened risk of waterborne illnesses. Rivercare Group is unaware of any regualr testing programme being undertaken on the awa, but our testing in 2020 assisted Auckland Council to establish the two Safeswim sites on Te Atatu Peninsula at Taipari Strand and Chapman Strand. We also proactively test at other locations and alert Auckland Council of results/
