Managing wet weather sewage spills in a challenging environment
19/10/2011
Sewage spills into the Whangarei harbour during wet weather cause a public health risk to those using the harbour for contact recreation and shellfish collection. Solving the cause of the spills, inflow and infiltration of stormwater into the sewer network, is made difficult for a number of reasons including: the inability of the community to fund large capital projects, Whangarei’s high rainfall rate, the private and public sewer network is aging, and the soil type exacerbates inflow and infiltration.
