For many years the Heathcote-Avon estuary was the dumping ground for Christchurch's sewage. Then, in 2010, the wastewater was diverted well out to sea, via a long pipe. David Schiel from the University of Canterbury and John Zeldis from NIWA were investigating the effects of this diversion on the health of estuary when the 2011 Christchurch earthquakes happened, re-engineering both the estuary and their experiments.
