Selwyn District Council have reported that Christchurch City Council are now able to start taking and treating sewage from Lincoln, Springston, Prebbleton and Tai Tapu once again. This means that discharge of raw sewage to the Halswell and LII rivers from these settlements has stopped, which is great news for the rivers and the Lake.

Preliminary results of testing for E. coli carried out at number of locations in the Lake have shown that levels are very low and well within the normal range. Levels in the lower reaches of the Halswell (tested before the discharge stopped) were around twice the acceptable level for contact recreation, but that should improve now.
