collection and retention systems; stormwater sampling and inspections
of the discharge point and receiving waters in the Herekawe Stream. Scheduled inspections were carried out

6 July 2023
First inspection for 2023/24. On site 14:00 to 14:50 representatives from Dow, Tonkin & Taylor and SGS.

There are certain operational requirements also set by consents, which require flushing flows of 400L/s to be
released down the residual flow reach once the Tariki weir has not naturally overtopped for 30 days. There
