of short duration.
Despite the operation of the aerators, dissolved oxygen levels in the primary pond
from time to time have fallen to levels lower than recommended for efficient pond
operation. A combination of high pond loadings, low dissolved oxygen levels, and
marked changes in weather conditions, contributed to a major deterioration in
primary pond performance (with

2.2. Results
2.2.1. Site inspections
13 October 2016
The site was inspected in fine weather with light easterly wind conditions.
The cap was well grassed with no ponding, cracking or exposed refuse noted. Heavy rain the previous day
had left the cap damp underfoot. It was observed that the remediated crack area was re-grassing well and
was nearly indistinguishable from the surrounding area. The batters
complaints were received by STDC and the Council concerning objectionable odours
emanating from the ponds system. These odours generally occurred at times of calm
weather (early morning and evening) and/or following aerator breakdown/
maintenance, and these incidents were usually of short duration.

rate from the pond to the Mangorei Stream will be highly variable as it is dependent on weather conditions.
The size of the pond will allow storage for a 10% annual exceedance event (AEP) event. The maximum
discharge rate from the pond during large rainfall events is 1,060 L/s as this is dictated by the size of the
