stormwater infiltration. Figure 3 shows ammoniacal nitrogen results since 2005. Some of the higher results
(e.g. 2015), can be attributed to heavy rainfall preceding sampling.

Stormwater from the production station is collected and discharged at three separate points. The water level
in the firewater pond in the north western corner of the site is maintained by an abstraction from the
Ngaere Stream. Overflow due to rainfall entering this pond is discharged to land and to the Ngaere Stream
to the north of the pond. Stormwater from the process areas is directed to a
located upstream of the discharge (WGG000500 and WGG000510), one site at the discharge
location (IND00400) and two sites located downstream (WGG000540 and WGG000620) of the discharge.
Black disc measurements were also taken upstream and downstream of the discharge in compliance with
the requirements of consent 2039-4.1.
Stormwater sampling was undertaken by the Council, during the two sampling rounds. Sampling was not
undertaken during or immediately following any heavy rainfall periods when …
of a good standard. Monitoring of the microfloral component of the tertiary cell of the
secondary pond (using chlorophyll-a measurements) indicated that the system had a low algal content,
particularly following heavy rainfall events. Microfloral populations have not indicated poor performance of
the treatment system to date and generally indicate an improvement in conditions in the tertiary cell since
the last WWTP upgrade.

chamber was emptied. The screens were being cleaned frequently and this was due to increase further with
an anticipated increase in rainfall over winter and spring. A significant amount of work has been proposed
to upgrade the water pipe that carries water from the river to the plant. This work is in the planning process
and will include a more accurate flow meter at the river. …
