Merrilands Domain) on a total of 17 individual site surveys, and detaching or detached mats
accumulating on the river’s edge triggered the ‘Alert’ level at the same four sites on a total of
15 surveys. Levels of cyanobacteria were lower than in the previous four seasons; the
improvement was probably caused by above-average rainfall causing a large number of

The Climate Change Projections for New Zealand report analyses expected changes in New
Zealand’s climate such as temperature, rainfall and other climate variables, out to 2120, and
draws heavily on climate model simulations from the Intergovernmental Panel on Climate

caused difficulties at various sites in the past as localised rainfall may impact on
bacteriological quality on isolated occasions]. Where necessary, a 2 metre sampling
pole was used for bacteriological sample collection immediately beneath the water
surface and at a minimum of calf depth at the sites. Thirteen samples were collected
from each site during the season.
Samples were analysed for enterococci, E. coli and faecal coliform bacteria, turbidity

The Waitara scheme is now very resilient. But there remains a small risk that damage could
occur during a very large flood, which might compromise the level of protection afforded to
the township. We keep a careful eye on the scheme’s performance during very heavy rainfall
and occupants can expect a timely warning if we do see greater risks emerging.
However, the risk factor today is extremely low compared with other risks to property, such
as damage from high winds.

infiltration expenditure during the 2021-2022 monitoring year consisted of:
• $3,325 spent on pipeline renewals
• $891 spent on CCTV.
The expenditure for pipeline renewals was entirely on project management, investigation and design. No
construction occurred.
A wastewater network modelling project is underway which uses rainfall and flow data to create a calibrated
digital model of the entire Inglewood wastewater network. The calibrated model will be used to assess
network performance
How do I identify Critical Source Areas?
Look for areas where water accumulates during rainfall events and which also
connect to water bodies. These are Critical Source Areas. These areas can be
on steep or shallow slopes. If you are unsure, talk to your council or farm
advisor. See the next page for some examples of Critical Source Areas.
Am I allowed to graze stock in Critical Source Areas?
From 1 May to 30 September, stock cannot be grazed in Critical Source Areas
