hydrogeologic conditions (Taylor and Evans, 1999). These result in a complex
system of unconfined, perched and semi confined aquifers within the volcanic deposits. The water table in
the ring plain area is typically encountered between 1 to 10 m below ground level. Seasonal variations in
water table depth of up to 5 m are common. Groundwater flow generally reflects surface topography and
flows radially from Mount Taranaki. Recharge to the Taranaki volcanic aquifers is mainly by rainfall

three day period
following significant river/stream fresh conditions. [NB: regional differences in
rainfall patterns have 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 all but one site (12 samples)

Special condition 9 of 1134-3.2 requires CCCWSL to introduce conservation measures when the flow in the
Cold Stream immediately downstream of the intake point is less than 209L/s. This requires that the taking of
water be restricted to the minimum amount necessary to maintain the health and welfare of people and
animals (i.e. garden watering and other non-essential uses are prohibited). The 2023/24 season experienced

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 under different storm events of varying duration and return interval, along with
projected
