Changes to the Water Services Act 2021 have meant that when you supply more than one household by the same water source, you are classified as a drinking water supplier and therefore responsible for ensuring the provision of safe drinking water. 

We help our clients to assess irrigation system performance. This includes independent checks during system commissioning, resource consent condition compliance, and farm environmental plan requirements. In some cases, assessments reveal underperformance, often linked to system modifications such as irrigator upgrades.

The Waimea Plains situated in the Tasman District are a valuable source of groundwater. The hydrogeology of the plains consists of three key aquifers separated by aquitards. Aqualinc was engaged by Tasman District Council to develop an integrated surface water-groundwater flow model of the system and evaluate various water management strategies.

Following the 2010-2011 Christchurch earthquake sequence, a network of piezometers was installed by the Earthquake Commission across Christchurch to monitor shallow groundwater levels. This is referred to as the Automated Piezometer Programme (APP) network.

Aqualinc has worked with Tasman District Council (TDC) over many years to develop and refine an integrated surface water-groundwater model of the Motueka-Riuwaka groundwater system and have applied this model to evaluate various water management strategies.

Aqualinc delivered a comprehensive update to the National Irrigated Land Spatial Dataset (originally created by Aqualinc in 2017), providing critical information for effective water resource management and environmental reporting in New Zealand.

As part of the review of the National Environmental Standard for Sources of Human Drinking Water, the Ministry for the Environment commissioned a report on the potential impacts of national implementation of drinking water source protection zones.
