Waikato Regional Council - Water Quality Monitoring

 

Requirements:

NZDF is required to collect streamflow data for the life of the consent and thoughout the year, at their secondary drinking water take.

 

Solution:

Hydro Logic NZ Ltd has successfully installed a ‘telemetered’ water level station which allows us to monitor the water level remotely via the internet. We then develop a ‘rating curve’ which is simply a stream height vs stream flow relationship. This can then be applied to the stream height at any time to provide a streamflow to the regulatory authority to satisfy the consent requirement.

 

We utilized an electronic INW pressure sensor in the stream to measure the water level , and an Outpost datalogger/modem setup to store and send the data via the Vodafone network.

 

The plant operator can access the data via a secure log-on to effectively manage their irrigation consent and ensure that they do not exceed any consent conditions.

 

The data is hosted by Watercheck in Christchurch who are a specialist data provider linked to Water Supply Products. See data example below.
