Matamata: Your water is safe to drink!
Your water comes from here:
- Tills Road – surface water source
Amount of water average of 4,700m3 per day or up to 4.7million litres.
Population: 6, 943 (as at 2015)
Number of samples taken: 573 compliance related samples for bacterial compliance – no E.coli detected in the samples.
Tills Road:
What we achieved:
- Part 4 of the DWSNZ (Treatment plant)
- Part 4 of the DWSNZ (Distribution zone)
- Part 7 of the DWSNZ (Cyanotoxin compliance)
- Part 8 of the DWSNZ (Chemical compliance)
|
What we didn't achieve:
- Part 5 of the DWSNZ (protozoa compliance, process only)
|
Why we didn't achieve it:
- The water coming through from the filters exceeded 2 NTU (the unit used to measure the clarity of the water) for 3 minutes on six different occasions.
- The UV strength being below the required level a number of times in four months.
- The boil water notice issued in October 2018 – due to us not being able to demonstrate that the treatment of the water was compliant. (This was only due to missing data from online instruments not reporting back to our IT systems).
|
How we're addressing it:
- Upgrading our communication network between the online instruments at the treatment plant and our IT systems to ensure that data does not go missing.
- District wide we have invested over $2M to upgrade treatment plant instruments and processes.
- Full alarm review has taken place improving the timeframe between when non-compliances are about to occur and when the alarms are sent to our water treatment technicians (creating faster response times).

Tawari Street:
What we achieved:
- Part 4 of the DWSNZ (Treatment plant)
- Part 4 of the DWSNZ (Distribution zone)
- Part 8 of the DWSNZ (Chemical compliance)
- Part 9 of the DWSNZ (Radiological compliance)
|
What we didn't achieve:
- Part 5 of the DWSNZ (Protozoa compliance, process only)
|
Why we didn't achieve it:
- No protozoa treatment process in place.
|
How we're addressing it:
- A new UV unit was installed in September 2019 for Protozoa treatment
- District wide we have invested over $2million to upgrade treatment plant instruments and processes

Burwood Road:
Matamata South – ground water source
What we achieved:
- Part 4 of the DWSNZ (Distribution zone)
- Part 8 of the DWSNZ (Chemical compliance)
- Part 9 of the DWSNZ (Radiological compliance)
|
What we didn't achieve:
- Part 4 of the DWSNZ (Treatment plant)
- Part 5 of the DWSNZ (Protozoa compliance, process only)
|
Why we didn't achieve it:
- Secure bore status was removed for this bore at the end of June 2018. The number of samples taken during July – August 2018 did not increase to reflect this status change (from secure status to non-secure status).
- No protozoa treatment process in place.
|
How we're addressing it:
- At the end of August 2018 the sampling schedule for Burwood Road was increased to reflect the non-secure status. Amount of samples for the remainder of the compliance year was correct).
- UV unit installed in September 2019 for protozoa treatment.
- District wide we have invested over $2M to date, to upgrade treatment plant instruments and processes
