Making the Wastewater Treatment Plant less stinky
Can you smell the wastewater treatment plant on Kioreroa Road? 🐷
We've got a plan to make it less smelly: covers and odour treatment systems (bio filters) will be installed around the four stinkiest parts of the plant between now and September 2025. What are those 4 parts? Buckle up.
💩 1: the inlet works (where the untreated sewage comes in for treating), screenings bin (where the lumps go, including old barbie dolls and false teeth)
😷 2: the sludge thickener tanks (that reduce the water in the sludge prior to disposal)
🟫 3: the sludge holding tanks (exactly what they sound like)
🐌🐌 4. the snail bin. The water treatment plant has four large trickling filters - large round bins filled with granite rock. The wastewater trickles over the rocks and the algae growing on them. The algae take massive amounts of nutrients out of the wastewater and clean it up. It’s a very robust and natural process, accelerated by engineering and technology.
The algae attract small snails (3mm), which just love the environment in the trickling filter – it is wet and full of food. The snails grow there by the billions. Every now and then, a few snails are swept out with the wastewater and are filtered out before the water goes to further cleaning.
Those “few snails” however, add up to 2-3 cubic metres per week. We put them in our snail bin and empty it weekly. However, this is long enough for it to over-power all the other smells in the wastewater treatment plant.
Poll: Should we ditch daylight saving? 🕰️
First introduced in New Zealand in 1927 with the passing of the Summer Time Act, it's what we know as 'Daylight Saving' and this year it ends on the first Sunday in April.
While we do get to sleep in this time around, some people would like to scrap the clock tinkering for good.
And why? Some evidence suggests the time changes are bad for our health as they mess with sleep patterns leading to short-term fatigue and affecting mood. Meanwhile the hour change is frustrating for farmers and a nightmare for getting the littlies to sleep. But what's your take?
-
39.7% Yes - get rid of the clock changes
-
58.5% No, I enjoy it
-
1.8% Other - I'll share below

Be careful out there...
If you can, stay home today, and if you are travelling, please drive to the conditions. While we've had consistent rainfall overnight, the forecast is still likely to bring: dangerous river conditions, flooding, slips and landslides, hazardous driving conditions, and road closures in some areas. Northland Regional Council have shared some important updates this morning.
🚩 The Red and Orange Heavy Rain Warnings, as well as the Strong Wind Warning issued by MetService New Zealand, remain in place until the early hours of tomorrow morning. The key period of concern is still today through to Friday morning.
🚩 Many rivers in the Far North are running at high levels, with some still rising. (High tide on the east coast is early this afternoon.) The Kaeo River has reached a level where flooding on SH10 is possible. So if you’re travelling through Kaeo or Waimate North this morning, please take extra care.
🚩 There are already a number of State Highway closures and there are likely to be more, as well as local road closures. Crews will work to clear these as quickly as possible, but there may be delays. If you come across any local roading issues or storm related damage on public property, please report it through to your local council:
Whangarei District Council: www.wdc.govt.nz...
Kaipara District Council www.kaipara.govt.nz...
Kaipara District Council www.fndc.govt.nz...
🚩 There are a number of isolated power outages around the region. Northpower and Top Energy NZ crews will be out today working to resolve these issues as soon as they can, but this may take some time.

Finally, some key reminders for today:
- Do not enter floodwaters: it only takes a small amount of moving water to knock you off your feet or sweep a vehicle away.
- Avoid unnecessary travel over this period. Conditions may deteriorate quickly, and roads may close with little warning.
- Be prepared to self evacuate if you see rising water, feel unsafe, or notice conditions worsening.
- Be aware of landslide risks, and keep well away from areas that have recently been affected by slips or landslides. If you notice cracks in the ground, tilting trees or power poles, unusual noises, or rapid changes in stream levels, leave immediately.
If at any time you feel you, your whānau, or your property are at immediate risk, please call emergency services on 111
Civil Defence will continue to monitor the situation closely and provide updates here as more information becomes available.
This remains an evolving situation, so please continue to keep up to date with the latest information from MetService, NZTA and your local and regional councils.
