Well, it turns out 2021 was a [record breaker!](https://www.stuff.co.nz/national/weather-news/127476295/wellington-weather-in-2021-a-recordbreaking-year-of-heavy-rainfall-aboveaverage-temperatures)
2022, not wanting to be outdone, then went on to be a [record breaker.](https://www.stuff.co.nz/national/weather-news/129992070/wellingtons-winter-wettest-on-record-new-figures-show)
But you're thinking to yourself, come on 2 years in a row doesn't make a pattern. So [here's 2023.](https://niwa.co.nz/news/2023-so-far-nzs-record-breaking-weather)
According to a report from NIWA called [Climate change projections for west of Wellington’s Tararua and Remutaka Ranges,](https://www.gw.govt.nz/document/20064/climate-change-projections-for-west-of-wellingtons-tararua-and-remutaka-ranges/) this is only going to increase over the next 40 years.
Edit: it turns out 2023 wasn't a recordbreaker for Wellington. I should have thoroughly read through everything before posting the links.
High rainfall? How is rainfall in the stormwater system getting into the sewerage system?
Christchurch fixed this in 1990s with house to house inspections and compliance orders (same for industrial sites).
Inflow & infiltration. Inflow from illegal stormwater connections to wastewater, washbays with no roofs to stop the rain etc. Infiltration from groundwater getting into cracked wastewater pipes, made worse during rain when the water soaks into the ground.
Still an issue for christchurch.
I recently swam at Shelly Bay (18th April). Is there known sewerage run off there at times? The first time I went the visibility wasn’t great and it had been raining in the lead up.
I believe the Porirua one was a false alarm.

Don't panic. We have a plan... Ops, election over, plan binned...
Same is being done in the UK

“sigh”
What is the fine for these illegal discharges? Similar to fines that Farmers and factories receive?
Even if there was - who pays it? The rate payers!
Lol
