Ofqual (UK NZQA equivalent) released the details behind the algorithm in a 319-page technical report at the same time as releasing the results - check out this accessible explainer from Jeni Tennison.
(The situation arising after final exams had to be cancelled due to the Covid-19 pandemic.) Got it.On Monday the UK government was forced to U-turn from letting an algorithm decide A-level results (equivalent of NCEA level 3 in AoNZ) in place of teacher predictions. Use less water so we don’t run out, but use more water so that it costs less, so that the City makes more money to make sure that they can replace the extra water you used because it was cheaper to use more water than when you were using less water. Should the amount of water we are selling significantly increase this will be factored into the tariffs, but given the uncertain impact of climate change it may not be wise to actively encourage such an approach at this stage. It is important that the City cover its costs to ensure that the maintenance and augmentation programmes can be carried out. Currently, the City is selling approximately 30% less water than before the drought, but is facing additional costs that come with increasing our resilience. Regarding tariffs: as previously stated, a reduction in tariffs will be dependent on an increase in consumption.
Mayoral Committee Member for Water and Waste, Alderman Xanthea Limberg says: This probably did have some effect, but now that the dams are nearly full for the first time in 6 years, isn’t it time to reduce those tariffs? The problem is that the City is selling much less water than it used to, while the efforts aimed at avoiding Day Zero two years ago were costly, and the plans to safeguard the city’s supply in a uncertain future doesn’t come for free.Īlso, reduce the price of water and it stands to reason that consumption will go up again, which won’t help anyone, but might make up the shortfall in revenue. One of the City’s methods of reducing water usage was to increase tariffs.
We’re using just over 630 million litres per day, as opposed to the almost 1 billion litres per day prior to the nastiness of the drought in 2016-2018. So yes, a few things like borehole augmentation, clearing of inflows and a reduction in alien vegetation around the dams will have helped, but it’s the fact that Capetonians are now using only just over half as much water each day as they used to which is making the biggest difference. Thankfully, not like 2011 (that’s the low line), but also definitely not like 2001 (that’s the very, very high line) either. That’s the 8 months of 2020 so far in orange. In fact, this winter has been decidedly average. … a far cry from the panic of literally running out of water not so very long ago, this has not been down to this being a particularly wet winter. Even though our dams are at a very healthy 95.6% of capacity…
