water treatment emissions

[baywet]

Hi Team, I'm writing to follow up on #404 . Now I understand the team is busy with other priorities to build a dedicated UI if we add another model. In the PR discussion it was indicated to add it as a purchase instead, and I'd like to get guidance/understand what's already there so I don't send another PR which ends up being closed. We have multiple entries in the purchase model:

• WATER SUPPLY AND MISCELLANEOUS SERVICES RELATING TO THE DWELLING -> this one takes a price to work. Which does not work for places where water is not billed based on a metered consumption like here in Quebec. (square footage based tax instead from the town)
• Water (bottled) and the other one right below -> this seems to include the emissions of sourcing, (bottling), and transporting the water, but not treat it. Plus it's measured in glasses. Not very practical for your shower related emissions...

So my questions are:

• should we reuse/adapt any existing water entry? or add a "water treatment" entry?
• if we're adding an entry, I'd like it to be in m3, which is practical for housing consumption, not priced base, would this be ok?
• if we're adding an entry, under which category should this be added?

Thanks for the help!

Hi @baywet, Thank you very much for pushing forward on this. I don't know if you're aware that we're sunsetting the North app (see https://www.tmrow.com/blog/sunsetting-north/). This repository is now geared towards the Bloom (bloomclimate.com) product geared towards SMEs.

This doesn't mean the water model will not be used, but it means that it will be of lower priority for us in terms of UI.

As guidance, I suggest adding a water purchase in m3. It doesn't need to be price based. The ambition with footprint.yml is to be a tree based on coicop categories, see https://unstats.un.org/unsd/classifications/unsdclassifications/COICOP_2018_-_pre-edited_white_cover_version_-_2018-12-26.pdf

I suggest introduce a new category corresponding to water? Maybe this one?

thanks for sharing. Closing as I won't invest time in an app being sunset. Too bad it was a good app. Good luck for the next steps!
