I think that "CONSUMPTION usagewater" is meanning "PRODUCTION water"(cleanly water), then water imports to "STORAGE_IMPORT RESOURCE_TRANSPORT_SEWAGE".
So, displace "$TYPE_FACTORY" to "$TYPE_SEWAGE_TREATMENT",
add "$PRODUCTION water 0.25"
"$OUTWATER_MAX_QUALITY 0.9"
"$STORAGE_EXPORT RESOURCE_TRANSPORT_SEWAGE 20";
displace last two "$CONNECTION_SEWAGE_INPUT" to OUTPUT.

When the sewage input tank fills up the prodution drops to 0% does anyone know why?

Wanted to ask how to make a 100% usage of building. have max workers, sawage is filling but building is running only at 10% ussage max on any type of building. Any tip how to fix ?

i see pollution gets down to 0% on my full input, so that would be clean water? but it still has the sewage icon. would be nice to speed up loading the sewage or have it produce water maybe even with an out pipe.
but i guess pipe wont output the import storage...
great idea but unfortunatly does only work till its full :(

Have added oversized sewage import tank as suggested as a work around

Fixed potential crash

version 0.8.7.12
game crashes once the building is completed being built. Ive tried all 3 buildings with the same result.

Can you give more details on the crash? Also which game version are you using.

crashes game

New sewage Treatment version - https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=2824726106

Tried to change my config:

$STORAGE_EXPORT RESOURCE_TRANSPORT_SEWAGE 20

to

$STORAGE_EXPORT RESOURCE_TRANSPORT_WATER 20

without any other changes.

Result: it produces clean water from sewage :) can be transported via clean water tanks, clean water pipes etc.

I think it may be used for closed water loop, which was used for centuries :) ground => water well => usage => sewage is poured on plants => back to ground - can be cool for early starts (1900-1920)

@dbatyuk thanks I will take a look at that

It's dirty hack but worked for me:

$TYPE_SEWAGE_TREATMENT

$WORKERS_NEEDED 20
$CONSUMPTION chemicals 0.002
$PRODUCTION plants 0.15
$PRODUCTION water 0.5
$CONSUMPTION usagewater 0.5

$OUTWATER_MAX_QUALITY 0.99

$STORAGE_IMPORT_SPECIAL RESOURCE_TRANSPORT_COVERED 5 chemicals
$STORAGE_IMPORT RESOURCE_TRANSPORT_SEWAGE 20
$STORAGE_EXPORT_SPECIAL RESOURCE_TRANSPORT_COVERED 20 plants
$STORAGE_EXPORT RESOURCE_TRANSPORT_SEWAGE 20

Sewage is not working as I expected as a resource. I am looking into solution

I noticed a problem during operation, the warehouse of sewage reaches 0% quality and production is stopped.
Overall a nice idea for sewage consumption.

@vimes thanks. Yes there are dedicated sewage and water connections. Workers sewage is separate. I think makes it more realistic.

Too much production. 0.3...0.6 t/day is optimal, I think.

BTW Does it have a dedicated water and sewage connection(s) for the production and then need both drinking water and sewage collection...? Or does the sewage that it produces, from workers, contribute to the production needs of sewage, if that makes sense..?!

Most interesting, thanks for creating and sharing this.
I always thought that there could be a use for the sewage (fertiliser) combined with farms for an increase in crop yields. Adding a very small amount of chemicals to the mix is a good idea.
Well done.

Required water quality is 80%

Nice idea.
What happens if the water is not 100% pure but 99 or 98 instead?
