Water and wastewater treatment
Unit processes and plant layout.
Use this add-on:
Screenshots and a short video come with the listing (AL.3).
Overview
Water and wastewater treatment is a planned add-on for CivilCraft and BimCraft (roadmap row CH.20). It is meant to hold the unit processes of a treatment plant (screens, clarifiers, activated sludge, filters and disinfection) with mass balances, and to link to the site and pipes in CivilCraft. It is not built as an add-on: no command, panel or listing page works today.
Who it’s for
- Civil and environmental engineers who size treatment processes and lay out the plant on a site (intended).
- Plant designers in BIM who want the process model beside the building model (intended).
What you can do
- Nothing works today: the add-on is planned. What is intended for row CH.20: unit processes (screens, clarifiers, activated sludge with the published ASM1 model, filters, disinfection), mass balances, and links to CivilCraft's site and pipes.
Methods and standards
The planned add-on sits on the process engine (engine.process). The engine already holds a water module in lib/process/env/water.js: the ASM1 matrix and rates, an activated-sludge plant of tanks in series with recycles, COD, nitrogen and oxygen balances, screens, an ideal settling basin, filter head loss, disinfection by contact time and site footprints. It is a library only and no app mounts it. WaterTAP is named in the plan as an engine option; the session log says its engine record is held and no script exists.
Data and sources
Planned: no data ships because nothing ships. The ASM1 parameter set in the engine is typed in the code and is listed in the session log as still to be checked by an engineer against the published report.
Verification
Not yet checked as an add-on: planned, no add-on test exists. The engine behind it has a test, tools/process-test/test-env.mjs, which the session log docs/0.8-sessions/chem-env_PART_3.md records as 206 passed, 0 failed on 2026-10-28. That log states the checks are against closed forms and published cases where it says so, and that the ASM1 benchmark values are not yet done.
Limits
Planned and not built. No host mounts the engine. Not built in the engine either, per the session log: the Takacs settler, temperature correction, ASM2 and ASM3, anaerobic digestion, membranes, chemical dosing, the CivilCraft command and WaterTAP. A calculation here would not replace a design by a licensed engineer.
Files and formats
Nothing yet. The plan is to link to CivilCraft site and pipe data; the file formats are not defined.
Get started
- This add-on is planned (roadmap row CH.20). Nothing is installed or switched on today.
- Follow row CH.20 in /roadmap-issues for its status.
- Until then the water module is a library only, with no command or panel in any app.
Languages
No languages are listed for this add-on yet. Its maker may add some.
