I am performing Life Cycle Assessment of wastewater treatment plant. I am trying to add inputs/outputs. however, the database is very limited. I am wondering what is the reason? For example, i am searching for wastewater and storm water as inputs but cannot any. Am I missing anything? Any help would be highly appreciated.

which database do you use? As you probably are aware of, you can search for waste water in Nexus, https://nexus.openlca.org/search/query=%22waste%20water%22. However, typically, if you model the  WW treatment plant anyhow, then you will have typically access to data for the plant, but need rather data for chemicals, electricity, maybe sewage treatment.

Yes you are right, the LCIA methods database contains LCIA methods (for ecoinvent, the original methods provided by ecoinvent, not our LCIA package).
