I find some variances between your variables and your units.
For example, I would expect "wastewater collected" to be a physical measure in liters/month, but it's dmnl. What does that mean?
Similarly, "water stored in dam" seems like an arbitrary transformation with unphysical units.
It seems like "water inflow" should be rain + wastewater reused, not rain*wastewater reused.

The wastewater collected variable seems OK, it's just the "water in dam" concept that seems to have no physical meaning.
I would expect something like:
wastewater collected = water supply * fraction water collected
