Hi all, For some background on our project: - we have on-site rainwater capture as well as connection to a municipal non-potable water supply - the municipal water is used to top up the rainwate

The documentation for WEp1/WEc3 submitted for this project indicated 5,000 retail customers per day visiting the Travel Plaza, utilizing the plumbing fixture usage rate of 0.2 uses per day as defin
