We have seen several comments regarding the possibility (or not) to achieve both WEp1 and WEc3 through the use of on-site greywater and wastewater.

We have a manufacturing campus and are assessing a new office block within that campus.

I have a major renovation project that has existing plumbing fixtures that will remain.

If our project has three different kitchen sinks with varying flow rates (ie SK-1: 1.0GPM, SK-2: 1.5GPM etc), how do I enter the usage for the FTE in the project?

Hi! We have a data sheet from a shower which specifies a flow of 7,8 liters/minute at a pressure of 5.5 kgf/cm2 (which is equivalent to 5,39 Bar or 78 PSI).
