I assume you are checking these spreadsheets out for interest. The latest date these will be law is June 2010.
I have been reviewing the updated laws and spreadsheets, but i have not tried to enter any info yet. I will give it a try.
Does anyone have a guideline to hydrostatic testing a pvc pipe with air. We want to fill a gravity stormwater system with water and see how much infiltration / exfiiltration there is in the system. Anyone have a guideline for how much rise / fall is the water level we should expect?
Thanks
