I have conflict to resolve. Following my basic environmental impact research on sewer pipes, I would prefer to use HDPE based materials. The Chicago plumbing code, on the other hand, calls for cast iron soil pipe (CISP).
What options do I have? Well, none – other than applying for a plumbing code variance on environmental grounds.
My chances? Probably very slim. I hear through the grape vine that some forces in the Department of Water Management would like to update the plumbing code so that it better reflects sustainable building technologies. Others apparently don’t want any of it. Well, I guess it doesn’t hurt asking for a variance.
I wrote up my rationales on material performance, longevity and environmental footprint, included the carbon footprint calculations and sent it off to the Department of Water Management.
The Result? My variance request was denied. So far I have not received any reasons as to why, and I don’t know if I ever will. At least I tried.
The replacement sewers that will be installed under the basement slab will now be CISP. I decided to stop worrying about it. It may not be the perfect material, but I have been assured from many sides that it should outlive us. This is somewhat reassuring. But what about the next generation? Don’t they deserve some consideration?
