Looking for regulations regarding grey water disposal (kitchen dish water and cleaning water) in a relatively remote environment in western Alberta, Canada. Specifically, can dish water and/or other cleaning water be emptied into an evaporation pit, or must it be plumbed in to existing septic tank? Would very much appreciate any help:).

Yes, there are new regulations. I could not copy the link for you but please visit Google under 'grey water regulations in Alberta'.

Your local utility board should help you.
