I'm currently working for Pima County on the facilities side and trying to get into wastewater once my probation period is complete. I was hoping to get some references for study material for Wastewater Collections Cert 1, at the moment i'm looking at purchasing a course off of AWC. Up to this point I have been studying free content online, I just want something structured to study from. Would appreciate any advice, thank you in advance.
