How do I get the water line blueprints for our apartment complex in Oklahoma CityWe are having some waterline problems and need to know how to get the layout of the waterlines. We are an apartment complex in Oklahoma City. I contacted the City of OKC and talked to the Engineering Dept. They suggested I called the Building Permit Dept. They could not help me out either. Our apartments are approximately 30 years old. We have hit a deadend!! Who can I contact to get the blueprint of our waterlines?
