Water Infrastructure Service Providers | River Guides

Hey everyone, I'm looking for river guides / former operators in the Water Infrastructure industry (wastewater treatment specialists, 3rd party O&M utility service providers, water well maintenance / repairs, stormwater management, lift station repair technicians, alternative treatment system O&M providers, residential and commercial septic system providers etc.). If you have a good contact in any of these sub-industries, I would be grateful for an intro! I'm a traditional searcher based in Chicago (no geographic limitations). Happy to chat with other searchers looking in the Water industry as well, just shoot me a DM.
