[Company] Leadership for years under hydration program created several locations housing ice makers; ice merchandisers; filtered water dispensers and water cooler sanitizing station.Yesterday [the gate] crew was seriously upset as aircraft maintenance team was working on [an aircraft] to clear clogged sewer line in aft; once maintenance team was done they walked to the sanitizing station at [an adjacent gate] meant for washing only drinking water coolers to wash their used tools. Even before [the] team could actually approach and prevent the act the maintenance team had already started the unbelievable act.Maintenance washed their dirty sewer tools and left. The act was reported to Supervisor on duty who reported to [operations] and Manager on duty about the act; who suggested to create a work order and have [facility maintenance] clean the sink which is not an acceptable solution to restore employee confidence and support [the company safety campaign.]  OSHA has set firm rules for these kind of bio hazard cleaning / removal / similar process and this act committed by maintenance team is clear violation and disregard to fellow employees well being.
