In order to open a manhole cover and access the sanitary sewerage conveyance system, authorization is required from the Regional Wastewater Reclamation Department (RWRD).
Once you have submitted your application, the submission is routed electronically to designated staff, and you may proceed with access unless contacted by Pima County staff. RWRD reserves the right to revoke the de facto access permits for any reason.
RWRD hereby notifies the applicant that sewer manholes are hazardous environments and may contain hazards such as low oxygen, explosive vapors and gases, high hydrogen sulfide, falls, pathogens, and hazardous energy. Confined space entry is outside this process and requires specific RWRD approval.
