This notification is sent as both a notice and a reminder to the general contractors and plumbing contractors regarding the code requirements for the proper Installation of sewer connections and the protection of personnel during the installation. This notice and reminder
As per Volume I of the Public Facilities Manual (PFM), Section SS-14, sanitary sewer service connections are required to meet specific design and construction standards and criteria of specific concern are the locations where the lateral Is greater than 40" deep at the right-of-way. In these instances, the lateral is required to extend a minimum of 4' beyond the wye and extend upward to provide a maximum depth of 40". This allows the plumbing contractors to safely connect the building's sewer line at the proper depth. Please note that the connection shall be made to the pipe section extending beyond the wye. Connections are prohibited in the riser pipe to the cleanout (see attached standard per the PFM).
Please note, the safety requirements, as detailed by the Occupational Safety and Health Administration (OSHA), also apply during excavations and must be applied to protect employees during excavation activities to prevent cave-in by providing an adequate protection system. Please refer to OSHA Standard- 29 CFR, Safety and Health Regulations for Construction, Subpart Title- Excavations and Standard Number. 1926.6S2. Excavation work on sewer systems require the above noted OSHA protection systems unless they meet one of the listed exceptions such as excavations that are less than S' in depth and the soil composition has been examined by competent personnel that supports no potential cave-in.
Failure to adhere to the aforementioned PFM standards will result In a rejection of the inspection of the sewer connection and potential action by OSHA for violation of safety requirements.
If you have any questions regarding these requirements, please contact us at 382-6018 or 382-6401.
