24 inches deep
Initially, PG&E wanted to bury the pipeline at a depth of 3 to 5 feet underground, which is what it does all over the state. The city wanted it buried 12 feet under grade to avoid conflicts with future city utilities such as sewer, water and electricity lines .
Gas service lines shall be installed at a depth so as to have a minimum of twenty-four (24) inches of cover. Customer-provided trench shall conform to company standards found in Appendix 1.
There is no allotted depth before a person needs to call 811 . Whether you are just planting small shrubs or installing fences, CGA says any time you are putting a shovel in the ground you need to call due to the fact that many utilities are buried just a few inches below the surface.
Gas lines are typically metal or plastic. If plastic, they ‘re very likely thick enough to withstand most hand digging with a shovel.
As part of customers’ gas service, PG&E representatives are available to inspect gas appliances and make sure they are working safely. To schedule an appliance safety inspection, customers can call 1-800- PGE -5000.
The natural gas pressure of the gas line leading to the home ranges from approximately 1/4 psi to 60 psi , depending on the number of homes or businesses served by the line . This compares to pressures of up to 1,500 psi for large-volume pipelines used to move the gas from the well fields to the local utilities.
Calling the 811 Hotline The best way to locate gas and other utility lines that are underground before you dig is by calling 811. When you make a free call to this federally designated number, your address, information on where you’re planning to dig and other information will be sent to any affected utility operators.
Yes in most jurisdictions you can . It’s a very good DIY project and it can be done very safely. First you need to obtain the proper permit. Install the piping with a pressure test on the pipe and get an inspection to approve the installation .
There has to be a shut-off valve at the connection to the rigid piping . This valve has to be in the same room as the appliance. Three- or six-foot long and accessible: The flexible connectors can ‘t go through walls , floors or ceilings, nor can they be concealed. For these appliances, 6 feet generally is allowed.
If trench is to be a joint trench (shared with other utilities ) the following separations must be maintained: 24 inches between gas and electric lines . 12 inches between water and electric lines . 24 inches between sewer and electric lines .
The law , in all states, generally provides that anyone excavating must call the 811 utility-locate hotline before digging begins to have all utilities located and marked.
811 : A Critical Safety Tool The electric, oil, gas, and phone/cable lines are owned by the utility right up to the meter, so these are covered by 811 . The water and sewer lines are public until you hit the property line; here they become private. 811 does not cover them after this point.
