Natural gas, water and sewer utilities are the normal underground systems for your home. These are typically placed in fairly straight trenches from the house to connections at the edge of the property or street.
If your electrical service is also underground it is likely to be in a separate trench. The wires will be in a conduit that runs from your meter to the nearest public utility pole or vault. If you have an underground electrical service, your cable TV and phone lines will likely be underground also. TV and phone cables are usually placed in separate conduits but placed in the same trench as the electrical service.
Another underground system is for drainage, although not every home has or needs one. Drainage systems collect water from around the perimeter of the home and move it safely away. Often these systems will daylight onto the street curb. Alternatively, they can empty into absorption pits, lower elevation outfalls or into sumps equipped with pumps to move the water to a safe place.
Call To Locate These Utilities On Your Property
- Before doing any digging on the site, check the location of buried services by calling 811, USA, the Underground Service Alert system. They will locate and mark any underground utilities, usually for free.
- Once the utilities are marked, map them out on a site plan to keep for your records so you know where they are for the future.
