How deep does PVC pipe need to be buried?
This measurement is from the top of the pipe to the surface of the soil, which means your trenches must be slightly deeper to accommodate the pipes. For example, if you're using a pipe with a 2-inch diameter and you want it buried 10 inches below the surface, your trench must be 12 inches deep.
Dig 24 inches. At 24 inches you can bury underground feeder cable, using PVC conduit to 18 in. below ground only where the wire comes up. If you're considering running a power lineunderground through your yard, you have four options.
- 3. Electrical Wire Encased in PVC Conduit. The National Electric Code (NEC) sets the required burial depth of electric wire in rigid, non-metallic conduit, such as PVC, at 18-inches. Cable in any conduit, including PVC, that is buried at this depth is not in danger of being severed or disturbed by normal digging.

- THHN Wire. The most popular type is THHN wire. THHN stands for Thermoplastic High Heat-resistant Nylon coated. THHN can come in stranded or solid conductors depending on the size. It is either manufactured in copper or aluminum and covered in a PVC (polyvinyl chloride) insulation with a nylon jacket.
These wires are buried in a trench 24 inches deep when installed, measured from the top of the conduit or service wire to the top of the trench.
- Water lines must be buried a minimum of 6" below the frost line in order to keep from bursting. So this varies based on location. According to the international building codes, frost depth in Kentucky varies from 27"-33" inches. So it would be safe to bury lines to 40" below the surface in Kentucky.
- At 24 inches you can bury underground feeder cable, using PVC conduit to 18 in. below ground only where the wire comes up. If you're considering running a power lineunderground through your yard, you have four options. Your choice depends on how much power you want.
- I am installing a new water service and need to know how deep the trench should be for water service pipes? There is a minimum and maximum depth at which service pipes should be laid: Minimum depth is 750 mm. Maximum depth is 1350 mm.
Laying outside line. When you are digging the trench for your new waterline, be sure the waterline is 12-inches below the local frost depth, but in no case less than two feet underground.
- Often these regulations imposed an age limit on a manufactured home that could be relocated within a county. Counties frequently drew the line at 10 years, some as few as five years; any manufactured home older than the established age limit could not be moved into the county or relocated within the county.
- It usually costs between $2,000 and $5,000 to move a mobile home less than 100 miles, although it may cost as little as $1,000 in some circumstances. If you're moving a mobile home more than 100 miles, expect to pay $6 to $15 per mile or up to $15,000 in transport costs alone.
- How Much Does a Mobile Home Cost? Typical costs: The average sales price nationwide for a new manufactured home in 2007 ranged from $37,100 for a single-wide and $73,600 for a double-wide (not including land), according to an annual report by the Census Bureau and the Department of Housing and Urban Development.
