Underground Line Work in Bow Mar

Bow Mar is a small town of large lots between Denver and Littleton, and its underground reflects that. Most homes here were built from the 1950s through the 1970s on acre-scale parcels, which means long private sewer laterals and long water service runs with very few access points along the way. When something fails in Bow Mar, the hard part is usually locating it, not fixing it.

Areas we cover: Bow Mar, Bow Mar South, Marston Lake area, Bowles Avenue corridor.

Permits and Authority in Bow Mar

Water and sanitary sewer service in Bow Mar is administered through the Bow Mar Water and Sanitation District rather than through a big-city utility, so tap applications, connection standards, and inspections run through the district. Work that opens a roadway is coordinated with the Town of Bow Mar, and with Arapahoe or Jefferson County where a county road is involved.

We confirm the governing authority for your specific parcel before quoting, because the town straddles two counties and the boundary is not obvious from the address.

  • Water and sanitary sewer: Bow Mar Water and Sanitation District.
  • Roadway and right-of-way work: Town of Bow Mar, with Arapahoe or Jefferson County on county roads.
  • Parcel-level verification before any tap or connection quote.

Tap and Connection Notes

  • District connection standards and inspection scheduling govern taps here, not city utility procedures.
  • Long private runs mean the cleanout location decides how a repair is accessed. Where there is not one, adding it is usually the first thing we recommend.

Typical Pipe Eras in Bow Mar

  • 1950s to 1970s construction: cast iron and vitrified clay sewer laterals, with Orangeburg present in some late 1960s runs.
  • Copper water services from the 1960s onward, with some galvanized on the earliest homes.

How Lines Fail Here

  • Root intrusion along long laterals crossing mature landscaping.
  • Sags and lost grade in runs that cross irrigated lawn on shifting soil.
  • Cast iron corrosion at the foundation penetration.
  • Failures that are simply hard to reach because the lot is deep and cleanouts are scarce.
