Durango septic & civil engineering

La Plata County acreage, water rights realities, and long-haul off-grid builds.

Ansom Outdoor currently holds PE licensure in CO. Final scope remains subject to the applicable authority and project requirements.

Southwest Colorado parcels are big, dry, and far from utilities. Water supply, storage, and wastewater are the design problem — and the answer usually involves a cistern, a well permit strategy, and an OWTS sized for intermittent occupancy.

We design onsite wastewater, water storage, grading, and access for La Plata, Montezuma, and Archuleta county properties, including full off-grid infrastructure packages.

What we design in Durango

  • OWTS design for large rural parcels and intermittent use
  • Cistern, hauled-water, and storage system design
  • Solar and off-grid utility infrastructure layout
  • Access road, culvert, and drainage design
  • Site feasibility for remote acreage
