Durango septic & civil engineering
La Plata County acreage, water rights realities, and long-haul off-grid builds.
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
