Signs You Need a New Septic System
When component repair is no longer viable, installing a modern engineered system permanently protects your property.
1. System Age Exceeding 25–35+ Years
Older gravel-and-pipe leach trenches eventually develop permanent biomat soil seal-offs.
2. Chronic Surfacing Effluent & Odors
Wastewater pooling continuously in the yard even during dry Colorado summer periods.
3. Collapsed Concrete or Steel Tank
Severe structural corrosion in pre-1980 single-chamber concrete or steel tank shells.
4. Home Additions & Bedroom Expansions
County health code mandates increased septic tank capacity when adding bedrooms.
5. New Home Construction on Rural Acreage
Complete virgin site design, setback planning, and soil perc-matched installation.
Septic System Types We Design & Install
We match system design strictly to your soil percolation rates, groundwater depth, and county code:
Conventional Gravity
Effluent flows naturally by gravity into underground gravel or chamber trenches. Best for well-draining soils with deep water tables.
Engineered Sand Mound
Elevated sand filtration bed designed for properties with shallow bedrock, heavy clay soil, or high seasonal water tables.
Pressure Distribution
Uses timed pressure dosing pumps to distribute effluent uniformly across all lateral lines simultaneously.
Advanced ATU / Drip
Aerobic treatment units and sub-surface drip irrigation for environmentally sensitive lots or tight property setbacks.
