The Superior Septic Tank Choice for Colorado Homes
First off. All concrete tanks are built to fail. This is due to microbial induced corrosion and hydrogen sulfide off gassing. They are a 20 year time bomb.
When you're investing tens of thousands of dollars into a new septic system, the last thing you want is the tank becoming the weakest link. At Land Systems West, we've installed and worked with nearly every type of septic tank available—from precast concrete to fiberglass and conventional polyethylene tanks.
After years of experience in Colorado's demanding soils and extreme freeze-thaw conditions, one product consistently stands above the rest:
The Roth HD MultiTank.
Whether you're building a mountain cabin in Leadville, a custom home in Douglas County, or a ranch in Elbert County, choosing the right septic tank can dramatically affect the longevity, reliability, and maintenance costs of your wastewater system.
What Makes the Roth HD Tank Different?
Unlike conventional plastic tanks that rely on a single wall, the Roth HD MultiTank is manufactured using a patented four-layer co-extrusion process consisting of a virgin HDPE inner layer, multiple structural polyethylene layers, and a UV-protected exterior layer. This construction provides exceptional structural strength while remaining corrosion resistant.
The result is a tank engineered for decades of dependable performance.
Key advantages include:
Multi-layer HDPE construction
Completely watertight design
No seams to crack or leak
Corrosion resistant
Lightweight yet extremely strong
Flexible installation options
Threaded watertight riser system
Lifetime corrosion protection warranty with additional labor coverage from the manufacturer.
Roth HD vs. Concrete for a Colorado Septic Tank
For decades, concrete tanks have been the industry standard.
Unfortunately, they also come with well-known long-term issues.
Concrete Tanks Can Deteriorate
Concrete is constantly exposed to hydrogen sulfide gas produced naturally inside septic systems.
Over time this gas converts into sulfuric acid that slowly eats away the concrete walls, baffles, and lids. This process—known as sulfide corrosion—is one of the leading causes of aging concrete tank failure.
Common issues include:
Cracked walls
Leaking seams
Corroded baffles
Water infiltration
Root intrusion
Structural collapse in older systems
Once deterioration begins, repairs are often expensive—or impossible.
Roth HD vs. Standard Plastic Tanks
Not all plastic tanks are created equal.
Many inexpensive polyethylene tanks are lightweight because they use thinner walls and simpler construction.
The Roth HD is engineered differently.
Advantages include:
Thicker engineered wall construction
Heavy-duty structural design
Multi-layer manufacturing process
Better resistance to deformation when properly installed
Greater installation flexibility
Larger service openings
Because the tank is engineered specifically for underground structural loading, it has become a preferred choice for many installers looking for a durable alternative to concrete.
Why Colorado Is Hard on Septic Tanks
Colorado presents some of the harshest installation environments in North America.
Land Systems West routinely installs systems in areas with:
Expansive clay
Rocky mountain soils
Freeze-thaw cycles
High groundwater
Heavy snow loads
Steep terrain
These conditions demand tanks that are watertight, corrosion resistant, and designed for long-term structural performance.
The Roth HD's cylindrical, seamless construction and engineered HDPE design help address many of these challenges when installed according to manufacturer specifications.

Easier Installation Means Better Results
One reason contractors appreciate the Roth HD tank is its installation efficiency.
Compared to concrete tanks:
No crane is typically required.
Less heavy equipment is needed for handling.
The low-profile design can reduce excavation depth in some applications.
No water is required during backfill according to the manufacturer's installation guidance.
Multiple inlet and outlet configurations provide flexibility in the field.
Completely Watertight Protection
One of the biggest enemies of every septic system is groundwater infiltration.
If groundwater enters the tank:
treatment efficiency can decrease,
pumps may run unnecessarily,
excess water can overload the drainfield,
operating costs can increase.
The Roth HD is designed as a seamless, watertight tank with gasketed pipe connections and threaded risers to help minimize infiltration and exfiltration when installed correctly.
Built for Long-Term Value
A septic system should last decades.
The tank should not be the component that limits the system's lifespan.
While every septic system requires routine pumping and maintenance, investing in a corrosion-resistant tank can reduce the risk of deterioration associated with concrete over time.
That is one of the biggest reasons Land Systems West specifies Roth HD tanks whenever project requirements and local regulations allow.

Frequently Asked Questions
Is the Roth HD tank better than a concrete septic tank?
For many homeowners, a Roth HD tank offers advantages such as corrosion resistance, watertight construction, lighter weight for installation, and a multi-layer HDPE design. Concrete tanks remain appropriate in many installations, but they can be susceptible to long-term sulfide corrosion.
How long does a Roth HD septic tank last?
With proper installation and routine septic maintenance, HDPE tanks are designed for long service life. Roth also provides lifetime corrosion protection on the tank and additional labor coverage under its warranty terms.
Does Land Systems West install Roth septic tanks?
Yes. Land Systems West installs Roth HD tanks where appropriate for the project and where they meet local code requirements.
Are Roth HD tanks approved in Colorado?
Approval depends on local and state regulations and the specific tank model. Land Systems West can help determine which approved tank is appropriate for your property's design and permitting requirements.
