Trust Experts to Recommend the Right System

There’s a big difference between Westfall Septic Installation and a general contractor who occasionally installs a septic tank. With recent improvements in home septic technology and changing septic regulations, choosing Westfall  gets you proven expertise and integrity and the latest advances in the industry. We know the rules and we build according to them. This means your septic system will meet state and municipal requirements and will operate at the greatest efficiency.

Westfall Septic Installation will determine the optimum system and related components for your household, your property configuration, and your budget.

In addition to installing tanks, we also manufacture precast concrete tanks for residential and commercial use.

Westfall Septic Installation has extensive experience working with homeowners and contractors to design and install new septic systems or to repair or replace failing systems. We handle everything, including permits and always FREE estimates.

For septic tanks, concrete is a superior material to fiberglass and plastic. It’s watertight and heavy duty, making it ideal for both residential and commercial systems. Concrete tanks are more durable than fiberglass and plastic and their strength increases over time. What’s  more, concrete resists buoyant forces better than other materials – a real benefit in areas with high ground water like parts of Umatilla County. Lastly, concrete is an environmentally sound material and doesn’t add chemicals to the ground.

Westfall Tank and Excavation manufactures precast concrete septic tanks of several sizes and configurations, approved by the Oregon DEQ:

  • 500 gallon and 1,000 gallon dosing tanks
  • 1,000 gallon septic tanks
  • 1,500 gallon two-compartment septic tanks
  • 1,500 gallon two-compartment septic/dosing tanks
