Understanding Water Percolation (Perc) Testing in Reno, NV
When planning new construction, septic system installation, or land development in Reno and the surrounding areas, one of the most critical steps is ensuring the land can properly handle wastewater. That’s where water percolation (perc) testing comes in—and at Carnes Engineering, we specialize in providing accurate, reliable perc testing to support safe and successful projects.
What is a Perc Test?
A percolation test, commonly called a “perc test,” measures how quickly water drains through soil. This is especially important for properties that plan to use a septic system, as the soil must absorb and filter wastewater safely without causing drainage issues or environmental risks.
In simple terms: if the soil can’t handle water properly, the land may not be suitable for a septic system—or it may require engineering solutions to make it work.
Why Perc Testing Matters
In Nevada, and especially here in Washoe County, soil types vary dramatically. Some areas have sandy, well-draining soil, while others contain clay that holds water. Perc testing ensures that:
Septic systems function properly without overflow or contamination.
Local health and environmental codes are met.
Property owners avoid costly surprises during construction or real estate purchases.
Engineers and contractors have the data they need to design effective wastewater systems.
How Carnes Engineering Conducts Perc Testing
At Carnes Engineering, we follow a careful, science-based process to deliver accurate results:
Site Evaluation – We assess the property to identify the best test locations.
Test Hole Preparation – Holes are dug at specific depths to simulate where a septic system would disperse wastewater.
Water Infiltration Testing – The holes are filled with water, and we measure the absorption rate over a set period of time.
Analysis & Reporting – Our engineers provide a detailed report that meets county and state requirements, helping guide next steps for design and permitting.
Local Expertise You Can Trust
Because soil and environmental conditions in Northern Nevada are unique, working with a local engineering team is essential. Our experience with Reno-area geology, water tables, and regulations means you’ll get results you can rely on.
