Why is testing soil percolation important?

Testing soil percolation is crucial for assessing soil absorption rates, which directly influences the design of on-site sewage disposal systems. When designing an OSSF, it is vital to understand how quickly water will move through the soil. This information helps determine the appropriate size and type of the sewage treatment system required for effective waste management. A soil that percolates too quickly may not adequately filter effluent, while one that percolates too slowly may lead to ponding and system failure. By conducting percolation tests, installers can ensure that the system is designed to match the soil's characteristics, promoting proper treatment and environmental protection.
