If you need septic repairs or installation services on Oahu, turn to First Quality Environmental in Waimanalo. From conducting the initial design phase to performing regular maintenance on the completed system, their experienced septic tank contractors will make sure your system runs smoothly and efficiently. 

The first step in installing a new septic system is conducting a percolation test, which will determine the rate at which the soil in the potential septic drain field absorbs water. The technicians at First Quality Environmental need the results of the percolation test before they can design your new septic system. If the test does not return passing results based on the requirements for the state of Hawaii, installing a septic system in that particular location is not an option.

In order to conduct a percolation test, a septic tank contractor will typically dig at least three holes about 30 feet apart in the proposed leach field area. The holes will be approximately 2 feet deep and 6 to 12 inches in diameter. They’ll then place 2 inches of gravel or sand at the bottom of the holes and simulate the conditions of a working septic system by soaking the soil for several hours.

They will then measure how long it takes for the water to drop, and they will use this data to calculate the percolation rate, which is usually expressed in minutes per inch.

Conducting a percolation test is an important part of the initial septic system consultation because its results ultimately determine if the project will move forward.
