Frequently Asked Questions

Q: What septic system is best?

A: There are three main types of septic systems. The best system for you depends on the size of your house, the condition, soil, slope and location of your property, the plant and ecological health of the surrounding area, and your future development and landscaping plans. We do a site visit, measure, and test, and talk with you before we design your new septic system.

Q: What can happen if a septic system is not professionally installed?

A: If a septic system is not installed properly, it can be disastrous. It can fail or collapse prematurely, leading to untreated wastewater contaminating groundwater, damaging your property and the surrounding area, and making people and animals sick.
