Frequently Asked Questions about Septic Systems & Design:

Q: What is a septic design?

A: A septic design is a set of site plans and construction details to build an onsite wastewater system. The plan accounts for soil conditions, topography, the buildings, and future serviceability. We also handle the plan submittal and communication with the Health Department.


Q: What Causes Septic Systems to Fail?

A: Common reasons Septic systems fail are - garbage disposals, high grease levels, leaky toilets or fixtures, high water use, doing all laundry in one day and certain types of medication. Female hygiene products should be wrapped in a plastic bag and put in your household trash. If you believe your septic system is failing, please contact a certified Septic System Designer immediately for recommended plan of action.


Q: How do I know if my Septic System is failing?

A: A septic tank should be pumped every couple of years. If there is water backup in your household then it is a good sign your septic system is failing. If wet spots or pools of water are starting to appear where your drainfield is, then that is also a sign there is a problem with your system. Another way to tell something is wrong with your drainfield is how it smells. Some odors will escape into the air but it should not saturate the area. If the area around you drainfield or where your tank is located has a very strong odor of human feces, then it would be a good idea to have your septic system inspected by a professional to detect any possible problems.


Q: How much does it cost for a septic system to be designed?

A: Cost varies depending on complexity of the system, location, type of facility served, etc. We can provide an estimate in a few minutes using our Geographical Information System, our large database of past jobs throughout the region, and with the Health Department’s database available on-line.


Q: What does it mean to perk my site?

A: This is an outdated term that really refers to having a septic system designed and approved by the local health department. Historically, a water percolation test was performed on every proposed building site. Given the large amount of historical percolation data, these tests are no longer necessary.


Q: How does soil effect my septic system?

A: After the treated waste leaves your septic tank and enters your drainfield, it should be relatively clean and free of biotic's. The water must be absorbed into the earth at a calculated rate based on how much water a household uses. There are formulas used to figure out how many gallons of water will be absorbed by each square foot of certain types of soil. If it takes a long time for your soil to absorb the water, then the drainfield must be larger to disperse all the water in a certain period of time. There will be more material and installation required for a larger drainfield. The type of soil that your property contains will make the installation and material fees vary to a degree. One of the items a Septic Designer looks at is what type of soils you have across your property and how deep the layers are. When test holes are dug, it gives an accurate idea of how your septic system needs to be designed for the house that is constructed or going to be constructed and how large your system needs to accommodate all the calculated water usage.
