Septic Design

Excavators value our designs because it makes their jobs easier. They confidently bid the project because the system can be installed according to the design.  Homeowners also benefit from our designs because all the bids come from the same design.  Our carefully thought out design can considerably lower the installation price for both the homeowner and installer.  A good septic design must be accurate, easy to read, and economical. We design every system as if we were designing our own. 

With technology changing all the time water usage has been at an increasing rate.  With decreasing supplies of fresh water on earth it is critical that we give as much of this water back to the ground as we can. When it comes to designing a septic system we keep both you and the environment in mind.  Our goal is to design a system that is economical, require the least amount of maintenance, have a long life, and be beneficial to the environment. 

The two most common myths about a septic system function are that the septic tank treats the sewage, and that the soil filters the remaining particles creating pure water underground.

In fact the septic tank is basically a concrete box that holds roughly a few days’ worth of house hold sewage usage.  In the calm environment of the tank, dirt and solids settle and fall to the bottom. Grease and lighter particles from the sewage float to the top.  The septic tank works like a gravy boat delivering liquid sewage to the drainfield or leach field and storing solids and greases to be pumped out every few years. Numerous bacteria continue working to reduce some of the strength of the sewage, but not much treatment happens in the septic tank.

The separated liquid containing only water and the dissolved sewage solids, ("effluent") flows out of the septic tank through a pipe into the drainfield. Here it spreads over the floor of the drainfield.  This is where the real treatment takes place.  Billions of bacteria that live in the soil (30 million or so organisms live in a teaspoon of soil). The aerobic bacteria thrive in the area of the trenches and await the sewage effluent, which is their food source.  These creatures will consume all material leaving behind pure water.
