Your home's septic system is a miniature and personalized version of the waste treatment facility that your local city will have established. So it is important that you make the proper plans and follow the right installation process for your septic tank and drain field. Here are some recommendations when you are planning to install a septic system in your yard.
Select the Right Size Tank
One of the first steps in your installation of a new septic system is the size of the tank you should select. The larger your tank, the more effluent your septic system can handle, so if your household is larger, you will need to plan for a larger tank. Residential septic tanks can vary from an average of 750 to 1250 gallons.
However, you don't want to underestimate your needs and install a tank that is too small. It is better to install one that is a bit larger than you need so you have the capacity to handle waste water when the amounts increase. For example, if you have someone staying with your family for a time, it will increase the water waste from showers, laundry, and toilet flushing, which will put extra water into your tank. Go a bit larger on your tank size than your estimates of usage so you can have sufficient capacity when you need it later on.
Choose the Percolation Site
Another detail you want to account for is the location of your tank's drain field. This area needs to be further off from your home and the tank in an area that is not going to receive any vehicle traffic. Be sure it is not near your roof's drainage runoff from the gutters and downspouts.
The site also needs to be clear of natural waterways, such as a stream or river, and set back away from your vegetable garden and your neighbor's property. It is going to create a biohazard if you install the septic drain field next to your fence line if your neighbor has a vegetable garden growing just on the other side. Your septic installation professional can help you find a proper location for it.
Also be sure to look at the soil in the site of your drain field. It should be soil with good drainage that is free of clay or other loamy materials that prevent good saturation to the site. You can install a layer of gravel around the perforated pipes to aid in drainage and make the soil more conducive for septic drainage.
