Aggregate Rock System

Aggregate rock drainage has been in use since Roman times. This means there is hundreds of years of success and knowledge of what works and what doesn’t.

First a Bed or Trench (drainfield) is dug in your yard. This must conform to the requirements of the Health Dept. permit. They are the ones that tell us what size it must be. However our over 40 years of experience gives us a pretty good handle on what size it should be.

In some cases a digout must be done and additional septic sand must be put into the hole. Generally the reason for this is because the Health Dept. inspector has found soils that are not compatible to drainfield use. All of this must be removed from the site and cannot be used for cover on the system.

After the hole is dug, we use lasers to make sure it is the correct depth and level. Our crew then installs the special patented pipe we use. We use patented clamps to suspend the pipe at the correct height off of the ground. Again lasers are used to insure level.

The crew then puts the rock (aggregate) into, and around the pipe. By state requirements it must be 6” below the pipe 4” besides the pipe and 2” above.

We use a conveyor type of truck to distribute the rock evenly under, around, and on top of the pipe.

We then cover the entire field with a special paper to keep sand and dirt from getting into the rock. We then call the Health Dept. again for a final inspection. Within a few days they will come out and check our workmanship.

Making sure we stayed the proper distance away from all wells, and that we built the system according to the permit requirements. During this process they check the width, length, depth and size of the system. If this passes and it generally does, they then issue a final order to cover.

Within a few days after getting this approval we will arrive and cover the drainfield and smooth it out. Making it ready for your sod and or landscaping designs.

 
Aggregate rock drain field after 10 years Dixie Septic Tanks
Aggregate Drain Field

One of our systems we opened up for inspection after 10 years in use.

Please note the fabric paper is still above the rock and everything working as designed. The drain field is in perfect shape after a full decade of use.

One of the competitors systems is designed for the water to run directly into the pipe or chamber and drop directly into the ground on one end. They do not use rock for the water to dissipate through; it goes directly into the soil. This saturates the soil a whole lot faster in one place and can create premature failure of your system. Water does not pass through soil as fast as it does in a rock system. It actually forms a large pond or lake of contaminated water below your grass.

They advertise that the chamber systems stores up to 40% more water than the aggregate (rock) systems. Why would you want a large pond as mentioned above of septic water in your front yard?

The ideal way is to filter the water through the rock (just like the Romans did) before it passes down into the soil. Not to store it in a cavernous chamber.

Stacked Pipe System Another system on the market is an all pipe system. Here water passes from one pipe into another pipe below it, before going directly into the soil below. They are replacing the extra stacked pipe for rock. These systems do not properly dispurse water.

Dixie Septic Inc. is happy to quote you. We can supply more information regarding the maintenance of your system and other useful hints after you become our customer.

This system was only 3 years old.

A third competitive system uses pipe encased in a netting holding Styrofoam peanuts. Here the water flows out of the pipe through the foam peanuts directly into the soil. Imagine if you will what happens when the foam is saturated with water? It collapses. Again no rock is used for filtering.

Why are these alternative systems so popular? The only reason is because they are easier to install. No heavy equipment is necessary other than digging the hole. The installer digs the hole, walks up and throws the pipe into the ground, covers it and walks away.
