Question 1

What are the different types of septic systems?

Accepted Answer

•

There are a variety of different types of septic systems that can work in your home—such as conventional anaerobic systems, chamber systems, drip distribution systems and mound septic systems. All of them work using natural processes to break down solid waste and effectively treat wastewater without needing to be connected to a city sewer system. Which type of septic system you need will depend on characteristics of your property like how high the bedrock is or groundwater table is. Different types of systems come at different costs to install.

Question 2

What is a septic tank?

Accepted Answer

•

A septic tank is an underground container that collects and holds wastewater until it’s sufficiently filtered and broken down. It treats wastewater by separating waste so the leftover liquid can travel into the drainfield where the soil and gravel eventually filter and purify it. This process naturally eliminates bacteria, viruses, and other contaminants.

Question 3

Why do I need to drill a deeper well?

Accepted Answer

•

There are many reasons you may want to extend the depth of an existing well or drill a new, deeper well on your property. A deeper well can tap cleaner water sources—shallow water may contain more contaminants. With a deeper well, you’ll also have an easier time reaching the water table depth (the level at which underground water is found) and can get past tricky soil conditions.

Plus, if your local building code requires a minimum well depth for safety and environmental standards, you’ll meet the code by digging a deeper well in the first place.

Question 4

How deep should the drain field be under the ground?

Accepted Answer

•

Your drain field or leach field should be 1 to 3 feet under the ground. It will be a little shallower than the septic tank, although it can be the same depth or slightly deeper. The proper depth of the septic tank is up to 4 feet. It’s possible that your local regulatory agency requires a certain depth for your drain field.

Question 5

How do you install concrete septic tank risers?

Accepted Answer

•

Concrete septic tank risers are heavier and more durable than plastic or fiberglass ones, making them suitable for long-term use. Installing a concrete riser differs from installing plastic or fiberglass risers primarily in the materials and methods used. The process involves cutting the concrete risers to the required length and then stacking them, using concrete sealant or adhesive between sections for secure attachment. Due to their weight, extra care is necessary during leveling and the attachment of sections. Concrete sealant or adhesive may also require a curing before the riser is ready for use.
