The time to replace that old septic tank is finally here. Before settling on your next unit, understanding the range of septic tanks available is essential. A well-engineered septic tank can last several years. It’s critical that you choose the right septic tank for your needs and follow the prescribed maintenance schedule. At the end of the day, this can save you thousands.

The design of your septic tank is tied to a diversity of factors. Aspects to consider as you pursue your next septic tank are as follows:

  • Household size
  • Soil type
  • Lot size
  • Local water bodies
  • Climate conditions
  • Environmental safety
  • Regulatory concerns

Different Types of Septic Tanks

As an owner of a septic tank, you’re probably already aware of its principal design and primary function. To review, however, a septic tank is essentially a watertight container that holds and partially treats domestic sewage and wastewater.

The tank acts as a wastewater filtration medium. Septic systems are specifically engineered to separate heavier solids (sludge) at the tank’s bottom while lighter solids, such as greases and cooking oil (scum), drift to the top. In a properly functioning tank, the wastewater is discharged and dispersed to a drainfield. The water undergoes another filtration process before it is recycled back into the local water table.

As for the various types of septic systems, the design of each is meant to serve a function specific to the factors mentioned above and listed below:

  • Conventional
  • Mound systems
  • Evapotranspiration system
  • Recirculating sand filter system
  • Aerobic and anaerobic system
  • Drip distribution system
  • Constructed wetland system

We recommend that you consult with a professional and verify local environmental regulations and restrictions before investing in any new septic tank. Most homeowners, however, will be searching for either a conventional septic system or an anaerobic treatment unit. Aerobic systems are considerably more complex. We’ll get into them a bit below in our discussion about costs.

Conventional Septic System vs Anaerobic Treatment Units

A conventional system is what’s found in the vast majority of residential homes and small business sites. The downside to them is they leave a relatively large footprint, and they may not be suitable for all locations.

Conversely, if your home is situated on a smaller lot, an Aerobic Treatment Unit (ATU) may be deployed to counterbalance less than desirable considerations at the site such as inadequate soil, higher water tables, or a home that’s too close to a sensitive body of water that your system could potentially contaminate with wastewater bacteria.

The Final Takeaway

New septic tank installation is not your typical weekend warrior’s task. Remember to consult with a trusted professional before making any final decisions on your next system. And once you’ve made that decision, be sure to follow the proper maintenance protocol to extend the useful life of your new septic system. Reach out to us at Dan’s Drains & Digs for more information.
