Septic tank access covers are an essential component of a septic system. These covers are designed to seal and protect the openings of a septic tank to allow for maintenance and prevent hazards. They serve as a barrier to prevent surface water and debris from entering the tank, as well as to keep children and animals from accidentally falling in. If you’re looking to install a septic system on your property or upgrade an aging system, you’ll need to understand the role of septic tank access covers.

In this article, Garrett Precast walks you through everything you should know about septic tank access covers. We are a trusted precast company that manufactures and supplies a wide range of products, including septic tank lids, retaining walls, seawalls, lift stations, septic tank risers, and many more. Read on to learn more about septic tank access covers and where you can get high-quality concrete precast products.

Why Access Covers Are Important

The access cover allows licensed professionals to inspect the condition of your tank, check sludge levels, and pump out solid waste when necessary. Without it, any kind of servicing would require digging into the ground, which adds costs and hassle.

Access covers also provide an important safety feature. A secure and properly fitted cover prevents people or animals from falling into the tank and keeps odors and harmful gases from escaping into the yard. If the cover is broken, missing, or improperly sealed, it can pose serious safety and environmental hazards.

Types of Septic Tank Covers

There are several types of septic tank access covers, and the best one for your system will depend on local codes, your tank type, and environmental conditions:

  • Concrete Covers: These are very durable and heavy, providing excellent security and longevity. However, they can be difficult to lift without specialized equipment and may crack over time.
  • Plastic Covers: Lightweight and easy to handle, plastic covers are used with riser systems. They may not be as durable as concrete but are resistant to corrosion.
  • Steel Covers: Strong but susceptible to rust and corrosion over time. These are becoming less common due to durability concerns.

Cover Maintenance and Replacement

Like any part of your septic system, access covers require regular maintenance. You should visually inspect your cover at least once a year for signs of wear, cracks, or looseness. If the cover appears damaged or doesn’t seal properly, it’s essential to replace it right away to avoid safety hazards or environmental issues.

It’s also important to make sure the cover is always securely fastened or locked to prevent unauthorized access, especially if you have children or pets in the yard.

Upgrading with a Riser System

If your septic tank cover is buried, it may be worth upgrading to a riser system. Risers are vertical extensions that bring the access point to ground level, eliminating the need to dig every time your tank needs service. Most riser systems include a secure, child-resistant lid and are available in various materials to match your system’s needs.
