One external factor that’s had a major impact on the size or capacity of septic designs is the regulations set in place by state and local authorities. Different states have different policies with regard to installation of septic containers and the steps that need to be followed hitherto.

Some authorities approve of smaller designs while others are totally of dissimilar opinion. However, most states have regulated the installation of septic tubs and made it mandatory for home owners to set up tanks that are not less than 1000 gallons in capacity.

Many people have supported this effort by the government, as the tank sizes are not only sizeable to hold waste matter conveniently but also suitable for a wide variety of applications. This means the model supports installation in homes and small scale businesses.

When setting up a new tank for use, it’s advisable that you contact a professional for aid. Notably, it’s also critical that you seek for advice from an expert from the start of the purchase throughout the installation and use of the tank.

The purchasing process that’s involved in the acquisition of septic tubs is completely different from the ordinary purchases you are used to. With a septic cistern, the advice from an expert will have a significant impact on the purchase you make.

Expert advice is cognizant of all the factors surrounding the installation, use and maintenance of a septic tank. Therefore, you can trust that the choice he or she impacts will prove to be beneficial in the long run.

  • Concrete

Designs made from concrete are very popular these days. They are strong and the indurated slab makes them tougher and enduring. Similarly, these designs barely break, even when a lot of pressure is mounted on top of their installed structures.

  • Double and single compartments

Most concrete designs are built either as double or single tanks. The single designs are the conventional types. With the inception of modernization, double compartments took over because of their efficacy in filtration and separation of waste.

Regardless, experts guarantee purchasers of either designs safe access to clean treatment plants. The inclusion of a pump in these systems makes it even better to eliminate waste and keep the tank working all year long.

Advantages and working criteria with concrete tanks

  • Heavy-duty

These tanks are heavily reinforced on the top surfaces to prevent any harm from breaking the structure and bringing it all down. The reinforcement ensures the tank remains intact and barely tears apart when bulldozers run through the top construction.

  • Installation

Basically, there are many requirements that ought to be taken into account during the installation of concrete designs.

To ensure you don’t make any errors that may prove to be costly as you set up the design, it’s imperative a qualified expert is called in to provide professional aid.

Contextually, concrete tanks are large and heavy owing to the size and nature of the materials that were incorporated into their construction.

Despite the ruggedness of most designs, installation of the tanks would require the use of complex equipment.

In case you don’t want to risk breaking a pricey concrete tank, it’s better that you consider picking fiberglass alternatives or plastic. Likewise, you can acquire these archetypes if you are in a location where it’s impossible to access heavy machinery.

It’s easier to install fiberglass and plastic cisterns because of the huge difference in their weight and size compositions to concrete designs.

  • Durability

This is a key feature manufacturers put into the concrete designs during construction. Durability is dependent on the quality of a model, so the stronger the model the higher the quality thus the better the reliability for years to come.

Concrete structures are often heavy and large. They are sealed throughout to prevent the exposure of contents through seams and cracks. To increase their strength and toughness, the tanks are reinforced with steel and meshes all round the structure.

With such additional fortification, the tanks stay strong and resistant to any external elements.

Types of concrete tanks

  • 1000-gallon

This is the standard model and is designed for 3-bedroom houses. Most states imposed regulations that made the 1000 quart tank the smallest design to be installed as part of a septic system in any residence.

  • 1250-gallon

It’s suitable for a 2 or 4-bedroom house. It’s heavy and sturdier compared to the 1000 design. When installing the design, a wire mesh is added all round the structure to give more strength and keep it stable for a long time.

  • 1500-gallon

The model is suitable for larger houses with 5-6 bedrooms. When setting up, you’ll be required to excavate deeply as it’s very large.

  • Presence of baffles

Baffles serve as inlets and outlets of waste matter. Through filtration, they separate scum and oils from effluents. Inlet baffles barely clog. Their designs slow effluents to ensure they’re broken down easily. They bar the entry to prevent gases from re-entering sewer lines.

Outlet baffles keep wastes within septic tanks. They prevent the mixing of solids and effluents. Besides, they make sure there’s zero contamination in the leach fields.

  • Plastic and fiberglass

The type of fiberglass or plastic tank you intend to purchase and install depends on the conditions of your location.

Plastic and fiberglass alternatives come in handy in circumstances where it’s harder to install concrete models. Here are some benefits that come with choosing a quality fiberglass or plastic option.

  • Mobility

These designs can be moved easily from the manufacturer to the place of installation. Unlike concrete tanks that require huge trucks and cranes, fiberglass and plastic cisterns are lightweight, easier to carry and install.

  • Cost-effective

The tanks are affordable and will cost you a significantly lower amount compared to when acquiring a concrete tub.

  • Durability

Concrete structures are made of hardened slab. They may give in to impact and pressure to crack or break open. Glass wool and synthetics don’t crack easily. Additionally, they won’t leak or get damaged due to pressure.

When installing the tank, ensure you have a professional nearby. This is because various factors need to be taken into account, for example, after installation, the professional should ensure nothing interferes with the top surface of the tank.


If there’s one downside to plasticized and filigree glass tanks, it should be buoyancy. In areas experiencing high rainfall, the water tends to lift and detach the tubs from their clips, leaving them floated and disseminating waste matter.

To prevent such an event from occurring, it’s advisable that you reinforce the installation with a slab on top, which paradoxically, is quite effective!
