The use of a concrete septic tank is an efficient way to contain wastewater generated from faucets, showers, washrooms, and toilets in your home. This is usually found in rural places that lack more modern sewage systems. Concrete septic tanks come in different kinds, with a length of about nine feet, and are used to segregate the water from the solids in waste generated from households. The water is drained using a filtering drain field, as the solids stay at the bottom and are pumped out regularly.
The most popularly used kind of septic tank, which is the concrete septic tank, is the easiest kind to install as well as the most affordable. The two kinds of concrete septic tanks are the poured septic tank and the precast septic tank. The poured tanks are easily destroyed depending on weather conditions and the environment it is surrounded by. These tanks can last for many years, but the cracks that lead to leaks can form and greatly affect its quality. The precast tanks are more durable and do not crack as easily over time. They are, however, more difficult to install. Here are a few common concrete septic tank issues.
1. The Cost of Concrete Septic Tanks
Installing a concrete septic tank is costly compared to plastic septic tanks due to their weight. It requires the help of big equipment such as a crane. The nationwide costs of such a tank average $3,000 to $5,000; however, it may amount to $15,000 or more depending on the area, soil condition, area building codes, and the kind of tank that is being installed.
2. Cracking of Concrete Septic Tanks
Cracking is usually experienced with concrete septic tanks when heavy vehicles run them over. Cracks in the tank occur if the kind of concrete used for the tank is of poor composition. From the cracks, leaks can occur and damage the soil around it. Damaged soil may become a risk to health.
3. The Weight of Concrete Septic Tanks
Concrete septic tanks are heavy which makes installing and transporting these tanks difficul. A concrete tank with a capacity of 500 gallons weighs about 8,000 pounds, which is much heavier than a 450-pound plastic tank.
Advantages of Concrete Septic Tanks
There are advantages to using concrete septic tanks. Their effluent level is higher compared to those made of plastic. Concrete septic tanks are also tougher and they last much longer compared to other types of septic tanks. Concrete septic tanks do not float due to their heaviness. A number of municipalities require concrete septic tanks.
Disadvantages of Concrete Septic Tanks
Though having a concrete septic tank is cost-effective, concrete septic tanks can also experience some problems. Concrete septic tanks easily deteriorate due to sewer gases which overtime corrodes the concrete. Concrete is more easily affected by tree roots that penetrate the tanks. When a tree root penetrates a concrete septic tank it can break apart the concrete and damage the concrete septic tank entirely.
