Replacing your septic system requires careful planning before starting the project. Many considerations such as septic tank size, type and size of leach or drain field as well as the tank’s composition must be made. While your plumbing contractor will play an important role in designing and sizing the new septic system, you will be faced with important decisions during the process.
Type of Septic Tank
The number one decision most homeowners face during a septic tank replacement is which type to purchase, concrete or plastic. Listed below are the Pros and Cons of both plastic and concrete septic tanks.
- Plastic Septic Tanks
- Highly crack resistant
- Improper installation can cause the tank to pop or float to the surface
- Are susceptible to damage during installation
- Are not approved for use in some states
- Concrete Septic Tanks
- Maintain higher effluent levels versus plastic tanks
- Due to their weight, popping or floating to the surface is eliminated
- Concrete septic tanks are very durable and long-lasting
- Concrete septic tanks are approved for use in all states
- Concrete septic tanks are more expensive to manufacture and install
- Because they lack flexibility, they can crack under extreme circumstances
- Due to their weight, they are difficult to install and require heavy machinery
- Are susceptible to leaks due to cracking
Size of Septic Tank
The size of your septic tank will depend on several circumstances including the state you reside as well as the number of occupants in the household. Most municipalities will require both a soil test and water percolation test to determine the size and location of the septic tank and adjoining drain field. Most regulatory agencies will require a licensed plumbing or septic contractor carry out the tests.
The number of household occupants also carries a lot of weight in the septic tank size equation. The number of bedrooms in the house usually determines the number of its occupants. Commonly, one to three-bedroom homes require at least a 1000-gallon septic tank. In most cases, a four or five bedroom home would require up to a 1500-gallon septic tank.
Replacing septic tank system is a major home improvement project. It is important to hire a professional plumbing or septic contractor who is carrying the experience required for the project as well as the knowledge to install it correctly and legally according to the codes and regulations in your area.
