Whether you need an installation, pumping or repair – count on Gillis Construction to get the job done right.

How to Choose a Septic System

There are a wide variety of systems out there. How do you know which is right for you property? Our experts will walk you through each step of the process to find the right system for your needs and budget. Considerations include:

Type of Tank The environment around your septic system, i.e. whether you have gravelly, sandy or clay soil will be important indicators as to which type of tank you should choose. Ideally, sandy, well-drained soils are best.

Type of Pump The pump performs the task of ensuring no blockage ends up in your septic system. Do you want a more expensive and often more reliable turbine pump or a more affordable centrifugal? We’ll help you decide.

Size of Tank This is largely dependent on your home or business’s daily water usage. You should opt for a tank that is at least 1,000 gallons – but keep in mind the larger the usage, the larger the tank should be.
