Over time, the solid layer of sludge at the bottom of the receptacle builds up, which decreases overall capacity and can lead to backups or contamination. Most cisterns need to be pumped every two to five years, depending on size and usage. This requirement can vary greatly from home to home, so be sure to have yours checked by one of our experts rather than relying on your neighbor’s advice. Proper tank care also includes maintaining a balanced bacterial environment. With the prevalence of antibacterial soaps and washes, it is imperative that an additive of beneficial bacteria is also incorporated into the sewage environment to promote natural solid breakdown. Our technicians can recommend a pumping and maintenance plan that is tailored around the size of your home and the capacity of your tank.
