Caring for your septic tank
Septic Tank Maintenance
Septic tanks or treatment plants must be properly maintained. They should be cleaned on a regular basis to help with drainage and increase the life-expectancy of your tank. We recommend a clean and maintenance check every six months, to make sure everything is running smoothly. On average, a septic tank should be pumped clear of sludge every three to five years, however, some require pumping every year. If you are having issues with your septic tank, contact us today to arrange an onsite visit. Often, it is something as simple as extending the disposal area, or a quick maintenance check as opposed to needing a new tank installed.
