The best times of year to pump or empty a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access, and any snowmelt or rainfall can aid in proper drainage. Pumping before summer is also ideal to avoid conflicts with vacations or outdoor gatherings.

Fall is another great option, as contractors may be less busy than in the spring. Servicing the tank in late fall or early spring can also reduce the risk of overflow from extra precipitation during winter and spring.

While summer is a possibility, winter is generally not recommended. The ground is often frozen, which can make it difficult to access the tank, and the waste inside may also be frozen.

Cesspools do not have an outlet or discharge area, so they must be emptied regularly. A professional cesspool cleaning company should come at least every six weeks and empty the contents. If it’s not emptied, it can begin to overflow sewage waste onto your property.

Several things can ruin a septic tank over time, including dumping harsh chemicals (like bleach and ammonia), pesticides, and paint thinners down your drain because they can kill the bacteria in your septic tank. You should also make sure to only flush waste and toilet paper in your toilet—otherwise, you could clog your system.

You maintain a cesspool by pumping the tank every three to five years to prevent clogging. You should also have a septic tank or sewer system professional inspect the system once every three years. Avoid putting harmful chemicals and non-biodegradable items in the system to extend the life span of the cesspool.
