About this service

When planning for a septic project, remember that you are paying for both the equipment and the labor. The tank itself is just one part; you also have to pay for the excavation, piping, and drain field installation. The total amount is typically influenced by the depth of the water table and the materials used for the tank. Getting a professional site assessment is necessary to understand your specific needs. Exact pricing confirmed free on the call.

Summer often means more houseguests and increased water usage, which puts extra demand on your septic tank. With more showers and laundry loads, it is easier for a tank to reach capacity. If you have guests coming over, consider a pump-out beforehand to avoid an inconvenient backup during your family gatherings.

Frequently asked in St. Paul

What is the purpose of a septic tank?

A septic tank is an underground wastewater treatment structure. Its main job is to collect all the wastewater from your home, like from toilets, sinks, and showers. The solid waste settles to the bottom as sludge, while lighter materials like grease float to the top as scum. This separation process helps to pre-treat the wastewater before it goes to the drain field for further treatment in the soil.

What is the average cost of a septic tank?

How long do septic tanks usually last?

A properly maintained septic tank system can last for decades, often 20 to 30 years or even longer. Regular pumping and maintenance are crucial to extend its lifespan. Ignoring signs of trouble or skipping inspections can significantly shorten the life of your system. Investing in routine care protects your St. Paul property.

How often do septic tanks need to be emptied?

Generally, septic tanks in the St. Paul area need to be pumped every 3 to 5 years. This depends on the size of your tank and the number of people living in your home. If you have a large family or notice slow drains, you might need more frequent pumping. Regular pumping prevents sludge and scum buildup, which can cause system failure.

How much does it cost to have a septic tank pumped?

The cost to pump a septic tank in St. Paul depends on several factors. These include the size of your tank and the accessibility for the service vehicle. Many factors can influence the final price.

How often should a septic tank be pumped?
