About this service
Concrete tanks are the most common type because they are heavy, durable, and resist shifting underground. Over time, the concrete can crack or degrade from chemical exposure, which might lead to leaks. If your tank is older, a pro should check for cracks during routine maintenance. The cost of repair or replacement depends on the tank size and excavation 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 Thornton
What is a septic tank and its function in Thornton?
A septic tank in Thornton is an underground, watertight container that receives wastewater from your home. Its primary function is to separate solids from liquids. The solids settle at the bottom as sludge, while lighter materials like grease float to the top as scum. The partially treated liquid then flows out to the drain field for further treatment. This system is crucial for homes not connected to municipal sewer lines.
