About this service

A septic tank is an underground chamber where household waste is collected and partially broken down by bacteria. Solids settle to the bottom as sludge, while oils and fats float to the top as scum. The liquid in the middle eventually moves out into your drain field for final filtration. If the tank is not maintained, it can overflow or cause backups. We provide the regular inspections needed to keep your tank healthy. 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.
