About this service
These businesses use heavy-duty vacuum trucks to remove the buildup of solid waste and sludge from your tank. You generally need this service every three to five years, depending on your household size and tank capacity. By clearing out these solids, you prevent them from flowing into your drain field and causing expensive backups. Keeping your tank pumped on a regular schedule is the most effective way to extend the lifespan of your entire onsite wastewater system.
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.
