Cleaning services involve the professional removal of sludge and scum that accumulates in your tank over time. We use specialized equipment to pump out the contents and ensure the tank is clear to prevent solids from clogging your drain field. You typically need this service every three to five years, depending on your household size and tank capacity. Regular cleaning is the best way to extend the life of your system. We provide 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 Washington

What is the cost of septic tank installation in Washington D.C.?

How often should a septic tank be inspected?

What does emptying septic tanks involve?

Emptying septic tanks in Washington, D.C., involves a specialist using a vacuum truck to pump out the accumulated solid and liquid waste. They access the tank via a manhole cover. The waste is then transported to an approved disposal facility. After pumping, the professional will often inspect the tank for any damage or signs of wear. This process is vital for preventing overflow and ensuring proper function.

What is the best toilet paper to use with a septic system?

The best toilet paper for septic systems in Washington, D.C., is septic-safe toilet paper. This type is designed to break down quickly and easily in the tank, reducing the risk of clogs. Avoid using thick, multi-ply papers, paper towels, or flushable wipes, as these do not decompose properly. Proper paper selection is a simple yet effective way to maintain your system.

How does a septic tank work?

A septic tank in Washington, D.C., functions as a primary treatment unit for wastewater. Solids settle to the bottom as sludge, and lighter materials like grease float to the top as scum. Bacteria within the tank help to break down some of the waste. The partially treated liquid then flows out to a drain field, where it is further filtered by the soil before returning to the environment. It's a natural process.
