"My Septic pump had failed. I had already reached out to another septic repair company, but after 24 hours they still could not give me a day they would be available. I called Pavel at Earthworks Solutions and within 3 hours he had Dennis out there to replace my pump. He installed 3 risers and a new drainage pump all in the same day. Dennis did fast good work and I would recommend Earthworks Solutions."

"They answered the request for a quote immediately. Cory knew about the King County rebate program and told me about it. He walked me through the process and told me how much it would cost. Then he submitted the paperwork to register the septic inspection with the county. The job was completed to my satisfaction."

Septic Tanks FAQs, answered by experts

Septic tanks and cesspits are both types of sewage and wastewater systems, but they differ in key ways. The main difference between the two systems is that septic tanks separate sewage from wastewater and allow the latter to flow into a drainage field to filter and disperse into the soil. Cesspits don’t have outlets and instead, store sewage until it needs to be pumped by a professional.

A mound septic system, when properly maintained, can last between 20 and 25 years on average—though some last longer or malfunction sooner than that. The most important part of maintenance is getting an annual inspection of the vital parts of the system to ensure they’re in proper working order and not too backed up with sewage.

You may notice a septic smell in your yard after it rains if groundwater is entering your septic tank and causing it to overflow. If you experience septic odors after rainfall, contact a licensed plumber. They can construct a drain to redirect rainwater away from your septic tank. 

There are three layers of wastewater in a septic tank: scum (solid waste that floats to the top of the wastewater), liquid (the relatively clean liquid wastewater in between the two other layers), and sludge (solid waste that falls to the bottom of the wastewater). The buildup of sludge is one of the main reasons septic tanks need to be pumped. If the tank is more than 1/3 of the way full with a combination of sludge and scum, it’s time to call a pro for pumping.

If you notice that your well pump runs continuously, it’s important to take action quickly to avoid further damage. A few common issues may be to blame for a continuously running well pump, such as mechanical damage, a faulty pressure control switch, low water level, prime loss, and leaking pipes and fixtures.
