"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."

"We got our working tank water heater replaced, it was 14 years old so about end of life. Due to COVID they asked for photos via text message, gave quote for exact product, suggested that expansion tank is on wrong side (we never knew), came on time, got the products, fixed the expansion tank and were done in less than 2 hours. Asked to clear the garage, maintained social distance, job perfectly done."

Septic Tanks questions, answered by experts

There are a variety of different types of septic systems that can work in your home—such as conventional anaerobic systems, chamber systems, drip distribution systems and mound septic systems. All of them work using natural processes to break down solid waste and effectively treat wastewater without needing to be connected to a city sewer system. Which type of septic system you need will depend on characteristics of your property like how high the bedrock is or groundwater table is. Different types of systems come at different costs to install.

The average three to four-bedroom home typically uses a well pump rated for 8 to 12 gallons per minute (GPM). To find the most accurate size for your specific needs, a common rule of thumb is to count the number of water fixtures and appliances in your home and aim for that number in GPM. This calculation allows for about one gallon of water per minute per fixture. Because estimating the correct size can be challenging, it's best to have a professional technician make the final determination. A professional can ensure your pump provides sufficient water for your home, especially during peak usage hours.

Drain fields often include three to five trenches that are 18 to 24 inches deep. The pipes connecting the drain field to the septic tank will be placed between 12 and 18 inches deep, and the field as a whole will be about 100 feet long.

While dry wells can be effective for managing rainwater, they have several disadvantages. They can become clogged with sediment, especially after large storms, which reduces their effectiveness and can be difficult to clean. Dry wells are also not suitable for all soil types; they will not function properly in soil with low permeability. Additionally, if a dry well is not large enough to handle the amount of rainfall in your area, it can overflow. For gravity-flow models, the water may disperse very slowly, depending on the well's depth and the soil's permeability.

The purpose of a septic tank is to allow solid wastes to separate out of the wastewater using time, gravity, and other natural biological processes. If your septic tank is too small, it might be overwhelmed by solid waste and unable to accomplish this task—and if it’s far too large, there won’t be enough liquid in the tank to nurture the necessary bacteria to aid in the breakdown process.
