A Caldwell Septic Company and You

Most homes without access to the city sewer treat their waste using a home septic system. A properly installed and maintained septic system from a professional Caldwell Septic Company protects groundwater quality and treats wastewater wherever city sewer service is not possible. The septic tank and the drain field are the two parts to a septic system.

Approximately 25 million homes across the US rely on their septic tank to treat their home wastewater. A Caldwell Septic Company can design, install, and maintain your septic system to keep it at optimum functionality. When a septic tank works properly, it is extremely effective in protecting the health of your family, and the environment.

With proper care and regular maintenance from a Caldwell Septic Company, your septic tank will last for years. Each septic tank is custom-sized to the household, and needs to be kept free of harsh chemicals to operate at maximum efficiency.

How a Caldwell Septic Company Works on Your Tank

A Caldwell Septic Company has years of experience in septic cleaning and septic system maintenance. Their understanding of your septic system is backed up by this extensive work history. However, it's important for you as a homeowner to understand how your septic tank works, even if professionals from a Caldwell Septic Company will be maintaining it for you.

Even though every septic system is slightly different, the manner in which each septic tank works is the same. Wastewater from your house is carried into the septic tank by gravity. The tank holds this wastewater for one or two days, during which time anaerobic bacteria inside the tank break down the substances in the water. These bacteria separate the wastewater into solids, greases, oils, and floating substances.

While bacteria inside your septic tank will do a fine job of breaking down your home's wastewater, the professionals from the Caldwell Septic Company know it can't dissolve everything. In every septic tank there is a layer of 'scum' floating at the top, in the middle there is a layer of partially treated or "grey" water, and heavy, thick sludge lines the bottom of the tank. All three layers must have a sort of internal "equilibrium" to them, which your Caldwell Septic Company can help control, in order to continue functioning the way a septic system should.

After remaining in the septic tank for one or two days, the "grey" wastewater inside the tank flows into the drain field. The drain field is a series of perforated pipes inside a trench filled with sand, gravel, tire chips, or other loose yet dense material. Your drain field will be regularly evaluated by the Caldwell Septic Company as its health and condition is very important for the good performance of your septic system.

The wastewater enters the soil, after flowing out of the holes, along the pipes. This soil acts as a natural filter for any remaining waste products in the water. The toxins, bacteria, or viruses in the wastewater are broken down by the microorganisms and the oxygen in the soil. When functioning properly, a drain field allows a septic tank to contribute clean, potable water back into the surrounding area's ground water table. Your Caldwell Septic Company can ensure your drain field is working as it should.

As this water may have come from a toilet, sink, washing machine, or shower, there is a wide variety in the types of debris found in the wastewater. Most of these can be handled easily by the bacteria already inside the septic tank. In case of a clog or septic back-up, the Caldwell Septic Company is always available.
