![]() NexGen creates recirculating sand system designs that allow for more treatment of effluent before it reaches the leach field. The wastewater is then dispersed into the leach field. One possible design is the sand filter septic system design, where wastewater is sent through a sand filter. Sand is an effective filter in septic system designs and can be used in achieving sustainability goals. This creates more distance between the effluent and the groundwater and allows the effluent to purify to an acceptable level before it reaches the water table. Once in the sand mound, the wastewater filters down, leaving impurities behind. Electrical pumps force wastewater into the mound. A mound of sand is built by NexGen with earth-moving equipment in the location of the leach field. This is typically used when the water table is close to the surface of the ground or if the soil is inappropriate for a typical leach field. Using Sand as a Filter in Septic System DesignĪnother possibility in alternative septic systems is the mound septic system design. This level of treatment is considered secondary treatment, and compared to a conventional septic tank, it’s faster. Effluent flows out and into the leach field. They are further broken down than they are in a conventional system. The bacteria present in the air (aerobic bacteria) break down the solids. In this system, waste flows into the tank, and air is forced into the chamber with the waste by pumps. NexGen has a solution called an aerobic tank. These solutions produce less environmental waste than conventional systems. There are also alternative septic system designs. Looking into Alternative Septic System Designs This system works on gravity and provides only primary treatment. A conventional septic tank has three levels: the bottom layer that has heavy solids, the middle layer that is filled with wastewater, or effluent, that is treated and flows into the leach field, and the top layer with lighter solids and grease that is also broken down by anaerobic bacteria. As the waste is broken down by the natural bacteria, it becomes wastewater. This method uses anaerobic bacteria (bacteria that do not need air) to break down the solids and other waste that enters the tank. One approach to water treatment that can be used is the conventional septic tank. Whatever the situation, we will use innovative approaches to engineering to find the perfect solution for your California septic system design. Choices can be based on what type of septic system you may want to have, such as an aerobic tank or leach field chambers, and in other situations, some options may be chosen because of water table height or unsuitability of soil on the site. NexGen offers choices in what kind of system you may use, from the type of tank to the type of leach field. When municipal sanitary sewer service is not available, a septic system is needed.
