Septic Systems Explained Septic Systems are individual wastewater treatment systems that process small wastewater flows, usually from individual homes. They are typically used in rural settings where centralized wastewater treatment is impractical. Due to the new Massachusetts Title 5 regulations about wastewater disposal systems, and the fact that many towns and cities are installing centralized sewer systems, small septic systems will be phased out in favor of "city sewer" connections. Heider Construction is licensed under Title 5 to install and repair septic systems in locations where they are still "legal". We can also help you make the changeover from your old septic system to your city sewer when the time comes. There are many types of septic systems in use today. Every septic system is individually engineered for each particular site, but most septic systems are based on the same principles. A septic system consists of a septic tank, a distribution box and a drain field. They are all connected by pipes called conveyance lines.
Your septic system treats your household wastewater by temporarily holding it in the septic tank where solids and greases are allowed to separate from the raw wastewater. This separation process is known as the Primary Treatment. Most of the solids stored in the tank are decomposed by bacteria, and what can not be digested must be removed by a professional septic tank pumping service.
After the partially treated wastewater leaves the septic tank, it flows out and into a distribution box, which separates this flow evenly into a network of Drain Field trench pipes, sometimes called a leach field. Drainage holes at the bottom of each pipe allow the wastewater to drain into gravel-packed trenches for further treatment. This effluent slowly seeps into the subsurface soil where it undergoes final purification, or Secondary Treatment, by naturally occurring soil bacteria. A properly functioning septic system does not pollute the groundwater. Click here for tips in maintaining your system.
