Types of Sewer Systems: Exploring Options for Your Property
When it comes to sewer systems, there are various options available to suit different properties and needs. Choosing the right sewer system for your property is essential for proper wastewater management and the smooth functioning of your plumbing. If you are considering a sewer installation or upgrading an existing system, it is crucial to explore the different types of sewer systems available and select the one that best fits your requirements.
Public Sewer Systems
Public sewer systems, also known as municipal sewers, are the most common type of sewer system in urban and suburban areas. These systems are owned and maintained by local government entities and provide a centralized wastewater management solution. Public sewer systems connect multiple properties to a network of underground pipes that transport wastewater to a treatment plant. Choosing a public sewer system means relying on the local municipality for the management and maintenance of the sewer infrastructure.
Private Sewer Systems
Private sewer systems, also referred to as septic systems, are commonly used in rural and remote areas where public sewer systems are not available. A private sewer system consists of a septic tank and a drainfield. Wastewater from the property flows into the septic tank, where solids settle and bacteria break down the organic matter. The clarified liquid then drains into the drainfield, where it percolates through the soil, undergoing further treatment. Private sewer systems require regular maintenance and periodic pumping to ensure proper functioning.
Alternative Sewer Systems
In certain situations, alternative sewer systems may be utilized to address specific site conditions or environmental concerns. These systems include options such as aerobic treatment units (ATUs), mound systems, and pressure distribution systems. Alternative sewer systems employ advanced treatment technologies to process wastewater and reduce environmental impact. They are commonly used in areas with high water tables, poor soil quality, or stringent regulatory requirements.
Combined Sewer Systems
Combined sewer systems are found in older urban areas and are designed to collect both wastewater and stormwater in a single system. During dry weather, the wastewater is transported to a treatment plant. However, during heavy rainfall or snowmelt, the capacity of the system may be exceeded, leading to combined sewer overflows (CSOs), where untreated wastewater is discharged into nearby water bodies.
