What’s the Difference Between Septic and City Sewer in Arlington, TX?

For homeowners and business owners in Arlington, Texas, the efficient and safe disposal of wastewater is a fundamental concern. While often an invisible process, the system responsible for carrying away our used water and waste is a critical piece of infrastructure. In Arlington, properties rely on one of two primary methods: private septic systems or connection to the city’s public sewer network. Understanding the distinct characteristics, responsibilities, and potential needs of each system is essential for property owners to ensure proper maintenance, identify potential issues, and make informed decisions about their wastewater management.  

The Independent Operation of Septic Systems:

In areas of Arlington that are less densely populated or located outside the reach of the municipal sewer lines, private septic systems are the standard. These are self-contained wastewater treatment facilities designed to handle the wastewater generated by a single property. A typical septic system comprises two main components: the septic tank and the drain field (also known as a leach field).  

• The Septic Tank: Initial Treatment: Wastewater from your Arlington home or business first flows into the septic tank, a buried, watertight container. Here, the natural process of separation begins. Heavier solids settle to the bottom, forming a layer of sludge, while lighter materials like grease and oils float to the top, creating a scum layer. Anaerobic bacteria present in the tank start to break down these solids. The partially treated liquid effluent, now with reduced solid content, then moves on to the next stage.  
• The Drain Field: Final Filtration: The effluent exits the septic tank and enters the drain field, a series of shallow, underground trenches lined with gravel or other porous material. This network allows the wastewater to slowly filter through the soil. The soil acts as a natural filter, removing remaining impurities and harmful bacteria before the treated water eventually percolates into the groundwater.  
• Homeowner Responsibility: For properties in Arlington utilizing septic systems, the onus of responsibility for their proper functioning and maintenance rests entirely with the property owner. This includes crucial tasks such as regular septic tank pumping (typically every 3 to 5 years, depending on usage and tank size) to remove accumulated sludge and scum. Neglecting this can lead to system backups and costly repairs. Owners must also be mindful of what enters their drains, avoiding the disposal of grease, harsh chemicals, and non-biodegradable items that can harm the system’s delicate microbial balance and clog the drain field. Furthermore, proper landscaping and avoiding heavy traffic over the drain field are essential to ensure its continued effectiveness.  

The Connected Convenience of City Sewer Systems:

In contrast, properties within Arlington’s more developed and urbanized areas are typically connected to the city’s public sewer system. This is a network of underground pipes that collects wastewater from numerous homes and businesses and transports it to a centralized wastewater treatment plant managed by the municipality.

• The Lateral Line and Main Lines: Wastewater from your Arlington property flows through a private lateral line, which connects to a larger public main sewer line, usually located beneath streets or within public easements. The city of Arlington is generally responsible for the maintenance and upkeep of these main sewer lines.
• Centralized Treatment: The wastewater collected through the city’s sewer network is conveyed to a treatment plant. Here, it undergoes a multi-stage process to remove pollutants and contaminants before the treated water is discharged into local waterways, adhering to environmental regulations.
• Shared Responsibility: When connected to the city sewer in Arlington, the responsibility for the wastewater system is shared. The property owner is typically responsible for maintaining the private lateral line that connects their property to the public main. The city takes on the responsibility for the main lines and the operation of the treatment plant.
• Monthly Fees: Property owners connected to the city sewer in Arlington typically pay a monthly service fee as part of their water bill. This fee helps fund the operation, maintenance, and upgrades of the public sewer infrastructure.
