What Are Sewer Systems and How Do They Function?
Sewer systems are underground infrastructure designed to collect, carry, and dispose of sewage and wastewater from residential, commercial, and industrial properties. These systems connect homes and businesses to large municipal wastewater services, where the water is treated and safely returned to the environment.
There are two main types of sewer systems commonly found in cities and communities across the U.S:
Sanitary Sewer Systems
Sanitary sewer systems are an essential part of modern infrastructure, designed to transport wastewater from residential, commercial, and industrial areas to treatment facilities. Unlike stormwater systems, which handle rainwater runoff, sanitary sewers exclusively manage wastewater from indoor plumbing fixtures such as sinks, toilets, and showers. These systems work through a network of underground pipes, pumping stations, and manholes, ensuring waste is efficiently transported without harming the environment or public health.
Proper maintenance of sanitary sewer systems is crucial to prevent blockages, overflows, and contamination of local water bodies. Issues like grease buildup, invasive tree roots, and improper flushing of non-biodegradable items can lead to costly repairs and service disruptions. Customers play a vital role in preserving these systems by following usage guidelines, such as avoiding the disposal of fats, oils, and wipes into drains.
Investments in sanitary sewer infrastructure not only enhance system performance but also protect natural resources and public well-being. Through regular inspections, maintenance, and community awareness, municipalities and property owners can work together to keep sanitary sewer systems reliable and effective for years to come.
Combined Sewer Systems
Combined sewer systems are a type of sewer infrastructure designed to collect both wastewater and stormwater in the same network of pipes. This dual-purpose system directs water from homes, businesses, and rainfall to a centralized treatment facility before being discharged into local water bodies. Combined sewer systems were historically implemented in older urban areas because they were cost-effective and efficient at the time of their construction.
However, during heavy rainfall or snowmelt events, the capacity of combined sewer systems can become overwhelmed, leading to a situation known as a combined sewer overflow (CSO). CSOs can result in untreated wastewater and stormwater being discharged directly into rivers, lakes, or oceans, potentially harming aquatic ecosystems and posing risks to public health.
To mitigate these impacts, municipalities have employed strategies such as constructing retention basins, upgrading sewer infrastructure, and implementing green infrastructure solutions like permeable pavements and rain gardens to manage stormwater at its source. Public participation also plays a role, as reducing water use during storms and properly managing runoff can help minimize strain on combined sewer systems.
Redesigning and modernizing combined sewer systems is a critical step in addressing environmental challenges and ensuring urban areas can handle increasingly frequent and intense storms driven by climate change. By combining innovative solutions and community engagement, cities can reduce the risks associated with combined sewer systems while maintaining their critical role in urban sanitation and water management.
To stay compliant, most municipalities work with agencies like the Environmental Protection Agency (EPA) to regulate proper sewer system construction, operation, and maintenance, protecting public health while ensuring environmental sustainability.
Why Sewer Infrastructure Matters
A city’s water and sewer infrastructure is an essential part of urban life. It supports everything from flushing toilets to running dishwashers, playing a foundational role in the health, safety, and growth of communities. Without efficient infrastructure, leaking pipes or untreated wastewater can pose risks to public health and property.
Key Functions of Sewer Infrastructure
Wastewater Collection and Treatment
Wastewater from properties is safely collected and transported to treatment plants, where it’s treated to eliminate harmful bacteria, chemicals, and other contaminants.
Stormwater Management
Sewer systems help cities manage stormwater by directing excess rainwater away from streets and properties into controlled environments for disposal.
Environmental Protection
When managed correctly, sewer systems protect rivers, lakes, and other natural resources from pollution caused by untreated sewage or chemical spills.
Cost-Effective Solutions for Communities
Investment in modern sewer infrastructure reduces repair costs over time, ensuring smooth residential and municipal operations for years to come.
Breaking Down Sewer Costs and Billing
For many sewer customers, the sewer bill is a recurring expense tied to water usage and wastewater services. Understanding how this bill is calculated—and where the fees go—can empower you to track usage and engage with the billing or payments process more effectively.
What Does Your Sewer Bill Cover?
Sewer bills typically reflect costs associated with maintaining a city’s sewer infrastructure, water treatment, and environmental safety measures.
Usage Fees
These are based on the volume of water used at your property. Residential or municipal sewer systems often scale costs depending on usage tiers.
Maintenance Costs
A portion of your payment helps maintain sewer pipes and treatment facilities within your city or county.
Environmental and Safety Initiatives
Municipal sewer operations often involve collaborative agreements with agencies to fund safety projects and environmental protection programs.
How to Pay Your Sewer Bill
Cities and counties offer multiple ways for customers to make sewer bill payments, ensuring convenience for any lifestyle. These include:
- Online Portals: Pay your bill through secure websites maintained by the city or county offices.
- Mail Payments: Send payments via traditional mail to the specified office address listed in your billing statement.
- Automatic Billing: Set up recurring payments for seamless transactions from your account.
- Customer Service Centers: Visit office locations for in-person payments or assistance.
Remember to update your mailing or email addresses with customer service when moving properties to ensure uninterrupted billing and communication.
Maintaining Sewer Systems to Protect Communities
Properly functioning sewer systems require consistent maintenance and regular inspections. Whether you’re a DIY enthusiast handling clogs or a municipality managing large-scale infrastructure, preventive action can protect both the environment and the financial health of your community.
Tips for Homeowners and DIY Enthusiasts
Use Drain Covers
Install drain covers to catch debris such as food scraps and hair before they enter your sewer connection.
Dispose of Trash Responsibly
Never flush trash or cooking grease down the drain; they can clog pipes over time.
Schedule Routine Maintenance
Engage licensed plumbing professionals to inspect sewer lines and conduct necessary repairs before a costly emergency arises.
