Have you ever pondered the intricate workings of your sewer system? Well, chances are you haven’t. Perhaps a more compelling question is: Do you grasp the significance of understanding how your sewer operates? The reason is simple: everything is interconnected! A comprehension of sewer systems and their functioning can contribute to better safeguarding our broader environment, encompassing water sources and ecosystems downstream from our flushing activities.

Sewage systems comprise networks of pipes, force mains, and pumps employed in gathering sewage or wastewater from specific locales. Various sources contribute to wastewater or sewage, including communities, educational institutions, and residences.

Sewerage systems are bifurcated into two categories: industrial and domestic sewers, and storm sewers. In certain instances, the system is configured to necessitate a distinct set of network pipes, outfall sewers, and mains for managing both runoff and sewage.

It is advisable to employ a dedicated network of pipes for domestic and industrial sewage, alongside a separate system for storm runoff. The advantage of such a configuration lies in the ability to direct domestic and industrial waste directly to a disposal point or redirect it to a temporary detention basin.

The significance of sewage systems for residences cannot be overstated. Sewage carries pathogens that can spread through the fecal-oral route, implying that if one individual falls ill, they may transmit the infection to others. Nevertheless, sewage treatment serves to separate individuals from their waste, thereby playing a pivotal role in safeguarding public health.

In numerous urban areas and residential dwellings, sewage systems often fall short of expectations, posing health risks for hundreds or thousands of people worldwide. The Go-To Guidebook is designed to assist homeowners in maintaining their sewer systems, providing insights into their functionality and outlining essential steps to ensure proper wastewater treatment.

Why Maintaining Your Sewage System Is Crucial

Ensuring the proper maintenance of your sewage system is not only a matter of cost savings but also a critical step in safeguarding both human health and the environment. Here’s why it’s imperative to uphold your sewer system:

As a homeowner, it is your responsibility to uphold the maintenance of your sewage system. This serves as a means of safeguarding your investment and concurrently protects the public from potential sanitation and health hazards. A well-constructed sewage system ensures the long-term and efficient treatment of wastewater in your residence.

Inadequate design of a sewerage system can result in a multitude of problems. It’s crucial to be aware that replacing a malfunctioning sewer system can incur substantial costs, often reaching thousands of dollars. Moreover, a malfunctioning system has the potential to contaminate underground water sources, which might serve as a drinking water reservoir. The faulty sewage system can also adversely impact the resale value of your home.

To streamline maintenance efforts, it’s advisable to possess an accurate diagram depicting the sewage system’s location. This facilitates maintenance providers in locating and addressing issues promptly.

As a homeowner, it is prudent to establish an annual service contract with the individual or entity responsible for the system installation. Beyond yearly inspections, the system should undergo servicing every 2 to 5 years, contingent on the daily sewage flow and the number of occupants utilizing the system.

When scheduling sewage system servicing, consider the following:

Engage a certified professional for the task.
Avoid completely scrubbing the septic tank; leave a small quantity of sludge to renew bacterial activity.
Opt for springtime maintenance instead of fall, preventing solid waste from leaving the tank during winter months.

Here are four key practices to maintain your septic tank:

Proper care for your drain field
Efficient use of water resources
Refrain from disposing hazardous waste in toilets or sinks
Regularly pump the tank and conduct system inspections.

Categories of Wastewater:

Residential Wastewater: This category comprises water used in households and residential complexes, commonly known as domestic wastewater or sanitary sewage. It encompasses the discharge from daily activities, including bathing, washing, and the disposal of bodily waste.
Industrial Effluent:Industrial wastewater originates from chemical or manufacturing processes and is characterized by contamination. It often contains a diverse range of harmful compounds that can pose risks to both human and animal health.
Stormwater Runoff:Storm sewage pertains to water runoff resulting from atmospheric precipitation, such as rain, drizzle, and snow. It collects in open channels and contributes to the overall sewage system during weather events.

These classifications delineate the diverse sources and compositions of wastewater, underscoring the need for tailored treatment approaches in sewage management systems.

Elements of Sewage Systems

A comprehensive sewage system requires the integration of various crucial components to achieve its objectives. These key elements encompass:

Drains: Subterranean passages beneath urban landscapes designed to guide water into the sewer system.
Connections: An assemblage of elements situated outside structures, establishing the link between their drainage networks and the primary sewage system.
Stormwater Detention Vault: Reservoirs crafted to detain water collected from collectors, averting potential flooding during intense rainfall.
Collectors: Tasked with gathering and conveying water from drains to the principal collectors.
Interceptor Outfalls: These outlets facilitate the conveyance of water from the primary collectors to treatment plants or designated discharge points.

In addition, several secondary components, though not primary in nature, hold significant importance:

Street Gutters: Spaces designed for the collection of rainwater on road surfaces, subsequently guiding it for proper drainage.
Scupper: This component serves to collect rainwater originating from street gutters.
Manholes: Purposeful openings strategically designed to provide easy access to sewage systems, simplifying maintenance procedures.

Types of Sewerage Systems

Sewerage systems come in various categories, each with its distinctive features. The main categories include:

Combined System:A combined system refers to a single network of sewers responsible for handling both stormwater and sanitary sewage.This system consolidates the conveyance of stormwater and domestic sewage into a unified sewer network.

Separate System:A separate system entails distinct sewer networks for industrial sewage and domestic sewage. Additionally, stormwater and surface water follow a separate set of sewers. Industrial and domestic sewage share one sewer system, while stormwater and surface water maintain segregation through a different set of sewers.

Partially Separate System: In a partially separate system, a combination of separate and combined systems is employed. Some stormwater is permitted to enter the sewer lines carrying sewage, while the remaining stormwater follows a dedicated sewer system. This system allows controlled integration of stormwater into sewage pipelines, while the majority of stormwater retains a separate path.

These distinctions in sewerage systems cater to a variety of needs related to stormwater management, industrial waste, and domestic sewage.

 

Separate Sewer System

From an economic perspective, the distinct advantage of a separate system lies in its treatment of a relatively smaller volume of water. This is attributed to the fact that wastewater flows through a separate sewer, resulting in a more cost-effective treatment design.
In contrast to a combined system, a separate system proves to be more cost-effective since only sanitary sewage is directed into enclosed sewers, while non-foul stormwater flows through open drains or gutters.When it comes to sewage disposal needs, the separate system offers a more economical solution.Notably, the separate system exerts no adverse effects on stream pollution.

Combined System

Due to the substantial quantity of sewage, a high velocity is achieved, inducing a self-cleansing effect and obviating the necessity for flushing.The sewage is commonly diluted by rainwater, facilitating an easy and cost-effective wastewater treatment process.This system involves the use of a single set of pipes, simplifying household plumbing.

Partially Separate System

A partially separate system represents an advancement over the separate system, offering an economical solution that accommodates smaller-sized sewers effectively.
By reducing household plumbing requirements, the partially separate system allows sullage from kitchens and baths, along with rainwater from the roof, to be conveyed through the same pipe that carries discharge water from toilets. Water from all other sources is directed through separate drains or sewers.Allowing a modest portion of stormwater into sanitary sewage increases the sewage volume, eliminating the need for flushing.
