Where Does the Waste Pipe Go for a Washing Machine?
Are you wondering where the waste pipe for your washing machine should go? Understanding the basics of waste disposal can help ensure your home is environmentally friendly and follows local regulations.
Standard Drainage Systems
Your washing machine typically connects to one of two types of drainage systems: a sewerage drain or a septic system.
Waste Water Outlet in Houses
In the UK, your washing machine’s drain most commonly connects to the house’s waste water outlet. This outlet is distinct from the sewerage drain. Waste water typically goes to a soak away deep in the ground, whereas sewerage is treated before disposal.
Community Drainage Systems
The waste water from your house usually goes directly into the building drainage system. In many cases, this is located in the kitchen, but it can be situated anywhere in the house. The drainage system ultimately connects to the main drain of the community wastewater system, which can be treated at a local plant before being released into the environment.
Historical Context
It’s worth noting that in the South, through the 1980s, if you had a septic system, your washing machine often had its own drain field or porous tank to prevent overloading the septic system. This system was designed to manage grey water and black water separately to ensure the sewage system was not overloaded with water from multiple sources.
What is a Sewer?
When discussing waste water disposal, sewer is often a term that trips people up. A common misunderstanding is the distinction between a storm sewer and a sanitary sewer. A storm sewer is a system of drainage pipes, gutters, and ditches that collect surface runoff. The grate on the side of the road usually directs rainwater to these sewers.
Storm Sewer
The storm sewer system collects surface runoff and untreated water from the streets and often discharges it into local creeks or ditches. The “Flows to the Ocean” sign on the grate is a reminder not to pour any chemicals into the storm drain as they can harm local ecosystems.
Sanitary Sewer
In contrast, the sanitary sewer system handles black water (waste from toilets, showers, sinks, and washing machines). This water is often treated at a sewage treatment plant, where native or enhanced bacteria break down the waste. Unlike grey water, black water is biologically toxic and requires treatment to protect the environment.
Conclusion
Understanding the different types of water systems and their functions can help ensure you are disposing of waste water properly and minimizing your environmental impact. Whether your home is connected to a main drainage system or a septic system, it’s important to know what the laws and regulations are in your area to maintain a healthy and sustainable living environment.
