Sewage System Simply - What You Need to Know

You probably never thought about sewage systems until you encountered a problem - and that's natural. Who thinks about pipes until strange bathroom noises start bothering you? Let me explain everything you should know about your home's sewage system.

How Does a Sewage System Work? 

Imagine a network of pipes underneath your house where all the water you use daily flows - from bathrooms, kitchens, and washing machines. You then face a choice: connect to the city's central sewage system or, if access is unavailable, install your own biological treatment plant.

Concrete Pit vs. Biological Treatment Plant: Which is Better? 

Let's compare both options:

Concrete Pit:

  • Leaves unpleasant odors
  •  Requires frequent sewage pumping, which means additional costs 
  • Has low filtration - only up to 30% 
  • Pollutes water and soil

Biological Treatment Plant:

  • Filters sewage water by 98% 
  • Can be installed in one day 
  • Comes with a 10-year guarantee and 70-year operational lifespan 
  • Operates silently without odors 
  • Does not require sewage truck services

Ventilation Pipes - Why Are They So Important?

Think of the sewage system as "breathing". This is why ventilation pipes that extend to the roof are crucial. If these pipes are clogged (for example, by leaves), the system "suffocates" and can introduce unpleasant odors into your home or, in worst cases, even harmful gases like methane

How to Maintain the System? Simple Rules to Avoid Many Problems:

  • Do not flush wet wipes, cotton, or other items into the toilet
  • Do not pour grease or oil into the sink
  • Install special strainers in sinks to catch hair and food residues

Exterior Network Installation Advice

Properly setting up a sewage system's exterior network is complex but important. Here are some recommendations:

  • Installation Depth:The minimum pipe burial depth is 30 centimeters. However, it's not recommended to bury too deeply (maximum 1 meter).
  • Trench Setup: The trench should not be too deep to avoid the need for re-filling. Pipes should be laid with a 1-3% slope, meaning a height difference of 1-3 cm per meter.
  • Coverage: Pipes must be covered with sand and well-compacted with water, otherwise pipes might settle.

Additional Important Recommendations:

  • For Long Routes: It's advisable to create inspection wells to facilitate future pipe cleaning and inspection.
  • Pipe Connections: If you need to connect multiple pipes in the yard, do this in a collector well, not with a pipe junction, to avoid clogging risks.
  • Pipe Selection: For private homes, 110 mm diameter pipes are completely sufficient (150 or 200 mm are unnecessary). Choose pipes that can withstand mechanical impact.
  • Bends: Avoid 90-degree angular bends as they clog easily. Instead, use two 45-degree angular transitions.
  • Storm Drains: Categorically do not connect storm drains to the sewage network, as leaves can clog the system.

Interior Network Setup Advice:

  • Traps and Siphons: Definitely install high-quality traps with wet and dry functions to protect against unpleasant home odors.
  • Network Configuration: The sewage system should be collected inside the building with only one outlet pipe outside.
  • Additional Advice: Use ventilation pipes for correct system functioning.

Following these recommendations will help you set up a reliable and effective sewage system. It's time to forget about rudimentary sewage pits. Beyond discomfort, unpleasant procedures, and financial costs, they harm the environment and pose a health risk to those around you.
