What You Should Know About Drainage Systems

Drainage Systems

Understanding your home’s drainage system is essential. By securely transporting stormwater away from houses to creeks and rivers and discharging your household wastewater into the main sewage system, the drainage system helps to reduce the danger of floods. Drainage systems that are properly working and well-maintained are critical since inadequate drainage can lead to a variety of issues.

It is critical to consider your drainage system while constructing and building your home. To guarantee quality and durability, it must be built in compliance with the Plumbing Code of Australia (PCA).

What is a home drainage system made up of?

A drainage system is a huge network of pipes that begins with residential gutters, downpipes, and pipelines, all of which are the homeowners’ responsibility. It then links to the drainage system that runs across towns and cities, ensuring that no homes are flooded.

Residential drainage systems aid in the direct conveyance of stormwater and domestic water wastes to the sewer. A home with a poor drainage system may be terrible for both you and your property.

You must make certain that your home’s drainage system is in good operating order. Improper and inappropriate drainage installation can result in leaks, a damaged roof, a weakened foundation, the spread of mould and mildew, and even flooding.

The following are the elements of a fully operating home drainage system:

Stormwater Drainage System

Stormwater may cause major difficulties if it is not correctly routed to your neighbourhood’s main drainage system. Stormwater drainage should be included in your home’s drainage system. You may also utilise the water collected by a rainwater collecting system to clean or water your lawn and garden. You might also divert all stormwater to your city’s main sewer systems.

Gutter Protection Systems

Your gutter system is crucial—not just for your roof but also for the rest of your home. It serves as your home’s first line of defence against the assault of rainwater and is a crucial part of your drainage system.

Your gutter system has a single purpose: To drain rainfall away from your home and its surroundings, including your grass and driveway. Stormwater may wreak havoc on the things you’ve worked so hard to achieve. It safeguards your home’s foundation, grass, and landscaping, avoids soil erosion, safeguards concrete walks and roads, and keeps your basement from flooding. Gutters also assist to maintain your home’s paintwork and prevent mould and mildew from growing. Adding a gutter guard to your drainage system can help reduce cleaning and backups.

Stormwater has to go somewhere if you don’t have gutters. It can spread throughout your house since there is no structure to stop it. It may wreak havoc on your electrical wires, ceiling, and even walls. Moisture is one of your home’s worst enemies, causing costly and irreversible damage.

Stormwater running down your roof may ruin your driveway, and it can also harm your well-kept lawn and landscaping.


The downpipes take the rainfall from the gutters and channel it into the ground. The water can then run straight to your city’s main subsurface drainage system or to your stormwater or rainfall collection system. The purpose of downpipes, like your gutters, is to move rainfall away from your home and into your municipality’s main stormwater system.

Your downpipes’ specs may be affected by the quantity of rain in your area. Brackets, joiners, and offsets are all included with your downpipes. They come in a variety of sizes to suit your needs.

Drainage System for Sewers

Household water wastes should be sent to the city’s main sewage line as quickly as possible. It can cause irreparable harm to your house and pose major health concerns to you and your family if waste is not properly disposed of.

The sewage drainage system in your house is made up of subterranean pipes that transport water waste from your laundry, bathroom, kitchen, sinks, and other plumbing fixtures. These are responsible for transporting sewage from your house to the main sewage system. After that, the treatment facilities can either recycle the water or discharge it into a nearby stream or river.

The following components must be included in your home’s sewage drainage system:

P-Traps: P-traps can be found underneath sinks, bathtubs, and other plumbing fixtures. A P-trap is a curved segment of pipe that resembles the letter P, thus the name. It collects standing water, preventing sewage gases from rising from your sewer system and filling your house with a foul odour.

Traps for Toilets: The toilet trap is similar to a P-trap in function. It’s a curved drain that collects standing water and prevents sewage gases from ascending into the atmosphere.

Washing machine pipes: Your washing machine is linked to these pipes. Your washing machine’s drain tube empties into an open standpipe, which leads to a branch drain into your home’s main drain.

Drain Lines: These pipes link the plumbing fixtures in your house to the main drain lines. Drain lines are generally buried in your ceiling, walls, and floor, out of sight.

Soil Stacks: Soil stacks, also known as main drain stacks, are large-diameter vertical pipelines. Your sewer system is vented through the soil stack vent, which is positioned towards the top of the standing dirt stack. The dirt stack vent stretches upward and escapes into the outside air on your roof. This equalizes the air pressure in your sewage drainage system.

Drainage Main Line: This pipe links your home’s sewer system to the main sewer system of your municipality. This normally goes beneath your home’s foundation slab.\
