Types of Drainage Systems: What You Need to Know

Your drainage system is a critical yet often-neglected building component. When it comes to blocked sewer pipes or blocked pipes in general, a properly working drainage system may be the difference between a simple plumbing repair and a major overhaul.

Weather is a big factor when it comes to drainage system upgrades. Rapid changes in weather conditions often requires the installation of more secure and robust drainage systems. Heavy rains, for example, can overwhelm the system and cause blocked pipes. 

Proper maintenance of drains and understanding the types of drainage systems is important. Blocked drains can be prevented by keeping the drains and drainage system in good working order. Sydney Plumbers have been upgrading their drainage systems with high-quality products developed to withstand extreme weather conditions.

Weather-proof your drainage system by getting an upgrade. Sydney Plumbing has created a new sealing technology that creates an airlock seal around the drainage system which greatly increases its effectiveness by preventing blocked sewer pipes or blocked pipes due to bad weather. This is perfect for homeowners who are concerned about their existing drainage system’s ability to cope with bad weather.

Common Types of Drainage Systems

Drainage is a key component of the plumbing system that should reduce the impact of flooding. A plumbing system  has a complex network of underground pipes, surface channels, and other infrastructures to help reduce flash-flooding incidents that happen when portions of this infrastructure become blocked pipes. The plumbing system is designed to protect the property from water damage caused by rain, snowmelt, groundwater seepage, or surface runoff.

The three main types of drainage systems:
Catchment Area

The catchment area takes care of collecting excess water from the roof, exterior surface, or other areas that are exposed to rainfall or snowmelt. This usually includes gutters and downspouts which direct the collected water into a gutter system, where it’s stored until it can be released through the inlets.


The inlets take care of releasing the excess water when the flow exceeds capacity. Inlet openings direct the water to a drainage system where water can either be discharged through drainage system outlets or closed depending on the system design or structure.

Main Drain

The main drain is the large pipe that takes water collected by the inlets and transfers it to the subsurface drainage system such as storm drain and creek. This is where larger debris like sticks, leaves, broken branches, etc. are filtered out of the flow before they can obstruct the drainage pipes.

Different Types of Drainage Upgrade Options

There are several surface drainage upgrade options on offer, depending on the needs of the property.

Some of the most common upgrade options include:

Ditched and Graded System

This system discharges water to either a nearby creek or gutter located outside the property. It is usually just found in rural areas as it uses natural waterways as a means to evacuate excess water from the property.  While this method is used more often than other systems due to its simplicity, it can have problems with clogging depending on the type of soil it is placed in. This system is best for properties that are located in areas with gentle slopes and soft soil.

Swales and Basins

This system collects rainwater and stormwater runoff. The water is then slowly released from the swale or basin over time which allows it to be absorbed into the ground. This system is beneficial as it helps to recharge groundwater and prevent soil erosion. This system can be found in suburbs where regulations prohibit the construction of storm sewers. It is also versatile, as it can be used in both rural and urban areas.
