Why drainage is important for a safe & healthy home

Drainage is one of the most crucial aspects of home construction and long-term comfortable living. Out of sight and typically out of mind, our drainage systems are much like any other aspect of plumbing, in that they get little consideration until something goes wrong. Even though it can seem like a simple concept, proper drainage is not just about preventing puddles in your yard after a heavy rain. It plays a critical role in protecting your home’s foundation, landscaping, and overall structural integrity.

Why is drainage important?

Drainage is defined by the plumbing infrastructure that helps prevent water accumulation by channelling excess water from a specific area. This process involves installing various components like gutters, downspouts, grading and drainage pipes to redirect water away from vulnerable areas. 

Effective drainage ensures that rainwater and runoff are safely dispersed. By controlling the flow of water and promoting its proper disposal, drainage systems help maintain the integrity of properties, preserve landscapes and protect against costly repairs, making them an essential element of any well-maintained home.

The financial value of drainage

Of course, drainage doesn’t only define the act of diverting unwanted water from your property. As well as saving you the cost of damage, Ddrainage systems can be constructed for rainwater harvesting, which can help households offset their water consumption and decrease demand on public utilities. A harvesting system can help you harness rainwater for non-potable uses like irrigation, toilet flushing and laundry, ultimately reducing your water bills.

Rainwater harvesting systems also contribute to environmental sustainability by conserving freshwater resources and reducing the strain on ecosystems. By capturing rainwater before it runs off into storm drains, these systems help prevent soil erosion, mitigate flooding, and replenish groundwater supplies. 

What happens without a properly working drainage system?

You, your home and the environment can all be impacted by the absence of a working drainage system. Stormwater, for example, can pick up rubbish, oil, sediment, animal droppings, chemicals, plant nutrients and other contaminants during excessive rain. These can collect on your property, affecting your plants, your health, and the surrounding ecosystem. Working drainage can carry these contaminants away, preventing them from causing any environmental or health-based problems.

Here are some other potential outcomes that show why drainage is important.


A faulty drainage system can prevent water from being diverted safely away from your home. Blockages or cracks and cause water to build up in the surrounding area, resulting in oversaturation of the soil. With nowhere to go, the buildup can prevent the oversaturated soil from recovering, causing flooding to occur more quickly during heavy rain or excessive water use.

This can lead to…

Soil erosion and subsidence

When soil is no longer dry and compact, it has a greater tendency to shift, or react, underground. Poor drainage can cause water to impact the integrity of the soil in our gardens, underneath our roads and pathways, or around the foundations of our homes. If the soil applying support against our structures washes away, then the structure itself can be at risk.

This can lead to…

Property damage

If your home’s foundations aren’t sitting within stable soil conditions, they may be at risk of sinking, shifting or failing. This can lead to cracked walls and , uneven windows, and  door frames and uneven floors that, in extreme cases, can collapse and give way.
