Benefits of disconnecting rainwater drainage

In the Netherlands, where rain is a frequent visitor, disconnecting rainwater from sewage systems—known as rainwater infiltration—offers a sustainable solution with numerous benefits, including preventing sewage overflows and conserving groundwater. With the availability of subsidies to support this eco-friendly initiative, ensuring proper implementation through tailored methods and inspections becomes crucial for homeowners looking to optimize their property's rainwater management system.

In the Netherlands, we experience rain all too often. Rainwater can be put to good use on your own property, so it's a good idea to choose to disconnect it. This is also called rainwater infiltration. A special subsidy is available for this, which can amount to €10 or more per square meter. It's important that rainwater disconnection is done correctly. You'll experience many significant benefits. A building inspection can determine whether the disconnection has been arranged correctly.

Disconnecting rainwater drainage in different ways

Disconnecting rainwater sounds very standard, but it certainly isn't. The disconnection method must be tailored to both the terrain and the soil type. Based on this, the correct method must be selected, after which the rainwater drainage system for the property in question must be determined. Disconnecting rainwater can be accomplished with drainage hoses, but infiltration crates or sumps can also be used.

Are you planning to buy a home where all of this has already been done? Then it's important to ensure everything is properly in place. Do you want to do it yourself? Then it's wise to have the necessary inspections carried out first. This way, you can be sure the best possible method is being used. A rainwater drain is the polite word for a rain pipe.

What are the benefits of disconnecting rainwater drainage?

When rainwater is disconnected, the rainwater from the paving and roof surface is disconnected from the combined sewer system. In practice, this means that the rainwater that falls on your roof and paving is not discharged to a sewage treatment plant. Instead, it is discharged into the groundwater. A significant advantage of this is that it can limit water depletion. It also prevents overflows at the sewage treatment plants. This offers significant benefits, and that's precisely why many municipalities offer special subsidies for people who want to disconnect rainwater.

How exactly is the disconnection subsidy arranged?

The subsidy you may be eligible for if you want to disconnect rainwater, also known as the disconnection subsidy, is not regulated uniformly everywhere. Because disconnecting prevents overflows from sewage treatment plants, many water boards and municipalities offer this subsidy. However, the amount of this subsidy varies. In most cases, the subsidy is calculated based on the size of the disconnected roof area, calculated in square meters. Often, the subsidy also covers the purchase of a rain barrel. If you plan to disconnect rainwater, it is advisable to inquire about the current subsidy in your municipality.

Construction inspection of existing disconnection

Disconnecting rainwater can be very useful and offers significant advantages. However, it can also have significant disadvantages if disconnected incorrectly or using the correct method. A building inspection with a comprehensive building report is definitely recommended if you want to be sure everything is in order. Homekeur is ready to assist you.
