    The impact of heavy rainfall on drainage systems

    The impact of heavy rainfall on drainage systems: How to prepare for storm season

    | 27 June 2025

    Heavy rainfall can wreak havoc on drainage systems and septic tanks, leading to flooding, overflows, and system failures if not properly maintained. As storm season approaches, it’s crucial to ensure your drainage and septic systems are in optimal condition to handle intense downpours and avoid costly damage to your property.

    In this article, we’ll explore how intense rainfall can impact drainage systems and septic tanks, and why it’s essential to carry out proper maintenance before the storm season to prevent overflows, blockages, and leakage.

    1. How intense rainfall affects drainage systems and septic tanks

    When heavy rains occur, the volume of water can overwhelm both stormwater drainage systems and septic systems, especially if they are not functioning properly. Here’s how intense rainfall can affect these systems:

    1.1 Impact on stormwater drainage systems

    Stormwater drainage systems are designed to channel rainwater away from streets and properties to prevent flooding. However, when these systems are clogged or poorly maintained, they can become blocked or ineffective during heavy rainfall.

    • Blockages from debris: Leaves, branches, trash, and dirt can accumulate in storm drains, obstructing the flow of water and causing backups. When the water has nowhere to go, it can flood streets and cause water to pool in yards and basements.
    • Increased water volume: In areas where the drainage infrastructure is not designed to handle large volumes of rain, the system can become overloaded, leading to localized flooding. This can damage property, infrastructure, and even pose safety hazards.

    1.2 Impact on septic systems

    Septic systems are designed to treat and dispose of wastewater from homes or businesses. However, when heavy rains occur, these systems can be impacted in several ways:

    • Saturation of the drain field: Excessive rainfall can cause the drain field (the area where treated wastewater is absorbed into the ground) to become saturated. When the ground is overly saturated, the septic system has nowhere to send the treated wastewater, leading to potential backups and leakage.
    • Flooded septic tanks: In areas with poor drainage or high water tables, the septic tank itself can become flooded, disrupting the normal treatment process and potentially allowing untreated waste to leak into the environment.

    2. Why maintenance is essential before storm season

    Proper maintenance before the storm season is critical to ensuring that your drainage and septic systems are functioning optimally during intense rainfall. Here’s why it’s essential to carry out maintenance ahead of time:

    2.1 Prevent blockages in storm drains

    • Clearing debris: Before the rainy season begins, inspect and clean your storm drains to remove leaves, twigs, dirt, and other debris. This will ensure that water flows freely and efficiently through the drainage system, reducing the risk of flooding.
    • Installing protective covers: Consider installing mesh screens or grates over storm drains to catch larger debris before it can clog the system.

    2.2 Inspect and clean septic tanks

    Septic systems need to be in good condition to properly handle increased water flow during heavy rains. Failing to clean or maintain your septic system can result in overflows or backups, which can cause damage to your property and lead to costly repairs.

    • Pump the tank: Septic tanks should be pumped every 3-5 years, but during periods of heavy rain, the tank may fill up faster. It’s essential to have the tank inspected and pumped before the storm season to prevent overflows and ensure the system works effectively.
    • Check the drain field: Inspect the septic drain field to ensure it’s not waterlogged. If the ground is saturated, the wastewater can’t be properly absorbed, which can lead to backups and system failure. If the area around the drain field is soggy or has standing water, you may need to address drainage issues before the rain hits.

    2.3 Ensure proper maintenance of the entire drainage system

    • Check for leaks or cracks: Inspect the entire drainage system for any visible cracks or leaks that could allow water to escape and lead to flooding. If you notice any issues, get them repaired before the storm season begins.
    • Evaluate capacity: If your drainage system is older or has a history of flooding, it may not have the capacity to handle the volume of water from intense storms. Upgrading or expanding your system before the season can prevent costly damage later.

    3. How professional services can help

    While homeowners can perform basic maintenance tasks like clearing debris and inspecting the system, it’s often best to hire professional cleaning and maintenance services for a thorough inspection and cleaning of storm drains and septic tanks. Here’s how professional services can ensure your systems are ready for storm season:

    3.1 Professional storm drain cleaning

    • Complete cleaning: Professionals have the tools and equipment to perform a complete cleaning of your storm drains, including high-pressure water jets, vacuum trucks, and specialized tools that remove tough debris and sediment.
    • Inspection and repairs: A professional cleaning service will not only clean the drains but also inspect the system for any damage or areas that need repair. They can catch small issues before they turn into major problems during the rainy season.

    3.2 Expert septic system maintenance

    • Tank pumping: Septic service professionals will pump your septic tank, ensuring it’s emptied and free of sludge buildup, so it can handle the increased water flow during heavy rains.
    • Drain field inspection: Professionals can evaluate your septic drain field and suggest any necessary maintenance to prevent flooding or system failure.

    4. Conclusion: Preparing your systems for storm season

    Intense rainfall can have a significant impact on your storm drains and septic systems, leading to flooding, backups, and environmental contamination if left unchecked. Regular maintenance before storm season is essential to ensure your systems are ready to handle the increased water volume.

    By clearing debris from storm drains, pumping septic tanks, and inspecting the entire drainage system, you can reduce the risk of system failures and protect your property from the damaging effects of flooding.
