Sump Pump Discharge: Understanding Your Legal Rights And Responsibilities

Sump pumps are used to prevent flooding in homes, particularly in basements. While sump pumps are useful in removing excess water, there are laws in place that govern where the water can be discharged. It is illegal to discharge a sump pump into the street or onto a sidewalk, as this can cause water to flow back into your or your neighbour's home, causing potential water damage. It is also illegal to discharge a sump pump into a sanitary sewer, as the sewer system cannot accommodate the volume of water generated by subsoil drainage systems.

It is illegal to discharge sump pump water into the street

Discharging a sump pump into the street is illegal because the water could potentially flow back into your house or your neighbour's homes. If your house is located at a higher level, the water could flow into the houses of neighbours on the lower end of the street. Even if the street is not sloping towards your home, if the pump is close to the foundation, the water could still find its way back into your home.

Water damage to your home could result in expensive repairs. If the water flows into your neighbours' homes, you may also be held liable for their repair costs. In addition, if the water freezes on the street in colder months, it could pose a hazard to pedestrians and drivers.

Instead of discharging into the street, sump pump water should be directed away from your home. It is legal and advisable to discharge sump pump water into side or rear yards, into drainage ditches, or into city storm sewers with approved connections to street drainage systems.

Sump pump discharge into a county sanitary sewer is prohibited

Another reason for the prohibition is the financial impact on the city and other homeowners. When a sump pump discharges into the sanitary sewer, the city cannot track and bill for the additional usage of the sewer system. This means that the city loses revenue, and other homeowners who are billed based on their water usage end up paying for a service that someone else is using for free.

Furthermore, excessive sump pump discharge into the sanitary sewer can lead to flooding in basements, affecting both the homeowner and their neighbours. To avoid this, it is recommended to install gutters and downspouts to manage water effectively and ensure that it is directed away from the property.

In some cities, it is legal and advisable to discharge sump pump water into yards, street curbs, gutters, or drainage ditches. Some cities also allow direct connections to storm sewer systems. However, it is essential to follow local regulations and ensure that the discharge is directed appropriately to avoid any potential issues.

Sump pump discharge must be directed away from adjacent properties

Sump pumps are systems used to collect and remove water that has accumulated in or under a basement floor, discharging it to the surface area outside the home. The discharge point is typically on the property, away from the foundation, and directed towards the grass, driveway, or storm sewer system.

It is important to ensure that the sump pump discharge is directed away from adjacent properties to avoid potential issues. If the discharge is directed towards neighbouring properties, it can cause problems such as killing the grass and contributing to sanitary sewer backup issues.

To prevent issues with adjacent properties, it is recommended to maintain a safe distance between the sump pump discharge and the property line. A safe distance for sump pump discharge is a minimum of 10 feet away from your home, with 20 feet being ideal. Additionally, it is essential to prevent clogs in the discharge line by periodically flushing the pipe and installing a grated cover to catch debris.

In some cases, sump pump discharge can be directed towards the storm sewer system, but it is important to check local regulations and ensure proper connections to street drainage systems. The City of Madison, WI, for example, allows direct discharge to the storm sewer if it is available within 100 feet of the property.

Sump pump discharge into a storm sewer is usually permitted

Sump pumps are designed to quickly remove water from around your home's foundation, especially during heavy rain. While this water can be discharged into a sewer system, it is important to note that there are separate sewer systems for sanitary waste and stormwater. In most US cities, it is illegal to discharge groundwater from sump pumps into the sanitary sewer system. This is to avoid overwhelming the system with clean water during rainy seasons, potentially causing sewage backups in your home and neighbourhood.

However, sump pump discharge into a storm sewer is typically permitted and even recommended. Storm sewers are designed to handle large volumes of water, making them ideal for sump pump discharge. This method requires professional installation to ensure compliance with local codes and prevent issues. Connecting to the storm sewer system may involve paying the village or city to connect your home. It is important to contact your local municipality to verify the specific regulations and requirements.

Some older homes may have sump pumps connected to storm sewers, while newer homes often discharge into a grassy section of the yard that slopes away from the house. Maintaining the discharge pipe by regularly inspecting it for debris, clogs, or damage is crucial to ensure proper water flow. Improper sump pump connections can lead to legal repercussions, environmental damage, health hazards, and costly fines. Therefore, understanding the risks and alternatives is essential for responsible home maintenance.

It is worth noting that local regulations, such as in North Carolina, may prohibit discharging water in a way that harms neighbouring properties or the municipality. Additionally, during a home inspection, illegal plumbing connections can become a significant issue, potentially impacting the sale of the home. Properly discharging your sump pump can help prevent pollution and protect your local environment.

Sump pump discharge into a septic system is not allowed

Sump pumps are installed in crawl spaces or basements to prevent water leaks and flooding. They are designed to activate automatically once the sump pit accumulates a certain water level. Due to the nature of how sump pumps work, they should not be configured to discharge into a septic system.

Connecting a sump pump to a septic system can lead to flooding. This is because, during wet weather, septic or sewer systems usually struggle to manage normal water flow and discharge from the house. Adding a sump pump discharge can quickly fill up the system and cause flooding. This is especially true during heavy rains when the amount of water being pumped out is typically higher.

Some states consider connecting a sump pump to a septic system to be pollution and have made it illegal. Even if it is legal in your state, it is not advisable to connect a sump pump to a septic tank. This is because limiting the water entering the system improves its performance.

Instead of discharging into a septic system, sump pump discharge should be directed outside of the house, as far away from the foundation as possible. This can be achieved by routing the discharge pipe from the sump pump to a rain garden or dry well. A rain garden is a small depression in your yard designed to hold and soak up rainwater. A dry well is made up of a perforated barrel that collects water and disperses it underground.
