Common Mistakes When Installing a Retention Pond

Retention ponds help manage stormwater runoff and prevent flooding. However, their effectiveness is highly dependent on correct installation and maintenance. Unfortunately, many people run into common pitfalls during the installation process. You can avoid issues by reviewing these common mistakes when installing a retention pond. 

Overlooking Local Climate and Soil Conditions

Too often, retention ponds fail because contractors design them without thoroughly analyzing the local climate, rainfall patterns, and soil type. This can lead to a system that neither retains water appropriately during wet periods nor maintains its structure during dry spells.

It’s best to conduct a thorough site assessment, including a detailed hydrology study and soil analysis, to determine the pond’s design and ensure it aligns with the landscape.

Failing To Properly Size and Locate the Pond

Misjudging size and location is a common mistake when installing a retention pond. An inadequately sized or poorly located pond will not prevent flooding and may become a liability rather than an asset. Issues such as shoreline erosion, turf deterioration, and blockages can occur. 

Calculating the pond’s dimensions and strategically placing them is essential. Furthermore, consider future development plans and climate change projections to ensure the system can handle increases in runoff.

Inadequate Construction Techniques

Another frequent error is cutting corners during construction, especially in the compaction of the pond’s embankments. If you compact insufficiently, heavy rains might erode the soil, undermining the pond’s stability and providing a direct path to failure.

Always opt for high-quality materials and the best construction techniques; never cut corners on the compaction process. Additionally, installing retention pond liners offers additional protection against seepage and erosion, safeguarding the pond’s structural integrity over time.

Disregarding Regulatory Compliance

Non-compliance with local regulations and environmental requirements is more than just an oversight—it can lead to hefty fines and even legal action. It’s critical to understand and adhere to the laws that govern retention pond construction and maintenance in your area. Your local environmental law expert can help ensure your pond meets legal standards.

Neglecting Regular Pond Maintenance

A retention pond is not a “build it and forget it” project. Neglecting routine inspections and maintenance can induce overgrowth of vegetation, clogging, and a decrease in capacity, severely limiting the pond’s functionality. Establish a maintenance schedule with routine cleanups to prevent blockages and maintain the system’s storage capacity.
