Definition: Dry Well

A dry well is a gardening technique used to assist with waterlogged lawns. It is a structure designed to collect and disperse excess water from the surface, preventing waterlogging and promoting proper drainage.

How Does a Dry Well Work?

A dry well consists of a large hole or pit dug into the ground, typically lined with a permeable material such as gravel or crushed stone. This allows water to infiltrate into the surrounding soil gradually. The size and depth of the dry well depend on the severity of the waterlogging issue and the amount of excess water that needs to be drained.

When a lawn becomes waterlogged, the excess water can suffocate the roots of plants, leading to poor growth and even death. By installing a dry well, the excess water is redirected away from the lawn’s surface and into the well. The well acts as a reservoir, temporarily storing the water until it can slowly percolate into the surrounding soil.

The dry well is typically connected to a network of perforated pipes or channels that collect the water from the surface and direct it into the well. These pipes or channels are buried underground to ensure efficient water flow and prevent any obstructions.

Benefits of Using a Dry Well

Using a dry well in a waterlogged lawn offers several benefits:

• Improved Drainage: The primary benefit of a dry well is improved drainage. It helps prevent waterlogging by collecting and dispersing excess water, allowing the soil to dry out more effectively.
• Prevents Soil Erosion: Waterlogged lawns are prone to soil erosion, which can wash away valuable topsoil and damage plant roots. A dry well helps mitigate this issue by redirecting excess water away from the surface, reducing the risk of erosion.
• Promotes Healthy Plant Growth: By preventing waterlogging, a dry well promotes healthier plant growth. It ensures that the roots receive adequate oxygen and nutrients, preventing root rot and other water-related diseases.
• Reduces Standing Water: Standing water not only damages plants but also creates a breeding ground for mosquitoes and other pests. A dry well helps eliminate standing water, creating a more pleasant and pest-free environment.
