Nyloplast® Water Control Structure

Nyloplast<sup></sup> Water Control Structure

The Nyloplast Water Control Structure is an innovative storm water management basin that provides an effective way to manage water levels in a variety of applications.

Water level management is an important part of any drainage plan. The Nyloplast Water Control Structure combines the superior Nyloplast basin technology with the ability to control level and discharge dynamics and modify them based on outside boundary conditions and current conditions.

This is an economically effective way to improve water quality of our valuable receiving streams, rivers and lakes.

Engineered for Optimal Performance

Proactive water management is important for many reasons. In agricultural applications, it is critical to keep nutrients in the field before they become pollution in a stream. This Water Control Structure allows overflow for heavy rainfall events, but also restricts water movement during normal conditions to maximize residence time for valuable nutrients so they can stay in the crop zone.

In addition to agricultural uses, the structures can be used in a variety of other applications, including general water level management, wetland management, riparian zone control, residential flow control and more.
