Stormwater Best Management Practices. The primary method to control stormwater runoff is the use of best management practices (BMPs). Stormwater BMPs are devices, practices, or methods that are used to manage stormwater runoff by controlling peak runoff rate, improving water quality, and managing runoff volume.

The stormwater runoff from highway construction sites typically contains a large amount of fine particles that are difficult to remove using conventional best management practices. Stormwater with high turbidity levels can negatively affect the water quality of receiving waters and natural habitats of rivers, lakes, and streams.

The pH of the stormwater must be in the proper range for the polymers to be effective, which is typically 6.5 to 8.5. The coagulant must be mixed rapidly into the water to ensure proper dispersion. A flocculation step is important to increase the rate of settling, to produce the lowest turbidity, and to keep the dosage rate as low as possible.

Effective stormwater management often occurs by using a holistic system management approach. This approach takes into account the effectiveness of each stormwater practice, the costs of each practice, and resulting overall cost and effectiveness rather than looking at each practice in isolation.
