Stormwater, in relation to public works, refers to the water that originates from rainfall or rising waterways and flows over land, roads, rooftops, and other surfaces. As it flows, stormwater picks up pollutants, such as oil, chemicals, sediment, and litter, before eventually entering storm drains or natural water bodies like rivers and streams.

In the context of public works, managing stormwater is an essential aspect of infrastructure planning and development. The Public Works department is responsible for implementing stormwater management strategies to mitigate flooding, reduce pollution, and protect the environment.

Some critical components of stormwater management in public works include:

1. Drainage Systems: Public works departments design and maintain drainage systems, such as storm sewers, gutters, and catch basins, to collect and channel stormwater away from roads and properties.

2. Detention and Retention Facilities: Public works may construct and manage detention ponds, retention basins, or underground storage systems to temporarily store and slowly release stormwater, reducing the risk of flooding and allowing for pollutant removal.

3. Stormwater Quality Improvement Measures: Public works implement measures like constructed wetlands, bio-swales, and sediment basins to capture and treat stormwater runoff, removing pollutants before it enters water bodies.

4. Education and Outreach: Public works plays a crucial role in educating the community about stormwater management practices, encouraging responsible behavior, such as proper disposal of waste, minimizing chemical use, and promoting the use of rain barrels or green infrastructure.

5. Regulatory Compliance: Public works departments collaborate with regulatory agencies to ensure compliance with stormwater regulations, permits, and best management practices.

Overall, stormwater management within public works focuses on preventing water-related issues, improving water quality, and safeguarding the natural environment while promoting sustainable and resilient infrastructure for the community.
