Water Conservation and Pollution Prevention. Water conservation is the main focus of Level Three of the King County Green Schools Program. After each school or school district completes the Level Three Best Practices Guide, recognition is awarded. For a description of the program, visit How it Works. Schools can play a vital role in reducing our region's water consumption and protecting this precious natural resource. Schools use water for a variety of purposes including classroom instruction such as in science labs, and for drinking, cooking and cleaning. Water consumption in schools can be reduced by properly maintaining plumbing fixtures and irrigation systems, investing in faucet aerators and other water-efficient tools, and through simple actions such as regularly checking for leaks and drips. For ideas on how your school or district can decrease its water consumption and teach students about the importance of conserving and protecting water, see the Level Three Best Practices Guide.

Here we’ll tackle the new Phase II Municipal Stormwater Permit, which covers the next most populated areas and affects nearly 100 cities around the state. These cities are legally obligated to try to control water that runs off pavements, roofs and streets in built areas every time it rains. Along the way, that water picks up toxic metals, motor oil, lawn fertilizers, animal droppings, and a cocktail of other pollutants before it washes into local waterways and oceans. The rules governing how cities and other jurisdictions manage this dirty runoff are contained in municipal permits, which were recently updated in Washington State and are about to kick in throughout much of the state.

As you may imagine, there are significant differences between two region’s Phase II permits. Annual Report Questions for Cities, Towns and Counties. Water and Land Resources Division: Annual rates.
