Dispose of household products safely. Don’t pour solvents, pesticides, paint thinners, engine oil, or household cleaning products with hazardous chemicals down the drain or into a storm sewer. Take them to a recycling center or hazardous waste collection site. Cooking oils and grease should be collected in a container, covered, and disposed of as solid waste. Fats, oils, and grease collect in the sewer system and are a major cause of blockages and sewage back-ups.
Use fertilizers and pesticides carefully—and only as directed. Try to find safe alternatives to products that can harm water supplies. Be informed. Learn about your local wastewater treatment system as well as water supplies and any possible threats your water supply and environment faces. Know what your community is doing to protect your environment and water supply. Help other citizens be aware of the importance of clean water in your community.
