Protecting Tulsa's Water Quality

Sometimes, people pollute our waterways without even knowing it. When it comes to our urban streams, the more you know, the cleaner the flow.

Tulsa has two types of sewers: a sanitary sewer that carries wastewater to a treatment plant and a storm sewer that carries rain and other runoff directly into our streams. Contaminated runoff, called nonpoint source pollution, is a major cause of pollution in Tulsa's waterways. We can reduce the pollution by keeping waste such as litter, lawn care chemicals, and other waste out of our storm sewers.

Fertilizer Use Recommendations

How to Reduce Fertilizer Use

Caring for your lawn properly can both enhance its appearance and contribute to its environmental benefits. Healthy grass provides feeding ground for birds, who find it a rich source of insects, worms and other foods. Thick grass prevents soil erosion, filters contaminants from rainwater, and absorbs many types of airborne pollutants. Grass also is highly efficient at converting carbon dioxide to oxygen, a process that helps clean the air.

Proper Disposal

For More Information
The Master Gardener Hotline, (918) 746-3701, provides information on safer alternatives to fertilizers as well as types and amounts of fertilizers to use on your lawn.

Since foreign substances can pollute our waterways and cause flooding, you should never pour products down a drain, sewer or manhole. It also is a violation of City ordinance. Do your part to keep the drainage system clean. If you spot a blocked drain or suspect illegal dumping of products in the drainage system, call (918) 596-2100, and an inspector will investigate.
