How to Reach Us
When there is enough rain to flow, we call this "Stormwater". When stormwater runs off from our homes, yards, driveways, and roads; it is called "Stormwater Runoff". Areas that are exposed to rain have a potential to contribute to water pollution.
Stormwater runoff has become a leading cause of water pollution in the US. Heavy metals, nutrients, pesticides and other pollutants are carried into nearby streams, lakes, canals, and rivers by stormwater runoff.

Nutrient pollution, especially from nitrogen and phosphorus, has consistently ranked as one of the top causes of degradation in some U.S. waters for more than a decade.
Excess nitrogen and phosphorus lead to significant water quality problems including harmful algaeblooms, hypoxia and declines in wildlife and wildlife habitat.
Here are some things that contribute to nitrogen and phosphorus pollution:
- Overusing fertilizer (both residential and agricultural usage)
- Fertilizer that is able to make it into nearby waterways via impervious areas.
- Overflow from septic systems
- Rainfall flowing over land picks up animal waste and deposits it in water bodies
- Rainfall flowing over urban and suburban areas where stormwater management is not required (e.g., parking lots, lawns, rooftops, roads)
- Your actions can make a difference! Here are some best practices that will help keep our waters clean.
- Test your turf. Throwing fertilizer on your lawn may be like throwing money down the drain. For example, if your lawn has a problem with the pH balance, pest invasion, or other deficiency then fertilizer will not help and the money, time, and effort will be wasted.
- Keep fertilizer at least 15 feet away from any waterbody.
- If fertilizer is spilled on sidewalk, driveway, or other impervious surface, sweep it up as soon as possible before any rain washes into nearby waterways.
- Calibrate your spreader and make sure to keep a deflector functional to minimize spreading fertilizer into unwanted areas.
- Do not bag or remove the grass clippings from your lawn; clippings can provide up to 50% of the nitrogen your grass needs.
- When mowing your lawn, set the mower deck height for the variety of grass that you have, for instance St. Augusting grass should be mowed at 3.5 to 4" height after cutting.
- Watch the weather and do not apply if we are expecting rain events that may just wash the product right down the drain and into a nearby waterbody.
- Skip the Phosphorus. Florida soils are already rich in phosphorus. Use it only if your soil sample indicates that it is needed.
- Use an iron supplement to green up your lawn during the summer; many times that is all that is needed to make the grass nice and green again.
- The Right Plant in The Right Place. Pick plants that are suitable to your area and annual rainfall.
- Be Floridian. Visit Florida Yards And Neighbors for more information on Florida landscape BMPs.

Decisions you make about your garden can affect the water quality of nearby rivers and streams
- Use fertilizers sparingly and sweep up driveways, sidewalks and gutters
- Plant ground cover in bare spots in your yard
- Never dump anything down storm drains or in streams
- Take your car to the car wash instead of washing it in the driveway
- Pick up after your pet
NPDES is a National System that has its origins in the Clean Water Act. The Environmental Protection Agency has givin most States the authority to administer the program through the use of Generic Permits.
The City of Deltona has one such permit: the Municipal Seperate Storm Sewer System or, MS4 Generic Permit.
This is just what is sounds like: our Storm Sewer is seperate from our sanitary sewer. This means that anything dumped into a storm drain does not get treated and may discharge directly into nearby lakes, streams, or other surface waters, endangering the various species which may call it home.
There are 6 Control Measures to our program:
- Public Education and Outreach as to Stormwater Impacts
- Public Involvement/Participation
- Illicit Discharge Detection and Elimination
- Construction Site Stormwater Runoff Control
- Post-Construction Stormwater Management in New Development and Redevelopment
- Pollution Prevention/Good Housekeeping for Municipal Operations
Deltona then developed Best Management Practices (BMPs) and Measureable Goals to assist in the implementation of these Control Measures.
For more information or volunteer opportunities please contact the City of Deltona NPDES Inspector's Office at (386) 878-8962.
Green Industries-Best Management Practices (GI-BMP) program teaches environmentally safe landscaping practices that help conserve and protect Florida's ground and surface waters.
