What is Stormwater?
Stormwater is pure rainwater plus anything that the rain carries along with it like pollutants, trash and sediment. Unlike sewage, stormwater is not cleaned at a wastewater treatment facility. Whatever enters the storm drain goes directly into local creeks and lakes in our area. Click below to learn more about protecting our water.
Stormwater Management Program (SWMP)
The Stormwater Management Program (SWMP) is a document created by the City detailing actions and activities it will perform in order to reduce the potential for water pollution from stormwater.
The SWMP is a permit requirement from the Texas Commission on Environmental Quality (TCEQ). In order to comply with TCEQ regulations, the City must follow through with the commitments outlined in the plan. Changes to the SWMP can be made to improve effectiveness.

Why is it important to drain your pool correctly?
Pool water contains chemicals such as salt and chlorine. When you drain your pool or spa water into the storm drain, it goes into our creeks and lakes, and these chemicals are harmful to the environment and wildlife.
Follow these steps to comply with Mansfield City Code Chapter 52 when draining or backwashing your swimming pool or spa.
There are two options for draining your pool or spa
Whichever option you chose, remember you must dechlorinate the water before you drain.
How to dechlorinate your pool:
- Allow water to sit in the sun for five to 10 days without adding any chlorine or other chemicals, or use a chemical dechlorinating additive (contact your pool store for options).
- Using a chlorine test kit, verify that your water is dechlorinated. Chlorine levels should be .5 ppm or less, and cyanuric acid should be 20 ppm or less.
Option #1 - Drain pool or spa water to the sanitary sewer system:
- Locate the sanitary sewer cleanout pipe on your property. Sanitary sewer cleanout pipes are typically located somewhere near the front of the house (sometimes hidden in a flower bed), and are made of white PVC pipe.
- Using a hose, connect a siphon or sump pump that pumps no more than 50 gallons per minute. Keep at least a two-inch gap between the hose and the cleanout pipe.
- Pump the water from the pool or spa to the cleanout pipe. Replace the cleanout pipe covers when pumping is complete.
Option #2 - Drain pool or spa water to yard or landscaped areas:
- Allow water to soak into the grassy or landscaped areas of your yard. This will filter out any residual pollutants.
- Drain slowly enough to avoid flooding of your neighbor’s property or any other a property nearby.
- If white filter material starts to flow into the street, move the hose so it only flows onto your yard.
DO NOT drain swimming pool or spa water to your SEPTIC SYSTEM, as it can cause system failure.
