1. Where should I drain the water from my pool?

• Into your landscape for irrigation. Pools may be discharged onto your property if the water does not run off into streets or cause stagnant water.
• Into the sanitary sewer system via your home's sewer clean-out. The sewer clean-out is usually a threaded cap about three to four inches in diameter.
• After approval by the Watershed Protection Department, into the storm drain system. Watershed Protection can be reached at 940-349-7153 or 940-349-7141 or send an email to the Watershed Protection Department.

To obtain permission, pool water will have to meet the following criteria:

• Discontinue use of pool chemicals at least three days prior to discharge
• Dechlorinate water to non-detectable level of chlorine (less than 0.1 milligrams per Liter)
• Clean any vegetation and debris from pool
• Monitor discharge rate to prevent erosion
• Freshwater pool water only (saltwater pools cannot be discharged to the storm drain)

2. Where can I discharge pool filter backwash water?

Swimming pool filter backwash should be discharged to the sanitary sewer. Though low in volume, it has a higher concentration of contaminants compared to pool water.

Denton City Code of Ordinances Chapter 26-189 prohibits discharge of pollutants to storm sewer or natural outlet except where suitable treatment has been provided or where a Federal National Pollution Discharge Elimination Systems (NPDES) permit is issued. Fines for violating section 26-189 of the City Code could equal up to $2,000 per violation, per day.
