What is a stormwater pond?
Stormwater Ponds: Purpose and Maintenance
Overview:
Stormwater ponds help prevent flooding and keep our water clean. Taking care of your pond helps protect your neighborhood and keeps it looking nice.
Understanding the Purpose of a Stormwater Pond
Stormwater ponds collect rainwater runoff, which can carry pollution and cause flooding in developed areas. These ponds:
-
Reduce flooding by holding excess rainwater
-
Prevent erosion
-
Help remove pollutants before water reaches streams and lakes
Most developments are required to have a properly working pond for stormwater management.
Types of Stormwater Ponds
-
Detention Pond (Dry Pond): Holds water after rain and drains within about 24 hours
-
Water Quality Pond (Wet Pond): Keeps water year-round and helps clean it naturally. These should drain with in 48 hours.
Pond Inspections
Check your pond monthly and after large storms. Look for:
-
Trash, debris, or sediment buildup
-
Blocked inlets or outlets
-
Erosion on pond slopes
-
Areas that need mowing or new grass
-
Proper drainage
Maintenance Guidelines
All Ponds:
-
Mow grass regularly (keep height at 4–6 inches)
-
Remove trash and debris
-
Repair erosion or damaged structures
-
Remove sediment if pond capacity is reduced
-
Replant grass in bare areas
Water Quality Ponds:
-
Follow your Water Pollution Abatement Plan (WPAP)
-
Clean out sediment and debris from structures
-
Rake sand filter areas to prevent buildup
Why Maintenance Matters
Poorly maintained ponds can lead to:
-
Increased flooding
-
More pollution downstream
-
Bad odors and algae growth
-
Insects and an unattractive appearance
Things to Avoid
-
Do not clean equipment near ponds or storm drains
-
Do not mow grass too short
-
Do not leave grass clippings in the pond
-
Do not use chemicals near the pond that could wash into the water
Important Reminder:
Failure to maintain your pond may result in enforcement actions by the City or the Texas Commission on Environmental Quality.
