What is the purpose of storm drains?
Storm Drains & Stormwater in Georgetown
Overview:
Storm drains play a critical role in protecting Georgetown, Texas from flooding by quickly moving rainwater off streets and into local waterways. Understanding how stormwater flows and how everyday actions affect it helps keep our creeks, lakes, and drinking water clean.
Purpose of Storm Drains
Storm drains are designed to prevent flooding during heavy rain events. They work by:
• Collecting large volumes of rainwater from streets and surfaces
• Transporting water quickly through underground pipes
• Directing runoff into nearby creeks, rivers, and lakes
However, litter and debris can block these drains, which can:
• Restrict water flow and increase flood risk
• Carry germs and bacteria into local waterways untreated
Proper waste disposal helps keep the system functioning effectively.
Understanding Stormwater
During rainfall, stormwater moves through the environment in a predictable way:
• Water runs off roofs, driveways, and streets
• It enters the system through catch basins and storm drains
• It flows through pipes and channels to local waterways
As it travels, stormwater can pick up pollutants such as:
• Animal waste
• Litter
• Pesticides and fertilizers
• Oil and grease
• Soil and sediment
This runoff is not treated and eventually drains into waterways used for:
• Fishing
• Swimming
• Drinking water sources
Fact:
Georgetown operates a dedicated stormwater system that is completely separate from the wastewater system.
Tips for Cleaner Water
Residents can help protect local waterways by following these practices:
• Properly dispose of household chemicals at hazardous waste collection events
• Store chemicals in tightly sealed containers in cool, dry, well ventilated areas
• Allow pool water to dechlorinate for at least five days before draining onto grass or vegetation
• Never drain pool water into streets or storm drains
• Choose eco friendly alternatives such as oxygen bleach or hydrogen peroxide
• Follow product label instructions when using chemicals
• Apply fertilizers and pesticides sparingly
• Pick up and properly dispose of pet waste
• Recycle paint and used oil and never pour them into storm drains
• Secure trash in covered containers to prevent it from blowing away
The Role of Stormwater Ponds
Neighborhood ponds are important parts of Georgetown’s stormwater system. They provide several benefits:
• Help prevent flooding by storing excess rainwater
• Reduce erosion in nearby waterways
• Improve water quality by filtering pollutants
Common types of ponds include:
• Detention ponds, which temporarily store large volumes of rainwater and release it slowly
• Water quality ponds, which retain water long enough to allow pollutants to settle out
Together, these systems help protect the community and preserve the health of local waterways.
