4. Manage the stormwater system to protect properties from flooding, ensure that
stormwater entering our creeks and water ways is free of pollutants, and reduce health
risks through our Mosquito Management Program.

3.3 - Mitigate stormwater runoff and flooding risks

Stormwater management programs reduce the risk
of flooding, prevent erosion, and protect water
quality. Development within the City’s floodplains
and floodways is managed by Public Works in
accordance with federal and state laws and
regulations. Engineering administers the Municipal
Separate Service Stormwater System (MS4) permit
and ensures compliance with all regulations
governing clean water and stormwater runoff.
Environmental compliance efforts include the
citywide Integrated Mosquito Management Program
to mitigate public health risks. Regular inspections of
inlets and outfalls reduce the likelihood of hazardous
driving conditions during rain events. The
maintenance and inspection of storm drainage
facilities also reduces the negative impact of the
quantity of rainwater on surrounding properties,
roadway integrity, and stormwater infrastructure.
Monitoring the quality of our runoff for pollutants
protects local water sources in addition to animal and
human life.

5. Guarantee a safe, reliable and adequate water supply is provided to residents and
visitors of Colleyville.

3.2 - Ensure regular replacement of water and
wastewater facilities

The City of Colleyville purchases treated water
from the Trinity River Authority. Water
Distribution then manages this vital resource
around the clock by maintaining three elevated
storage towers, one ground storage tank, a
pump station, and 200+ miles of water mains.
Routine maintenance of these assets includes
flushing dead-end water mains, regularly
replacing meters, and exercising valves throughout the network. Water is routinely
sampled from various sites throughout the city and tested for chlorine residual and
