Maintain

Channels - Also know as drainage channels or ditches and are commonly found throughout neighborhoods and commonly made of earthen material or concrete.

These assets convey storm water from neighborhoods and developed areas to the nearest creek or river.

Stormwater crews maintain approximately 230 miles of channels that convey stormwater. Stormwater Management provides routine and major maintenance to engineered drainage channels that are located within a City dedicated drainage easement.

Routine work consists of the following...

CHANNEL

Channel Maintenance

• Removing sediments
  and debris accumulation that could impede the flow of water.

Channel Restoration

• Re-stabilizing side slopes of engineered channels.

CONCRETE

Concrete Structures and pipes must be maintained and working at optimal levels, allowing drainage system to operate at maximum capacity as designed.

• Construct and repair concrete structures such as headwalls, concrete flumes, concrete lined channels and curb Inlets.
• Investigating and repair failed sections of pipe which could lead to
  cave-ins.

MOWING

Vegetation in drainage easements must be maintained to a desired condition in order to allow the open channel system to operate at designed conditions.

• Regular mowing provides the channel system with protection from flooding, erosion, and will help to promote desirable vegetation.
• Proper mowing maintenance will reduce the chance of clogging drainage structures and reduces potential of mosquito breeding habitats.

Pipes - Commonly referred to as culvert pipes or drainage pipes and are a network of underground pipes used to convey runoff of our city streets.

Pipe Inspection
With approximately 1000 miles of storm drain pipe in the city of Fort Worth the pipe Inspection program Inspects and assesses 35 miles of pipe per year.

Information collected during this inspection would help to identify any cleaning needed for pre-cctv purposes, risk exposure, failure, and damage control associated with underground drainage system.

This program will generate a comprehensive database to properly Identify, plan, prioritize, manage or renovate the city’s underground drainage system.

This database will make determinations based on the evaluations performed during the CCTV process.

Stormwater CCTV Program

• Clean
• Repair
• Replace

Inlets - also known as storm drain inlets, curb inlets or catch basins.

Inlet Maintenance
Scheduled maintenance Is essential in keeping our drainage system at maximum capacity reducing flood risk to citizens and businesses.

Stormwater crews inspect and clean more than 30,000 storm drain inlets within the system. Street flooding is often the result of storm drains that are too small to handle heavy runoff.

• Inlets may trap many different types of solids and chemicals that wash off the landscape.
• The debris can range for fine particulates, leaves, gross pollutants, floatables and trash.
• Inlets collect excess stormwater from the street, transition the flow into storm drains. There are three major types of inlets:
• • Grate
  • Curb opening
  • 4-way Inlet

In other cases, though, the drain may need cleaning. Report street flooding and blocked inlets to TPW Customer Service and crews will investigate.

Culverts - type of drain pipe or channel built into roadways, with an opening underneath for water flow.

Culvert Cleaning Program
This program consist of a team Inspecting culverts throughout the year, identifying heavily clogged culverts and prioritizing as needed. High risk locations are also prioritized and Inspected before and after any rain event.

Drainage ditches, often found on roadsides, provide a nearby, safe location for stormwater to go.

The city of Fort Worth has approximately 4,000 culverts within the system.
