Storm Sewer in Texas Part 2 of 7 - The Importance of Extreme Event Overflow

Updated: Oct 5, 2023

Introduction: Storm Sewer Event

Welcome to Part 2 of JRH Engineering and Environmental Services Inc.'s comprehensive series on storm sewer systems in Texas. In this segment, we will delve into a critical aspect of storm sewer design: the importance of addressing extreme event overflow. Texas' weather can be unpredictable, and planning for extreme weather events is essential for effective stormwater management.

Flash Flooding in Texas

Section 1: Understanding Extreme Event Overflow

The Challenge of Extreme Weather

Texas experiences a wide range of extreme weather events, from heavy rainfall to hurricanes, making robust storm sewer systems a necessity.

Flood Prevention

One of the primary objectives of storm sewer systems is to prevent flooding during extreme weather events.

Infrastructure Protection

Storm sewer systems safeguard critical infrastructure, such as roads, bridges, and buildings, during extreme weather conditions.

Section 2: Design Considerations for Extreme Event Overflow

Designing for Resilience

Designing storm sewer systems to handle extreme event overflow requires careful planning and consideration.

Capacity Planning

Assess the capacity of storm sewer systems to accommodate the increased flow during extreme weather events.

Elevation and Egress

Consider the elevation of storm sewer openings and egress points to prevent system overload and flooding.

Emergency Overflow Routes

Design emergency overflow routes to divert excess water safely away from critical areas during extreme events.

Section 3: Emergency Management and Response

Emergency Preparedness

Effective emergency management and response plans are vital for addressing extreme event overflow.

Coordination with Authorities

Coordinate with local authorities and emergency services to ensure a unified response during extreme weather events.

Communication Systems

Implement robust communication systems to disseminate warnings and information to the public during emergencies.

Monitoring and Maintenance

Regular monitoring and maintenance of storm sewer systems are essential to ensure their functionality during extreme events.

Section 4: Community Resilience

Building Community Resilience

Storm sewer systems play a pivotal role in enhancing community resilience in the face of extreme weather events.

Public Awareness

Educate the public about stormwater management and the importance of preparedness during extreme events.

Sustainable Practices

Incorporate sustainable stormwater management practices that minimize the environmental impact of extreme event overflow.


Addressing extreme event overflow is a fundamental aspect of storm sewer design in Texas. Planning for resilience, capacity, emergency management, and community engagement are key components of effective stormwater management during extreme weather events. In Part 3 of our series, we will explore the specific challenges and solutions related to storm sewer maintenance in Texas.
