Flood-prone areas in Sanford, NC, face unique and significant challenges when it comes to managing sewage systems. Flooding not only overwhelms sewer infrastructure but also increases the risk of contamination, backups, and environmental hazards. These challenges affect property owners, municipal systems, and the broader environment, making proactive management essential for reducing the impact of floods on sewage systems.
This article examines the specific issues faced by flood-prone areas in managing sewage, the risks associated with inadequate solutions, and strategies for mitigating these challenges. (Learn more)
How Flooding Impacts Sewage Systems
Flooding occurs when heavy rainfall, snowmelt, or rising water levels inundate properties and urban infrastructure. For sewage systems, flooding introduces the following challenges:
1. Overwhelmed Sewer Lines
Excess water from flooding can enter sewer systems, exceeding their designed capacity. This often leads to backups and overflows in properties and streets.
In combined sewer systems, where stormwater and sewage share the same pipelines, heavy rainfall compounds the problem by adding massive volumes of water to already stressed systems.
2. Sewage Backups
Floodwaters create pressure imbalances that push sewage back into homes and businesses through drains, toilets, and sinks.
Properties in low-lying areas or with basements are particularly vulnerable to sewage backups during floods.
3. Contamination of Floodwaters
Floodwaters often mix with untreated sewage, carrying harmful pathogens, chemicals, and waste. This contaminated water poses significant health and environmental risks.
Standing floodwaters containing sewage can infiltrate soil and groundwater, leading to long-term contamination.
4. Damage to Infrastructure
Flooding damages sewer infrastructure, including pipes, pumping stations, and manholes. Corrosion, cracks, and pipe collapses are common in flood-prone areas, reducing the system’s efficiency.
Rising water tables can infiltrate sewer lines through cracks, adding to the system's load and causing persistent issues even after flooding subsides.
5. Power Outages
Flooding often leads to power outages, disrupting the operation of pumping stations and wastewater treatment facilities.
Without functional pumps, sewage systems cannot manage the additional water load, leading to backups and overflows.
Unique Challenges for Properties in Flood Zones
Properties located in flood-prone areas face specific sewage management challenges that require tailored solutions. These include:
1. Frequent Exposure to Sewage Contamination
Flood-prone properties are more likely to experience repeated incidents of sewage backups and overflows, increasing the risk of exposure to harmful pathogens.
Cleanup and restoration efforts after each flood event can be costly and time-consuming.
2. Basement Vulnerabilities
Basements in flood zones are particularly at risk of sewage infiltration due to their lower elevation relative to sewer lines.
Water and sewage entering basements during floods can cause extensive structural damage and create ideal conditions for mold growth.
3. Insufficient Drainage Systems
Properties in flood-prone areas may rely on outdated or undersized drainage systems that are ill-equipped to handle the increased water volumes during storms.
Poor drainage exacerbates the risk of water pooling, further stressing sewer lines.
4. Health and Safety Concerns
Residents and property owners in flood zones are at higher risk of exposure to sewage-contaminated water, which can cause illnesses such as gastrointestinal infections, hepatitis, and respiratory issues.
Standing water contaminated with sewage also attracts pests, including rodents and insects, compounding health risks.
5. Increased Maintenance and Repair Costs
Frequent flooding accelerates wear and tear on private sewer lines, septic systems, and household plumbing.
Property owners face higher maintenance and repair costs due to recurring damage.
Environmental Impacts of Flood-Related Sewage Issues
Untreated sewage discharged during floods pollutes rivers, lakes, and streams, introducing harmful chemicals, pathogens, and debris.
Polluted waterways affect aquatic ecosystems and reduce water quality for human and agricultural use.
2. Soil Contamination
Floodwaters containing sewage seep into soil, contaminating agricultural land and reducing its fertility.
Soil contamination can persist long after floodwaters recede, requiring costly remediation.
3. Habitat Destruction
Flood-related sewage overflows disrupt natural habitats, affecting the survival of plants and wildlife.
The spread of pollutants and sediment can alter ecosystems and harm biodiversity.
Strategies for Managing Sewage in Flood-Prone Areas
Effectively managing sewage in flood-prone areas requires proactive planning, infrastructure improvements, and community education. Key strategies include:
1. Improving Sewer Infrastructure
Increase Capacity: Expand the capacity of sewer systems to handle higher water volumes during flood events.
Install Backwater Valves: Backwater valves prevent sewage from backing up into properties by allowing water to flow in only one direction.
Repair and Upgrade Pipes: Replacing aging or damaged pipes with more durable materials can reduce vulnerabilities to flooding.
2. Enhancing Stormwater Management
Green Infrastructure: Solutions such as rain gardens, bioswales, and permeable pavements absorb stormwater and reduce the strain on sewer systems.
Retention Ponds: Create retention ponds to capture excess stormwater, preventing it from overwhelming sewer systems.
Regular Drain Cleaning: Clearing debris from storm drains ensures efficient water flow during floods.
3. Floodproofing Properties
Elevate Utilities: Raising electrical panels, HVAC systems, and sewer cleanouts above flood levels protects them from damage.
Seal Basement Openings: Waterproofing basement walls and installing sump pumps help reduce the risk of flooding and sewage backups.

4. Community Education
Proper Waste Disposal: Educate residents about the importance of not flushing non-biodegradable items or pouring grease down drains, which can exacerbate blockages during floods.
Flood Preparedness: Provide information on steps property owners can take to protect their homes from sewage-related issues during floods.
5. Emergency Response Planning
