The Impact of Winter Weather on Water Systems

Frozen pipe.png

With winter weather upon us, water systems face increased challenges. The combination of freezing temperatures, increased water demand, and potential infrastructure vulnerabilities can significantly impact the quality and reliability of drinking water. Understanding these challenges and how to mitigate them is crucial for ensuring safe and consistent water supply during the colder months.

Freezing Temperatures and Infrastructure

One of the primary concerns during winter is the risk of pipes freezing and bursting. When water inside pipes freezes, it expands, which can cause pipes to crack or burst. This not only leads to water loss but also poses a risk of contamination if the integrity of the water system is compromised. To prevent this, water utilities often implement measures such as:

  • Insulating Pipes and Infrastructure: Ensure that pipes are properly insulated and that heating systems are in place to maintain a stable temperature in critical areas.
  • Regular Maintenance: Conduct regular inspections and maintenance of water systems, including checking for leaks and ensuring that all equipment is in good working order.
  • Heating Systems: Installing heating systems in critical areas to maintain a stable temperature.
  • Communication with Customers: Encourage homeowners to be proactive about protecting their pipes from freezing in colder months.

Increased Water Demand

Winter weather can lead to increased water demand for various reasons, including the need for heating systems that use water, such as boilers and radiators. Additionally, people tend to use more water for hot showers and baths during colder months. This increased demand can strain the water supply system, making it essential for utilities to manage resources efficiently.

Contamination Risks

Snow and ice can carry pollutants, like salt for de-icing roads, that may enter the water supply through runoff. When snow melts, it can pick up contaminants from roads, agricultural fields, and other surfaces, which then flow into water sources. To address this, water treatment facilities must be equipped to handle higher levels of pollutants and ensure that the water is safe for consumption.

Mitigation Strategies

To ensure the reliability and safety of drinking water systems during winter, several strategies can be employed. Organizations should establish a comprehensive cold weather safety plan. This plan should outline precautions to take before, during, and after the onset of freezing temperatures. Key elements include: 

  • Winterize water systems and ensure that exposed plumbing is properly drained. 
  • Inspect building heating systems to keep areas with plumbing above 40°F. 
  • Clear access to fire hydrants, sprinkler system rooms, and life safety equipment.
  • Monitor and manage snow accumulation on roofs and around facilities to prevent damage and ensure safety.
  • Review emergency evacuation procedures to ensure that snow, ice and cold weather conditions are adequately addressed.

Winter weather presents unique challenges for water systems, but with proactive preparation and effective management, these challenges can be mitigated. By understanding the risks and implementing appropriate strategies, we can ensure that our drinking water remains safe and reliable throughout the winter season.

LCRI: Next Steps for Water Systems

pipe with water.png

The recent Lead and Copper Rule Improvements (LCRI) introduced by the EPA mark a significant step towards ensuring safer drinking water across the United States. These improvements require water systems to take several important actions to comply with the new regulations. Below is a guide to help water systems navigate these changes effectively and efficiently.

Develop a Baseline Service Line Inventory: Water systems must create a detailed inventory of all service lines, identifying those made of lead or galvanized steel. This inventory is crucial for planning and prioritizing replacements. The initial inventory was due by October 16, 2024, and must be updated regularly.

Replace Lead Service Lines: One of the core requirements of the LCRI is the replacement of all lead service lines within 10 years. Water systems need to develop a comprehensive replacement plan, secure funding, and begin the replacement process promptly.

Enhanced Testing and Monitoring: The LCRI mandates more rigorous testing protocols to detect lead in drinking water. Water systems must implement these protocols, which include testing at schools and childcare facilities for the first time. Regular monitoring and reporting are essential to ensure compliance and protect public health.

Public Notification and Communication: Transparency is key under the LCRI. Water systems must notify the public about the presence of lead service lines and any exceedances of lead action levels. Effective communication strategies should be developed to keep communities informed about the risks and the steps being taken to mitigate them.

Secure Funding and Resources: Compliance with the LCRI will require significant financial resources. Water systems should explore funding opportunities such as the Drinking Water State Revolving Fund (DWSRF) and grants available under the Bipartisan Infrastructure Law. Developing a robust financial plan is essential to support the replacement and testing initiatives.

Funding can be accessed through several federal programs:

Staff Training and Capacity Building: Ensuring that staff are well-trained and knowledgeable about the new requirements is crucial. Water systems should invest in training programs and capacity-building initiatives to equip their teams with the necessary skills to implement the LCRI effectively.

Engage with the Community: Community engagement is vital for the successful implementation of the LCRI. Water systems should hold public meetings, provide educational materials, and work closely with community leaders to build trust and support for the lead service line replacement efforts.

The Lead and Copper Rule Improvements represent a significant advancement in protecting public health from the dangers of lead in drinking water. By following these steps, and reading EPA's Fact Sheet for further guidance, water systems can ensure compliance with the LCRI and contribute to a safer, healthier future for all communities.

Lead and Copper Pipe Replacement

Blog Post Template - A-Z Lead and Copper.png

Lead and copper enter drinking water primarily through plumbing materials. Exposure to lead and copper may cause health problems ranging from stomach distress to brain damage. The treatment technique for lead and copper requires systems to monitor drinking water at customer taps. If the action level for lead is exceeded, the system must also inform the public about steps they should take to protect their health and may have to replace lead service lines under their control.

We have 521 resources (and counting) on Lead and Copper in our Documents Database that provide valuable information on this topic. You can search for documents on how to collaborate with organizations to replace lead service lines (LSLs), case studies that analyze LSLs in small community water systems, how to reduce lead in drinking water in schools and childcare facilities, how to address lead in drinking water with the Drinking Water State Revolving Fund (DWSRF), and many other useful guides that will help you to deliver safe and clean water to utility customers.
