Learn how to assess and utilize rural water sources effectively for firefighting operations to ensure a steady supply of water in remote areas.

In rural firefighting, the availability and quality of water sources are crucial to a successful operation. From shallow streams to ponds, evaluating the viability of a water source before drafting is essential for ensuring an uninterrupted water supply to the fireground. This guide explores key factors to consider when assessing rural water sources and offers best practices for using them in firefighting operations.

Identifying Viable Water Sources

In rural environments, water sources can vary greatly in size, flow rate, and accessibility. Before drafting, it’s important to assess the viability of a source based on several factors:

Stagnant vs. Flowing Water Sources

Stagnant water sources, such as ponds, may be less ideal for drafting due to potential contamination or limited volume. Flowing water sources, like streams or rivers, are preferable because they can provide a replenishable supply of water. However, it’s essential to determine the flow rate of the water to ensure it meets the demands of the firefighting operation.

Calculating Flow Rate

To calculate the flow rate of a stream or river, you will need to measure the width, depth, and velocity of the water. By using a buoyant object to gauge velocity and applying a simple formula, you can estimate the gallons per minute (GPM) the source can provide. This information is critical for determining whether the source can support your fireground water needs.

Don’t wait until you’re on an active scene to evaluate the available sources in your response district. Pre-plan!

Tools for Measuring Water Depth & Velocity

Having the right tools on hand is essential for accurately assessing a water source. Common tools include:

Hard Sleeve Sections for Measuring Depth

Hard sleeve sections can be used to measure the depth of a stream or pond. By placing a section on the shore and submerging a buoyant object, firefighters can track how fast the object moves across a known distance, giving them the velocity of the water.

Buoyant Objects for Velocity Measurement

A simple buoyant object, such as a piece of wood or a leaf, can be used to measure water velocity. Time how long it takes the object to move across a designated distance, then use this information to calculate the flow rate of the water source.

Damming Operations for Shallow Water Sources

When faced with a shallow water source that does not have enough depth for drafting, firefighters can use a damming operation to raise the water level. Damming creates enough depth to submerge a strainer and begin drafting operations.

Equipment Needed for Damming

To create a dam, you’ll need basic equipment such as ground ladders, tarps, and hand tools. The ladder and tarp are rolled together and placed across the stream to create a barrier, raising the water level behind the dam.

Placing the Strainer

Once the dam is in place and the water level has risen, firefighters should place the strainer in the deepest part of the water source. Be sure to keep the strainer several feet away from the dam to avoid collecting debris that could clog the system.

Overcoming Challenges Finding Reliable Sources for Rural Water Supply

Evaluating and using rural water sources comes with its own set of challenges. Some common issues include:

Air in the Hard Sleeve

Air can get trapped in the hard sleeve during drafting, causing a loss of prime. Be sure to monitor the intake valve and bleed the line to prevent cavitation and maintain water flow.

Debris in the Water

Debris from natural water sources can clog strainers and disrupt water flow. To minimize this, place the strainer away from the dam and use a jet siphon to clear debris from the intake.

Best Practices for Rural Firefighting Water Source Management

Managing water sources in rural environments requires careful planning and attention to detail. Follow these best practices to ensure a steady water supply:

Pre-Plan Water Sources in Your District in the Hard Sleeve

Before a fire incident occurs, conduct a pre-planning assessment of potential water sources in your district. By identifying reliable water sources in advance, you’ll be better prepared to deploy resources effectively.

Maintain Clear Communication

Effective communication between firefighters at the water source and those at the fire scene is critical. Use radios to keep everyone informed of water levels and flow rates, ensuring that any issues can be addressed quickly.
