Alternate Water Supply Systems

Providing Water Supply using a Burrito
Part Five


© 2001 Capt. Willis Lamm, Water Supply Officer, Moraga-Orinda (CA) Fire District

The following procedures are examples of low water pressure evolutions based on the procedures of the Moraga-Orinda Fire District, presented for illustrative purposes.
  DRAFTING FROM THE BURRITO

If the Burrito is being refilled using a shuttle operation, the most efficient pumping operation is via 3" drafting hose. A practical procedure is listed below.

Side Suction Drafting

  1. Insert the length of drafting hose with the strainer into the tank, under the lip.

  2. Pull the engine into approximate position.

  3. Attach the second length of hose to the engine pony suction.

  4. Move the engine into final position to join the two lengths of hose.

    (A double male connector may be required for this connection.)

  5. Close the tank to pump line, fast idle the pump and operate the primer.

    (Priming via the 3" hose is almost instantaneous.)

Front Suction Drafting

    Follow the same procedures as outlined above except make your connection to the front suction.

    (Front suction connections are easier to make and the person handling the hose has better visual contact with the driver.)

Key Points:
  • DO NOT make your last connection to the engine's side suction. If the vehicle has to be repositioned, the driver has the poorest visibility of the person handling the hose at this location.

    Make your final connection by joining up the two lengths of hose.

  • When utilizing the side suction, a little too close is better than too far away. The suction hose can be bent to accommodate a close-in hookup. If the engine is too far away, the strainer will want to surface unless someone holds onto the hose.

  • When drafting from the Burrito, the tank can be dump filled without interrupting the drafting operation.
