SP-07 WATER FOR CONSTRUCTION

Water for construction is the Contractor’s responsibility. The Contractor shall make all necessary arrangements as such. The Contractor is responsible for providing all required fittings, meters, hoses, backflow assemblies, valves and other appurtenances required for obtaining water for construction.

If water is acquired from metered fire hydrants, Contractor needs to know and understand proper hydrant operation procedures as they are the party ultimately responsible for improper hydrant connections or any other improper operation of a hydrant. The contractor is responsible to teach proper operation procedures to all employees using hydrants. This includes water truck drivers or any other employees of the company that operate hydrants for any reason.

Meter Hydrant Connection Procedures

1. Perform a safety check of the hydrant. Check the hydrant visually, and shake the hydrant with your hands to make sure it is rigid (do not use a movable hydrant – they are dangerous and serious injury to the operator may result). Check the hydrant to ensure the caps are tight.

2. Remove hydrant nozzle cap.

3. Attach metering device and hose and install brace support. All hydrant connections must include a RPZ backflow assembly or device acceptable to the CO at all times.

4. Open hydrant slowly. It should take more than 60 seconds to fully open to prevent surging on the water system. Open completely to shut off drip drain while hydrant is in use. Valves downstream of the hydrant shall not be used to control flow.

5. They discharge end of the hose should not be inserted under any circumstances, into a tank or container underwater or laid on the ground to make and lay in its own pool of water. There must be at all time an air gap between the end of the water hose and the container.

6. Upon filling the tank or upon completion of the permitted use, slowly close hydrant valve.

7. Remove hose

8. Replace nozzle cap and tighten securely.

9. No hydrant shall ever be left without the cap replaced and securely tightened.

The Contractor is required to obtain written permission for obtaining water from any public or private water system and provide documentation to the Government.
