01160.00 1036 Section 01160 - Hydrants and Appurtenances Description
01160.00 Scope - This Work consists of furnishing and installing hyd rants and appurtenances in
potable water systems at the locations shown or at other locations as directed. Materials
01160.10 Materials - Furnish Material s meeting the following requirements:
Bollards ...................................................................................................... 00815 Commercial Grade Concrete in Thrust Blocking ........................................ 00440 End Connections ................................................................................... 02485.20 Gate Valves ........................................................................................... 02480.20 Hydrants ................................................................................................ 02485.10 Hydrant Extensions ............................................................................... 02485.40 Tie Rods ................................................................................................ 02485.60 Traffic Flange ........................................................................................ 02485.50 Valve Boxes .......................................................................................... 02480.25 Valve Stem Extensions ......................................................................... 02480.26
01160.11 Handling of Hydrants :
a.Loading and Unloading - Handle hydrants to prevent damage to the hydrant, lining or coating. Load and unload hydrants using hoists and slings so as to avoid shock or damage, and under no circumstances allow them to be dropped, skidded, or rolled agai nst other hydrants. Damaged hydrants will be rejected. If damage is confined to the coating or lining, it may be repaired in a manner satisfactory to the Engineer. Immediately place all damaged hydrants apart from the undamaged hydrants and remove the d amaged hydrants from the Project S ite.
b.End Caps - Provide factory applied end caps on pipe connection end s. Maintain end cap s through shipping, storage, and handling to prevent damage and prevent dirt and moisture from entering the hydrant s. Constr uction
01160.40 Setting Hydrants - Inspect all hydrants upon delivery in the field to ensure proper working
order. Install hydrants as shown or directed.
a.Touchup Painting - After all installation and testing is complete, paint the exposed portion of the hydrant with one coat of the type and color of coating designated by the Engineer.
b.Out -of-Service Hydrants - Identify all hydrants not in service by covering with a properly secured burlap or plastic bag.
01160.41 Hydrant Laterals - Install hydrant laterals, consisting of ductile iron pipe, from the auxiliary
gate valve at the main to the hydrant, according to Section 01140 and as shown.
01160.42 Hydrant Restraints - Restrain the thrust created in the hydrant lateral as shown.
01160.43 Gate Valves and Valve Boxes - Install gate valves and valve boxes according to
Section 01150, except that the end connections shall be provided with lugs for tie rods, or the bells shall provide sufficient clearance between the body of the valve and the hub to permit the installation of tie rods. 01160.90
01160.44 Hydrant Bollards - Construct hydrant bollards according to Section 00815 at the locations
shown.
01160.46 Moving Existing Hydrants - Move existing hydrants where shown. As shown, r emove
the existing hydrant lateral tee from the main if the main is to remain active, and insert a new section of pipe into the water main in place of the existing hydrant lateral tee. Where the existing main to which the existing hydrant lateral tee is connecte d is to be abandoned or temporarily activated after the existing hydrant is moved, plug the open end of the hydrant lateral pipeline. Provide temporary thrust restraint if temporarily reactivated.
01160.47 Reconnecting Existing Hydrants - Reconnect exi sting hydrants where shown. Leave the
location and elevation of the existing hydrant unchanged, but change the existing hydrant lateral to connect with a new gate valve and hydrant tee provided in a new main. Install new hydrant lateral according to Sect ion 01140 where the lateral extends to connect to the new main. Where existing hydrants were not restrained, restrain the new connections as shown.
01160.48 Hydrant Extensions - Install hydrant extensions where required.
Field Testing Installations
01160.50 General - After installation, operate hydrants from full open to full closed to ensure that
they do not bind during operation. Correct all malfunctions in the operation of the hydr ants.
01160.51 Hydrostatic Testing - Perform hydrostatic testing of hydrants according to 01140.51.
Correct all defects in Materials or workmanship to the satisfaction of the Engineer.
01160.52 Disinfecting - Disinfect hydrants according to 01140.52.
