SUBJECT: AUTHORIZE AND DIRECT THE CITY MANAGER TO EXECUTE A
CONTRACT WITH DOMINGUEZ GENERAL ENGINEERING, INC. FOR
THE WATER MAIN REPLACEMENT PROJECT IN THE AMOUNT OF
$324,055
Recommendation: Approve
SUMMARY
The City of Arcadia's Water Main Replacement Program is designed to replace aged
and deteriorating water main pipes throughout the City's water distribution system. The
water main replacement project identified as a part of the 2012 -13 Capital Improvement
Program (CIP) includes the replacement of the water main and fire hydrants on Tenth
Avenue between Camino Real Avenue and Longden Avenue. The replacement of the
existing cast iron water main with ductile iron pipes will lessen the potential for future
water main breaks and increase the fire flow in the City's water distribution system.
It is recommended that the City Council authorize the City Manager to execute a
contract with Dominguez General Engineering, Inc. for the Water Main Replacement
Project, in the amount of $324,055.
DISCUSSION
The 6 -inch cast iron water main along Tenth Avenue was installed in the 1938. Public
Works Services maintenance crews have frequently made emergency repairs to the
water main along Tenth Avenue. The reason for frequent leaks on this water main is
due to the age and material of the pipe.
Cast iron was a common pipe material due to its strength and corrosion resistance;
however, it is brittle and susceptible to leaks, limiting its durability and reliability.
Pressure fluctuations combined with minor geological movement and settlement can

cause cast iron pipe to break. Ductile iron, which replaced cast -iron as the industry
standard for water pipe, has the corrosion resistance and strength characteristics of
cast iron, but can tolerate movement or deflection without breaking.
The proposed project will replace the existing 6 -inch cast iron water main with a 10 -inch
ductile iron pipe. This will result in improved fire flow and cut down on the potential for
future water main breaks. The results will be improved water flow in the pipes, and
overall reliability of the City's water system in the event of a catastrophic event. The
project will also replace under -sized fire hydrants with a standard 6 -inch fire hydrant that
meets current fire protection regulations.
A Notice Inviting Bids was published in the City's adjudicated paper and bid packages
