REQUEST FOR PROPOSAL

1.0 INTRODUCTION

The City of Rochester (City) Water Bureau is soliciting proposals from an experienced and qualified firm

to provide assistance in corrosion engineering and cathodic protection for both small and large diameter

cast iron (CI), ductile iron pipe (DIP), and steel water mains located in the Upland Transmission System

(Uplands System), Domestic Distribution System (Distribution System), and the Holly Fire System (Holly

System). Work will involve evaluation, recommendation, design and inspection of cathodic protection

systems. Metallic water mains in most cases are buried; however, some may be submerged in water.

This project will be administered and managed

by the Engineering Division of the Bureau. The

Bureau is a unit of the Department of

Environmental Services (DES).

Interested firms shall prepare a comprehensive

proposal for the services required to

successfully perform the scope of work for the

Corrosion Protection Project as described in this

Request for Proposal (RFP).

Firms shall also be prepared to comply with all

the City’s contractual requirements and hiring

practices. The Appendix contains a draft copy of

Article I and Article II of the Professional

Services Agreement (PSA) that will be executed

between the City and the selected Consultant.

Article I of the Agreement will be finalized

during the negotiation process with the

Consultant.

2.0 BACKGROUND

Since 1876, the Water Bureau has been

delivering quality drinking water from Hemlock

and Canadice Finger Lakes to the City. On a

yearly average, the City’s Hemlock Lake Water

Filtration Plant (Hemlock WFP) produces 37

million gallons per day (MGD), which is delivered to the residents and businesses in the City and

wholesaled primarily to the Monroe County Water Authority (MCWA), the Town of Livonia, Livingston

County Water & Sewer Authority and the Town of Lima.

Treated water flows by gravity from Hemlock WFP through a 6-foot x 6-foot horseshoe shaped masonry

brick tunnel for approximately 2 miles to an underground Conduit Header Structure. The tunnel was

constructed in 1894. A 60-inch diameter fiberglass composite pipe was installed in the tunnel in 1991. A

36-inch diameter steel bypass pipe (Tunnel Bypass), which runs parallel of the tunnel, was installed in

RFP – Corrosion Engineering Services

Page 3

1964. An impressed current cathodic protection system was installed on the Tunnel Bypass several years

later.

From the Conduit Header Structure, three conduits (Conduits 1, 2, and 3) extend north to Rush

Reservoir. From Rush Reservoir, all three conduits extend northerly to the City’s Highland and Cobbs Hill

Reservoirs. The conduits range in size from 24-inches to 38-inches in diameter. Conduit 1 was

constructed between 1874 to 1875 using wrought iron and CI pipe. Conduits 2 was constructed between

1893 and 1894, which consists almost exclusively of riveted steel pipe. Conduit 3 was constructed

between 1914 and 1918 using lockbar steel and CI pipe. A 24-inch diameter spiral welded steel pipeline

connecting Conduits 2 and 3 with Conduit 1 (Crossover) was constructed in 1934. The Crossover was

replaced in 2001 with 30-inch diameter DIP. A 9.6 mile section of Conduit 1, between the Conduit

Header Structure and the Crossover, has been taken out of service since the mid-1960s due to extensive

leaking.

The City maintains over 590 miles of water mains of various sizes within the water Distribution System.

The water Distribution System contains over 7,200 fire Hydrants and over 58,000 metered water

services. The Water Bureau provides domestic water and fire-fighting water to the residents of the City

as well as provides water to all industry and businesses located within the City. The City also maintains a

high-pressure firefighting water system that is located primarily within the central business district. This

non-potable water system is referred to as the Holly System. The pump station for the Holly System is

located on Mill Street. The Holly System supplies sprinkler systems and some fire hydrants. This system

consists of approximately 21.4 miles of water mains ranging in size from 4-inches to 20-inches diameter.

Water Main Materials

Maintenance performed on the Conduit System has varied throughout the years. Approximately 22

years after installation of Conduit 1 there were over 1,000 leaks that had been repaired between

Hemlock Lake and Rush Reservoir. The majority of these leaks were on the wrought iron sections and

were primarily attributed to leaking lead joints. Additionally, some corrosion pitting occurred in the

wrought iron piping. Numerous corrosion holes were repaired approximately 7 years after the

installation of Conduit 2. A pipeline exterior recoating operation was started on the conduits, which

continued for more than a decade. Significant portions of the conduits had an application of cement

mortar lining applied to the pipe interior in the 1940s and 1950s. A substantial reduction in the number

of reported leaks was observed several years after the cement mortar lining was installed. By 1974, the

entire Conduit System had received a cement mortar lining.

Besides the cathodic protection system on the Tunnel Bypass, an impressed current cathodic protection

system with sacrificial anodes and test stations was installed on approximately 10 miles of Conduits 2

and 3 in the early 2000s.

Over the years, the existing sections of the 24-inch diameter wrought iron pipe for Conduit 1 has been

replaced, with the last remaining 14,000 linear feet located within the Towns of Rush and Mendon

replaced with a tape wrapped spiral welded steel pipe with a cement mortar lining in 2005.

In 2017, the City engaged a consultant to design on impressed current cathodic protection system for

Conduits 2 and 3 from Sycamore Ridge to the Rush Reservoir in the Towns of Rush and Mendon. The

project was completed in 2021.

Installation of the City’s Water Distribution System began in 1873. CI pipe was the material used up

until the 1970’s when the City started using DIP. Beginning in the mid 1950’s, CI and DIP water mains

were installed with a factory applied cement mortar lining. All of the water mains installed between the

RFP – Corrosion Engineering Services

early 1970’s and 2005 were DIP. From 2005 to the present, Polyvinylchloride (PVC) and Molecularly

Oriented PVC (PVCO) have been predominantly used with limited use of DIP due to external corrosion

and breakage concerns.

In the early 2000’s, the City engaged a corrosion specialist to perform an evaluation of the distribution

system within the City in response to several corrosion related failures of DIP that had been in service

for only 20 years, while much older CI pipe was still in good condition. Some of the original CI pipe is

150 years old and still performing adequately today. Due to the increasing number of failures on DIP

that were only 20 to 30 years old, the City evaluated cathodic protection systems and other pipe

materials for the water distribution system.

In 2005, PVC was included in the City’s approved products list and in 2007 PVCO was added to the list.

PVCO is now the preferred material for water main replacement in the 6 to 12 inch diameter pipe size

ranges. DIP is allowed in areas of high pressure, hydrocarbon soil contamination, and for some water

mains and services. Additional requirements are placed on its use; including, polyethylene wrap,

magnesium anode installation, joint bonding and installation of cathodic protection test stations.

Approximately 25% of the pipe in the City’s water distribution system is DIP or about 150 miles of water

main.
