REQUEST FOR PROPOSALS

FOR

WATER STORAGE TANK REPAIR AND MAINTENANCE SERVICES

Schedule Number: 5680

I. INTRODUCTION

The City of Redding (City) is soliciting proposals from qualified firms to provide full-

service repairs and maintenance of the City’s eleven (11) potable water storage

tanks/reservoirs (tanks) at various locations throughout the City’s water service area for a

period of up to ten (10) years.

Interested firms are invited to submit proposals, in accordance with the requirements of this

request for proposals (RFP). The goal of this solicitation is to identify the most qualified

firm to provide the scope of services described herein to the highest possible standard and

for an acceptable price, comparable with typical industry pricing.

The City plans to contract with the selected firm (Consultant) for a customized full-service

repair and maintenance program under a fixed and spread-price contract to facilitate all the

repairs and maintenance associated with its potable water storage tanks for the term of the

Contract.

II. BACKGROUND

The City of Redding is located at the northwest end of Northern California’s Central

Valley, approximately 160 miles north of Sacramento and 100 miles south of the Oregon

border. It has a population of just over 95,000, a land area of approximately 60 square miles,

and is one of three incorporated Cities located in Shasta County.

The City of Redding Water Utility provides water to most residents and businesses within

the City. The City’s water system has grown steadily since it was originally incorporated

with the old California Water Service Company system in 1941 and it includes two water

treatment plants, approximately 565 miles of conveyance and distribution pipelines, 17

groundwater wells, ten pump stations, and eleven tanks providing a total of 32.7 million

gallons of storage.

The eleven tanks are located on nine sites throughout the City’s water service area. There

are two tanks located at the City’s Hill 900 and Enterprise tank sites. The City has

designated tag numbers for each tank site, so tanks that share the same site also share the

same tag number. General information for each of the City’s water tanks is provided in the

following Table 1.

For more specific information about each of the tanks, refer to the provided tank schedule

and available record drawings. The tank information provided is believed to be accurate,

based on the information that the City has available. However, the Consultant shall be

responsible for gathering and confirming information during the mandatory pre-proposal

meeting, as described in this RFP, and no change orders will be provided based on

inconsistency in the information provided by the City.

The City has plans to construct an additional storage tank near the Redding Ranchettes tank

and an additional storage tank near the Hill 900 tanks with separate capital improvement

projects during this service contract period. However, it should be assumed that no repairs

or maintenance for these two proposed tanks will be required under this maintenance

contract.

The City has performed cleaning and interior inspection in each of its tanks on an

approximately five-year interval with the most recent cleaning and inspection effort

performed in the winter of 2021. There were no significant deficiencies noted or repaired on

the interior of the tanks during the 2021 cleaning and inspection. There are existing coating

failures and possible corrosion. See provided inspection reports for additional information.

An overall map of the City’s water system, pressure zones, treatment plants, and storage

tank locations is provided in the following Figure 1.
