INTRODUCTION

The Costa Mesa Sanitary District (hereinafter referred to as “District”) is soliciting proposals

from qualified Proposers consisting of consulting firms, contractors, and/or teams to prepare

a short-circuit breaker coordination study and arc-flash analysis (Study Report) for seven (7)

District pump stations.

BACKGROUND

The Costa Mesa Sanitary District (CMSD) is an independent special district that was formed

in 1944 under the Sanitary District Act of 1923. It is governed by an elected five-member

Board of Directors that appoints a general manager to supervise the day-to-day operations of

the organization. The District boundaries encompass all of the City of Costa Mesa, a portion

of Newport Beach, and some unincorporated Orange County territory; serving a population

of approximately 116,700 and serving close to 4,000 businesses.

Wastewater is conveyed via 224 miles of collection system and 20 lift stations to OC

Sanitation, the regional wastewater treatment provider. CMSD total daily dry weather flow is

approximately 10 million gallons per day.

The District has determined that a Study Analysis must be conducted for the seven (7)

pump stations: 21st Street PS, 23rd Street PS, Adams PS, Canyon PS, Mendoza PS, Sea

Bluff PS, and Victoria PS. The Study Report is being conducted to determine the arc-flash

and short-circuit potential so that OSHA and Fire Code required warning information labels,

including personal protection equipment requirements, must be placed on the field switch

gear/electrical boxes.

Station Overview & Location(s)

1) The 21st Street pump station comprises two 10hp submersible pumps. The utility provides

240v power to the station. This station is located at 114 East 21st Street, Costa Mesa, CA

2) The 23rd Street pump station comprises two 20hp submersible pumps. The utility

provides 240v power to the station. This station is located at 2401 East 23rd Street,

Costa Mesa, CA

3) The Adams pump station comprises two 20hp submersible pumps. The utility provides

240v power to the station. This station is located at 2054 Adams Ave, Costa Mesa, CA

4) The Canyon pump station comprises two 20hp submersible pumps. The utility provides

480v, 3-phase power to the station. This station is located at 999 Canyon Ave, Costa

Mesa, CA

5) The Mendoza pump station comprises two 10hp submersible pumps. The utility provides

240v power to the station. This station is located at 2899 Mendoza Drive, Costa Mesa,

STUDY ANALYSIS GOAL

Conduct analysis, monitoring, review of the existing facilities, among other activities so that

a Study Report documenting the Breaker Coordination and/or Arc-Flash Analysis work

results. The goal is also for identifying and installing labeling to meet the various safety

regulations and requirements. The Study Report outcome will be used for the purpose of

installing electrical labeling per CalOSHA/OSHA, NFPA, and NEC requirements. The final

outcome will be for the District to obtain one (1) Study Report and have arc-flash warning

information installed at each station.
