INTRODUCTION

The Costa Mesa Sanitary District is soliciting proposals from qualified professional

engineering consulting firms (Proposers) to prepare standard drawings and

specifications for the Costa Mesa Sanitary District (CMSD) and the Midway City

Sanitary District (MCSD).

CMSD will be the Project administrator and manager for this Project effort. Invoices

must be submitted to CMSD for processing and payment. MCSD will reimburse CMSD

for their portion of the work conducted, therefore CMSD will pay the total invoice amount

to the Consultant. CMSD usually pays on a net 30-day basis.

This project is a joint effort by the two Districts for the purpose of developing and

updating standard drawings and specifications and sharing the costs. The Scope of

Work (SOW) generally consists of an engineering consulting firm developing and

updating standard drawings and specifications for the two agencies, tailoring the joint

drawings and specifications per specific agency requirements, and delivering a final set

of drawings and specifications to each agency.

The overall objective is to develop specific work products for each agency; refer to the

Detailed SOW, Exhibit B, below. The estimate for this work is $85,000.

BACKGROUND

The CMSD and the MCSD are independent special districts that were formed by State

legislation and/or Acts. These agencies are governed by an elected Board of Directors

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

organization.

The CMSD encompasses the City of Costa Mesa, portions of Newport Beach, and a

small, unincorporated area of Orange County. CMSD serves a population of

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

The MCSD encompasses the entire City of Westminster and the community of Midway

City, an unincorporated area of Orange County. MCSD serves a population of

approximately 99,700, and close to 3900 businesses.

Wastewater is conveyed to an OC Sanitation regional sewer trunkline(s) and treatment

plant (located in either Huntington Beach or the Fountain Valley). Each agency is the

local sewer collections agency.

PROJECT GOAL

Delivering a set of standard drawings and specifications for each agency during or

before August 2026.
