I. INTRODUCTION.

The Midway City Sanitary District (“District” or “Owner”) invites qualified and experienced firms

(“Contractor” or “Proposer”) to submit proposals to provide comprehensive professional services

for the District’s 2026 Sewer System Condition Assessment Project (“Project”).

The Project seeks to evaluate the condition of the District’s wastewater collection system by

analyzing the Closed-Circuit Television (CCTV) and manhole inspection data completed by the

District’s contractor Empire Pipe Cleaning and Equipment company, in January 2025. Using these

existing datasets, the selected Contractor will assess structural and operational deficiencies,

perform risk-based prioritization, and develop a 5- and 10-year Capital Improvement Plan (CIP)

consistent with State Water Resources Control Board Order No. 2022-0103-DWQ and NASSCO

PACP/MACP Version 8 standards.

The selected Contractor will play a critical role in advancing the District’s proactive asset

management strategy by identifying system vulnerabilities, recommending targeted rehabilitation

and maintenance approaches, and supporting long-term infrastructure planning. This effort is

essential to reducing the likelihood of sanitary sewer overflows, ensuring regulatory compliance,

and strengthening the District’s commitment to protecting public health and the environment.

A. Background.

The District is an independent California special district established in 1939 under the Sanitary

District Act of 1923 (Health & Safety Code §§ 6400 et seq.). The District provides essential

sanitary sewer services to the residents and businesses of the City of Westminster and the

unincorporated community of Midway City in northwestern Orange County. District operations

are headquartered at 14451 Cedarwood Street, Westminster, CA 92683.

Serving a diverse and densely populated region, the District is responsible for the operation and

maintenance of an extensive wastewater collection system. This includes approximately 164 miles

of gravity sewer pipelines, which convey an average of 10 million gallons of wastewater per day

to regional treatment facilities. The District serves a population of approximately 99,000 residents,

and the total value of its sewer infrastructure is estimated at 588 million dollars, representing a

critical public asset requiring careful management and ongoing investment.

In 2024, the District contracted with Empire Pipe Cleaning and Equipment for CCTV inspection

of all sewer pipes and manholes. The work was completed in January 2025. It included CCTV

inspection of 851,187 feet of gravity sewer mains and Level 2 inspections of 3,216 manholes, per

National Association of Sewer Services Companies (NASSCO) standards.

B. Purpose of the Request.

The District is seeking the services of a qualified Consultant to perform a comprehensive condition

assessment of its wastewater collection system using existing CCTV and manhole inspection data,

in alignment with Order No. 2022-0103-DWQ, NASSCO PACP/MACP Version 8 standards, and

the practices outlined in the District’s Sewer System Management Plan (SSMP).

The selected Consultant will provide all labor, equipment, materials, and technical expertise

necessary to validate inspection data, identify structural and operational deficiencies, conduct risk-

based evaluations, and develop prioritized rehabilitation, maintenance, and capital improvement

recommendations.

The primary objective of this effort is to enhance the District’s proactive asset management

strategy, reduce the likelihood of sewer system failures or overflows, and ensure continued

compliance with all applicable regulatory and environmental requirements while supporting long-

term infrastructure reliability.

II. SCOPE OF SERVICES.

The attached Exhibit “A” contains a list of major work tasks that should be accomplished as part

of the scope of work. Proposers are asked to define the approach and the specific scope of work

and methodology to achieve the objectives presented in this RFP. Proposers should include a

refined scope of work by developing a detailed description of all Project tasks and any changes,

additions or recommendations proposed. The description of each Project task should include

specification of the task itself, the methodology or analytical process, scheduling, personnel, and

costs.

The following information is provided to assist proposers in developing their proposal.

A. Structural and Maintenance Ratings

Ratings for sewer mains and manholes are available in spreadsheet format from the District.

B. CCTV Video Access

All CCTV inspection videos are uploaded to the SewerAI website. Access will be granted to the

awarded Consultant through the District’s office. Proposers should review SewerAI’s capabilities

that will assist with completion of this Project.

C. CCTV Inspections of Sewer Gravity Mains

The Scope of Work includes overall review of approximately 851,187 feet of sewer gravity mains

in accordance with NASSCO standards, totaling approximately 3,685 CCTV inspections. All

NASSCO ratings are available. The breakdown of inspection types is as follows:

• 127 inspections are Structural Level 5.

• 448 inspections are Structural Level 4.

• 86 inspections are Maintenance Level 5.

• 387 inspections are Maintenance Level 4.
