Springdale St & Westminster Blvd Sewer Manhole Installations Project
Start Date: TBD
Finish Date: TBD
The Midway City Sanitary District (MCSD) owns an 8-inch sewer on Springdale Street, which crosses under a larger 60-inch sewer built by the Orange County Sanitation District (OCSD) in 1970. The crossing has an inverted siphon that doesn't meet industry standards, with a 2-foot vertical drop shown in a 2014 CCTV inspection. The siphon lacks necessary features like manholes, proper slopes, or air jumpers for maintenance. MCSD is working with AKM Engineering firm for Preparation of Plans and Specifications of Construction of Manholes Upstream and Downstream of the Inverted Siphon at Westminster Boulevard and Springdale Street.
The scope of work is as follows:
1. Conduct field surveys to determine sewer elevations at specified manholes.
2. Obtain as-built utility plans for key intersections.
3. Review project site and compare marked utilities to as-built information.
4. Select upstream and downstream manhole locations.
5. Prepare plans, profiles, and specifications, including geotechnical investigation for shoring and dewatering.
6. Identify permit requirements with local authorities.
7. Submit plans and specifications for review and address feedback.
8. Finalize and submit bid-ready documents.
9. Provide support during bidding and engineering services throughout construction, including as-built plans.

RFB - Specifications and Plans for Sewer Manhole Installation Proj.pdf2025-26 Sewer Main Rehabilitation Project
Start Date: 4/28/2026
Approx. Finish Date: 6/12/2026
The scope of work includes the rehabilitation of 35 Vitrified Clay Pipe (VCP) sewer main segments using cured-in-place pipe (CIPP) technology. Of these, 32 segments are 8 inches in diameter totaling 8,330 linear feet, 2 segments are 10 inches in diameter totaling 449 linear feet, and 1 segment is 18 inches in diameter totaling 332 linear feet. CIPP installation shall be performed from manhole to manhole, with the use of end seals to prevent infiltration tracking between the host pipe and the liner, as well as leakage into the CIPP at manhole connections.

Plans.pdfCMSD & MCSD Standard Specifications & Drawings Development Update Project
Start Date: TBD
Finish Date: TBD
This project is a joint effort by the Midway City Sanitary District (MCSD) and Costa Mesa Sanitary District (CMSD) 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 specification per specific agency requirements, and delivering a final set of drawings and specifications to each agency. CMSD will be the project administrator and manager for this project effort.
The overall objective is to develop specific work products for each agency; please refer to the Detailed SOW, Exhibit B, found on CMSD's website linked below.

2026 Sewer System Condition Assessment Project
Start Date: 3/2/2026
Approx. Finish Date: 9/11/2026
In 2024, the Midway City Sanitary District (MCSD) contracted with Empire Pipe Cleaning and Equipment for Closed-Circuit Television (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.
This project is to assess the condition of the pipes and manholes based on the CCTV inspections completed. Structural deficiencies need to be identified, and repair and replacement projects developed. The projects are to be prioritized along with capacity related projects. This will be done by considering the condition, capacity, as well as additional criteria identified in the Statewide Waste Discharge Order 2022-0103-DWQ, and NASSCO PACP/MACP Version 8 standards, including but not limited to:
1. Areas that hold a high level of environmental consequences if vulnerable to collapse, failure, blockages, capacity issues, or other system deficiencies.
2. Vicinity to surface waters, steep terrain, high groundwater levels, or environmentally sensitive areas.
3. Vicinity to receiving waters with bacterial-related impairment.
