# San Diego Construction Insurance for Public Water Infrastructure and City-Land Redevelopment URL: https://mycontractorsinsurancequote.com/california/metros/san-diego Updated: 2026-10-29 · Reviewed by the Principal, Gleason Insurance Brokers, LLC Publisher: My Contractors Insurance Quote, a website of Gleason Insurance Brokers, LLC Two City of San Diego programs set the tone for large projects in this corner of California: Pure Water San Diego, whose Phase 1 is a set of 12 projects built to produce 30 million gallons per day of purified water through new pipelines, tunnels, pump stations and treatment facilities, and Midway Rising, a proposed redevelopment of the roughly 49-acre city-owned Sports Arena site with thousands of apartment homes and a new arena. The first puts contractors into public-works bonding, tunneling and wastewater-adjacent pollution risk. The second puts developers into a phased, multi-building program on public land where a wrap-up and lender and city insurance terms drive the structure. ## Key Decision Points - Pure Water Phase 1 includes pipelines with tunnels, a subaqueous pipeline, pump stations and treatment expansion across several San Diego communities. - Public works subcontracts on a program like this typically require bonds that protect the City and those who supply labor and material. - Tunneling, wastewater-plant work and dewatering raise builders risk and pollution questions that a standard practice program may not answer. - Midway Rising proposes 2,000 affordable and 2,250 market-rate apartment homes plus a 16,000-seat entertainment center on city-owned land. - Phased multi-building programs on public land are frequent wrap-up candidates, but the structure depends on the owner's agreements and lenders. ## Pure Water San Diego Phase 1: What Is Being Built The City describes Pure Water San Diego as an advanced water purification program that will provide nearly half of San Diego's water supply locally by the end of 2035. Phase 1 includes 12 projects intended to produce 30 million gallons per day of purified water. Listed projects include the Morena Pump Station, Morena Pipelines with a Northern Alignment and Tunnels, North City Water Reclamation Plant expansion and a flow equalization basin, the North City Pure Water Facility and Pump Station plus a pipeline with a dechlorination facility and a subaqueous pipeline. The City reports construction of pipelines, pump stations and treatment facilities in Morena, Bay Park, Bay Ho, Clairemont, University City, Miramar and Scripps Ranch. For contractors, that means linear work through dense neighborhoods, tunneling and work inside or beside operating wastewater and water facilities, all under City contracts with their own insurance and bonding specifications. Statewide licensing, public-works bonding and prevailing-wage context for City contracts is summarized on the page for [California construction insurance and public-works rules](https://mycontractorsinsurancequote.com/california). ## Bonds on Pure Water Contracts and Subcontracts Prime contractors on City public works typically post bid security, a performance bond and a payment bond, and many primes pass bond requirements down to major subcontractors. A performance bond protects the City as obligee. A payment bond protects the subcontractors and suppliers who furnish labor and material. Neither is insurance: if the surety pays, the contractor owes it repayment under the indemnity agreement. Program-scale work strains surety capacity. A subcontractor taking on a pipeline segment or pump station package while carrying other backlog should expect its surety to review current financial statements, work in progress and experience with similar underground or plant work. Bringing that package to the surety before bid day avoids a capacity surprise after award. Who a payment bond protects and how claims typically work is explained in [payment bonds for public water and pipeline contracts](https://mycontractorsinsurancequote.com/construction-surety-bonds/payment-bonds). ### Illustrative scenario: Pipeline Subcontractor on Pure Water with a Midway Bid in View An underground contractor wins a subcontract for part of the Morena Pipelines work under a Pure Water Phase 1 prime. The prime requires performance and payment bonds, CPL meeting its flow-down terms and additional-insured status for the City. The contractor's practice CPL excludes known conditions near the reclamation plant connection, so the broker negotiates the wording and confirms dewatering discharge is addressed. The surety reviews the contractor's work in progress before supporting the bonds. Meanwhile, the contractor is pricing off-site utility work for Midway Rising, where an owner-controlled wrap-up may enroll it, so its own GL and CPL will need to coordinate with the wrap-up's exclusions. Move this to another metro and both Pure Water and Midway Rising disappear. ## Tunnels, Treatment Plants and Builders Risk Tunneling and plant work change the property side of the program. Builders risk or contractors equipment coverage for a tunnel segment may need to address tunnel collapse, groundwater inflow and the tunnel boring or microtunneling equipment itself, and some markets apply specific conditions to underground work. Treatment-plant expansions add existing-facility exposure and testing and commissioning of pumps, membranes and controls. The City's contract usually decides who buys builders risk on public works, so read the insurance section before pricing. Where the contractor must provide it, ask whether testing is included, how existing structures are treated and what deductible applies to underground perils. [builders risk for infrastructure and plant work](https://mycontractorsinsurancequote.com/builders-risk-insurance). ## Pollution Exposure on Wastewater-Adjacent Work Pure Water starts with treated wastewater, and several Phase 1 projects sit at or near reclamation and biosolids facilities. Excavation, dewatering and connections to existing lines can release sewage, impacted groundwater or treatment chemicals. A GL policy with a total pollution exclusion may not respond to those claims. Contractors pollution liability is designed for that gap, but forms differ on known conditions, transportation and disposal sites and on whether mold and bacteria are included. Subcontractors should confirm their CPL meets the prime's flow-down requirements before mobilizing. [contractors pollution liability for underground and plant work](https://mycontractorsinsurancequote.com/contractors-pollution-liability-insurance). ## Midway Rising and Building on City-Owned Land The City reports that Midway Rising would redevelop the approximately 49-acre Sports Arena site in the Midway district with 2,000 affordable apartment homes, 2,250 market-rate apartment homes, a 16,000-seat entertainment center replacing Pechanga Arena, 14.5 acres of parks and public spaces, 130,000 square feet of shops and restaurants plus on-site and off-site infrastructure. The City Council declared the land surplus in September 2021, and in September 2025 the project was advancing to public hearings toward final City Council consideration. Check the City's current status before relying on a schedule. A program of this kind usually involves several developers, many buildings and phased financing on public land. The City's agreements, each lender's exhibit and the developers' contracts will set insurance terms. Owner-controlled or contractor-controlled wrap-ups are often evaluated for multi-building programs, and the choice depends on who controls the contracts, how many builders are involved and how completed-operations coverage is extended across phases. How wrap-ups are structured and when they fit is explained in [OCIP and CCIP wrap-up programs for phased projects](https://mycontractorsinsurancequote.com/wrap-up-insurance). ## Bidding the City's Own Construction Contracts Contractors bidding the city's own capital projects meet a separate set of requirements from development permits: bid security, payment and performance bonds, insurance minimums and endorsements, retainage, warranty and small business program rules, set in the city's contract documents and each solicitation. Those terms are set out in [City of San Diego construction contract bonds and insurance](https://mycontractorsinsurancequote.com/construction-surety-bonds/public-agency-contractor-requirements/city-of-san-diego). ## San Diego Unified Projects San Diego Unified prequalifies contractors on larger projects and applies a Project Stabilization Agreement to bond-funded work. Those requirements are set out in [San Diego Unified contractor requirements](https://mycontractorsinsurancequote.com/projects/school-construction/san-diego-unified). ## Airport Projects The airport authority runs its own owner program, safety qualification and airside rules. Those requirements are set out in [San Diego International Airport contractor requirements](https://mycontractorsinsurancequote.com/projects/airport-and-port-construction/san-diego-international-airport). ## Grading and Right-of-Way Permit Bonds Under SDMC 129.0119 Under SDMC Section 129.0119, Grading and Public Right-of-Way Permits are bonded by a California-authorized surety. The schedule sets 110 percent of estimated cost for public improvements and right-of-way restoration and a tiered grading amount (100 percent of the first $5,000, 50 percent to $50,000, 25 percent above). Projects estimated at $100,000 or less are exempt unless the City Engineer requires one. The September 2026 code copy reflects a July 15, 2026, amendment not yet in force in the Coastal Overlay Zone, so confirm with the City. Information Bulletin 126 (July 2026) requires form DS-401 from a surety rated "A" or higher, and bonds stay in force until as-builts are approved and the permit closes. Information Bulletin 353 adds an inspection deposit on deferred construction engineering projects. After a default notice, the surety has 35 days to deposit the completion estimate plus 25 percent. Sureties typically price that tail. How right-of-way permit bonds typically work statewide is explained in [California encroachment permit bonds](https://mycontractorsinsurancequote.com/construction-surety-bonds/encroachment-permit-bonds/california). ## Contractor Lists, Workers Comp Proof and the Permit Indemnity SDMC Section 129.0121 (since October 2022) requires permits for 20 or more dwelling units, 20,000 square feet or more of new floor area or any right-of-way work to list each contractor and subcontractor with workers' compensation policy numbers and expirations, updated before new subcontractors start. Missing this counts as working without a permit. Section 129.0122 (effective October 5, 2024) makes the applicant and owner indemnify the City against suits challenging a construction permit. A GL policy may not respond, so ask counsel how defense would be funded. Chula Vista applies its own right-of-way security and insurance rules, covered in [Chula Vista construction insurance and permit security](https://mycontractorsinsurancequote.com/california/metros/san-diego/chula-vista). ## Assembling a San Diego Program For Pure Water contractors, the core pieces are bonds sized to the package, builders risk or equipment coverage fitted to tunneling and plant work, and CPL that meets the prime's requirements. For Midway-scale developers, the structure decision comes first: wrap-up or traditional, with builders risk, GL and bonds aligned to the City's agreements and the lenders. Collect the contract insurance specifications and bond forms first, then build the submission around them. To review a specific San Diego project, request a quote or call 844-978-7283.

Many primes on City public works pass down performance and payment bond requirements to major subcontractors, along with insurance flow-downs. A performance bond protects the prime or City and a payment bond protects lower-tier claimants. Your surety will review financial statements and work in progress, so share the package before bid day. ### Is tunneling on a water pipeline insured the same way as open-cut trenching? Usually not. Tunneling brings collapse, groundwater inflow and high-value boring equipment into the picture, and builders risk or equipment markets may apply specific conditions or deductibles to underground work. Read the contract to see who must buy builders risk, then ask how tunneling perils and equipment are treated before pricing. ### Why would a contractor need pollution coverage on a water purification project? Several Phase 1 projects connect to wastewater reclamation and biosolids facilities. Excavation, dewatering and tie-ins can release sewage, impacted groundwater or chemicals. A GL total pollution exclusion may block those claims. Contractors pollution liability may respond, depending on known-conditions, disposal and mold or bacteria wording. ### Does a large redevelopment on city-owned land like Midway Rising usually use a wrap-up? It is often evaluated. Multi-building programs with several developers and phased financing can benefit from an owner- or contractor-controlled program, but the decision depends on the City's agreements, the lenders and who controls the contracts. Enrolled contractors still need their own policies for excluded operations and off-site work. ## Official Sources 1.
