What Managers and Associations Say

Read more reviews →See photos of our work →
  • Our HOA manager recommended CPI when our toilet overflowed on a Saturday evening in July. They picked up the phone at 8:30pm on a Saturday night. One of their plumbers showed up 30 minutes later. He quickly determined that the clog was a bigger issue further down the sewer line which required a professional hydro jetting cleaning to resolve. After checking with the HOA manager, CPI sent a jetter machine and another plumber within half an hour. Their crew worked until 11:30pm to clear the clog. We were so happy that we could use the bathroom again! CPI was responsive, communicated well, worked fast, and resolved the issue during off-hours. We will definitely call them again.

    Hattie C.Yelp review

  • CPI has again done a top-rate job of storm season preparation for our complex, video inspections and hydrojetting all the drain lines and sewer lines too. They work hard and efficiently. Especially appreciated their extra effort to finish up before the Thanksgiving holiday with all the friends and family gatherings— Luis took a moment as he was finishing up and gathering up his equipment to say all looked good with a sewer line that had been questionable and that we should be good now for all those big holiday get-togethers.

    Lucinda C.Yelp review

  • CPI and Alex were extremely helpful when our local church’s water heater kept malfunctioning and needed replacing. From the initial diagnosis, explanation and recommendation of replacement, we always felt that our needs were being tailored to. Not only were they extremely kind, knowledgeable and professional, but they also were diligent and efficient during their time.

    We’re truly grateful for their excellent work and would highly recommend CPI to anyone in need of plumbing or heating services, especially for those in larger community buildings like churches like ours.

Commercial Plumbing in Alameda: What's Different

Alameda's water comes from EBMUD and its electricity from the City's own utility, while City Public Works runs the sewers, so several rules differ from neighboring cities.

  • Two numbers for emergencies

    Water main breaks go to EBMUD Emergency Dispatch at 1-866-403-2683, 24/7. Sewer spills and backups go to Public Works at (510) 747-7930; after hours, Police Dispatch at (510) 337-8340 reaches the on-call crew.

  • The City maintains the lower lateral

    The owner maintains and replaces the upper lateral on private property. The City maintains the lower lateral, from the property line to the main, and requires a capped cleanout at the property line.

  • EBMUD lateral certificates

    Alameda joined EBMUD's regional program in 2015. An EBMUD compliance certificate is needed to sell a property, for building or remodeling over $100,000, and when the water meter size changes.

  • Grease devices and EBMUD inspections

    The City's Building Department decides whether a new or modified food business needs a grease control device and inspects the installation. After that, EBMUD carries out the inspections.

  • Express permits online

    Water heaters (tank, tankless and heat pump) and plumbing upgrades and repairs are on the City's list of Express permits: applied for online, with no plan check. Contractors need an Alameda business license.

  • Alameda Municipal Power rebates

    AMP offers business customers a rebate for replacing a gas tank water heater with a heat pump unit. Pre-approval from AMP is required before installation; check AMP for current amounts.

A Property Manager’s Guide to Plumbing in Alameda

Water from EBMUD, sewers from the City

Alameda’s water comes from the East Bay Municipal Utility District (EBMUD). The sewers belong to the City: Public Works operates about 138 miles of City-owned sewers and 46 pump stations, and the oldest pipes are terra cotta laid between 1890 and 1920. Wastewater flows into EBMUD’s interceptors and is treated at EBMUD’s main plant near the Bay Bridge. That splits emergency calls in two. Save both numbers with your building’s emergency contacts:

  • Water main breaks: EBMUD Emergency Dispatch, 1-866-403-2683, 24/7.
  • Sewer spills and backups: City of Alameda Public Works, (510) 747-7930, Monday to Friday, 8 a.m. to 6 p.m. After hours, call Police Dispatch at (510) 337-8340, which contacts the on-call Public Works crew. Backups can also be reported through SeeClickFix.

Sewer laterals: who maintains what

In Alameda, the owner maintains and replaces the upper lateral, on private property. The City maintains the lower lateral, from the property line to the main, and rehabilitates it when the main is rehabilitated or the lower lateral fails. Under Alameda Municipal Code §18-5, a lateral should be free of roots and grease, watertight, and have no roof drains, area drains or sump pumps connected. It also needs a capped cleanout at the property line (or at the sewer main easement); if there isn’t one, the City requires the owner to install it, at a location set by the block’s property-line setback from the curb.

Ground plumbing repairs and replacements need a City Building Permit. A Public Works Encroachment Permit is also needed when the cleanout goes in the sidewalk or parkway strip, or when the lateral runs to a side- or back-yard main. See commercial sewer repair.

EBMUD compliance certificates

Alameda required lateral testing at property transfer from 1988 and joined EBMUD’s Regional Private Sewer Lateral program on January 1, 2015. An EBMUD compliance certificate, issued once the lateral passes an EBMUD inspection showing it is leak-free, is needed:

  • to sell a property (it is required to close escrow);
  • for building or remodeling work over $100,000, at final permit sign-off;
  • when the water meter size changes.

If a sale has to close first, EBMUD sells a Time Extension Certificate with a $4,500 refundable deposit; the City cannot grant extensions. HOAs and other common interest developments had to certify the laterals they maintain by July 12, 2021, and those that haven’t should file EBMUD’s Statement of Responsibility form. At Alameda Point, EBMUD requires an Alameda Point PSL form signed by the City before it schedules certification; start with Public Works Engineering. A camera inspection before a sale or remodel shows whether a lateral is likely to pass.

Restaurants and grease

Alameda has no grease ordinance of its own yet; the City contracts with EBMUD for its grease (FOG) source control program. The City’s sewer plan says food service establishments must have grease interceptors under the California Plumbing Code. For new or modified food businesses, the Building Department decides what grease control device is needed and inspects the installation; after that, EBMUD carries out inspections and issues the first notices of violation, with further enforcement by the City. Grease caused 20 of the City’s 36 sewer spills in the five years to July 2024, and the historic trouble spots are the restaurant districts on Park Street, Webster Street and at the Town Centre shopping center. EBMUD offers free trap and interceptor maintenance guides and a sample maintenance log. Between pumpings, scheduled hydro jetting keeps kitchen lines open.

Backflow testing for EBMUD

EBMUD’s cross-connection specialists inspect sites to decide whether a backflow assembly is needed, for example where the water system connects to a boiler, cooling tower, or booster or recirculating pump, or where there is a well. Once required, the assembly must be installed and tested within 30 days. Only testers on EBMUD’s approved list may test, and the completed form goes back by mail within 30 days of the notice. New fire services are flushed only with EBMUD’s Backflow Section present, on at least 48 hours’ notice. Questions go to 510-287-0874. We install and repair the assemblies these rules require; see backflow preventers.

Permits for plumbing work

The City’s Permit Center (2263 Santa Clara Ave., Room 190; (510) 747-6800; permits@alamedaca.gov) takes applications only through the Accela Citizen Access portal. Water heaters (tank, tankless and heat pump), plumbing upgrades and repairs, and water services are listed as Express permits, with no plan check or drawings; work that needs plan review goes through a Building Pre-Application. Replacing or relocating water, sewer, drain or vent piping is not an exempt repair. If equipment is replaced in an emergency, the permit application is due by the next business day. Contractors need a current City of Alameda business license. Inspections are scheduled at (510) 747-6830.

Water heaters: soft water and AMP rebates

EBMUD’s main supply is Mokelumne River water stored in Pardee Reservoir. Alameda is in the area served by the Orinda treatment plant, which measured 14–40 ppm (1–2 grains per gallon) hardness in the 2025 water quality report; EBMUD notes that areas can be served from a different plant during high demand or maintenance. Scale is usually a smaller concern than in hard-water cities.

Electricity comes from Alameda Municipal Power (AMP), the island’s community-owned utility since 1887. AMP offers business customers on rate codes A1, A2, A3 or M1 a rebate for replacing a gas tank water heater with a heat pump unit. The rebate is based on tank size plus infrastructure and engineering costs, within AMP’s caps; check AMP’s business rebates page for current amounts. Panel upgrades on the customer’s side can count toward eligible costs. AMP must pre-approve the project before installation, and new construction is not eligible. See commercial water heaters.
