Summary
New subdivisions inside a City-Designated Water Reuse Area must use EBMUD recycled water for common-area irrigation and install a separate plumbing system for it, under Municipal Code Section 30-57.5. The City Engineer can exempt a project if recycled water use is technically infeasible or not economically justified.
New industrial, commercial or residential subdivisions that are within the City-Designated Water Reuse Area for which a tentative map or parcel map is required, shall use recycled water provided by EBMUD, and have a separate plumbing system to serve recycled water uses in the common areas of the subdivision, including, but not limited to, golf courses, parks, greenbelts, and landscaped medians. This system must be independent of the provided plumbing system serving the domestic, residential, and other potable uses in the subdivision.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 74).
Full Breakdown
Alameda's Water Reuse Ordinance, codified at Section 30-57 and originally adopted by Ordinance No. , ties the City's recycled-water program to the East Bay Municipal Utility District's (EBMUD) service areas. 4 provides that any EBMUD Designated Water Reuse Area automatically becomes the City-Designated Water Reuse Area unless the City Council specifically narrows it, and the City keeps the boundary descriptions on file with the Public Works Department. 5, Development Applications, sets the operative mandate: new industrial, commercial or residential subdivisions that are within the City-Designated Water Reuse Area for which a tentative map or parcel map is required shall use recycled water provided by EBMUD, and have a separate plumbing system to serve recycled water uses in the common areas of the subdivision, including golf courses, parks, greenbelts, and landscaped medians.
That dual-plumbing system has to stay fully independent of the potable water system serving homes and businesses in the subdivision. 6 requires a written agreement between that supplier and EBMUD before service can begin. 7 gives the City Engineer discretion to exempt a qualifying subdivision from the recycled-water mandate if an alternative higher or better use exists, the recycled-water use isn't economically justified, or it's technically infeasible, but any such exemption must be reported to the Planning Board and City Council.
Violations & Fines
A qualifying subdivision that skips the required recycled-water plumbing without an approved Section 30-57.7 exemption does not get its tentative or parcel map approved, since the dual-system requirement attaches directly to that map-approval process. The City Engineer, not the developer, decides whether an exemption applies, and any exemption granted must be reported to the Planning Board and City Council.
