The purpose of the Program is to enforce the Non-potable Water Ordinance (NPO) and ensure that development projects required to comply with the ordinance are treating and reusing alternate water sources onsite for the life of the building.
Who Must Comply?
New development projects that apply for a site permit after January 1, 2022 of 100,000 gross square feet or more.
Mandatory NPO projects are subject to the NPO Excess Use Charge Program. Each mandatory project will be assigned a potable make-up water allocation. Any potable water use that exceeds the allocation will be billed at 3x the applicable water and wastewater rates.
Projects will be eligible to begin incurring excess use charges 1 year after the building reaches 25% occupancy. A project will be classified as having 25% occupancy when the billed monthly water usage is greater than 25% of the total predicted monthly water use as documented in the Water Budget Documentation and Water Use Calculator for 3 consecutive months.
Projects must submit to the SFPUC monthly documentation of the volume of non-potable water produced by their system and potable make-up water used. This data should be collected from the 2 flow meters required for all projects by San Francisco Department of Public Health Rules and Regulations.
Data must be submitted by the 15th of each month for the previous calendar month. Projects will need to reference their Account ID each time they submit data. If you have questions about submitting data or have issues with the form for submission, please contact email@example.com.
Request Revised Potable Make-up Allocation
Projects may request a revised Potable Make-Up Allocation if the project’s current allocation is not representative of the customer’s actual NPO Supply and/or actual NPO Demand. This includes situations where circumstances affecting the customer’s water use practices, such as occupancy or zoning, have significantly altered the customer’s water usage since the approval of the Water Budget Documentation.
Projects may request a temporary revision (see NPO Allocation Revision Form) if the project has less than 6 months of continuous data. If more than 6 months of continuous data is available, a permanent revision may be requested.
Projects must submit the NPO Allocation Revision Form. A determination will be made by the SFPUC Assistant General Manager for Water about whether a revised allocation is warranted.
Temporary Suspension Request
Projects may request to temporarily suspend operation of the onsite water reuse system if circumstances beyond the reasonable control cause the system to be inoperable for more than 30 days using the NPO Temporary Suspension Request Form.
Appeal Excess Use Charge
If a project can demonstrate that they have been incorrectly charged excess use charges, the project can appeal the charges. Projects must submit an appeal within 30 days of receiving an excess use charge using the NPO Excess Use Charge Appeal Form.
