A Cal Water rebate is a cash incentive. Your water agency pays it when you install a qualifying water-saving device. For a smart water meter, agencies use a different name: a flow monitoring device. Two programs do most of the work in California. SoCal Water$mart (2026) is run by the Metropolitan Water District of Southern California. The EBMUD Flowmeter Rebate Program covers the East Bay. This guide walks the whole Cal Water rebate application, step by step. It also shows how a Bluebot meter earns the rebate. Bluebot clamps onto the outside of the pipe you care about, indoors, in the irrigation valve box, or on the line to the ADU, with no cutting and no plumber. That is what makes it eligible in the first place: agencies pay for a device that monitors water on your property, not on their meter.
Most of the work happens before you buy. Pick the right agency, check its qualifying list, then keep the paperwork.
What Is Bluebot?
First, Which “Cal Water” Do You Mean?
Two different things share the name. Mixing them up wastes an afternoon.
- Cal Water, the utility. California Water Service is a specific water company. Its own Cal Water conservation rebates cover lawn-to-garden conversions, high-efficiency toilets, clothes washers, smart irrigation controllers and sprinkler nozzles. Its published catalog does not list a flow monitoring device rebate.
- “Cal water rebates,” the search. Most people mean California water rebates in general. Regional agencies run those. Metropolitan runs SoCal Water$mart, the East Bay Municipal Utility District covers the East Bay, and retail utilities such as LADWP add their own funding on top.
For a smart water meter rebate, you want the second group.
Rebate Amounts at a Glance
As of August 2026, these are the published amounts for a flow monitor device rebate.
Program | Amount | Key condition |
|---|---|---|
SoCal Water$mart (Metropolitan) | $100 base incentive | Device must be on the Qualifying Products List; pilot program, funding limited |
LADWP (via SoCal Water$mart) | Up to $150 | Single-family customers; device monitors water on your property, not on the utility meter |
EBMUD Flowmeter Rebate | 50% of the device cost, up to $200 | Device must appear on EBMUD’s Qualifying Flowmeters List |
Metropolitan publishes a base incentive of $100 for qualifying flow monitor devices. LADWP raises that to up to $150 for its own customers, and lists it as a water flow/leak detection rebate. EBMUD works differently. It reimburses half the flowmeter cost, excluding taxes, shipping and installation. It caps the payment at $200 per device. Amounts vary by agency, change without notice, and depend on funding when your application is approved.
What You’ll Need Before You Start
- Your water agency’s name (it is on your bill)
- A recent water bill for the service address
- A device that appears on your agency’s qualifying list: check it before you buy
- An itemized sales receipt showing brand, model number, individual price and date of purchase
- For EBMUD, a dated photo of the finished installation
- Reliable Wi-Fi at the installation location and a smartphone or tablet, if you apply through SoCal Water$mart
How to Apply for a Cal Water Rebate, Step by Step
The rebate application process is broadly the same for both programs.
Step 1: Identify the agency that pays you
Rebates come from the agency that bills you for water, or from the wholesaler behind it. Southern California customers usually apply through SoCal Water$mart. East Bay customers apply directly to EBMUD. Residential property owners qualify. So do multi-family owners of one to four units under the SoCal Water$mart program.
Step 2: Check the qualifying products list first
People skip this step, and it costs them money. Only models on the SoCal Water$mart Qualifying Products List are eligible. The program tells buyers to check that list before purchasing. EBMUD publishes its own Qualifying Flowmeters List. That list was last updated in August 2024, and it includes Bluebot as an on-pipe device. The entry covers both Wi-Fi and LoRa network connections. EBMUD also states plainly that rebates are not guaranteed.
Step 3: Confirm the technical requirements
EBMUD sets four device rules. The meter must measure your account’s total water usage at least hourly. It must report that usage through a web portal or mobile app. It must send automatic leak alerts. And it must be designed for at least two years of continuous operation. It also must not interfere with the EBMUD meter. SoCal Water$mart adds its own conditions. Applicants must be single-family customers with reliable Wi-Fi at the installation location, plus a smart device such as a smartphone or tablet. LADWP adds one more rule: qualifying devices monitor water use on customer property, not on the utility meter.
Step 4: Buy and install the device
An on-pipe monitor straps to the outside of your pipe. It needs no plumbing work. Keep the itemized receipt: that is the version the agency asks for.
Step 5: File the application
SoCal Water$mart applications go through Metropolitan’s rebate website. You upload a recent water bill and your sales receipt. Rebates are paid only to the utility customer of record named on the bill. LADWP directs application questions to SoCal Water$mart at 1-888-376-3314. EBMUD applicants face a hard deadline. File within 90 days of purchase, with a dated receipt and a photo of the installation.
Step 6: Keep the device installed
EBMUD allows one flowmeter rebate per service address. The device must stay in place for at least two years. Remove it early and the district can claw the rebate back.
How a Bluebot Meter Earns the Rebate, Then Keeps Paying
The flow monitor incentive is the smaller half of the return. A flow monitor exists to catch the leak you would otherwise find on a bill. That is why agencies subsidize it.
The Bluebot smart water meter clamps onto the outside of your pipe. It tracks real-time flow, stores usage history, and sends leak and overuse alerts to the bluebot Water app and the FloDash(TM) dashboard. You can watch consumption 24/7 from a phone or a desktop. You can set budget alarms. And you can use historical data to tighten efficiency over time.
Two Bluebot models cover the two connectivity cases agencies care about. The 100-W (Bluebot Hero) is the Wi-Fi meter for 3/4 inch through 2 inch pipe. The 100-WAN (Bluebot ProLink) uses LoRaWAN wireless, so it suits meter locations with no usable Wi-Fi. Because it reports over LoRaWAN, the ProLink needs a Bluebot Gateway on site. The gateway is a separate purchase, and the rebate applies to the flowmeter, so check with your agency what it counts.
That distinction matters for eligibility. The SoCal Water$mart flow monitor rebate requires reliable Wi-Fi at the installation location, so the Wi-Fi model is the relevant one there. EBMUD’s list accepts the Bluebot meter on either Wi-Fi or LoRa. Either way, check your exact model against your agency’s current list before you buy. That is the program’s own instruction, not just ours.

Other California Water Rebates Worth Stacking
A flow monitor is rarely the only rebate you qualify for. LADWP’s residential program shows how much local top-ups matter.
Indoor. LADWP pays $250 per toilet. To qualify, you replace a fixture using 1.6 gallons per flush or more with one rated at 1.1 gpf or less. It also pays up to $500 for a high-efficiency clothes washer that meets the CEE Tier 1 standard. Metropolitan’s base amounts are lower: about $40 for a premium high-efficiency toilet, and $85 for a washer. That gap is why you check your own agency. The U.S. EPA’s WaterSense (2026) program reports that toilets account for nearly 30 percent of a home’s indoor water use. Replacing old models can save a family nearly 13,000 gallons and more than $170 a year.
Outdoor. The turf replacement rebate is the biggest single line item. Older guides still quote a range of between $1 and $3 per square foot. As of 2026, Metropolitan’s residential base rate is $2.00 per square foot, for up to 5,000 square feet a year. LADWP pays $5.00 per square foot, and it requires pre-approval before you start. LADWP also offers up to $200 per weather-based irrigation controller, up to $6 per rotating nozzle (15 minimum), up to $50 per rain barrel, and up to $500 for a cistern of at least 200 gallons.
Fixtures. Showering accounts for nearly 17 percent of residential indoor water use, according to WaterSense (2026). Standard showerheads run at 2.5 gallons per minute. WaterSense-labeled models use no more than 2.0 gpm. That saves an average family 2,700 gallons of water and more than 330 kilowatt hours of electricity a year. Faucet aerators work the same way.
Troubleshooting: Why Rebate Applications Get Rejected
Most rejections come from four avoidable mistakes.
- The device was not on the list. The published qualifying list decides eligibility, not how good the product is. Check the list on the day you buy.
- The receipt was incomplete. Agencies want brand, model number, individual price and date of purchase on one itemized document.
- The deadline passed. EBMUD’s 90-day window runs from the purchase date, not the installation date.
- The applicant was not the customer of record. The rebate goes to the person named on the water bill. That catches out landlords and recent movers.
One more mistake applies to landscaping. LADWP requires pre-approval on turf replacement. Tear the lawn out first and the rebate is gone.
Requirements and amounts vary by water agency and by funding year. Treat every figure here as a starting point, and verify it with the agency that bills you.
Frequently Asked Questions
Can I claim a Cal Water rebate from both SoCal Water$mart and EBMUD?
No. You apply to the agency that supplies your water, and a property is served by one water agency. EBMUD requires the flowmeter to be installed at an active EBMUD service location, while SoCal Water$mart pays customers of Metropolitan’s member agencies in Southern California. Check the agency name on your water bill, then apply to that program only.
Who can claim the rebate if I rent my home?
The rebate goes to the utility customer of record named on the water bill, so a tenant who pays that bill may be eligible while one who does not generally is not. LADWP states that rebates are available only to the customer of record. Renters should also get the owner’s permission first, because EBMUD requires the meter to stay in place for two years.
What happens if I buy a water meter that is not on the qualifying list?
You will not receive the rebate. Eligibility is decided by the published qualifying list, not by the quality of the device, and SoCal Water$mart tells buyers to check its Qualifying Products List before purchasing. EBMUD applies the same rule through its Qualifying Flowmeters List, and states that rebates are not guaranteed. Confirm the exact model on the day you buy.
Do I need Wi-Fi at the meter to qualify for the flow monitoring device rebate?
It depends on the program. SoCal Water$mart requires reliable Wi-Fi at the installation location plus a smartphone or tablet, so a Wi-Fi meter is the relevant choice there. EBMUD is broader: its Qualifying Flowmeters List, updated in August 2024, records Bluebot as an on-pipe device working over either Wi-Fi or a LoRa network. Verify your model against your own agency’s list.
How much of a smart water meter’s cost does the rebate actually cover?
Only part of it. Metropolitan publishes a base incentive of $100 through SoCal Water$mart (2026), and LADWP raises that to up to $150 for its customers. EBMUD instead reimburses 50 percent of the flowmeter cost, excluding taxes, shipping and installation, capped at $200 per device. Treat the rebate as an offset rather than full funding, and confirm the current amount before you buy.
Why do water agencies pay for leak detection devices at all?
Because undetected household leaks waste treated water the agency has already paid to supply. Both programs sit inside broader conservation efforts: EBMUD runs its flowmeter rebate through water conservation, and Metropolitan lists flow monitors alongside its toilet, turf and irrigation rebates. Funding is limited, and SoCal Water$mart describes its flow monitor rebate as a pilot program.
