Riverside Watering Schedule

Recommended patternRules verified August 28, 2026

Any day is allowed. These rules apply year round

  • No assigned days and no days-per-week cap. Stage One has been the declared stage since June 28, 2016, and RMC 14.22.020(C) makes its measures voluntary.
  • Directed practice, not a citable clock rule: RMC 14.22.030(B)(1) says non-agricultural irrigation should be done from 6:00 p.m. to 10:00 a.m.
  • Enforced at all times: no outdoor watering during and within 48 hours after measurable rainfall (RMC 14.22.010(B)(5)).
  • Enforced at all times: irrigation water cannot leave the landscaped area, and no hosing down driveways or sidewalks.
  • Enforced at all times: a vehicle wash hose needs a shut-off nozzle, and decorative fountains must recirculate.
  • No per-station minute limits today. The 15-minute spray and 30-minute rotor caps were struck by Ordinance No. 7556 in 2021.

Riverside has no mandatory watering days. Riverside Public Utilities customers are at Stage One, Normal Water Supply, reinstated by a City Council resolution adopted June 28, 2016 and never repealed, and RMC 14.22.020(C) states that Stage One conservation measures are voluntary and will be encouraged through public outreach, education, and awareness measures by the City. That is why the Stage One line in RMC 14.22.030(B)(1), "Non-agricultural irrigation should be done from 6:00 p.m. to 10:00 a.m.", is a directed practice and not a citable clock restriction; the city's 2025 Water Shortage Contingency Plan marks that same line "No" in its "Penalty, Charge, or Other Enforcement?" column. What does carry a citation at every stage is the water waste list in RMC 14.22.010: runoff off the landscaped area, hosing down driveways and sidewalks, a car wash hose with no shut-off nozzle, and watering during and within 48 hours after measurable rainfall. The three-times-per-week figure that circulated in 2022 came from a state emergency regulation the Governor rescinded on March 24, 2023, so it is history and not a current limit.

How many minutes on each watering day

Riverside Public Utilities assigns no watering days, so nobody can tell you how many days to split the week across. Set the days you actually water and this works out the minutes from Riverside's climate for the month you pick.

Climate data

Riverside · 59.4 in/yr

About 39 minutes per watering day, 2 days a week.

How that was worked out

Week's climate demand: 8.1 in for July × 7 ÷ 31 days = 1.829 in

Plants need: 1.829 × 0.8 = 1.463 in this week

Run time: 1.463 ÷ (1.6 in/hr × 0.7) × 60 = 78 min per week

Split: 78 ÷ 2 watering days = 39 min each time

If water runs off the edges before the cycle ends, split each day into shorter back-to-back cycles with a soak break between them. The total minutes stay the same.

Rain is not subtracted here. Skip watering during and after rain, and follow your supplier's rain rule. Point-source drip emitters and Bubblers are not in the list above: no manufacturer publishes an inches-per-hour rate for them, so those zones are watered by volume rather than by a run time against a rate.

Current status

Stage One, Normal Water Supply (Riverside Municipal Code 14.22.030). Stage One was reinstated by a City Council resolution adopted June 28, 2016 under Legistar file 16-1919, titled "A Resolution of the City Council of the City of Riverside, California, reinstating Stage One of the City's Water Conservation Program as set forth in Riverside Municipal Code Chapter 14.22 and repealing Resolution No. 22983." That declaration has NOT been repealed. A search of the City Council record through August 28, 2026 turns up no later resolution declaring a different water conservation stage, so Stage One is the stage in force today and its provisions, including the 6:00 p.m. to 10:00 a.m. irrigation window in RMC 14.22.030(B)(1), are live. Under RMC 14.22.020(C) and Table 6.14.040A of the Code, Stage One measures are voluntary and promoted through outreach, while the water waste prohibitions in RMC 14.22.010 are in force at all times regardless of stage and can draw a citation.

The schedule

Year round, Stage One (Normal Water Supply), the declared stage

No date range is printed in RMC 14.22.030. Stage One applies for as long as it remains the declared stage, which it has been since the resolution adopted June 28, 2016.

Days: No day assignment and no days per week cap. RMC 14.22.030(B) contains only two measures and neither limits watering days. RMC 14.22.020(C), as printed: "Stage one conservation measures are voluntary, and will be encouraged through public outreach, education, and awareness measures by the City." Table 6.14.040A of the Code labels Stage 1 as "Normal Conditions" with "Voluntary Conservation Measures" and "Standard" enforcement.

Hours: RMC 14.22.030(B)(1), in force under the Stage One declaration, as printed: "Non-agricultural irrigation should be done from 6:00 p.m. to 10:00 a.m. Irrigation water cannot leave the landscaped area." The window is live, and the operative verb is "should", so under the current stage it functions as a directed practice rather than a citable clock restriction. The runoff half of that sentence is separately backed at all times by RMC 14.22.010(B)(1), which prohibits applying potable water to outdoor landscapes in a manner that causes runoff onto adjacent property, non-irrigated areas, walkways, roadways, parking lots or structures. RMC 14.22.030(B)(2) permits graywater and recycled water irrigation on any day and at any time, subject only to City permits.

Run-time limits: None in the current text. Per-station run time caps of 15 minutes for pop-up spray sprinklers and 30 minutes for impact and rotor sprinklers used to sit in RMC 14.22.030(B)(1), and were struck out by Ordinance No. 7556 in 2021. They do not appear in the codified chapter (Supp. No. 33). No minute limits appear anywhere else in Chapter 14.22 either; the old Stage Three sprinkler run time clause now reads "[Reserved.]".

Summer, RPU and City customer guidance only, carries no ordinance force

No dates are printed. The City page says only "In summer".

Days: City press page "Three Ways To Be Waterwise & Save", published 05/01/2019: "In summer, water 3 days a week and 4 days when it is really hot." RPU's current Water Efficiency page instead states: "Many established landscapes and lawns need to be watered one or two times per week. Newer plantings, vegetables, and potted plants may need more frequent watering." Neither number is a mandatory limit and neither is set by ordinance or resolution.

Hours: Same 2019 City page: "water your lawn between 6:00 p.m. and 10:00 a.m. and never in the heat of the day." RPU's Water Efficiency page: "Water early in the morning (before 10a.m.) or later in the evening (after 6 p.m.)". This matches the Stage One window in RMC 14.22.030(B)(1).

Run-time limits: No per-station limit is set. The Water Efficiency page suggests cycle and soak instead: "instead of watering for 20 consecutive minutes, run sprinklers in four 5-minute sessions."

Winter, RPU and City customer guidance only, carries no ordinance force

No dates are printed. The City page says only "In winter".

Days: City press page "Three Ways To Be Waterwise & Save", published 05/01/2019: "In winter, water twice a week for a healthy, green lawn." Guidance only, not a mandatory limit.

Hours: Same as summer: between 6:00 p.m. and 10:00 a.m., matching RMC 14.22.030(B)(1).

Run-time limits: No per-station limit is set.

Exceptions and standing rules

  • Graywater and recycled water: RMC 14.22.030(B)(2) permits irrigation with graywater, as defined in the California Health and Safety Code, and with recycled water on any day and at any time, subject only to permits issued by the City.
  • Health, safety and permits: the water waste prohibitions in RMC 14.22.010(B) do not apply "where necessary to address an immediate health and safety need or to comply with a term or condition in a permit issued by a state or federal agency."
  • Vehicle washing with a hose is allowed if the hose has a shut-off nozzle or device that stops the flow immediately when not in use (RMC 14.22.010(B)(2)).
  • Fountains and decorative water features are allowed where the water is part of a recirculating system (RMC 14.22.010(B)(4)).
  • Splash pads: RMC 14.22.010(D) states a splash pad is a recreational feature and its operation is not prohibited as an unreasonable use of water.
  • Drip and microspray: there is NO longer an exemption for drip or microspray irrigated landscape in Stage One. That exemption existed before 2021 and was struck by Ordinance No. 7556. Since Stage One measures are voluntary anyway, nothing turns on it today, but the exemption should not be quoted as current text.
  • Agricultural irrigation: the Stage One hours guidance is written for "non-agricultural irrigation", so agricultural irrigation sits outside it.
  • Trees: RPU's Drought Status page encourages tree watering, with "Newly planted trees (less than two years old) will need five gallons of water, once a week.", "Young trees (less than three years old) ... require a deep watering of ten gallons, once every two weeks under the dripline.", and mature trees needing "deep watering ... when the top six inches of soil around your mature tree has dried out or once per month."
  • Nonfunctional turf under state law AB 1572: RPU's own AB 1572 page states single-family homes are exempt, including homes inside a homeowners association, because front and back yards attached to a single-family home are not association common areas. The state prohibition also does not bar water needed to keep trees and other perennial non-turf plantings alive, or water needed for an immediate health and safety need.
  • Rain: outdoor watering during and within 48 hours after measurable rainfall is prohibited at all times under RMC 14.22.010(B)(5). This is one of the few outdoor timing rules that is enforceable while Stage One is the declared stage.

Fines and enforcement

  1. Route: RMC 14.22.080(A) states that any violation of the water conservation article may be enforced by an administrative citation issued under Chapter 1.17 of the Code, and that "Prior to issuance of an administrative citation, the City shall give one courtesy notice requesting voluntary correction of the violation."
  2. Citation amounts, RMC 1.17.230(A) (amended by Ordinance No. 7767, 2026): $100.00 for the first occurrence, $500.00 for the second occurrence of the same type of violation, and $1,000.00 for the third and each subsequent occurrence of the same type of violation, unless the City Council sets a different amount by resolution. Fines are payable within 30 calendar days.
  3. RMC 1.17.231 does NOT apply to water rules. It sets a flat $500.00 fine for five specific fire code violations only (overcrowding, illegal burning, open flame, fire protection system without a permit, high piled storage).
  4. Each day counts separately: RMC 1.17.080 provides that each day a violation continues is a new, separate and distinct violation.
  5. Administrative civil penalties are a separate remedy from citations. RMC 1.17.300(D) caps them at $1,000.00 per day, per violation, and at $100,000.00 per parcel plus interest. RMC 1.17.320 is the section that governs how the daily amount is determined and when it starts to accrue, using nine listed factors such as duration, seriousness, history and good faith effort. RMC 1.17.320 itself names no dollar figure, so it is the right citation for how a civil penalty is set but the wrong citation for the dollar cap, which is in RMC 1.17.300(D).
  6. Criminal route, RMC 1.01.110: a Code violation is a misdemeanor unless declared an infraction, and the City Attorney may charge a misdemeanor as an infraction. Infraction: fine not exceeding $250.00. Misdemeanor: fine not more than $1,000.00, or up to six months in County jail, or both. Each day is a separate offense.
  7. RPU Water Rule 15 (Water Waste), effective May 18, 1995: a person wasting water pays the City for all such water at Water Rate Schedule WA-1 rates even though it is not metered, and after written notice the Director may shut off the water supply to the premises.
  8. Practical effect today: because Stage One measures are voluntary under RMC 14.22.020(C), a citation for outdoor watering in Riverside right now would rest on the always-on prohibitions in RMC 14.22.010 such as runoff, hosing driveways and sidewalks, no shut-off nozzle, or watering within 48 hours of rain, and not on the 6:00 p.m. to 10:00 a.m. window. The 2025 Water Shortage Contingency Plan makes this explicit: in its Demand Reduction Actions table the "Penalty, Charge, or Other Enforcement?" column reads "Yes" for every prohibited water waste item and "No" for the two Stage One (Shortage Level 1) items, including the 6:00 p.m. to 10:00 a.m. line.

Report water waste: Water waste is reported to the City through 311. RPU's Drought Status page directs anyone who spots water runoff or other water waste to report it through the 311 mobile app or the online form, and directs reporters to give the exact address and describe the water waste. The online form is at RiversideCA.gov/311. Code Enforcement, working with RPU, issues a courtesy notice first, as RMC 14.22.080(A) requires, before any citation. For nonfunctional turf questions under AB 1572, RPU's turf replacement page lists its Programs and Services team at (951) 826-5485.

Is this your water supplier?

RPU is the retail water utility for the City of Riverside and has served the city since 1913, drawing mainly on local groundwater under the Western-San Bernardino Judgment. Addresses outside the RPU service area are not covered by RMC Chapter 14.22 and follow their own supplier's rules. The 2025 Water Shortage Contingency Plan documents connections to neighboring systems: an emergency intertie with the City of Colton, a distribution system connection to the City of Corona, a two-way emergency connection with the City of San Bernardino, a connection to East Valley Water District near Pedley, an emergency and wholesale intertie with the City of Norco on Arlington Avenue, and several connections with Western Municipal Water District (Green Orchard, Fair Isle at Box Springs, the Mills imported water connection, Praed and Lake Hills, and Van Buren at Mockingbird). RPU also takes imported water through Western Municipal Water District and produces wholesale water for Norco and Western Municipal Water District. Anyone near a city boundary should confirm which utility bills their meter before applying these rules.

Questions people ask

What days can I water in Riverside right now?
There are no mandatory watering days. Riverside is at Stage One, Normal Water Supply, and RMC 14.22.020(C) reads: "Stage one conservation measures are voluntary, and will be encouraged through public outreach, education, and awareness measures by the City." Table 6.14.040A of the Code labels Stage 1 as "Normal Conditions" with "Voluntary Conservation Measures" and "Standard" enforcement, so no day assignment and no days-per-week cap applies to a household address. The city's own advice is split on frequency: a 2019 city press page says "In summer, water 3 days a week and 4 days when it is really hot" and "In winter, water twice a week for a healthy, green lawn", while RPU's current Water Efficiency page says "Many established landscapes and lawns need to be watered one or two times per week." Neither number is set by ordinance or resolution.
What hours should sprinklers run in Riverside?
RMC 14.22.030(B)(1) reads: "Non-agricultural irrigation should be done from 6:00 p.m. to 10:00 a.m. Irrigation water cannot leave the landscaped area." That window is live, because Stage One is the declared stage, but the operative verb is "should", so it works as a directed practice rather than a citable clock restriction. The 2025 Water Shortage Contingency Plan, adopted June 23, 2026, marks the 6:00 p.m. to 10:00 a.m. line "No" in its "Penalty, Charge, or Other Enforcement?" column while marking every water waste prohibition "Yes". The second half of that same sentence is different: runoff is prohibited at all times under RMC 14.22.010(B)(1). RPU's Water Efficiency page gives the same timing as advice, "Water early in the morning (before 10a.m.) or later in the evening (after 6 p.m.)", and suggests cycle and soak, "instead of watering for 20 consecutive minutes, run sprinklers in four 5-minute sessions."
Can I water after it rains?
No. Outdoor watering during and within 48 hours after measurable rainfall is prohibited at all times under RMC 14.22.010(B)(5). This is one of the few outdoor timing rules that is enforceable while Stage One is the declared stage, so it can draw a citation even though the evening watering window cannot.
What is banned year round in Riverside, and what is exempt?
The prohibitions in RMC 14.22.010 are in force at all times, whatever the stage, and those are the ones behind a Riverside water citation today. They cover applying potable water to outdoor landscapes in a manner that causes runoff onto adjacent property, non-irrigated areas, walkways, roadways, parking lots or structures; hosing down driveways and sidewalks; washing a vehicle with a hose that has no shut-off nozzle; running a decorative fountain that does not recirculate; watering during and within 48 hours after measurable rainfall; irrigating ornamental turf on public street medians; serving drinking water other than on request; and a separate rule for newly constructed landscape. The carve-outs are narrow: RMC 14.22.010(B) does not apply "where necessary to address an immediate health and safety need or to comply with a term or condition in a permit issued by a state or federal agency"; vehicle washing is allowed if the hose has a shut-off nozzle or device that stops the flow immediately when not in use (RMC 14.22.010(B)(2)); fountains and decorative water features are allowed where the water is part of a recirculating system (RMC 14.22.010(B)(4)); and RMC 14.22.010(D) states that a splash pad is a recreational feature and its operation is not prohibited as an unreasonable use of water. RMC 14.22.030(B)(2) permits irrigation with graywater, as defined in the California Health and Safety Code, and with recycled water on any day and at any time, subject only to permits issued by the City. The Stage One hours line is written for "non-agricultural irrigation", so agricultural irrigation sits outside it, and RPU's own AB 1572 page states that single-family homes are exempt from the state nonfunctional turf prohibition, including homes inside a homeowners association. One carve-out is gone: drip and microspray irrigated landscape was exempt from Stage One before 2021, and Ordinance No. 7556 struck that language, so it should not be quoted as current text.
What are the fines for wasting water in Riverside?
A courtesy notice comes first. RMC 14.22.080(A) states that a violation of the water conservation article may be enforced by an administrative citation issued under Chapter 1.17, and that "Prior to issuance of an administrative citation, the City shall give one courtesy notice requesting voluntary correction of the violation." The citation amounts in RMC 1.17.230(A), as amended by Ordinance No. 7767 in 2026, are $100.00 for the first occurrence, $500.00 for the second occurrence of the same type of violation, and $1,000.00 for the third and each subsequent occurrence of the same type, payable within 30 calendar days. Each day a violation continues is a new, separate and distinct violation under RMC 1.17.080. Two separate routes sit behind that: administrative civil penalties are capped by RMC 1.17.300(D) at $1,000.00 per day per violation and $100,000.00 per parcel plus interest, and under RMC 1.01.110 a Code violation charged as an infraction carries a fine not exceeding $250.00 while a misdemeanor carries a fine of not more than $1,000.00, up to six months in County jail, or both. RPU Water Rule 15, effective May 18, 1995, adds that a person wasting water pays the City for all such water at Water Rate Schedule WA-1 rates even though it is not metered, and after written notice the Director may shut off the water supply to the premises. Because Stage One measures are voluntary, a citation would rest on the RMC 14.22.010 list, not on the 6:00 p.m. to 10:00 a.m. window.
Do the old 15-minute sprinkler limit and the three-days-a-week rule still apply?
Neither one is current. Per-station run time caps of 15 minutes for pop-up spray sprinklers and 30 minutes for impact and rotor sprinklers used to sit in RMC 14.22.030(B)(1), and Ordinance No. 7556 struck them in 2021; no minute limits appear anywhere else in Chapter 14.22, and the old Stage Three sprinkler run time clause now reads "[Reserved.]". The three-times-per-week figure comes from July 2022, when the Council directed implementation of the Level 2 demand reduction actions in the Water Shortage Contingency Plan to meet a State Water Resources Control Board emergency regulation. The staff memo for that item said the Council was not being asked to declare a water shortage emergency, and no resolution declaring Stage Two was adopted. The Governor rescinded the state demand reduction requirement on March 24, 2023, so a page still showing a three-day cap for Riverside is quoting drought-era material.
What would change if Riverside declared Stage Two or a higher stage?
Each higher stage needs a City Council resolution first, and none has been adopted since Stage One was reinstated on June 28, 2016. Stage Two (RMC 14.22.040) would make all Stage One measures mandatory, restrict irrigation to 6:00 p.m. to 10:00 a.m. with irrigation prohibited any day from 10:00 a.m. to 6:00 p.m., and cap watering at three times per week. Stage Three (RMC 14.22.050) would cap watering at three times per week from April through October and two times per week from November through March. Stage Four (RMC 14.22.060) would allow only trees and shrubs, with odd addresses on Saturdays and even addresses on Sundays, 8:00 p.m. to 8:00 a.m. Treat all of that as standby text, not as the schedule for a Riverside address today.
Is Riverside Public Utilities my water supplier?
RPU is the retail water utility for the City of Riverside and has served the city since 1913, drawing mainly on local groundwater under the Western-San Bernardino Judgment. Addresses outside the RPU service area are not covered by RMC Chapter 14.22 and follow their own supplier's rules. The 2025 Water Shortage Contingency Plan documents connections to neighboring systems: an emergency intertie with the City of Colton, a distribution system connection to the City of Corona, a two-way emergency connection with the City of San Bernardino, a connection to East Valley Water District near Pedley, an emergency and wholesale intertie with the City of Norco on Arlington Avenue, and several connections with Western Municipal Water District at Green Orchard, Fair Isle at Box Springs, the Mills imported water connection, Praed and Lake Hills, and Van Buren at Mockingbird. Those are pipes between systems rather than service area lines, so anyone near a city boundary should confirm which utility bills their meter before applying these rules.
How do I report water waste in Riverside?
Water waste is reported to the City through 311. RPU's Drought Status page directs anyone who spots water runoff or other water waste to report it through the 311 mobile app or the online form at RiversideCA.gov/311, and asks reporters to give the exact address and describe the water waste. Code Enforcement, working with RPU, issues a courtesy notice first, as RMC 14.22.080(A) requires, before any citation. For nonfunctional turf questions under AB 1572, RPU's Programs and Services team can be reached at (951) 826-5485.
