How the rule works

Sweetwater Authority assigns no watering days and no required watering hours: there is no odd or even address rule and no days-per-week cap in force. Its own page does encourage sprinklers no more than 3 days per week between 6:00 pm and 9:00 am, but that wording sits under Water Use Reduction Measures with the verb "are encouraged", so it is advice and carries no fine. What is enforceable now is a set of water waste prohibitions that the Authority says are currently in effect for all customers, including no runoff, no watering lawns within 48 hours of rain, and no hosing off hardscapes. Sweetwater serves only the western and central portions of Chula Vista, so eastern Chula Vista addresses are served by Otay Water District instead and are not covered by these rules. The Authority has been at Level 1 Drought Watch, the voluntary baseline level of its Drought Response Plan, since 2016.

How many minutes to run sprinklers on each water day

One zone at a time, from the state climate table for Chula Vista and the month you pick. The plan does every zone for every month.

Why rain covers it

October asks this zone for about 37 minutes of sprinkler time a week, from the state climate table for Chula Vista. That is less than one run, so the sheet shows none.

Established plantings live on the season's rain. New plantings still want a hand watering in a dry week.

Rules and fines in Chula Vista

Current stage Level 1 - Drought Watch (the baseline level of the Drought Response Plan, in effect since 2016 per the Authority's own Drought Updates page). Level 1 is defined as voluntary in Table 1 of the 2025 Water Shortage Contingency Plan, with customers requested to reduce use by up to 10 percent from the base.

The exceptions include new plantings, with conditions. The full text is below.

First: a written warning. Then $50, $100, $200 and $500 within one year.

Full text of the rules

Exceptions to the Chula Vista rules

  • New lawns: the sprinkler hours guidance does not apply 'for the first thirty (30) days necessary to establish a new lawn.' The public page prints this as a 30 day grace period for customers establishing new lawns.
  • Hardscape washing: Drought Response Plan Section 7(A)(1) permits hosing off sidewalks, driveways or other hardscapes '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.' The public Water Waste Prohibitions page prints a shorter version of the same carve out, 'except as necessary for immediate safety or sanitary hazards.'
  • Drip and hand watering: customers 'are encouraged to use drip methods or hand irrigation whenever possible and prudent to water landscaped areas, including trees and shrubs that are not irrigated by a landscape irrigation system.' These methods are encouraged rather than restricted.
  • Nozzle type carve out for the ten minute per station rule at Level 2 and Level 3 only: the cap 'does not apply to landscape irrigation systems using water efficient devices, including but not limited to weather-based controllers, drip/micro-irrigation systems and stream rotor sprinklers.' Level 4 measure 6 writes the same ten minute cap with no carve out at all, and the Level 4 preamble replaces conflicting lower level language, so a Level 4 declaration would remove this carve out.
  • Alternate water sources: 'The provisions of this Drought Response Plan do not apply to use of water from private wells or other approved alternate water sources including, but not limited to grey water and rain water catchment systems.'
  • Pools, ornamental lakes and ponds: at Level 2, customers 'are encouraged to stop filling or re-filling pools, ornamental lakes and/or ponds, except to the extent needed to sustain aquatic life.' At Level 3 the same measure adds a qualifier: 'except to the extent needed to sustain aquatic life, provided that such animals are of significant value and have been actively managed within the water feature prior to declaration of a drought response level under this ordinance.'
  • Vehicle washing: allowed with a hose equipped with an automatic shut-off nozzle. At Level 4 customers 'shall stop hand-washing vehicles' and are encouraged to stop washing vehicles 'except at commercial carwashes that re-circulate (reclaim) water onsite, or by high pressure/low volume wash systems.'
  • Level 5 and Level 6 carve outs from the total irrigation stop: crops and landscape products of commercial growers and nurseries; existing landscaping necessary for fire protection as specified by the fire marshal of the local fire protection agency; existing landscaping for erosion control; plant materials identified as rare or essential to the well-being of rare animals; landscaping within active public parks and playing fields, day care centers, school grounds, cemeteries and golf course greens, provided such irrigation 'does not exceed two (2) days per week'; watering of livestock; public works projects and actively irrigated environmental mitigation projects.
  • Penalty exemptions at Levels 2 through 4 (not day rules): residential water use at or below 28 HCF in the bi-monthly billing periods for bills received in July, August, September and October and 22 HCF for all other months during Level 2; at or below 17 HCF bi-monthly during Level 3; at or below 11 HCF bi-monthly during Level 4; accounts related to a medical nature; and commercial establishments offering services that allow individuals alternative means for completing water dependent tasks.
  • Appeals: a Target Water Allocation appeal may be filed at any time, and a penalty appeal within two (2) weeks of receipt of the bi-monthly or monthly bill, in writing on the appeal form filed with the General Manager or designee, with a further written appeal to the Governing Board within seven (7) days of receipt of the written decision.
  • Sweetwater Authority publishes no exception for hot days, heat waves, edible or vegetable gardens, potted plants, or smart controller enrollment.

  3. 3Third violation of any prohibition within one (1) year: $100
  4. 4Fourth violation of any prohibition within one (1) year: $200
  5. 5Each violation thereafter of any prohibition within one (1) year: $500
  6. 6Any violation occurring more than one (1) year from the previous one is treated as a first violation
  7. 7Each day that a violation of a prohibited water conservation measure occurs is a separate offense
  8. 8Separate ladder for exceeding a Target Water Allocation, which applies only at Level 2 and above: first and second allocation overage violation written warning; third within one year $100; fourth within one year $200; each thereafter within one year $500. Customers are notified of an overage and given one (1) full billing cycle to bring usage below the allocation.
  9. 9If the Governing Board activates mandatory water use reductions by resolution, a willful violation 'may be prosecuted as a misdemeanor punishable by imprisonment in the county jail for not more than thirty (30) days or by a fine not exceeding one thousand dollars ($1,000 -U.S.A. currency), or by both, as provided in California Water Code Section 377'
  10. 10Willful violations of mandatory conservation measures may also be enforced by discontinuing service to the property at which the violation occurs, as provided by California Water Code Section 356 et seq.
  11. 11Rates and Rules effective 01/01/2026, Section 15.5, separately allows the Governing Board acting through its General Manager 'to apply such penalties as may be provided by law, or to take any other action as deemed appropriate, including but not limited to, the discontinuance of potable water service.'
  12. 12At the current Level 1 condition, the fine ladder reaches the state water waste prohibitions. Section 9 of the Drought Response Plan opens 'Any customer who violates a state water waste prohibition at any time, and/or uses, causes to be used, or permits the use of water in violation of this Drought Response Plan during a Level 2 ... condition ... is guilty of an offense punishable as provided.' The advisory three days per week and 6:00 pm to 9:00 am guidance carries no fine.

Chula Vista watering questions

What days can I water in Chula Vista?

Any day. Sweetwater Authority assigns no watering days, no odd or even address rule and no days-per-week cap at its current Level 1 Drought Watch condition. Mandatory day limits exist only at higher levels that have not been declared: no more than two (2) days per week at Level 2 and Level 3, and no more than 1 day per week at Level 4.

What hours can I run sprinklers?

There is no required time-of-day window right now. The Drought Response Plan asks Level 1 customers to limit sprinkler operation to the hours of 6:00 p.m. to 9:00 a.m. the following morning, but that measure reads "are encouraged to", so it is guidance rather than a rule. A mandatory window first appears at Level 2 Drought Alert, which is not in effect.

Is the 3 days a week limit an actual rule?

No, it is a recommendation. Sweetwater's Water Waste Prohibitions page prints it under Water Use Reduction Measures as "Customers are encouraged to restrict landscape irrigation with sprinklers to no more than 3 days per week between the hours of 6:00 pm and 9:00 am." The 2025 Water Shortage Contingency Plan marks Level 1 as voluntary and its enforcement table lists no Level 1 row for days or hours at all.

What is actually banned right now?

The Water Waste Prohibitions page states these are currently in effect for all customers. Banned: watering lawns in a manner that causes runoff, watering lawns within 48 hours of rain, using potable water to irrigate turf on public street medians, hosing off sidewalks, driveways or other hardscapes except as necessary for immediate safety or sanitary hazards, running fountains or decorative water features that are not connected to a recirculating system, and washing automobiles with hoses not equipped with an automatic shut-off nozzle. Major leaks must be repaired immediately and minor leaks within 24 hours of discovery. Non-functional lawns in commercial, industrial and institutional areas cannot be watered either, and that expressly includes common areas of homeowners' associations (HOAs).

What is exempt from the rules?

New lawns get a 30-day grace period from the sprinkler hours guidance, covering "the first thirty (30) days necessary to establish a new lawn." Hosing hardscapes is permitted 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. The Drought Response Plan also does not apply to water from private wells or other approved alternate water sources, including grey water and rain water catchment systems. Sweetwater publishes no exception for hot days, heat waves, edible or vegetable gardens, potted plants or smart controllers.

What is the fine for breaking the watering rules?

A first violation of any prohibition brings a written warning. A second violation within one (1) year is $50, a third within one year is $100, a fourth is $200, and each violation thereafter within one year is $500. Any violation occurring more than one year from the previous one is treated as a first violation, and each day that a violation occurs counts as a separate offense. The encouraged 3 days per week and 6:00 pm to 9:00 am guidance carries no fine.

Can I water after it rains?

No. Watering lawns within 48 hours of rain is one of the water waste prohibitions the Authority lists as currently in effect for all customers. It sits in the prohibitions block rather than the encouraged measures, so unlike the 3 days per week suggestion it is enforceable and applies year round.

My address is in Chula Vista but my bill is not from Sweetwater Authority. Why?

Sweetwater Authority covers only the western and central portions of Chula Vista, along with National City, Bonita Valley and Lincoln Acres in unincorporated San Diego County. Eastern Chula Vista addresses and part of Bonita are served by Otay Water District instead, and Sweetwater's own 2025 Urban Water Management Plan names Otay as bordering it on the east and south, the City of San Diego on the north and south, and California American Water on the south. The San Diego County Water Authority is the regional wholesaler rather than a retail supplier and sets no household watering days. Check the supplier named on your water bill.

How do I report water waste in Chula Vista?

Use the online Report Water Waste form at https://www.sweetwater.org/FormCenter/For-Customers-7/Report-Water-Waste-60, or call Sweetwater Authority at (619) 420-1413. For questions about your own water use rather than a neighbor's, the separate Water Efficiency Helpline is (619) 409-6779.
