What to do today

If you have a shutoff notice, the date on it is the one that matters. These steps work best in this order.

Call your utility before the date on your notice
Ask for a payment plan or a deferred payment arrangement. Most states require your utility to offer one, and asking before the date is what keeps your service on. The number is on your bill.
Apply for energy assistance
LIHEAP helps with utility bills and does not have to be paid back. Call the national referral line on 1-866-674-6327 weekdays 9am to 7pm Eastern, or visit energyhelp.us.
Dial 211 for local help
211 is free and connects you to local funds for utilities, rent and food. Some local agencies can pay a utility directly to stop a shutoff.
Ask about medical certification
Wyoming recognises medical protections. If anyone in your home has a serious illness or relies on powered medical equipment, a note from a doctor can delay a shutoff. Ask your utility for the form today, because it usually has to be back within days.
Contact the regulator if your utility will not work with you
psc.wyo.gov handles complaints against regulated utilities in Wyoming. Filing one can pause a disconnection while it is looked at.

Water Shutoff Rules

Regulatory notice requiredNot regulated / varies

Major Utilities

Cheyenne Board of Public Utilities

City of Cheyenne, Wyoming; municipal water and sewer utility operated by the city's Board of Public Utilities (BOPU)

15-day notice

BOPU is a city-owned utility, so it is outside Wyoming Public Service Commission jurisdiction and the investor-owned tariffs above do not bind it: Wyo

Stat. §37-1-101(a)(vi)(E) excludes from "public utility" any water facility "owned by a municipality," and §37-1-101(a)(vi)(H)(II) provides that "[n]one of the provisions of this chapter" - chapter 1 of Title 37, which carries the definitions and the Commission's grant of authority - apply "[t]o public utilities owned and operated by a municipality of the state of Wyoming," except as to service extended outside the corporate limits (fetched at https://www.wyoleg.gov/statutes/compress/title37.pdf)

The City of Cheyenne's own code governs instead

Cheyenne Municipal Code §13.04.180, "Disconnection for nonpayment," as codified (Ord

4416, §1, 2-28-22

2001 In-house code §44-21): if the consumer "fails to request a review within seven days of notice of a delinquent bill and notice of the opportunity for review, and if payment is not made within fifteen (15) days from the date of the notice, the water shall be shut off" and a late penalty under §13.04.170 "must be paid in full before water service is resumed." If a review is requested and delinquency is found, shutoff follows 5 days after that determination instead

The code adds that "[n]otice under this section is deemed received by the consumer within three days of mailing"

the 15 days is measured from the date of the notice, and no total is computed here

Confirmed current, not a proposal: the cited text is the codified section in Municode job 494452, Supplement 73, "Codified through (Covering Ordinances through 4662 passed March 23, 2026)," and Ord

4416 appears as the adopted source note on the section itself

Neither the reconnection fee nor the late-payment penalty amount is in the code - §13.04.140 and §13.04.170 leave both to be established by the BOPU and approved by the governing body - and BOPU's own rate schedule at cheyennebopu.org could not be read from this environment (the host returns a blanket Akamai HTTP 403, including for robots.txt), so reconnection_fee and assistance_programs are left null rather than guessed

Fetch note for re-verifiers: the reader-facing page for this section is https://library.municode.com/wy/cheyenne/codes/code_of_ordinances?nodeId=TIT13PUSE_CH13.04PUUTGE_13.04.180DINO, but it is a client-rendered app that returns a ~20-byte shell to a plain HTTP request, so source_url points instead at Municode's own content service, which returns the full section text to an ordinary fetch

Rebuild that URL if the supplement changes: api.municode.com/Clients/stateAbbr?stateAbbr=WY gives ClientID 1625, api.municode.com/Products/clientId/1625 gives ProductID 16266, and api.municode.com/Jobs/latest/16266 gives the current jobId
