Central Iowa Stage 0: Commercial Irrigation Returns to Normal Schedule
CIWW returned Central Iowa to Stage 0 July 27. See which restrictions ended, the encouraged normal even/odd schedule, no-Monday lawn-watering guidance, and who owns the account and bill.
Direct answer
Central Iowa Water Works returned the region to Stage 0 on July 27, ending all mandatory and voluntary water-use restrictions. Businesses can return to the normal encouraged even/odd lawn-watering schedule—Sunday, Wednesday, and Friday for even addresses; Tuesday, Thursday, and Saturday for odd addresses; no lawn watering Monday—after checking any local-provider instruction and keeping ordinary conservation practices.

Return controllers to Stage 0 without dropping the normal schedule
CIWW ended all mandatory and voluntary restrictions July 27. The prior Stage III ban and Stage II 50% reduction no longer govern, while the encouraged normal schedule, conservation, efficient irrigation, and leak repair remain the operating frame.

Current official status
The July 27 decision returned Central Iowa to Stage 0
The Central Iowa Water Works Technical Committee met July 27 and voted to end all mandatory and voluntary water-use restrictions. CIWW returned the region to Stage 0 after the nitrate-removal facility went offline July 23, concluding 193 days of operation.
That same-day decision is the controlling current notice. Commercial teams should retire the earlier emergency instruction, verify any newer CIWW or local-provider notice, and record the source used for each controller change.
Normal Stage 0 schedule
Use even/odd lawn-watering days and keep Monday off
CIWW encourages the normal even/odd schedule: Sunday, Wednesday, and Friday for even-numbered addresses; Tuesday, Thursday, and Saturday for odd-numbered addresses; and no lawn watering Monday.
These are encouraged Stage 0 stewardship days, not a requirement to water on every assigned day. CIWW also asks customers to water only when needed, avoid peak heat, use efficient irrigation, repair leaks promptly, and continue everyday conservation.
Smart Valve operational analysis
Close the emergency work order before restoring controller schedules
For every site, record the service address, address parity, local provider, irrigation meter, controller, vendor work order, July 27 status change, and approving operator. Remove the old restriction from active instructions while preserving the dated record.
This change-control step is Smart Valve analysis, not a CIWW requirement. Its purpose is to prevent one regional update from becoming a blanket runtime increase across properties with different landscapes, providers, meters, or operating needs.
Accounts and bills
CIWW coordinates regional supply while member providers keep retail accounts
CIWW manages regional treatment and supply, while local utilities, rural providers, and city departments remain the contacts for accounts, bill payment, and customer service. Those providers can use different rates, fixed charges, sewer links, meter arrangements, and policies.
The three CIWW notices establish no common retail rate, penalty, rebate, credit, or savings model. A defensible bill analysis starts with the actual provider, account, meters, and bill after the operating schedule is confirmed.
Superseded history
Keep the prior Stage III ban and Stage II reduction as dated history
CIWW’s July 9 notice kept commercial and governmental irrigation prohibited under the prior Stage III ban. On July 20, CIWW moved all customer classifications to Stage II, allowing irrigation while asking for an approximately 50% lawn-watering reduction.
The July 27 Stage 0 decision superseded both emergency instructions. Keep the July 9 and July 20 sources in the operating record, but do not present the ban or 50% request as current.
Decision checklist
What to update after the return to Stage 0
- 1Confirm the service address, address parity, local provider, account, and any dedicated irrigation meter.
- 2Retire the prior ban or Stage II reduction from the active controller and vendor instruction.
- 3Use Sunday, Wednesday, and Friday as the normal encouraged days for even-numbered addresses.
- 4Use Tuesday, Thursday, and Saturday as the normal encouraged days for odd-numbered addresses.
- 5Keep Monday lawn watering off, water only when needed, and repair leaks promptly.
- 6Record the July 27 change and approving operator, then monitor CIWW and provider notices.
Scope boundary
Where Smart Valve realistically fits
The current official notice and local provider control the operating schedule. Smart Valve cannot change CIWW’s stage, authorize an unaddressed use, set a provider tariff, or turn encouraged stewardship into a mandate or guarantee.
After the Stage 0 schedule, provider, account, and meter arrangement are confirmed, Smart Valve can help a commercial team review actual metered consumption and provider-specific usage-linked exposure. Fixed charges, sewer treatment, credits, and other policies stay separate.

Frequently asked questions
What is the current Central Iowa water-use stage?
Central Iowa Water Works returned the region to Stage 0 on July 27, ending all mandatory and voluntary water-use restrictions. Check for any newer CIWW or local-provider notice before changing a controller.
What lawn-watering schedule applies at Stage 0?
CIWW encourages the normal schedule: Sunday, Wednesday, and Friday for even-numbered addresses; Tuesday, Thursday, and Saturday for odd-numbered addresses; and no lawn watering Monday. Water only when the landscape needs it.
Is the Stage II 50% lawn-watering reduction still active?
No. The approximately 50% request belonged to the July 20 Stage II notice and was superseded by the July 27 return to Stage 0. Keep it only as dated operating history.
Who handles the account, bill, and any property-specific savings analysis?
The local provider retains the account, bill, tariff, and customer service. Any property-specific analysis must use that provider’s actual bill, meters, fixed charges, sewer treatment, and operating facts.
