Does a water shortage warning restrict roof cleaning?

The district's own record shows a warning cycle from start to finish. Its water shortage page, read on September 14, 2026, carries an item posted June 4, 2026: “The South Florida Water Management District rescinded the Water Shortage Warning issued on Feb. 5, 2026 for Lee and Collier Counties.”

The same item gives the reason. Since the wet season began on May 15, 2026, the Lower West Coast had received 4.46 inches of rain, over 140 percent of normal, and groundwater in the Lower Tamiami Aquifer had risen about three feet on average. A warning stood for four months, and then the district withdrew it.

What a warning is comes from the rule. Under 40E-21.231(3), before declaring a water shortage the district's Governing Board or Executive Director “may issue a water shortage warning calling for voluntary reductions in demand.” Voluntary is the working word. The phase restrictions in Chapter 40E-21, the ones that reach outside pressure cleaning, are written to apply when a phase “is declared by the District,” and a warning is not a declaration. The county's standing washing rule is quoted on the roof cleaning page, under its Florida water rules.

That record is dated, and the status moves. On the day it was read, the page showed no declaration for Collier, while an item posted May 4, 2026 described a Modified Phase II Water Shortage Order for a designated area of one city outside the four places this site names, limited to residents and businesses that use private wells in the Mid-Hawthorn Aquifer for irrigation. The current position is posted on the district's water shortage page.

Three instruments can come out of the district in a dry spell, and they do very different things to the water a roof wash uses.

The phase names, from Phase I Moderate to Phase IV Critical, and the reductions behind them are defined under water shortage phase. The body issuing all three instruments, and the counties it covers, is described under South Florida Water Management District.

Chapter 40E-21 does print a pressure cleaning line for each declared phase. The mistake is reading that line as the order.

Rule 40E-21.251 sets four phases by the estimated percent reduction in overall demand, and says the phase “determines the type of water use restrictions which will be ordered in a declared water shortage.” In each phase, the Other Outside Uses paragraph carries a line on pressure cleaning, running from “only low volume pressure cleaning, seven days a week” in the Phase I and II texts to Monday and Wednesday in Phase IV; the phase-by-phase list sits in the water shortage phase entry linked above.

Two things keep that day list from being a schedule. First, each phase's text applies “when” the phase is declared, so outside a declaration it is not an everyday rule; that is a reading of the rule's own wording, not a sentence it prints. Second, Rule 40E-21.271(2) says the Board “may order” the phase restrictions and “may order any combination in lieu of or in addition to” them of the further restrictions the rule lists, where needed to reach the reduction. The district's page shows orders it describes as Modified Phase IV and Modified Phase II. A declared phase does not automatically carry the phase text's day list; the order carries what the order says.

The rule also puts a duty on every water user: “It shall be the duty of each water user to stay informed as to the phase of water shortage and the applicable restrictions for that phase.” What the low-volume equipment in those lines means is taken up in what counts as low-volume pressure cleaning.

Outside a declaration, the rules a roof wash meets are local ones. During a declaration, the district's order is laid over them.

For a Collier address outside the cities, the standing rule is Ordinance 2015-27, whose county summary lets exterior home surfaces and roofs be washed “anytime”, given low-volume equipment or a self-canceling nozzle; the summary is silent on its reach within the cities. The Naples water calendar sets that rule beside the county's irrigation days through the year. How the local rules differ for Naples, Marco Island, Estero and Bonita Springs is set out in which water rules cover exterior cleaning in the four named places.

When the district declares a water shortage, its page says the declaration “supersedes the District's Year-Round Landscape Irrigation Rule and any local landscape watering ordinance for the duration of the declaration.” The terms that decide a roof wash during a declaration are the ones printed in that order, not the phase table on its own.
