In This City, Letting the Tap Run While Brushing Your Teeth Could Result in a Fine

A running faucet for two minutes during brushing your teeth is such a commonplace habit that we hardly question it anymore. And yet, in an American city, this almost universal reflex can today land you in real trouble with the municipality. Don’t panic, this isn’t a sci‑fi eco-dystopia, but a very concrete measure, passed in black and white, aimed precisely at these everyday actions we barely notice. It invites us to rethink our own habits, especially since drinking water is a resource more fragile than it seems. Off to California, where a city has decided to tackle the issue head‑on, even if it means disrupting some deeply ingrained routines.

An innocuous gesture becomes illegal in Santa Clara

In Santa Clara, California, brushing your teeth with the faucet running is no longer merely discouraged: it is prohibited by municipal regulation. News that is bound to surprise, given how this habit forms part of the automatisms of millions of households, in France as elsewhere. You turn on the faucet, grab your toothbrush, and water continues to flow while you work at the mirror, without really thinking about it.

But in Santa Clara, this behavior now falls into the category of unnecessary and avoidable uses of drinking water. The city has chosen to legislate on this exact point, considering that this waste, however minor it may seem at the level of a household, accumulates heavily when multiplied by thousands of residents. A choice that may seem harsh, but which fits into a broader logic of prudent water resource management, particularly sensitive in this region of the United States.

What exactly does the California municipal regulation say

The text adopted by the city does not settle for a vague slogan about saving water. It concretely lists behaviors considered wasteful and explicitly mentions faucets left running without any real use of water, especially during brushing teeth. This precision is not incidental: it shows that local authorities aimed to target a daily gesture identified as one of the most frequent and easiest to correct.

Other allegedly superfluous uses are also targeted by this regulation, such as excessive watering of green spaces or washing vehicles without a device capable of cutting the water between rinses. The stated objective is clear: to hold each resident accountable for a resource that is not inexhaustible, tackling both major consumptions and the small habits that, taken together, account for sizable volumes of water.

Cape Town, inadvertently a pioneer in the fight against water waste

Santa Clara does not invent the concept entirely. Before it, Cape Town, in South Africa, had already left a mark with a municipal regulation prohibiting wasteful or negligent use of drinking water. Cape Town faced an extremely severe water crisis, to the point that local authorities called it Day Zero, the day when municipal taps would simply stop flowing due to lack of reserves.

This extreme situation pushed the South African municipality to adopt particularly strict measures, ranging from per‑person water rationing to outright bans on certain uses deemed non-essential. Cape Town thus became a reference often cited in debates about urban water management, a model that other cities, including those beyond the Atlantic, watch closely to anticipate their own difficulties before they deteriorate into an open crisis.

Why the water crisis now pushes cities to legislate

If Santa Clara and Cape Town have taken the step of regulation, it is certainly not by accident. California has faced recurring drought episodes for several years, stressing groundwater and drinking water reservoirs. In this context, every liter saved counts, and local authorities seek concrete levers to reduce consumption without waiting for the situation to become critical.

Legislating on everyday gestures, no matter how trivial, sends a strong signal to the public: water is no longer a resource to be treated as guaranteed and unlimited. This kind of regulation fits into a broader approach of hydrological sobriety, where efforts aim to influence individual behaviors alongside investments in infrastructure, such as wastewater reuse or sea water desalination, particularly developed in California.

Sanctions, enforcement and residents’ reactions to this ban

Concretely, how does such a regulation apply in daily life? The cities that have enacted these prohibitions typically rely on a graduated system, combining awareness campaigns, warnings, and financial penalties in cases of recidivism or clear waste. The aim isn’t to turn every home into a potential suspect, but to have a legal framework that allows intervention against the most problematic behaviors, especially when waste becomes systematic.

On the part of residents, reactions are mixed. Some applaud a necessary awakening, arguing that these small adjustments do not demand an insurmountable daily effort. Others deem the measure excessive, or difficult to enforce in practice, as it seems hard to monitor what happens behind every bathroom door. Several simple actions can nonetheless bring one into compliance without upending one’s habits:

• Turn off the water while brushing teeth and reopen it only to rinse
• Install a water-saving aerator on the bathroom faucet
• Prefer a glass of water to rinse the mouth rather than a continuous jet
• Regularly check for leaks on taps and toilet flushes

Beyond the debate, this California regulation at least has the merit of bringing back to the forefront an essential topic: our relationship with drinking water, too often treated as an already available resource. Whether in Santa Clara, Cape Town, or elsewhere, the takeaway remains the same: saving water often begins with the simplest gestures, those we hardly notice.
