Water Safety and Drinking Water at Work

Clean drinking water is one of the most basic things a workplace can offer, and one of the easiest to overlook. As summer heats up, it matters more than ever. This guide walks you through what the rules generally expect, how to look after taps, fountains and coolers, and how to build simple habits that keep your team safe and hydrated.

Key takeaways

In the UK, Workplace Regulations require wholesome drinking water for workers. In the US, OSHA sanitation rules require potable water.
Water needs to be easy to reach, clearly marked if there is any doubt, and served in a hygienic way.
Fountains, coolers, filters and little-used taps need regular cleaning and checks, not just installation.
Hot weather raises the stakes, so plan for more breaks and easier access to water through the summer.

Most small business owners never think about workplace water until something goes wrong: the cooler runs dry, a fountain looks grimy, a staff member feels faint on a hot shift, or a customer asks whether the tap in the back is safe to drink. None of these are dramatic on their own, but together they shape how safe and cared for your team feels.

The fix is not complicated. You need a reliable supply, a simple cleaning routine, clear signs and a plan for hot days. This guide covers all four, with a template you can copy and a checklist you can work through in an afternoon.

A quick note: this is general information, not legal or health and safety advice. Rules vary by country, state and type of business, and they can change. Check the official guidance where you are and talk to a qualified health and safety adviser if you are unsure.

What the rules generally expect

Most countries treat drinking water as a basic welfare requirement for workers. The details differ, but the idea is the same everywhere: people at work should be able to drink clean, safe water when they need it.

UK. The Workplace (Health, Safety and Welfare) Regulations require employers to provide an adequate supply of wholesome drinking water for workers. The Health and Safety Executive publishes guidance on how to meet this, including how water should be provided and labeled.
US. OSHA sanitation rules require employers to provide potable water for drinking and other uses. Some industries, such as construction and agriculture, have their own specific rules, and some states add more.
Elsewhere in Europe. Workplace welfare rules usually include access to drinking water. Check your national labor inspectorate or health and safety authority.

Beyond the rules, both the US and the UK have broad general duties for employers. In the US, OSHA's general duty clause covers recognized serious hazards. In the UK, the Health and Safety at Work Act sets a general duty, and employers with 5 or more employees must have a written health and safety policy and a written risk assessment. Water access and heat should be part of that thinking where relevant.

Choosing how to provide drinking water

There is no single right setup. The best option depends on your building, your team size and how people work. Here are the common choices.

Mains taps

A tap connected to the public mains supply is usually the simplest and cheapest option. Make sure it is in a clean place, such as a kitchen or break area, and not in a toilet or near cleaning chemicals. If a tap is not safe to drink from, label it clearly.

Drinking fountains

Fountains are handy for busy teams and avoid the need for cups. They need regular cleaning, because the spout and basin are touched and splashed often.

Water coolers and dispensers

Bottled coolers and plumbed dispensers work well where taps are hard to reach. They need a cleaning schedule, careful bottle storage and someone responsible for reordering. If you lease a cooler, check what servicing the supplier includes.

Bottled water for mobile teams

If staff work on the road, at events or on customer sites, provide water they can carry, such as refillable bottles and a supply in vehicles. Do not assume a customer's site will have water available.

Pro tip

Give every team member a refillable bottle with your logo on it. It cuts down on disposable cups, makes it easy to drink through a shift and doubles as a small welcome gift for new starters.

Keeping your water supply safe

Installing a fountain or cooler is the easy part. Keeping it clean is what actually protects people. Build a simple routine and give it an owner.

List every water point. Walk the building and note every tap, fountain, cooler, filter jug and ice machine that people drink from.
Assign an owner. One named person checks each point on a set schedule and reports problems.
Clean on a schedule. Wipe spouts, nozzles, drip trays and buttons often. Follow the manufacturer's instructions for deeper cleaning and sanitizing.
Replace filters on time. Filters that are past their date can do more harm than good. Note the replacement date on a label or in your log.
Run little-used outlets. Water that sits in pipes for a long time can become a problem. Flush taps that are rarely used, especially after a shutdown or holiday period.
Store bottles properly. Keep spare cooler bottles out of direct sunlight, off the floor and away from chemicals.
Log it. Record what was done, when and by whom.

Legionella and water systems

In some buildings, especially those with hot water tanks, cooling towers, showers or complex pipework, there is a risk from bacteria such as Legionella. The rules and guidance on managing this vary by country, and responsibility may sit with you, your landlord or both. If your building has these features, check the official guidance and consider getting a competent person to assess the system.

Common mistake

Reopening after a long closure, such as a holiday shutdown or a refit, and letting staff drink straight from taps and coolers that have sat unused for weeks. Flush the outlets, clean the coolers and check filters before people drink. Add this to your reopening checklist.

Hydration in hot weather

June brings longer days and warmer shifts. For staff in kitchens, warehouses, delivery vans, outdoor stalls or busy shop floors, the heat can build quickly. Water is part of the answer, but access and habits matter just as much.

Make water easy to reach. Place water close to where people work, not only in a break room at the far end of the building.
Encourage regular drinks. People often wait until they feel thirsty. A friendly reminder in a shift briefing helps.
Plan breaks. In hot spells, add short extra breaks in a cooler area, especially for physical work.
Watch for warning signs. Train supervisors to notice signs that someone is struggling with the heat, such as dizziness, confusion or heavy sweating, and to act quickly.
Think about new and vulnerable staff. New starters, older workers, pregnant workers and anyone with a health condition may need extra care.

Your heat plan does not need to be long. A one-page note covering where water is, when extra breaks start and who to tell if someone feels unwell is a strong start. If you employ staff in the UK, link it to your written risk assessment.

Hypothetical example

Marcus runs a small bakery with four staff. In the first hot week of June, one baker felt faint near the ovens. Marcus moved a water dispenser right next to the prep area, added two short breaks to the morning shift in hot weather, gave everyone a refillable bottle and put a simple note on the wall about what to do if someone feels unwell. He also added the dispenser to his weekly cleaning log. Nobody missed a shift through the rest of the summer.

Water for customers and visitors

If customers spend time on your premises, such as in a salon, gym, waiting room or event space, offering water is good hospitality and, on hot days, good care. Requirements for customers differ from those for staff and vary by location and business type, so check local rules if you run a venue, a gym or a food business.

Keep customer water points clean and stocked, with cups or a refill option.
Label any tap that is not drinking water, such as a cleaning sink.
If you serve food or drink, your water and ice handling will also fall under food hygiene rules, so follow your local food safety guidance.

A water point log template

Copy this table into a spreadsheet or print it and pin it near each water point. The dates and names below are made-up examples for illustration only.

Water point	Type	Cleaning frequency (example)	Filter due (example)	Last checked	Owner	Notes
Kitchen tap	Mains tap	Daily wipe	Not applicable	10 June	Sam	Drinking water sign in place
Shop floor cooler	Bottled cooler	Weekly clean	Not applicable	9 June	Alex	Two spare bottles stored in the stock room
Warehouse fountain	Plumbed fountain	Twice weekly	1 August	8 June	Jordan	Flush after weekend closure

Review the log once a month. Gaps in the "last checked" column tell you where the routine is slipping before it becomes a problem.

Signs, training and communication

Good water safety depends on people knowing what is safe and where to go. A few small touches make a big difference.

Clear signs. Mark drinking water points, and label any outlet that is not safe to drink from.
Onboarding note. Tell new starters where water is and how the hot weather plan works.
Easy reporting. Make it simple for anyone to report a dirty fountain, an empty cooler or a strange taste. A message to a named person or a note on a shared board is enough.
Supplier contacts. Keep the cooler supplier's contact details and your plumber's number in one place.

Frequently asked questions

Do I have to provide bottled water, or is tap water enough?

In many workplaces, a clean mains tap in a suitable place meets the requirement. Bottled water or coolers are useful where taps are not practical. Check your local rules and the official guidance for your type of work.

Who is responsible for water safety if I rent my premises?

It can be shared. Landlords are often responsible for the building's water system, while you are responsible for providing drinking water to your workers and keeping your own equipment clean. Check your lease and agree responsibilities in writing.

How often should I clean a water cooler?

Follow the manufacturer's instructions and your supplier's guidance. Wipe touch points often, and do a deeper clean on the schedule they recommend. Busy or dusty spaces may need more frequent attention.

What should I do if the water tastes or looks strange?

Stop using that outlet, put up a sign, provide another source of drinking water and contact your water supplier, landlord or plumber. Do not let people drink from it until the cause is found.

The bottom line

Safe drinking water at work comes down to three things: a reliable supply that people can reach easily, a cleaning routine with a named owner, and a plan for hot days. Check the rules where you operate, label clearly and keep a simple log.

Spend an hour this week walking your building, listing every water point and filling in the template. It is one of the cheapest ways to show your team that you take their wellbeing seriously.
