Handwashing Stations in an Outbreak: Specification and Supply
A handwashing station in an outbreak response belongs at every latrine, health facility entrance and exit, food point and body-handling area, stocked with soap and water or, when neither is on hand, a 0.05% chlorine solution, and refilled at least once a day. Anything less is a station in name only.
What kind of station actually holds up at outbreak scale?
Three types cover almost every field deployment. A bucket-and-tap unit, a jerrycan or drum fitted with a tap and stand, is the cheapest and the fastest to replace, and it is the right default at household level or anywhere traffic is light. A pedal-operated station uses a foot pedal to release water and often soap without the user's hands touching anything, and it is the design UNICEF country offices across Eastern and Southern Africa have standardised on for high-traffic points, alongside knee-operated and back-of-palm variants built for the same reason: a regional compendium of field-tested hands-free designs assembled by UNICEF and IFRC catalogues units from Uganda, Zambia, Madagascar and South Africa built on exactly this logic. Elbow or forearm-operated taps, common on fixed basins inside health facilities, do the same job for a plumbed installation rather than a portable one.
The choice should follow the traffic, not the catalogue. At a cholera treatment unit entrance, a health facility gate or a food distribution queue, a hands-free design earns its extra manufacturing step because it removes the exact touch point the station exists to eliminate. At a single household's shelter, a bucket-and-tap does the same job at a fraction of the cost and is far easier to replace when it breaks. What matters more than the mechanism is what fills it: WHO's hierarchy, reflected in the GTFCC's technical guidance for cholera treatment structures, is soap and safe water first, an alcohol-based hand rub second, and a 0.05% chlorine solution only when neither of those is available. None of that hierarchy matters if the device sits empty, which is a supply and maintenance problem, not a design one.
Where do stations need to go, and how many?
The GTFCC technical note sets out where handwashing stations belong inside a cholera treatment centre or unit: at the entry and exit point, at every latrine, in every patient area, in the kitchen, the laundry area and the waste management zone, and within 20 metres of the morgue. That list is not decoration. It follows the actual points where a hand touches something contaminated and then, without a station in reach, touches a doorframe, a child, or a plate of food next.
The same logic extends past the treatment structure. Anywhere a queue forms or people handle a shared surface before eating or after using a toilet needs its own station, which means food distribution points and communal water points, not just latrines and clinics. UNHCR's WASH manual gives the planning benchmark used at the start of a response: one handwashing point for every eight toilets in the emergency phase, moving toward household-level devices as the settlement stabilises. That ratio, multiplied across dozens of latrine blocks and distribution points, is a procurement quantity, not a rule of thumb to apply site by site.
Placing that many stations is not an abstract planning exercise where caseloads run high. The Democratic Republic of the Congo reported 71,147 cholera cases and 2,071 deaths, a case fatality rate of 2.9%, across the country in 2025, per WHO's cholera epidemiological update. Multiplying station count across that many facilities and distribution points at once is exactly the quantity our supply channel into the Democratic Republic of the Congo is built to plan and deliver against, rather than sourcing one station at a time.
How much soap and chlorine does a station actually use?
The UNHCR standard for household soap is at least 450 grams per person per month, split between 250 grams for personal hygiene and 200 grams for laundry and other use, with a further 250 grams a month provided to women and girls for menstrual hygiene management. That figure underwrites what a household carries home. A shared station at a clinic gate or a distribution point is a separate, additional consumption line, refilled on its own cycle rather than drawn down from a family's ration, and the same UNHCR guidance treats a 50-litre handwash container with a tap and stand as a standard field unit that needs daily refilling and checking, not a fill-and-forget fixture.
Chlorine solution supply follows a stricter rule, because the concentrations are not interchangeable. GTFCC guidance sets three distinct strengths for three distinct jobs: 0.05% for hands when soap and hand rub are both unavailable, 0.2% for surfaces, latrines, equipment and vehicles, and 2% for bodies, stool and vomit. Treat these as different chemistry, not different strengths of one recipe. A 0.2% solution mixed for a floor is a chemical-burn risk on skin, and diluting a 2% body-disposal mix down for handwashing on the assumption it is "stronger, so safer" makes the same mistake in the other direction. Solutions should be pre-mixed, labelled by percentage at the point of use, and mixed only in the volume a shift will actually use, not stockpiled as a single concentrate for volunteers to dilute from memory. Sourcing soap, chlorine and station hardware as one WASH supply line rather than three separate purchase orders is what keeps the percentages and the refill schedule under one team's control instead of scattered across whoever placed each order.
What fails first in the field, and how do you specify around it?
Soap runs out first, then chlorine solution goes stale or gets mixed at the wrong strength, then the physical device itself. On a hands-free design, the tap mechanism or pedal linkage is the first moving part to break, and a plain bucket-and-tap has fewer parts to fail but empties just as fast without a refill schedule behind it. The UNICEF and IFRC compendium of field-tested designs is explicit that a station selected without a plan for a regular supply of consumables and spare parts falls into disrepair, and the secondary effect is worse than the mechanical one: once people learn a station is usually empty or broken, they stop checking it at all, which erases the investment entirely rather than merely reducing its usefulness.
That failure mode is closer to the norm than the exception when specification treats a station as a one-off capital item. The WHO/UNICEF Joint Monitoring Programme's 2019 global baseline report found that only 57% of health care facilities worldwide had functioning hand hygiene facilities at points of care, and that one in six facilities had no hygiene service at all, neither hand hygiene at the point of care nor soap and water at the toilets. That gap is not a design failure; a bucket-and-tap costs almost nothing to build. It is a specification failure, treating the hardware as the deliverable and the soap, chlorine and spare parts behind it as an afterthought.
The fix is to buy the two as one line. Standardise on designs with locally available spare parts rather than the most novel unit in a catalogue, budget soap, chlorine and replacement taps or pedals against station count and refill frequency rather than against a one-time capital cost, and assign a named person to the daily check every piece of guidance above calls for. A station specified this way is a recurring supply commitment, not a purchase order that closes once the hardware arrives.
Frequently asked questions
How many handwashing stations does an outbreak response actually need?
Plan on roughly one handwashing point for every eight toilets during the emergency phase, per UNHCR's WASH manual, then add stations at every entry and exit point, every patient area, the kitchen, the laundry area and within 20 metres of the morgue inside any cholera treatment structure, following GTFCC's placement guidance.
What chlorine concentration should be used for handwashing when soap runs out?
A 0.05% chlorine solution, and only as the third option behind soap and safe water, then an alcohol-based hand rub, per GTFCC's WASH and infection prevention guidance. That is a different, much weaker strength than the 0.2% used for surfaces or the 2% used to disinfect stool, vomit and bodies, and the three should never be substituted for one another.
How much soap does a household need for handwashing and general hygiene each month?
At least 450 grams per person per month under UNHCR's standard, split between 250 grams for personal hygiene and 200 grams for laundry and other use, with an extra 250 grams a month for women and girls for menstrual hygiene management.
What's the practical difference between a bucket-and-tap station and a pedal-operated one?
A bucket-and-tap unit is cheaper, has fewer parts to fail and suits household or low-traffic use. A pedal, knee or elbow-operated station removes the shared touch point entirely, which is worth the added build and maintenance complexity at high-traffic points such as a clinic entrance or a food distribution queue, where the UNICEF and IFRC field-design compendium shows hands-free designs have been standardised across multiple country programmes for that reason.
