How to build the most scalable and sustainable public toilet model

Hey everybody. I've spent years of my young life thinking about public toilets. A fairly unreasonable amount of time, honestly. Let me take you to a street beside Hussain Sagar.

02The street I grew up with.

A public space has to let people stay.

The street I grew up with.The street I grew up with.

Growing up, I'd come here almost every weekend. Loads of people, something to eat, somewhere to walk. But the toilet was the part you wanted to avoid. Think about women, families and older people. A good public space has to let people stay.

03Let's build it.

One street. One addition at a time.

So, how do we build a public toilet model that scales and lasts? Let me build the idea with you. Here's our street: a food stall, rubbish and inadequate toilet provision. First, clear the rubbish and repair the walking surface. Then put in one integrated LooCafe. The shop is at the front; the toilets are along the side and toward the back. Now give it a clear entrance, signs and some planting. The shop brings an everyday business into the facility. And the panels above it can bring advertising income. The point is to connect the design with a way of keeping it working. Now let's look at the real thing.

04This is the standard LooCafe.

Retail at the front. Toilet access along the side. Advertising above.

This is Banjara Hills. One structure, with different jobs. The shop faces the street. The toilet entrances are along the side. Advertising sits above. But the toilet is the reason the whole thing exists.

05Inside the toilet: privacy, fixtures and finish.

Enclosed cubicles and maintained washing facilities shape the user experience.

Look inside: privacy, a washbasin, fixtures and finishes. The public toilet has to feel like somewhere you can comfortably use—not somewhere you need to escape.

07The entrance is part of the toilet.

Make the facility visible, identify the entrances and keep the approach clear.

08What makes the model worth repeating?

All six have to survive beyond opening day.

These are the values I mean. A usable toilet, a safe approach and privacy. A viable business. Someone checking the work. And a proper destination for the wastewater.

09The front shop helps fund the toilets behind it.

Retail and advertising revenue help pay for cleaning and maintenance.

Why the shop? Because cleaning costs money every day. The business and advertising income help support the toilets. There's also someone present whom you can ask for help. But the toilet is at the forefront. The operating agreement has to connect the business with that responsibility.

10The shop is an operating business.

A working counter at the front helps support toilet care behind it.

Let me show you the shop properly. Here is the fitted counter, and here is a food counter in use at another unit. There is stock, equipment and a person running a business. That business helps pay for care of the public toilets. Advertising provides another income source. The point is to connect an everyday livelihood with an everyday maintenance responsibility. These photographs show different units; they are not a before-and-after pair.

11ACCOUNTABILITY

Notice the fault. Assign the repair. Check the work.

Damaged ceiling · Before section, 9 September 2024Ceiling photograph · Status report, 13 September 2024

Look at the ceiling. This is why accountability matters after opening day. These photographs come from the Dog Park maintenance report. Who notices the fault? Who arranges the repair? Who checks the work? That's the system we need around the building.

12Accountability: record, check, resolve.

A photo record, a second check and a clear route to report a problem.

This illustration explains the accountability loop. It is not an app screenshot. The operator records the work, a supervisor checks it, and problems need an assigned response. The real interface screens belong alongside this explanation.

16A livelihood, with responsibility.

Asif paired a LooCafe Mini with bike repair, and made toilet care part of his day.

This is Asif, from Toilet Tales. He paired a Mini with bike repair, using skills his father taught him. His day began with toilet care, then repair work. That's agency: a business and responsibility for a public service.

The same physical format can also support a different service model. These DRNF-branded counters offer free chai alongside public sanitation. The photographs show the counter and toilet access together. Free chai is a service commitment; we should explain who funds and operates it rather than assume the usual retail economics.

24Our footprint: different cities and settings.

Each location needs a suitable site, a working toilet and a maintenance plan.

Here are different LooCafe settings: Mangalagiri, Chennai and Mumbai. The footprint is more than a number. Space, users and operating conditions change. The model has to travel with a maintenance plan, not just a container.

26A toilet can belong in a well-designed public space.

A clear approach, visible signs and lighting help people find the facility.

Mangalagiri · Approach and plantingTank Bund · Lighting, signs and entrance

You wanted to go for a good stroll. The toilet should feel like it belongs in that public space. Here is the approach at Mangalagiri. Then look at the illuminated frontage at Tank Bund: the entrance, signs and planting are visible together. The photograph shows the design; it does not establish a lighting standard or an accessibility audit. Greenery must not get in the way of the entrance or the person maintaining it.

30But where does the flush go?

Choose the treatment route. Fund the operation. Verify the result.

Now come back to the street. At NTR Marg, our April 2023 letter reported a Mini moved just ten metres, with no drain connection at the new spot. The container moved. The sanitation problem came with it. These CPCB figures show the wider treatment challenge: a historical national baseline, not our results. So where does the flush go, and who keeps that route working?

32Bring treatment to the site.

The service bay contains the treatment equipment behind the public toilets.

Now look at the physical engineering. Here's a factory enclosure, and here are the tanks and pipework inside. The equipment needs space. People need access to inspect it and maintain it. These factory photographs explain the packaging; the precise configuration has to be matched to the installed unit.

35Follow the water.

Collect → treat → disinfect → reuse for flushing

Toilet wastewater is collected and regulated. Biological stages reduce the pollutant load. Further treatment and disinfection prepare the water for flushing reuse. The ECR is additional treatment for high load or unstable effluent in this manual. It is not a box we should casually draw as always running. This is non-drinking reuse.

36The treatment stages—and the return to flushing.

ECR provides additional treatment when required; the reuse route returns water for flushing.

The treatment stages—and the return to flushing.

Let me take you through the water. First, collection and regulation: manage the incoming flow. Then biological treatment. Anaerobic and aerobic stages use microorganisms to reduce the pollutant load; aeration supports the oxygen-dependent stage. Further treatment and disinfection prepare the water for flushing reuse. In the selected BCRT manual, the electrochemical reactor provides additional treatment when the load is high or the effluent is unstable. That's why it's shown as a conditional branch. Finally, the reuse tank and pump return water to flushing. This is a functional explanation of the documented configuration. The important thing is that each stage has a job, and the operating conditions have to support that job.

37The engineering is in the operating limits.

Hardware, operating conditions and daily care have to work together.

The engineering is in the operating limits.

This is why the technology is more than a box in a container. We have to commission the biology, then increase the load in stages. Tank-level controls connect to pump and UV operation; the manual describes suspending use when required. Even cleaning has to work with the treatment process, so the operator needs a compatible cleaning protocol. The hardware, operating conditions and daily routine all have to work together. Then we sample the water and check the result.

42Measure the difference.

Measure water, reliability and treatment quality together.

Our team reports around 400 people a day before launch. Now I want to turn that activity into measured impact: reused water, freshwater makeup, energy, treatment quality and availability. Then add the operator's income and the whole-life cost per use. Those are the numbers a city needs to decide where this service should go next.

46The market: different ways to fund and run a toilet.

Models can overlap. A prefab shell alone does not determine service quality.

This compares operating approaches, not brand rankings. Municipal and pay-per-use toilets can work well. Retail and advertising can support access. ReFlow adds treatment duties; it still needs an operator and maintenance budget.

48The business has to pay for the service.

Compare net contribution with the full cost of staying open.

Sales are not profit. Look at what remains after running the shop. Add committed advertising or service payments. That income must cover toilet operation, plant care and a replacement reserve. Build the business case site by site.

49PPP: agree who provides what.

Public–private partnership is a service contract, not a promise of zero cost.

PPP means public-private partnership. Name what each side provides, who carries each risk, how the service is paid for, and what happens when standards are missed. Agree the allocation for the actual project.

50A contract can cover years of service.

Historical contract scope and recorded progress are different measures.

The August 2020 GHMC certificate describes a fifteen-year concession including operation and maintenance. It describes thirty-six locations but lists four completed. This is evidence of a long-term structure, not a current deployment count.

51Karnataka: procure the whole service.

A site. An operator. Verified treatment. Long-term care.

Karnataka: procure the whole service.

For Karnataka, this is the conversation I'd like us to have. Choose the site and the right treatment route. Name the operator and budget for ongoing care. Verify treatment quality, reuse and availability before scaling. Circular sanitation belongs in policy as a service we fund and measure, alongside the city's wider sewered and non-sewered network.

52Karnataka: start with sites that need a service.

Survey the site before choosing Standard, Mini or a treatment-equipped unit.

Start where a usable toilet is missing or unreliable. Check demand, access, utilities and the wastewater route. Some sites suit Standard, some Mini, and some may justify local treatment. Do not prescribe the same box everywhere.

53Karnataka: put the operating duties in writing.

Specify the service people receive and how it will be checked.

Who opens it? Who cleans it? Who handles a failed pump? Put those duties in the agreement, alongside escalation, inspections and replacement funding. That makes accountability something we can act on.

54Karnataka: measure the pilot before expanding.
