waterprenuer
Clean water,
measured to the liter
and made to pay
for itself.
Waterprenuer designs and ships the whole water system in-house, the OASIS Box hardware in the field, the OASISLink platform that proves every liter, and OASIS ATM kiosks that let anyone buy water with a phone. One team, one chain of custody, from the pump to the carbon registry.
Gold Standard · GS11721
USPTO · PatentedThree products. One water economy.
Each stands on its own, and together they close the loop from clean-water delivery to measurable, monetizable impact.
The physical layer. A solar-powered water dispenser and monitoring unit engineered for off-grid sites, combining flow metering, water-quality sensing, GPS and case-open tamper detection, phoning home over GSM without needing local internet.
- 01Flow · TDS · GPS at the source: liters dispensed and water quality captured where it's delivered.
- 02Runs off-grid: solar power and on-board buffering keep data flowing where the grid doesn't reach.
- 03Tamper-aware: reed-switch case sensing and per-device integrity for a credible field record.
The software brain. OASISLink ingests every reading from the field, normalizes and hashes it, and turns raw telemetry into a live fleet dashboard, a tamper-evident audit trail, and the digital MRV backbone for issuing carbon credits from safe drinking water.
- 01Live fleet map & device views: online/offline status, flow and quality charts, and alerts that need action.
- 02Tamper-evident ledger: SHA-256 per reading, append-only storage, hash-chain checkpoints and QC anomaly flags.
- 03Multi-tenant & audit-ready: client/program isolation, role-based access, and access & edit audit logs for verifiers.
The point of sale. A water-kiosk platform where customers buy water with a phone: pay via mobile money, receive a 6-digit code, and redeem it at an offline kiosk. No internet needed at the dispenser; kiosks load codes from a simple export.
- 01Buy water by phone: a consumer app with EasyPaisa & JazzCash checkout, built for low-connectivity markets.
- 02Works fully offline: kiosks redeem pre-loaded numeric codes, so the dispenser never needs a connection.
- 03Admin & pricing built in: tiered volumes, code generation, kiosk management and SMS code delivery.
The hardware, and everything that wraps around it.
The OASIS Box and ATM go in the field, OASISLink measures them, the Portal reports it, and our services keep it running. Carbon credits are an optional add-on - OASIS Box paired with OASISLink, where available. Here is how the pieces compare.
| Product | Key specs & features | Portal & monitoring | Services | Carbon eligibility |
|---|---|---|---|---|
| OASIS Box Hardware · purification Any source into safe water, off-grid. For Implementers, funders |
| Per-unit flow, TDS & uptime on the fleet map, with impact metrics. | Site survey, install, O&M and spare parts. | EligibleAdd-on, via OASISLink dMRV. Live in Kenya & Pakistan. |
| OASISLink Data · dMRV backbone Off-grid water monitoring & dMRV, sold standalone. For operators, carbon buyers, VVBs |
| Powers the Portal - live dashboard, audit trail and CSV exports. | dMRV design, VVB liaison, methodology mapping. | Unlocks carbonWith OASIS Box. Standalone, it’s monitoring, not carbon. |
| OASIS ATM Hardware · kiosk Pay-per-use water on mobile money. For Operators, social enterprises |
| Kiosk map, revenue, transactions & volumes console. | Payment onboarding, pricing, code ops and O&M. | Not eligibleA revenue product for sustainable supply. |
| Carbon is an optional add-on. Pair OASIS Box with OASISLink to unlock Gold Standard credits (GS11721) - currently in Kenya & Pakistan. On its own, OASISLink runs standalone for off-grid water monitoring. | ||||
Why communities choose OASIS over conventional water.
Most safe-water options - RO plants, bottled water, tanker trucking - are power-hungry, hard to run and impossible to verify. The OASIS system is built the opposite way.
| Conventional (RO plants, bottled, trucking) | The OASIS system | |
|---|---|---|
| Power | Grid power or diesel generators | Solar - fully off-grid |
| Operation | Skilled staff on site | Autonomous, monitored remotely |
| Data & proof | Little to none; manual logs | Live dMRV - metered to the litre, tamper-evident |
| Deployment | Civil works, weeks to commission | ~10 minutes, two people |
| Water recovery | RO rejects 30-50% as brine | UF/NF stages recover far more |
| Maintenance | Frequent membrane swaps, skilled techs | Simple filter service, low cost |
| Cost to serve | High capex and running cost | Low cost - and can pay for itself via kiosks |
| Verified impact | Not set up for carbon or reporting | Gold Standard-eligible carbon + live impact |
Products in the field. Services around them.
The OASIS Box, OASISLink and OASIS ATM are the instruments. On top of them we run the services that turn safe water into verified, financed impact.
Built for the field, and already in it.
Every OASIS Box is engineered to run unattended in remote, off-grid conditions: solar-powered, self-monitoring, and dispensing clean water on demand. This is one in service.
Proven in the field, at scale.
The OASIS technology Waterprenuer builds is not a prototype. It is already in the ground, monitored in real time, and recognized by the people and institutions that scrutinize this work.
In the field · PakistanClean water on tapVerified via OASISLink live telemetry: every deployed unit under continuous monitoring - streaming flow and water-quality data across Pakistan, Kenya, Yemen, Afghanistan, Bangladesh and South Sudan, delivering safe water without interruption since 2014.
"OASIS Box just works. Two of our people set a unit up in an afternoon, and the Solar Water Project team keeps every one running and reporting - so we spend our time with the communities we serve, not chasing hardware."

Building water infrastructure? Let's talk.
Running a water program, deploying kiosks, or developing a safe-water carbon project, we can supply the hardware, the platform, or the whole stack.
