Omeva builds your plan on the WHO method, maps it to the rules where you operate, then runs it every day. Sensors watch the controls that matter, accredited laboratories verify them, and every action leaves evidence an auditor can follow.
Showing rules for . The WHO method is the core everywhere.
Most water safety plans are written for an audit, then filed. The water keeps changing.
Occupancy drops, pipes age, sources shift. A plan that is not watched describes a system that no longer exists.
Lab PDFs, logbooks and inboxes. When something goes wrong, the proof is in five places and none of them agree.
The author leaves; the plan stays behind. Omeva keeps the plan running between audits, with the same people answerable for it.
Live readings, the plan, laboratory results and every action sit in one record for each water system. The Omeva app puts that record in your pocket. It is in development, and the screens below are a preview.
App previewIn development. Screens show illustrative data.
We watch the controls that carry the most risk and bring accredited laboratory results onto the same record.
Built hazard by hazard on the WHO method, then kept current through monitoring, incidents, actions and review.
A result is only as good as the sample behind it. We train the people who take samples and track their certificates in the plan.
The World Health Organization's Water Safety Plan manual (2nd edition, 2023) sets out ten modules, from assembling the team to reviewing the plan. Omeva runs every one of them as part of the service and keeps the evidence for each step. Choose a module to see what we do.
WHO Guidelines for drinking-water quality, 4th edition with the first, second and third addenda (June 2026): health-based targets, water safety plans and independent surveillance.
Same method, building scale. Hospitals, hotels, care homes and portfolios run the ten modules on their internal plumbing, with Legionella in focus.
Scaled to size. Sanitary inspections, a protected source and reliable disinfection, with the same evidence trail.
Answers are grounded in the WHO method and the rules where you operate. Or describe your water system in a sentence or two and get a starter hazard register, scored and ready for your team to review.
General decision support, not a substitute for your responsible person or the current text of the rules that apply to you. If people may be ill, follow your incident procedure and contact your public-health authority. Questions are answered by our AI provider, so leave out personal details.
Omeva only marks a control as safe when the evidence behind it is current and traceable. Missing or stale data shows as insufficient evidence, so a gap is never hidden behind a tick. Every status links to the reading, result or rule that produced it.
Current evidence meets the rule set that applies.
A limit or trend needs review or action.
A defined rule is not met. The incident procedure starts.
Required data is missing, stale or unverifiable.
No rule has been applied yet. Nothing is assumed.
Legionella growth risk if the return loop runs below 55 °C. Scored likelihood 3 × severity 5 = 15, high.
Calorifier set to 60 °C, loop balanced. Thermal profile of 12 outlets on file.
TIT-201 reads every 5 minutes. Alarm after 30 minutes below 55 °C.
Return at 53.9 °C for 42 minutes. Status moves to attention; action A-118 goes to on-call facilities.
Setpoint restored and balancing valve V-7 adjusted. Return back at 57.1 °C.
Sentinel outlets sampled; laboratory reports Legionella not detected. Certificate linked to the sampling points.
Root cause: valve drift. Valve checks added to the maintenance programme (Module 09).
Every line links to its source: the sensor trace, the action record, the laboratory certificate and the approved plan version.
Sensors report every few minutes. Exceptions are reviewed weekly, samples verified monthly, the team meets quarterly and the whole plan is reviewed every year. Omeva runs that rhythm. Below is one illustrative year for one water system.
Probes and scheduled checks on the controls that carry the most risk.
A living map, hazard register and improvement plan that change with the site.
A risk-based sampling programme with any accredited laboratory.
Exceptions become actions with owners, deadlines and proof of closure.
Your organisation keeps its legal duty for safe water. Omeva runs the system that helps you meet it, and shows you, at any moment, what is under control and what is not.
A drinking-water certificate answers one part of the question. A site also needs the right to take its water, and proof that what leaves the site meets its permit. Omeva keeps all three on the same record.
Keep the authority to take water, and the meters and volumes behind it, tied to the system it supplies.
Manage water for its purpose: drinking and food, bathing, process and cooling.
Turn each permit, consent or by‑law condition into a monitored obligation with evidence behind it.
Most sites discharge to a municipal sewer under a permit, consent or by‑law, with limits, sampling rules and charges. Omeva holds the permit and its limits, the sampling programme, laboratory results, flow and pre-treatment records, exceedances and reports, so you can show where you stand at any moment.
We run the compliance record, not the treatment plant. Treatment design, installation and process guarantees stay with your engineers and operators.
The WHO method is the same everywhere. What changes is the law, the limits and who you report to. Every engagement starts by mapping the instruments that apply to your site. Select a row to set your jurisdiction across this page.

Standards and regulations are referenced by name. Omeva does not reproduce them, and a plan always follows the current, licensed text that applies to the site.
The method stays the same; the hazards do not. Each plan starts from what typically goes wrong in your kind of system, then gets specific to yours.
omeva
Omeva means water in Oshiwambo, spoken across northern Namibia and southern Angola. Water is the whole of the job, so it is the whole of the name.
Same team, same technology — a name of our own.
We have done commercial water-safety work since 2019 from Cape Town: continuous monitoring, laboratory integration and compliance reporting for sites across South Africa. Omeva carries that work forward under a name that can travel.
Legionella.ai
Legionella.ai is our specialist guide to Legionella and building water safety, with country-specific rules and a working Ask assistant. The same Omeva plan engine sits underneath.
Visit Legionella.aiOffer water safety plans as a service under your own name. You keep the client relationship and the laboratory work; Omeva runs the plan engine, the evidence trail and the reporting.

The short version of what people ask before they start.
Yes. Tesla Water is now Omeva: same team, same technology, a name of our own. The work we have done since 2019 carries on under the new name.
No. Your organisation keeps its legal duty and your responsible person approves the plan and its changes. Omeva runs the work around them: monitoring, sampling, actions, reviews and the evidence record.
Yes. Omeva works with any accredited laboratory and with third-party sensors. Results arrive as certificates, spreadsheets, email or a direct feed and are linked to the right sampling point. Accreditation is checked method by method.
No. Probes are an early-warning layer on the controls. They do not detect pathogens, so laboratory verification stays in the plan. Sensor data is labelled operational unless its method supports compliance use.
Yes. We turn the conditions in your permit, consent or by‑law into a monitored programme: discharge points and flows, sampling to the permit, laboratory results, exceedances, notifications and reports. Treatment design and process guarantees stay with your engineers and operators. Our free guide sets out the basics.
It is in development. The screens on this page are a preview with illustrative data.
Yours. The WHO method is the core and local instruments are mapped at scoping. Omeva runs South African plans today under SANS 241-1 and 241-2; other jurisdictions are mapped for each engagement.
AI drafts and checks; people decide. Omeva uses AI to suggest hazards, draft sections, read laboratory certificates and explain readings. Every finding links back to its evidence, and your team approves the plan.
Per water system, per month, after a scoping survey. The fee reflects the system's complexity, the points that need continuous monitoring and the laboratory programme the risk assessment calls for.
The method stays the same. The rules, limits and reporting change with the jurisdiction, and so do the answers from Ask Omeva.
