Monitoring dashboard
Every stream on a satellite map, coloured by forecast risk. Step through the next six days and stress-test storms and heatwaves.
One Health early warning for urban streams
From streams to systems.
StreamReach turns citizen stream checks and the weather forecast into early warnings for waterborne germs, toxic algae and mosquito-borne disease, and delivers them to public health teams and to GPs inside the patient record.

The problem
Two groups watch the same stream and never talk.
Volunteers notice sewage smells, green water and mosquito larvae. Doctors see the diarrhoea, rashes and fevers that follow.
But the observation stays in an app, and the GP never learns that the patient's dog-walking path runs along a stream that overflowed last night. StreamReach connects the two, in the systems each side already uses.
Features
Everything a city needs to act early
Explainable forecasts
Three risk models (sewage germs, toxic algae, mosquito-borne disease) with every factor named, sourced and weighted. No black box.
3-minute stream checks
Citizens answer five plain-language questions based on OneAquaHealth indicators, and see straight away what their check changed.
Alerts inside the EHR
A CDS Hooks service puts stream risk in front of GPs when they open a chart, matched to the patient's symptoms. Two cards at most.
AI duty officer
An AI agent gathers the evidence and drafts a response plan in the local language. A named officer approves it before anything is published.
Built on health standards
HL7 FHIR R4 with the official OneAquaHealth profiles, validated with the HL7 validator. Any FHIR server or EHR can plug in.
How it works
One loop, from the stream bank to the clinic and back
- 01
Citizens check
Foam, flow, algae and larvae, reported in three minutes.
- 02
Forecast
Checks, lab results and the 7-day weather become a daily risk.
- 03
Public health acts
Warnings, what-if planning and AI-drafted advisories, approved by a person.
- 04
Clinicians see it
Relevant alerts appear in the patient chart when it matters.
- 05
The loop closes
GPs share anonymous stream-linked cases, which sharpen the forecast.
