Clara Water AG designs and deploys solar-powered electrochlorination systems that generate disinfectant on-site directly from salt and water — permanently eliminating dependence on chlorine chemical supply chains. Our systems dose automatically based on real-time flow and water quality conditions, and are remotely monitored via AI-enabled dashboards, giving operators and NGO partners continuous, verified assurance that water is safe at every delivery point.

Our product range covers the full spectrum of water infrastructure needs:

Autochlor — compact, kiosk-scale units (10–20 m³/day) for community water points, residential and humanitarian deployments.

CLARA Standard — mid-scale systems for hospitals, health facilities, and small utilities (up to200 m³/day).

Lake & Harbour — large-scale urban systems for water utilities treating surface water (up to 9,000 m³/day).

All systems are designed for low-skill operation and minimal maintenance, with standardised installation protocols suited to remote and resource-constrained environments. A Innosuisse-funded R&D programme (CHF 1M+) in collaboration with Eawag is advancing next-generation features including further cost reduction, increased reliability, and enhanced smart monitoring.

Clara Water has active deployments in Ethiopia, Kenya, Uganda, Madagascar, working alongside UN agencies, international NGOs, government ministries, and water utilities.

No chlorine supply chain. Disinfectant is generated electrolytically on-site from salt — no chemical procurement, no transport, no storage risk. This dramatically reduces operational cost (up to 90% compared to conventional chlorination) and removes a chronic bottleneck in remote and fragile-context WASH programmes.

Automated, flow-proportional dosing. Systems continuously adjust chlorine output based on water flow and conditions, maintaining consistent free residual at every delivery point — preventing recontamination that undermines last-mile water safety.

AI-enabled remote monitoring. Operators and programme managers receive real-time performance data via cloud dashboard, enabling rapid issue detection and evidence-based reporting to funders and governments — without requiring skilled staff on-site.

Solar-powered and off-grid ready. All systems run on solar energy, making them deployable in areas without reliable grid electricity. Low energy consumption and minimal consumables keep lifecycle costs low.

Scalable and replicable. A standardised install-and-service model, combined with remote QA, allows rapid scale across many sites. Carbon credit and blended finance mechanisms are being developed to unlock infrastructure expansion without depending solely on grant funding.

Independently validated impact. Research by Eawag and the Ethiopian Public Health Institute documented E. coli-free water samples rising from 5% at baseline to 67% post-installation, with ongoing design improvements targeting 95%+ verified compliance.
