Problem vs Solution

What's broken. How we fix it.

⚠ The ProblemUrban Sanitation Today

✕
Less than 30% of public toilets remain functional in Nepal's cities
✕
Unsafe, unhygienic conditions that undermine human dignity and public health
✕
No menstrual hygiene facilities — women face dangerous conditions monthly
✕
No safe, women-accessible sanitation forcing open defecation
✕
Raw sewage discharged into the Bagmati, Bishnumati and other rivers
✕
No viable maintenance funding — facilities collapse without subsidy

Core Pillars

Six pillars of every HUB

Technology, equity, and circular economics integrated into one self-sustaining platform.

Hygienic Smart Facilities

Touchless fixtures, automated cleaning alerts, air-quality sensors, and odor monitoring — every operating hour.

MHM-Friendly Design

Sanitary vending, hygienic disposal bins, privacy screens, and changing facilities in every women's section.

Gender & Disability Inclusive

Dedicated female sections, full wheelchair access, baby-care, safety lighting — standard in all HUBs.

Waste-to-Energy

Sealed bio-digesters convert 100% of waste to biogas and organic fertilizer. Zero river discharge — by design.

IoT Monitoring Dashboard

Live occupancy, cleanliness, energy output, and maintenance metrics for operators and municipalities.

Revenue-Generating Model

Five income streams create a reliable surplus — fees, biogas, fertilizer, advertising, training licences.

Financial Architecture

Five revenue streams. Zero subsidies.

Each income stream is independent — combined they create a durable surplus that funds expansion.
