Empirical Decision-Support System for WASH Engineers & Planners

WASH Suitability Selector

Evaluate local ground conditions, raw water hazards, logistics, and demographic scale against international standards (CAWST, Eawag/Sandec, WHO) to determine the most viable, cost-effective water interventions.

Choose the tool edition that matches your project requirements:

Version 1.0 Classic

Standard Empirical Selector

Fast, lightweight empirical multi-criteria screening wizard. Maps site variables across 5 structured steps to deliver ranked technology scores and critical safety barrier warnings.

5-Step Structured Flow: Site, Source, Hazards, Capacity, Logistics
Multi-Source Matching: Ranked abstraction, filtration & storage options
Disqualification Alerts: Immediate hazard & membrane conflict flags
Field-Ready: Low-bandwidth, rapid loading for fast mobile screening
Best for: Rapid field assessments & quick technology checksSelected
Version 2.0 Geo-Engine · Recommended

Advanced Geo-Engineering Engine

Comprehensive hydrogeology GIS modeling, automated solar PV hydraulic sizing, 12-month climate deficit storage sizing, dual-tier hybrid blueprints, and itemized Bill of Quantities (BoQ) budgeting.

Hydrogeology & Risk GIS: Auto-detects Rift Basalt, Fluoride & Arsenic risks
12-Mo Climate & Storage Sizing: Computes dry-season deficit buffer & roof area (m²)
Solar & Hydraulic Sizing: Calculates TDH, m³/day flow rate & array Watt-peak
Itemized BoQ & Seasonal Playbook: Line-item materials/labor budgeting & seasonal guide
Best for: Comprehensive project engineering, hybrid design & budget proposalsSelect V2

Describe previous intervention attempts, mechanical failures, security concerns (e.g. solar panel or cable theft), cultural taste biases, or specific devices already under consideration. The engine will dynamically parse this to adjust suitability scoring.
