Quadracci Sustainable Engineering Laboratory Quench ensuring water access and visibility for every liter dispensed The School of Engineering at Columbia University’s qSEL laboratory is currently developing Quench, a pay-as-you-go hardware and software platform that offers an enhanced water management solution for rural, urban and peri-urban settings. Currently, consumers are willing to pay the small price for daily water and the associated costs that ensure quality and safety. However, last-mile delivery of drinking water from the utility to the consumer has been a challenge. Current utility payment systems are unreliable and incur high transaction costs. In addition, access to water primarily depends upon attendants that are prone to payment defaults jeopardizing customer service and solvency for the water scheme. Quench’s simple, scalable, and sustainable prepayment platform remedies many of these issues. The Quench Solution: • Pay-As-You-Go, integration with current utility payment systems • Utilizes a simple tamper-proof smart card system for water access. Options for WiFi or cellular access available • Tight accounting of attendant purchases, vendor/co-op book-keeping, and utility sales/receivables • Data collection and metric analysis of operation and transactions • Modular design- can be adapted for homes, taps, kiosks, water tanks or an entire piping network • Daily consumer lifeline amounts can be pre- allocated and can vary by season • Open hardware/software systems Robust Construction and Simple to Use Quench has a rugged, low-cost and easily maintained modular design with plug and play components. During maintenance, the system can be converted to manual operation, allowing for continued water access. Extremely low power, inline units for retrofitting current kiosks as well as new single tap stand designs have been built and are ready for piloting. Features for Governments and Operators • Quench makes water schemes transparent. The system provides auditable transaction logs, allowing governments and donors to create performance-based contracts with water suppliers, ensuring improved maintenance of water points • Local operators can design a payment model that fits their customers’ needs, including pay-as-you-go, pre/post paid usage or part free/subsidized service • Can retrofitted to existing kiosks/taps or newly installed with existing water system • Kiosk unit features a rugged, anti-tamper weatherproof design with plug and play components • Kiosk can operate during maintenance • Team willing to carry out tech transfer or help scale manufacturing: design modifications, maintenance • Quench can connect to cellular/wireless networks to enable real-time metering and system monitoring. • Very low power operation with solar, battery or line power options • Simple, Sustainable, Scalable
