Drinkwell & Narayanganj City Corporation (NCC) are improving water access with decentralized water ATMs

Problem:

• Narayanganj’s aging water network provides limited, low-quality supply, leaving many residents, particularly in low-income communities, to rely on contaminated groundwater and surface water sources.

Solution:

• Drinkwell’s water ATMs treat source water using patented ion-exchange resins for arsenic and fluoride removal, providing safe drinking water communities not reliably reached by existing piped water networks.

Pilot Scope:

• Drinkwell piloted 2 water ATMs delivering 1,000 liters of drinking water per hour to urban residents of NCC. The pilot led to a 10x commitment from a foundation alongside in-principle support from NCC to scale to 27 ATMs.

Matter & Urban Drainage Company are increasing urban flood resilience with real-time stormwater monitoring 

Problem:

• Ho Chi Minh City experiences frequent flooding from heavy rainfall and high tides, and struggles to detect and respond to rapidly changing stormwater conditions due to a reliance on manual pit inspections.

Solution:

• Matter’s stormwater sensing platform continuously monitors water levels in stormwater pits, providing real-time data and early flood alerts to support faster response.

Pilot Scope:

• Matter is deploying 18 sensors in 15 locations across Ho Chi Minh City, providing 24/7 monitoring of surges and slow-clearing events to reduce the time taken for UDC to locate and address critical blockages.

SmartTerra, PDAM Depok & PDAM Surabaya are reducing NRW with AI analytics

Problem:

• Water utilities across Indonesia lose an average of 34% of treated water through leaks, faulty meters, and unauthorized connections, while many conventional solutions require extensive digital infrastructure.

Solution:

• SmartTerra’s AI-powered analytics platform combines data analytics, digital workflows, and targeted field services to help utilities reduce real and apparent water losses without additional infrastructural investment.

Pilot Scope:

• SmartTerra is deploying its AI-powered data analytics tool with both utilities to identify likely leak locations, faulty meters, and illegal connections. The pilot aims to reduce NRW by 2% in monitored district metered areas.

Solar Water Solutions & Nhon Chau Island Water Supply Department are improving water security with decentralized seawater desalination

Problem:

• Nhon Chau island lacks reliable water sources, forcing residents to rely on expensive water shipped from the mainland, especially during the dry season where average per capita water availability is <30L/day.

Solution:

• Solar Water Solutions’ solar-powered desalination system delivers drinking water directly from seawater without requiring grid connection or diesel, reducing energy use by 80% compared with conventional diesel-powered systems.

Pilot Scope:

• Solar Water Solutions is piloting its desalination unit on Nhon Chau island and will provide up to 9.6 m³ of drinking water per day for the island’s 2,300 residents in a cost-effective manner.
