Water4

What Water4 does

Water4 is a 501(c)(3) nonprofit founded in 2008 and headquartered in Oklahoma City that builds and operates market-based water utility businesses branded as NUMA across Sub-Saharan Africa. The organization targets rural and peri-urban communities in Ghana, Sierra Leone, Uganda, Zambia, and Kenya that lack reliable access to safe piped water, serving approximately 836,000 customers daily through 21,304 cumulative water projects and employing more than 1,100 local staff to maintain systems. All-time impact is reported at 2,644,904 people served.

The NUMA system is a modular piped-water architecture built around high-capacity boreholes and comprises three integrated components: NUMA Nexus (central well with filtration equipment and storage tanks), NUMA Node (distribution substations branching from the Nexus), and NUMA Now (prepaid metered home and business connections). Water4 has also developed the NuPump, an in-line chlorinator designed for rural health clinics, and operates the Multiply Discipleship Program, which integrates faith-based community development with water infrastructure delivery. The hardware designs have been open-sourced for adoption by other NGOs.

Water4's hybrid business model uses charitable donations as startup capital to establish NUMA franchise businesses, which then sustain operations through customer water payments at approximately $1.20 per 1,000 liters (less than one cent per gallon). Households pay a $100 downpayment for NUMA Now connections plus ongoing usage fees, while vendor-operated kiosks purchase water at wholesale and resell at consumer rates. The organization funds itself through a Major Gifts Officer-led development program, recurring donations, planned giving, and corporate partnerships. Operating franchisees such as 4Ward Development in Ghana covered 84% of operating costs from water revenue in 2021, indicating a still-incomplete transition from grant dependence to commercial sustainability.

Revenue model

1. Water Sales: Customers pay for safe water through NUMA connections. Households pay small fees for access (approximately $1.20 per 1,000 liters), just as they would for electricity or cell phone service. NUMA Now customers purchase water at less than 1 cent per gallon. This is the primary revenue stream that ensures operations, maintenance, and capital replacement occur sustainably. Revenue is customer-reliant, creating direct financial stakes in keeping systems operational.
2. Donations and Charitable Giving: Water4 accepts one-time and recurring donations online, DAF donations through Funraise integration, stock gifts, employer matching gifts, in-kind gifts of equipment/services/assets, and fundraiser campaigns. Donors can also make planned gifts through IRA charitable rollover (up to $100,000 for those over 70.5).
3. Enterprise/franchise revenue: NUMA franchises like Water4Ever in Sierra Leone and 4Ward Development in Ghana operate as businesses selling water, generating their own revenue through water sales while Water4 provides startup capital and support.

Core offering

Water4 is a 501(c)(3) nonprofit that builds and scales durable market-based water businesses (the NUMA Network) across Sub-Saharan Africa. The NUMA system delivers piped safe water to homes, businesses, schools, and community kiosks through a vertical integration of central wells (NUMA Nexus), distribution substations (NUMA Node), and prepaid home connections (NUMA Now). The organization pairs water delivery with WASH education and a faith-based Multiply Discipleship program, and funds initial infrastructure through charitable donations while sustaining operations via customer water fees.

Product overview

Water4 operates a portfolio of market-based safe water businesses across Sub-Saharan Africa through its NUMA franchise model. The core NUMA system consists of three integrated components: NUMA Nexus (the central well and filtration station), NUMA Node (distribution substations), and NUMA Now (prepaid home/business connections). Water is sold at less than 1 cent per liter, with customers paying connection fees and ongoing usage fees to sustain the businesses. Additional offerings include the NuPump chlorinator for hand pump water treatment and the Multiply Discipleship Program for integrated spiritual development. The company employs 1,100+ local staff across Ghana, Sierra Leone, Uganda, Zambia, and Kenya, serving over 836,000 daily customers through 21,304 all-time water projects.

Direct peers

• charity: water: A 501(c)(3) nonprofit that funds clean water projects in developing countries, charity: water shares Water4's donor-driven WASH model, brand storytelling approach (Documentary content, Walk-style events), and ECFA-style accountability standards. While charity: water focuses on funding wells and tracking via sensors rather than operating utilities, both compete for the same faith-aligned and secular major-gift donor pool.
• Water.org: Founded by Matt Damon and Gary White, Water.org pioneers market-based WASH solutions through WaterCredit microfinance, sharing Water4's philosophy of moving beyond charity handouts toward financial sustainability. Both organizations target Sub-Saharan Africa and India with customer-paid water access models, though Water.org uses microfinance while Water4 builds full utility franchises.
• Lifewater International: A Christian nonprofit providing clean water and sanitation in Sub-Saharan Africa and Southeast Asia, Lifewater shares Water4's faith-based positioning and rural WASH focus. Both target similar donor demographics through faith-aligned channels and emphasize community ownership, though Lifewater focuses more on household wells and sanitation while Water4 builds piped utility systems.
• Water Mission: A nonprofit engineering organization providing safe water solutions in developing countries, Water Mission shares Water4's focus on durable, professionally-engineered water systems and integrates faith in its mission. Both organizations emphasize technical quality and long-term sustainability over short-term aid, making them directly comparable in approach if not in geographic focus.
• Water for People: A nonprofit focused on sustainable WASH services in 9 countries across Africa, Latin America, and Asia, Water for People emphasizes "Everyone Forever" — ensuring lasting water access rather than one-time installations. This matches Water4's durability and market-based philosophy, though Water for People works more through government partnerships while Water4 builds direct franchise utilities.

Regional players

• WaterAid America: The U.S. affiliate of WaterAid, WaterAid America shares Water4's U.S. donor-base focus and ECFA-style nonprofit accountability standards. While operating at much larger scale globally, WaterAid America is a direct competitor for the same U.S.-based faith-aligned major donors that fund Water4's NUMA expansion.

Broad incumbents

• WaterAid: One of the largest international WASH NGOs operating across 30+ countries in Sub-Saharan Africa and Asia, WaterAid is a broader incumbent in the same WASH category as Water4. While much larger and more donor-funded, WaterAid shares Water4's focus on rural water access and WASH education, making it the most relevant scale benchmark.

Emerging players

• One Drop: A social enterprise foundation supporting sustainable access to safe water in developing countries via microfinance and social business models, One Drop shares Water4's belief in market-based WASH solutions. Founded by Cirque du Soleil's Guy Laliberté, it operates at smaller scale than Water4 but pursues a similar hybrid of donor capital and earned revenue.
• Waterlines (WaterAid subsidiary): WaterAid's enterprise-focused initiative supporting locally-owned water businesses in low-income markets, WaterLines pursues a similar market-based utility model as Water4. As an initiative within a much larger incumbent (WaterAid), it represents how established WASH NGOs are evolving toward the franchise model Water4 has pioneered.
• WaterEquity: An impact investment manager spun out of Water.org, WaterEquity invests in water and sanitation enterprises serving low-income customers across Africa, Asia, and Latin America. It shares Water4's market-based WASH philosophy but operates through investment capital and enterprise support rather than direct utility ownership and donor-funded capex.
