Water Projects
Find and fund the most effective water projects globally. Filter by tax status, cost-effectiveness, and project type.

Blood: Water Mission
Launched first project in 2005, focused on clean water and sanitation in African communities with a holistic, community-driven approach.
Niche but impactful, smaller scale.

Borama BioSand Filter Project (Somaliland)
Household-level biosand filter evaluation in Borama, Somaliland, using zeolite-modified filter media. The study confirmed pathogen and turbidity reduction with a reported unit construction cost below US$20 per filter.
[Original Cost: <US$20.00 (USD)] Extremely low hardware cost (<$20/unit) and simple local construction make this highly scalable for communities lacking centralized treatment, though the source does not specify household size or establish a direct donor funding channel.

Charity: Water
Drills deep boreholes fitted with robust handpumps and builds piped solar water networks. Collaborates directly with verified local regional operators to ensure lifelong project maintenance.
UK Registered Charity. Eligible for Gift Aid, which increases the impact of every pound contributed by UK taxpayers. Highly transparent field reporting.

Community Transformation Trust (CTT) Water Filters
Partners with GHNI to provide water filters to families in Egypt, and funds Village Drills for remote communities in Liberia and Sierra Leone.
Grassroots organization providing direct intervention. $120 funds a water filter for a family. Donations are tax-deductible in New Zealand.

Drop in the Bucket - Uganda Borehole Wells
Drills 50-meter deep borehole wells in Uganda equipped with India Mk II hand pumps. A typical well costs approximately $7,500. The charity mobilizes to drill multiple wells in a region simultaneously to share transport costs and improve efficiency.
[Original Cost: $7,500 (USD)] Transporting drilling rigs and crews to remote villages is a major cost driver; drilling at least ten wells per mobilization significantly reduces the average cost per well. Each project includes community mobilization, sanitation and hygiene training, and a monitoring plan.

EA NZ - GiveWell Water Quality Interventions
Supports GiveWell's top-rated water charities like Evidence Action's Dispensers for Safe Water. Donations made through EA NZ are tax-deductible in New Zealand.

Focuses heavily on follow-up and maintenance, reporting 98.3% of filters still working after installation. Tax-exempt 501(c)(3) in the USA.

GiveWell - Chlorination Programs
Funds water chlorination programs in low- and middle-income countries. Highly cost-effective, with over $125 million granted since 2017. Reduces waterborne disease.
Extremely low-cost intervention. The $2 per person annual cost makes it among the most cost-effective water charities.

GiveWell Water Quality Interventions
Grants for water chlorination programs in low- and middle-income countries, with over $125 million provided since 2017.
Highly cost-effective and evidence-based, but large-scale and not direct individual donation routing.

ReliefAid Gaza Emergency Water Distribution
Delivering safe drinking water to families in displacement camps across Gaza. Sourced from local boreholes and treated using operational desalination plants to ensure distribution is independent of border crossings.
Highly cost-effective emergency intervention in a major conflict zone, bypassing border dependency by sourcing water from active boreholes treated locally. Extremely high immediate survival impact.

Sabaki Water Project - Large-Scale Piped System
The Sabaki Water Project in Kenya provides 80 million liters of water per day to over 650,000 people. It uses a 20-year operation phase before handover.
Large-scale piped systems can serve many people efficiently over a long lifespan.

SAPA WASH Program - Water Well Drilling
The Sudanese American Physicians Association drills standard and deep borehole wells across Africa through its WASH Program. Standard boreholes or hand-dug wells range from $5,000 to $15,000, while deep wells up to 900 feet exceed $20,000. Projects include forming village water committees for maintenance.
[Original Cost: $5,000 to $15,000 (USD)] Without maintenance, 30-50% of wells fail within five years. Community maintenance training adds $500-$1,000 per project but is critical for ensuring wells last 20+ years. Deep wells in arid regions access stable aquifers and can serve large communities for decades.

Sawyer PointONE Household Filtration (Scout Verification)
Distribution of hollow-fiber membrane point-of-use gravity filtration kits to remote households in rural areas prone to bacterial waterborne disease outbreaks.
[Original Cost: $45 per kit (USD)] Provides immediate, biological safety. Extremely low maintenance and high lifespan make it perfect for remote households, though it requires community training to ensure proper backwashing.
