ETI: Global Project Success

Track Record


Teams led by ETI have completed studies and projects in over 40 countries around the world.

A sample of projects completed includes:

• Afghanistan (2003): Under a USAID funded program, EarthWater identified 20 billion gallons per day of untapped, renewable groundwater (75 mm m3/d).

• Trinidad (2001 - 2002): Discovered >250 MGDs (946,400 m3/d); produced 20 MGDs (75,700m3/d) within two years.

• Tobago (2000): Discovered >50 MGDs (189,300 m3/d); produced 5 MGDs (18,900 m3/d) within one year.

• Sudan (USAID, 1987 - 1990): Discovered more than 10 MGDs (37,900 m3/d).

• Somalia (USAID, 1984 - 1986): Discovered 20 MGDs (75,700 m3/d); produced 2 MGDs (7,600 m3/d) within one year.

• Seabrook, NH (1981): Discovered and produced 1.5 MGDs within one year (5,700 m3/d).

• Salem, NH (1981): Discovered and produced 2.0 MGDs within one year (7,600 m3/d).

These wells continue to pump without diminishing their respective water tables. Wells currently developed pump in excess of 50 MGDs (189,000 m3/d) globally.

Several case studies are also detailed in the seminal book, Modern Groundwater Exploration, written by ETI’s founder, Robert A. Bisson.

Trinidad & Tobago


· In the twin island nation of Trinidad and Tobago, a 1999 a water development feasibility report prepared by international consultants using conventional hydrological concepts and technologies concluded that Tobago’s potential new groundwater resources were limited to 0.5 Million Gallons per Day (MGD) and Trinidad’s to less than 20.0 MGD.

· Tobago: In 2000, ETI used the Megawatershed paradigm and Bisson’s exploration algorithms to prove the availability of 50 MGD of new groundwater in Tobago or 100x the prior estimates and went on develop over approximately 5 MGD or 10x the previously estimated groundwater potential.

· ETI’s mapped Tobago Megawatersheds now produce approximately 7 MGD and ETI’s wells have reliably produced potable water for over 10 years.

· Trinidad: In 2000-2002, ETI discovered over 250 MGD of new groundwater potential (more than 10x the previous estimates) and since then ETI’s have consistently produced over 20 MGD even during the worst droughts in the islands’ recorded history.

· In Trinidad and Tobago, ETI’s 30 wells represent only 7% of the total number of operating wells (439), but they deliver 44% of all the country’s developed groundwater.
