Providing safe drinking water where it’s needed most

Sri Lanka Tsunami Response 2004-β€˜05

In an immediate response to the 2004 Asian tsunami disaster, AdTech Environmental pledged one of its new mobile water purifying plants to the cause. The plant was sent to the Hikkaduwa Province, 16km north of Galle in Sri Lanka - a region devastated by the killer waves.

The plant was commissioned over seven days and began producing clean, safe drinking water on February 18th 2005. Locals affected by the tsunami were made aware of this new resource and directed to the supply of fresh water. The plant immediately began servicing a nearby village with a population of some 350-400 as well as hundreds more displaced people taking refuge in several tent cities that sprung up in the aftermath of the disaster.

Over 1,500 litres of clean water can be produced every hour from polluted sources by this AdTech plant - the smallest of several size options now available. In this case, contaminated well water was pumped to the plant and process steps then included settling of solids, clarification, filtration/adsorption through AdTech's own carbonaceous media, further micro-filtration and final UV disinfection.

For ease of transport and distribution, empty 5 litre 'bladders' (like those found inside wine casks and in fact, provided by a South Australian supplier to the wine industry) were then filled with the resultant clean drinking water and distributed to those in need.

International aid organisations who witnessed the AdTech plant operating in Sri Lanka were amazed at the quality of the water produced.

The AdTech technology helped to prevent tsunami-related deaths caused by disease and thirst. Water-borne disease stalked survivors of the tsunami for some time, with millions of people unable to access clean water. The AdTech plant helped to prevent potential epidemics of killer diseases like cholera and diarrhoea by reducing faecal coliforms in polluted water sources to undetectable levels.
