Reverse Osmosis & Water Treatment in Laos

Laos, offically known as The Lao People's Democratic Republic (Lao PDR) is a landlocked country in the Indochina peninsula with a total area of 236,800 square kilometers (km2). The country stretches more than 1,700 kilometers (km) along a north-south axis. Some 80 percent of the country’s area consists of hills and mountains. The highest point is the Phu Bia at 2,820 meters (m) above sea level. Administratively, Lao PDR is divided into 17 provinces plus the municipality of the capital, Vientiane. 

River Basins and International Rivers
 
The Mekong River is the main river in Lao PDR. Forming the border with Thailand, in Lao PDR it flows for about 1,860 km, of which almost every part is navigable. The Mekong River basin covers 90 percent of the total area of the country. About 25 percent of the Mekong River basin is located in Lao PDR, which contributes 35 percent of the Mekong’s total flow. The main tributaries of the Mekong River in Lao PDR are, from north to south, the Nam Où (11 percent of the area of the country), Nam Ngun (6 percent), Nam Theun (7 percent), Xe Banghieng (9 percent), and Xe Kong (10 percent). The Lao part of the Mekong River basin is divided into 32 sub-basins for planning purposes. 
 
In addition to the Mekong, six small river basins drain from Lao PDR towards Vietnam: the Tale, Nam Ma, Nam Mat and Nam Xa rivers, and two others, the Nam Luang and Nam Mô, meet in Viet Nam before reaching the sea. 
 
Water Resources
 
A significant part of the water resources of Lao PDR come from neighbouring countries, namely 73.63 cubic kilometers per year (km3/year) from China and 17.6 km3/year from Myanmar while the outflow from Lao PDR to other countries consists mainly of the Mekong River to Cambodia (324.45 km3/year at Paksé) and small rivers, the Ca and Ma rivers (9.1 km3/year), to Vietnam. 
 
The internal surface water resources have been estimated as the difference between the outflow and the inflow to the country, i.e. 190.42 km3/year, while groundwater resources are roughly estimated at 38 km3/year, most forming the base flow of the rivers. The total renewable water resources are therefore estimated at 333.5 km3/year. 
 

The World Bank reports that at least 80 countries have water shortages and 2 billion people lack access to clean water. More disturbingly, the World Health Organization has reported that 1 billion people lack enough water to simply meet their basic needs, unfortunately in many countries water is scarce or contaminated.

 Pure Aqua provides wide range of filtration and economical solutions based on the Laos' water resources.

Laos' main water resources are:

  • Surface water “is water from river, rain water, lake or fresh water wetland, which can be treated using different methods, such as Ultrafiltration SystemsMedia Water FiltersBrackish Water RO.
  • Desalination can be used for water from ocean, or sea source, which can be treated using Sea Water Reverse Osmosis SystemsDesalination Systems
  • Ground Water or brackish water is from water located in the pore space of soil and rock “Borehole well”, which can be treated using Reverse Osmosis Systems, Media Water FiltersChemical DosingUV Sterilizers.
  • Government water supply, which could have high level of hardness or high level of chlorine, can be treated with Water SoftenersMedia Water Filters

Pure Aqua manufacture water treatment systems that meets the World Health Organization requirements.
