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. 

 

 

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, lake or fresh water wetland, which can be treated using different methods, such as Ultrafiltration Systems, Brackish Water RO.
• Desalination can be used for water from ocean, or sea source, which can be treated using Seawater Reverse Osmosis Systems; Desalination 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, Chemical Dosing, UV Water Sterilizers.
• Government water supply, which could have high level of hardness or high level of chlorine, can be treated with Water Softener Systems, Media Water Filters.

Water Treatment Solutions in Laos
Laos is a country with water polluted in dangerous chemicals, animal and human waste, which causes various health concerns. Lack of clean water and sanitation services have harmed the educational attainment of children and families. Particularly, girls in rural areas have difficulties in attending, learning, and returning to school, where the facilities are much poorer. Many rural villages have little knowledge of correct sanitation and hygiene practices. Pure Aqua supplies filtration systems for the purposes of providing quality water treatment in Laos. Many rural communities are unaware of appropriate sanitation and hygiene practices. Approximately 24% of the population practice open defecation, and only 28% of children’s faeces are disposed of safely.

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