Few households in Vientiane have installed treatment systems for their wastewater before it is discharged into drainage channels and collects in the city's ponds and marshes.
As it seems that many home owners in Vientiane don’t care about wastewater treatment or the quality of the water emanating from their houses, the problem of dirty drainage channels and pollution has continued to worsen.
A staffer at the Bremen Overseas Research and Development Association (BORDA), who asked not to be named, told Vientiane Times on Tuesday that households in the capital normally install septic tanks but do not set up treatment systems for other forms of liquid waste.
