Sunlabob completes construction of sanitation plant at NAFC

On 11 Feb 2011, Sunlabob in corporation with the Lao Institute of Renewable Energy and Bremen Overseas Research and Development Association (LIRE-BORDA) completed the construction of the Decentralised Wastewater Treatment System (DEWATS), a sustainable sanitation plant, at the newly built dormitory at the Northern Agriculture and Forestry College (NAFC) in Luang Prabang.

As soon as other components of the dormitory are finished, the plant will be in operation and treat wastewater for over 200 staff and students in the campus.

Conventionally, sewage networks need to be centralised, where high infrastructure investment, maintenance cost and skilled technicians are required. The DEWATS system however is a sustainable alternative for areas where centralised sewage system is hard to set up and is inexpensive due to its low operation and maintenance costs. As a decentralised system, DEWATS can be adjusted to local conditions to fit the needs of the respective user, even down to a single household. DEWATS is centered on using biological and mechanical modules, thus functions without energy input, making it a low-cost maintenance system. It also does not require highly skilled labour.

The construction of the DEWATS system at the college is intended to serve as a demonstration site for similar locations as an appropriate school based sanitation component. In Laos only 18% of schools have access to wastewater treatment systems.

Sunlabob will visit the college again to conduct a pre-commissioning of the system, and run a training session for the operators to teach them how to operate and maintain the DEWATS system effectively.
