The Bremen Overseas Research and Development Agency (BORDA) has a mission to improve the living conditions of disadvantaged communities and to preserve the environment through decentralized sanitation projects. As part of this mission, the Agency has developed modular, decentralized, and cost-effective wastewater treatment service packages that they have termed ‘DEWATS’ – decentralized wastewater treatment systems, which, with the help of funding agencies, are being installed throughout Asia and Africa.
The Lao People’s Democratic Republic is a country surrounded by China, Vietnam, Thailand, Cambodia and Myanmar. In 2005, Lao PDR was below average in establishing sanitation access as compared to other Southeast Asian countries. In a study conducted by a Multiple Indicator Cluster Survey in 2006 (MICS III), it reflected a 44.8% coverage for those with improved sanitation (or 48% cited by the UNICEF/WHO Joint Monitoring Program) as compared to the 67% average for all the Southeast Asian countries. In the same study, there are at least fifty-two percent (52%) of the Lao population without access to sanitation. This data equates to over three million Laotians living without improved sanitation - without an easily accessible, private and safe place to urinate and defecate. Furthermore, the growing population of Lao PDR needs to be taken into consideration while looking at the efforts to increase sanitation coverage.

    The primary effluent of a Municipal Wastewater Treatment Plant (MWWTP) is monitored to understand organic loading going to the next stage of treatment, the activated sludge process. This process removes organics via consumption by microorganisms living in the sludge. Knowing the composition of incoming primary effluent is important to prevent organic overloading and improve process optimization with the opportunity to save on energy and chemicals. The traditional method for measuring organic load is biological...
