    (Scroll down for full text)

    From June to September 2012, WTA carried out surveys on sludge management systems in Savannakhet and Vientiane Capital.

    A report on survey findings was officially presented in June (what year) to the department of public work and transportation in both towns. Findings also recommended include using green technologies to transform the sludge into humus, which at the end of the chain may help with agricultural or forestry-based activities.

    The recommendations proposed and the implementation schemes were approved by concerned authorities and WTA was mandated to help raise funds to implement the proposed activities.

    WTA spent much of 2013 linking authorities who believed in the merits of the project with potential sponsors who would financially support it.

    This approach led to the grouping of three different funding partners : SIAAP, AIMF and AESN. Their support allowed the WTA experts and their collaborators from GRET and….  to draft a preliminary engineering plan, by  compiling different studies done on the subject.

    2015 was a year of fulfilment and implementation : a tendering procedure was launched to select a company that would ensure the construction of the septict sludge treatment plant, foundation stone in the feacal sludge management project for Vientiane Capital.

    After the company was hired, the project commenced in March 2015.

  • Manual Drilling Techniques: The Key To A Better Access To Water

    Following the success of projects in the Central African Republique (see on this subject : RFI link), WTA continues to develop, and share knowledge on manual drilling techniques with other countries, in order to encourage South-South cooperation.

    The manual drilling techniques have proven to be effective, allowing potable water treatment to take place in the Amazon basin, as well as in the Great Lake regions where water is usually particularly difficult to treat.

    By recycling equipment, it only cost approximatively 1000 dollars to drill manually. This is twenty time less than if one were to use mechanical drilling devices. 

    Manual drilling techniques are easy to maintain and monitor. No chemical products are required and less energy is consumed, resulting in much less operating expenses.

  • Sangthong District, Vientiane Capital: A Water Resources Survey

    At the start of 2016, WTA was mandated to support local authorities from Sangthong district,  Vientiane in gathering information for the purpose of fund raising to enhance drinking-water coverage in the district.

    WTA deployed a team from 25 to 28 March to conduct an economical survey, to understand the constraints in water usage, and to calculate how much people were willing to pay for water. Topographic and site mapping surveys were also provided.

    WTA's team was multidisciplinary, and consisted of socio economic experts, supply, mapping and topography engineers.
