2. PUE appliances will improve production and income and reduce work load and overall expenditure of rural businesses
3. Numerous small-scale, off-the-shelf appliances spread across several businesses are more cost effective and less technically vulnerable than single specialised/customised large appliance.
The project was implemented from August to December 2012 by two different non-governmental organisations (NGO), ProWater and Operation Wallacea Trust (OWT), in Sumatra and Sulawesi respectively.
