Evaluation techniques for household water treatment projects: biosand filter pilot project in Lao PDR
conference contribution
posted on 2018-02-12, 15:09 authored by Betman Bhandari, Ron Lentz, B. SuvanthongRecently, many UN agencies have been promoting the household water treatment (HWT) as a viable way to
begin meeting the needs of millions who lack access to safe water. This paper describes an approach that
was used in a recent evaluation of a biosand filter (BSF) pilot project in a peri urban community located in
Vientiane municipality, Lao PDR. Simple evaluation techniques such as household surveys, water quality
testing, filter performance assessment and observations on safe water storage, source protection and sanitary
conditions were used. These techniques captured user perceptions, water quality indicators, fulfilment of
operating parameters, and filter effectiveness and acceptability. This approach can help project
implementers and end users to understand project effectiveness and contribute to effective followup
programs to overcome barriers to proper use of the filters and the handling of safe water.
