Sampling

Guidelines and procedures for water quality sampling under the K-WASH program

Sampling is used by the Independent Verification Agent (IVA) during each verification round to assess whether counties have met the Disbursement Linked Indicator (DLI) requirements. The methodology below outlines how observations are selected and verified for each DLI.

Sampling Methodology by DLI

DLI Observation Sampling Approach Changing Recommended Sample
DLI 1 Institutional strengthening outputs Census (full review) No 100%
DLI 2 Households with improved water services Stratified random sampling Yes 30% of water points per county
DLI 3 Sustainable water schemes Stratified random sampling Yes 30% of schemes per county
DLI 4 Improved sanitation facilities (schools) Stratified random sampling Yes 30% of schools per county
DLI 5 Improved sanitation facilities (communities) Stratified random sampling Yes 30% of facilities per county
DLI 6 Hygiene promotion activities Purposive sampling No 5 communities per county
DLI 7 Water quality monitoring systems Census (full review) No 100%
DLI 8–12 Program management & institutional indicators Census / desk review No 100% (document review)

Key Notes on Sampling

  • Stratified random sampling ensures geographic coverage — the IVA samples from different sub-counties within each county.

  • Even when sampling is used, the 80% rule applies: if less than 80% of sampled results are eligible, the county receives no disbursement for that DLI in that period.

  • Counties should prepare all reported results for verification, not just the expected sample — the IVA may expand sampling if issues are found.
