RQ 1 — EFFECTIVENESS

DRIP FUNDI Evaluation Synthesis

Baseline (February 2024) & Endline (May 2025) Comparison
Synthesizing findings on borehole uptime, water quality, repair response, and monitoring across 5 ASAL counties in northern Kenya

Program Overview

The Drought Resilience Impact Platform — Fixing Uptime Now and Decision Improvement (DRIP FUNDI) was a $2 million, 18-month program funded by USAID's Bureau for Humanitarian Assistance (BHA) and implemented by the Millennium Water Alliance (MWA) in partnership with Virridy from September 2023 to March 2025. The program targeted 200 boreholes across five ASAL counties in northern Kenya with the goal of providing sustainable water access for 120,000 people.

Theory of Change

IF remote borehole monitoring data is utilized for timely decision-making on repair and maintenance, repair teams are supported to respond to borehole breakdown to improve borehole functionality, and carbon financing generated to sustain repairs, THEN communities in Arid and Semi-Arid Lands will have sustainable access to water for domestic uses.

Four Intermediate Outcomes

Outcome 1: Data for Decision-Making

Borehole data collected and made available to county teams and repair actors through asset inventories, spare parts lists, and sensor dashboards.

Outcome 2: Repairs Within 96 Hours

Broken boreholes repaired within 4 days through leveraging sensor data, timely spare parts access, and BRRT/private sector coordination.

Outcome 3: Monitoring Strengthened

BRRTs and private sector partners trained on accessing and interpreting Virridy sensor dashboards and mobile monitoring tools.

Outcome 4: Alternative Financing

Carbon credit registration with Gold Standard for Global Goals to generate sustainable O&M financing from carbon markets.

Evaluation Methods

Baseline (Feb 2024)

264 boreholes visited
454 household surveys
240 water quality tests
46 KIIs · 15 FGDs

Endline (May 2025)

57 boreholes observed
132 household surveys
65 water quality tests
57 KIIs · 5 FGDs

The baseline was conducted by Losai Management Limited (Nov 2023 – Feb 2024). The endline was conducted by Vision Quest Consultants (Apr 4–13, 2025). Both used mixed-methods approaches including observation checklists, household questionnaires, key informant interviews, focus group discussions, and water quality testing via the mWater platform.


Borehole Uptime

The primary performance indicator for DRIP FUNDI was borehole uptime — defined as the percentage of days when a borehole is operational within a year. The program target was to increase uptime from a baseline of 77% (derived from Virridy sensor data) to 90% annually.

Baseline Uptime
84.4%
259 boreholes assessed
Endline Uptime
85.7%
+1.3 percentage points
Target
90%
Not achieved

The baseline uptime of 84.4% was higher than the initial 77% estimate from sensor data, which was attributed to the selection of boreholes that were largely functional at the time of assessment. The endline showed a modest improvement of 1.3 percentage points to 85.7%, falling short of the 90% target. At the time of endline data collection, 96.5% (55 of 57) boreholes visited were functional.

Uptime by County at Endline

County Boreholes Visited % Broken Down % Repaired
Garissa 8 81% 65%
Isiolo 12 77% 73%
Marsabit 10 86% 76%
Turkana 14 69% 54%
Wajir 13 89% 89%

Wajir was the only county where all broken boreholes were repaired. Turkana had the lowest repair rate at 54%, attributed to accessing spare parts and lack of transportation to remote areas.

Key Uptime Constraints

Major causes of borehole non-functionality

  • Motor and pump system failures account for 40.2% of breakdowns
  • Submersible pump failures account for 26.5% of breakdowns
  • Solar system breakages are a growing cause of failure
  • Conflicts and vandalism (particularly in Turkana)
  • Procurement delays prevent timely repair

Repair Response Time

A central promise of DRIP FUNDI was that broken boreholes would be repaired within 96 hours (4 days) to prevent communities from resorting to unsafe water sources. The endline evaluation revealed a significant gap between this target and actual performance.

Repair Time Distribution (Endline)

0–4 days
2.4%
5–30 days
63.4%
31–60 days
4.9%
61–120 days
14.6%
121+ days
14.6%

Only 2.4% (n=1) of boreholes were repaired within the 4-day target. The majority (63.4%) took 5–30 days. Nearly 30% took more than 60 days, with 14.6% exceeding 121 days. The average notification time for breakdowns was 1–30 days, and the average response time was 2 days to 2 weeks — though response does not necessarily translate to completed repair.

Response Time by County

County Avg. Notification Avg. Response Key Challenges
Garissa 1–2 days 2 weeks Security concerns, hard-to-reach locations, limited parts
Isiolo 6–30 days 2–3 weeks Logistical challenges, long spare parts procurement
Marsabit 2 weeks 2–3 weeks Few skilled personnel, logistical challenges
Turkana 1–2 days 1–3 weeks Spare parts access, lack of transport, security, poor roads
Wajir 1–2 days 1 week Logistical challenges, few human resource personnel

Feedback and Complaints Mechanism

DRIP FUNDI established a Feedback Complaints and Response Mechanism (FCRM) including a toll-free number, SMS line, email, and stakeholder meetings. At endline, 64.4% of households were aware of feedback channels, with in-person reporting to the borehole operator (96.5%) being the dominant method. No households used the toll-free line. Only 17.4% of household respondents had actually used the feedback mechanism.


Water Quality

DRIP FUNDI included inline chlorination via Klorman Inline Chlorinators installed at target boreholes. Water quality testing used the Aquagenx Compartment Bag Test for E. coli and Total Coliform presence/absence, following WHO standards (water should contain <1 CFU/100 mL of E. coli).

Baseline vs. Endline Comparison

Indicator Baseline (Feb 2024) Endline (May 2025) Change
Borehole E. coli positive 50.4% (121/240) Tested at 65 sites
Household E. coli positive 74.6% (170/228)
Households treating water 13% Chlorination + boiling reported
Klorman chlorinators installed 0 (pre-intervention) 24 boreholes treated +24

Baseline Water Quality Findings

The baseline revealed widespread microbiological contamination. At the borehole level, 50.4% of 240 sites tested positive for E. coli. At the household level, contamination was even higher at 74.6% (170 of 228 samples), indicative of post-collection contamination during transport and storage. Only 13% of households reported treating their water, with chlorination and Aqua tabs as the predominant methods. The high borehole contamination was unforeseen and pointed to potential contamination at the water storage unit and possible cross-contamination from animal feces.

Chlorination Challenges

Community resistance to chlorination

  • Communities appreciated water treatment in principle but disliked the taste and smell of chlorine
  • Several boreholes had chlorinators disconnected by operators after community complaints
  • In three endline visits, operators had closed valves through the chlorinator, requiring 30+ minutes to restart flow for FRC testing
  • The program did not adequately create demand for safe water through behavior change communication
  • Recommendation: Social and Behavior Change Communication (SBCC) needed to build acceptance of chlorine treatment

Borehole Functionality Monitoring

Virridy sensors were installed on 153 boreholes across the five counties to enable real-time monitoring of borehole functionality and pumping hours. The sensor data was displayed on dashboards accessible to BRRTs and private sector partners.

Dashboard Utilization

The endline found that both BRRTs and private sector partners had access to and were using the Virridy sensor dashboards and mWater monitoring platform. The dashboards were used for:

However, 57.9% of borehole operators reported they had not been trained on borehole management. Only 12.3% of operators confirmed keeping updated borehole data records. The program over-relied on the sensor without significant human interaction, meaning O&M responses were only triggered when a malfunction was detected.

Systemic Barriers

Both the baseline and endline evaluations identified persistent structural barriers that limited program effectiveness. These cut across institutional, financial, logistical, and human capacity dimensions.

Procurement Delays

County government procurement processes were not adapted for the 96-hour repair target. Procurement for diagnosis, spare parts, and actual repair took far longer, making the 4-day repair window unreachable in most cases.

Spare Parts Scarcity

Spare parts are not readily available locally. Below-ground asset specifications are often unknown until the pump is removed, requiring expensive test-pumping. Parts frequently must be imported or sourced from Nairobi.

Cash Flow Constraints

Private sector partners faced cash-flow challenges that made it difficult to stock spare parts inventory. The result-based financing model required upfront investment that smaller firms could not sustain.

Human Capacity Gaps

57.9% of borehole operators untrained. Limited skilled technicians in remote areas. BRRTs need advanced training on pump diagnostics and solar repair beyond basic data platform use.

Geographic & Security Challenges

Vast distances, poor road conditions, insecurity in some sub-counties, and rainy season flooding limit access to boreholes and delay repair team deployment.

Inadequate Record-Keeping

Only 13 of 57 visited boreholes had complete logs. County teams lacked updated borehole asset inventories, making it difficult to identify compatible replacement components.

"We trust face-to-face the most because we can explain the problem fully and see the person's reaction. It also builds accountability."

Recommendations for Future Programs

The evaluation synthesis highlights both what DRIP FUNDI achieved and where the theory of change encountered friction with on-the-ground realities. The following recommendations emerge from both evaluations.

Modified Procurement

Establish adapted procurement pathways that align with the 96-hour repair target. Consider pre-authorized repair agreements and standby contracts to bypass standard county procurement timelines.

Behavior Change for Chlorination

Include Social and Behavior Change Communication (SBCC) and hygiene education to create demand for safe water and build community acceptance of chlorine treatment before installing chlorinators.

Professionalize O&M

Invest in targeted capacity building for borehole operators and BRRT members on advanced pump diagnostics, solar repair, and preventive maintenance — not just data platform use.

Multi-Use Water Systems

Design for competing water uses (potable, animal, irrigation) to support faster diagnosis, spare parts procurement, and repair when breakdowns affect multiple user groups.

Water Supply System Mapping

Map the complete water supply system for each borehole to identify point sources of contamination and enable targeted water quality interventions.

Diversified Financing

Explore additional funding streams beyond carbon finance — including county budget ring-fencing for WASH, institutional support for budget allocation, and results-based financing models adapted to local cash-flow realities.

Implications for RQ1

What the Evaluations Tell Us About DRIP FUNDI Effectiveness

  • Uptime improvement was modest — 84.4% to 85.7% (1.3 pp), well short of the 90% target, suggesting that sensor-enabled monitoring alone is insufficient without addressing procurement, logistics, and human capacity constraints
  • Repair response fell far short — only 2.4% of repairs completed within 96 hours, indicating systemic barriers that technology cannot bypass
  • Water quality remains a concern — baseline showed 50.4% borehole and 74.6% household E. coli contamination; chlorination uptake was undermined by community resistance
  • Monitoring infrastructure was successfully deployed — 153 sensors installed, dashboards actively used by BRRTs and private sector for decision-making and spare parts prepositioning
  • Community engagement gaps — 52.3% of households unaware of the program; feedback mechanisms heavily reliant on informal in-person channels rather than formal systems
  • The theory of change requires refinement — the assumption that monitoring data leads to timely repairs requires intermediate conditions (adapted procurement, funded spare parts, trained personnel) that were only partially met
