A Motorcycle Rider-Based Surveillance Concept for Lango Sub-Region

The Challenge

Across Lango Sub-Region, hundreds of thousands of people rely on handpumps for their daily drinking water. Nine districts—Apac, Alebtong, Amolatar, Dokolo, Kole, Lira, Otuke, Oyam, and Kwania—depend on these sources for the majority of rural water supply. Yet routine water quality testing at these dispersed points remains a critical gap.

Recent studies across northern Uganda reveal alarming contamination patterns. In neighbouring districts, dangerous levels of lead, manganese, ammonia, E. coli, and total coliforms have been found across numerous boreholes. Local water quality assessments in Lango have shown that aggressive groundwater chemistry—particularly low pH and high salinity—actively corrodes galvanised iron components, leaching metals into drinking water while creating entry points for surface contaminants.

The problem is that functionality checks—whether a pump produces water—miss these invisible but deadly water quality failures. Contamination from poorly constructed pit latrines, seasonal flooding from Lake Kyoga and its tributaries, and corroded components goes undetected until illness strikes communities already burdened by waterborne diseases.

The Solution: Mobile Water Quality Surveillance for Lango

We are deploying manual motorcycle riders recruited from local Lango communities, equipped with portable water quality test kits, to conduct routine handpump monitoring across a defined cluster of districts over six months.

Each rider operates independently within an assigned zone—selected to reflect Lango’s distinct dry and wet seasons, its mix of lakeshore, riverine, and interior communities, and the practical travel distances between handpumps. Together, the team can test between 200 and 400 handpumps multiple times, establishing the first systematic water quality baseline for the sub-region while tracking critical variations between dry and wet seasons.

How It Works

At each handpump, riders:

1. Sanitise the pump spout and flush standing water

2. Collect a sterile water sample

3. Test for key parameters including pH, turbidity, conductivity, E. coli, iron, and nitrate—with special attention to corrosion indicators given Lango’s known groundwater chemistry

4. Record GPS coordinates, photos, and results using a smartphone

5. Communicate results by leaving a simple safety card in the local language (Acholi or Luo) with the community water user committee

Data flows to a central dashboard at the district water office, showing a colour-coded map:

🟢 Green – Safe for drinking

🟡 Yellow – Caution, requires monitoring

🔴 Red – High risk, immediate alert triggered

Why Lango Sub-Region?

Key Objectives

Equipment per Rider

• Motorcycle – 125cc-200cc durable trail bike suitable for Lango’s terrain (paved roads, murram tracks, and seasonal wetlands)

• Test Kit – Portable kit for microbiological and chemical parameters, with extra reagents for iron and pH given local corrosion risks

• Smartphone – GPS-enabled with offline data collection app (network coverage is generally good in trading centres but limited in deep rural areas)

• Cooler box – For sample transport during longer distances between pumps

• Safety gear – Helmet, reflective vest, first aid kit, rain gear for wet season travel

Expected Outcomes

✅ A comprehensive digital database of tested Lango handpumps with GPS coordinates and water quality results

✅ A GIS map visualising contamination hotspots across the nine districts

✅ Six-month trend analysis showing seasonal water quality variations, including flood impacts

✅ Identification of specific handpumps requiring rehabilitation due to corrosion damage

✅ Standard operating procedures tailored to Lango’s conditions

✅ A trained local workforce of Lango residents capable of continuing monitoring

Risk Management for Lango Context

Sustainability

The six-month pilot is designed as a proof-of-concept for long-term integration into Lango’s district water monitoring frameworks. In Month 5, district water officers from participating districts are trained in system operation.

At project close, all equipment transfers to district ownership alongside:

• Full Lango Sub-Region dataset (CSV, GIS Shapefile formats)

• Standard operating procedures adapted for local conditions

• Training materials in English and local languages

• Integration recommendations for each of the nine districts

The low capital and operational costs make this approach feasible for district-level budgets—especially compared to the public health costs of untreated waterborne disease in a region where access to health facilities is already limited.

Conclusion

Lango Sub-Region faces a silent crisis: handpumps that appear functional but deliver contaminated water. With over 8,000 pumps serving hundreds of thousands of people across nine districts, and with known groundwater chemistry that actively corrodes infrastructure while enabling surface contamination, the need for systematic water quality monitoring has never been more urgent.

Motorcycle rider-based surveillance offers a practical, scalable solution grounded in Lango’s existing transport networks and local knowledge. By bringing testing directly to each water point on a routine schedule—and by training local residents to own and operate the system—this approach closes the information gap that currently allows contaminated water to be consumed unknowingly.

The path forward is clear: from reactive crisis response to proactive water safety management, built by and for the communities of Lango.
