Water Reservoir Graduation Scale
Measuring Water to Protect Community Health
Manual installation of the graduation scale inside the Laindatang reservoir to measure water levels accurately and protect clean water.
Inside the reservoir, a graduated scale was installed to measure each ten-thousand-litre increment.
This simple and accurate tool enables reliable monitoring of water consumption, prevents waste, and ensures sustainable access to drinking water. In remote villages, the amount of stored water is a vital factor in public health.
The scale was cut, aligned, and manually attached to the inside of the reservoir wall. Despite the low light conditions, the teams from the Fair Future Foundation and Kawan Baik Indonesia ensured that each marking was legible from the reservoir’s inlet hatch. Accuracy is crucial, as even minor errors can impact water management during the dry season.
This graduated scale is not merely decorative; it helps the community anticipate shortages, regulate its daily consumption, and prevent contamination from frequent openings or unsafe access. Combined with internal sealing and light control, it contributes to the long-term stability of water quality.
By integrating measurement into the infrastructure, the reservoir becomes a public health tool. Water quality is maintained not only through filtration and sealing but also through precise knowledge of the remaining water level. This approach is the result of sixteen years of Swiss experience in medical and technical fields.

In Short | When measurement saves water
A straightforward graduation scale transforms a reservoir into a management tool. By accurately measuring the remaining water, communities can plan effectively, safeguard quality, and mitigate risks associated with access. In remote areas, measurement is not just a technical detail; it is a form of prevention.

Measuring water to protect community health
Inside the reservoir, a water graduation scale was installed to measure the volume in every 10,000 litres stored. This precise but straightforward tool allows safe monitoring of consumption, prevents overuse, and supports long-term access to clean water. In remote villages, measuring water accurately is a direct act of health prevention.
The graduation scale was cut, aligned, and fixed manually inside the reservoir wall. Working in low light, teams from Fair Future Foundation and Kawan Baik Indonesia ensured each mark remained readable from the reservoir floor. Accuracy is essential, as even minor errors can affect water planning during the dry season.
This water reservoir graduation scale is not decorative. It allows the community to anticipate shortages, regulate daily use, and avoid contamination caused by frequent opening or unsafe access. Combined with internal sealing and light control, it supports stable water quality over time.
By integrating measurement into infrastructure, the reservoir becomes a medical tool. Clean water is protected not only by filtration and sealing, but by knowing exactly how much remains available. This approach reflects sixteen years of Swiss medical and technical field experience.
