Introduction
The WiseWudhu project aimed to address the significant water usage in Masjid Ahmad Ibrahim mosques established in 1961,
particularly during Fridays when Muslims perform ablution (wudhu) before prayers. The project focused on developing a water-
saving device inspired by the traditional practice of the Prophet Muhammad (peace be upon him), who used approximately
775ml of water for ablution. By implementing a water-saving solution, the project sought to reduce water wastage, support
Singapore's Green Plan 2030, and promote sustainable living.

The project successfully designed, prototyped, and tested a water-saving device that integrates a touchless sensor faucet, a
water flow meter, and a microcontroller (ESP32) to regulate water usage. The device was installed at Masjid Ahmad Ibrahim,
and data collected demonstrated a significant reduction in water consumption during ablution.

In areas with significant Muslim populations, Fridays witness a surge in water usage due to the religious practice of ablution
before Friday prayers. Data collected at the mosque revealed that the main wudhu area had a high-water flow rate of
approximately 6.276L/min when taps were fully opened, leading to excessive water consumption and wastage. This trend aligns
with Singapore's Green Plan 2030, which emphasises reducing water consumption in public settings.

Environmental Review CCTV Monitoring:
Data Collection & Analysis A CCTV system was integrated to capture and compile data on
Water Flow Measurement: water usage patterns.
A Wi-Fi IoT water flow meter was installed at the main wudhu Observation:
area to measure water usage during ablution. The team Data revealed that Fridays had the highest water consumption,
decided to collect data at the main wudhu (ablution before with an average of 6.276L/min per tap, as shown in Figure 2
prayers) area (Figure 1) because of its higher foot traffic and
faster water flow rate, approximately 6.276L/min when the tap
is fully opened, compared to other areas. This suggests that
the main wudhu area may have higher water consumption
and wastage than other parts of the mosque.
