REGENAQUAEvery drop counts

Every dropcounts.

Student-led engineering, data and outreach for UN SDG 6. We set out to cut our school’s water use by 25% and cut it by 33.6%.

Our problem statement

How can we reduce water consumption and wastage in our school by 25%, creating a blueprint that benefits both our campus and the wider community?

Inside the data

Sensor to
dashboard.

Two sensors watch the system around the clock. Their readings flow to our dashboard, where we track every day and calculate the results.

  1. CT clamp

    Clips around the pump cable and senses its current, so we know exactly when the pump runs and how much electricity it uses. No rewiring.

  2. LiDAR sensor

    Counts people walking into the washroom, without cameras or photos, so we can compare water used with how many people used it.

  3. RegenAqua dashboard

    Combines both streams into daily water use, pump runtime, energy and water per washroom visit, and tracks them against our 25% target.

Modelled An average day rebuilt from our monthly totals (2,32,000 → 1,54,000 L and 276.8 → 166.1 kWh), assuming a 5,000 L tank and a 1.5 kW pump, with pump run times matched to the measured electricity. It will be replaced with day-by-day dashboard readings.

From fixture to campus

Reduce waste at the source.

Hardware, data and student behaviour work together as one campus system, instead of relying on awareness alone. Scroll through the four steps.

Where does it come from?

Every litre wasted at a tap was pumped, stored and carried there first.

Litres per month. The orange dashed line marks our 25% target.

01

Retrofit

Dual-mode aerator nozzles on all 30 washroom and utility faucets take flow from 4.0 L/min to 1.5 L/min. Efficient use becomes the default, not something students must remember.

02

Measure

A current-transformer clamp watches the main water pump and a LiDAR sensor counts people walking into the washroom. Both feed our dashboard, so a pump running when no one needs water stands out as a possible leak.

03

Educate

Workshops connect the global water crisis and Bengaluru's aquifers to the taps students use every day, so they understand where their water comes from and what their choices change. Our outreach has reached 1,000+ people so far.

04

Prove

Meter readings and pump logs show the result: monthly use fell from 2,32,000 to 1,54,000 litres. That is a 33.6% cut against our 25% target, saving 110.7 kWh of pump electricity and 77.5 kg of CO₂ every month.

Our projects

Three connected interventions turn water conservation from an abstract idea into a measurable campus system.

About RegenAqua

RegenAqua is a youth-driven environmental engineering project in Bengaluru. We *retrofit the taps students use every day, *measure what the campus really consumes, and *educate every class so the savings last.

Why start at schools?

Schools are both infrastructure systems and communities. A single intervention can change physical water use while teaching hundreds of students how resource systems work.

Our operational blueprint

Hardware retrofits, sensor data and outreach on campus and beyond work together as one intervention, measured end to end.

Where the drop goes next

The cycle
closes.

After the drain, a drop isn't lost. It takes one of three roads back, and every one ends with it being used again. The orange tags show where our project steps in.
