Cordillera Career Development College (CCDC) promotes responsible water consumption by managing and monitoring its campus water sources, combining rainwater harvesting with deep well extraction to support its daily operations. Through these measures, the College seeks to understand its water supply, reduce reliance on groundwater when rainwater is available, and encourage the efficient use of water resources.
As documented in its UI GreenMetric Water Conservation Program Implementation (WR.2) evidence, CCDC maintains a rooftop rainwater catchment system equipped with gutters and downspouts that channel rainwater into storage tanks. The collected water is used primarily for non-potable purposes, including toilet flushing, landscape irrigation, plant watering, and general cleaning. The volume collected varies with rainfall, allowing the College to store more water during rainy periods and supplement its supply with deep well water when precipitation is limited.
The College’s water-use documentation also identifies its deep well as a principal source of water for domestic and operational needs, with a reported pumping flow rate of 78 liters per hour. This figure provides a reference for the well’s reported flow rate; it is not, by itself, the total volume of water consumed by the campus. Actual water use depends on the duration of pumping and the amount of water drawn from each source.
To support water conservation, CCDC has installed water-efficient fixtures, including low-flush water closets, waterless urinals, and efficient washbasins. Routine plumbing inspections and maintenance also help identify leaks and minimize water losses. Together, these measures support more efficient water use across campus.
Measuring total water use requires recording the volume drawn from each source over a defined period. For groundwater, this can be determined through a water meter or by recording pumping duration and verifying the actual flow rate. For harvested rainwater, the College can record the volume collected or released from storage tanks. The volumes from each source can then be consolidated into monthly and annual totals, expressed in liters or cubic meters. Where available, water-meter readings and tank-level records can help validate these figures.
By documenting water drawn from its deep well and rainwater collected and used, CCDC can establish a clearer picture of its total campus water consumption, assess the contribution of rainwater harvesting, and identify further opportunities for conservation. This monitoring approach reinforces the College’s commitment to sustainable water resource management and supports its contribution to Sustainable Development Goal 6: Clean Water and Sanitation.
