Case Study: Identifying and Addressing Water Wastage in Computer Science Building

The Computer Science building was left unoccupied for a short period of time, during which water consumption data was monitored. It was noted that there was unusually high water usage, prompting further investigation.

Investigation

The Comprehensive System Evaluation (CSE) indicated a high usage of water, which raised concerns about potential leaks or inefficiencies. A thorough investigation revealed two primary sources of water wastage.

  • Running Tap: One tap had been left running continuously.
  • Faulty Toilet Cisterns: Additionally, 10 faulty toilet cisterns were identified, continuously leaking water without detection.

Resolution and Results

Prompt action was taken to rectify the identified issues resulting in the running tap being promptly shut off and the faulty toilet cisterns repaired or replaced to prevent further leakage.

Following this resolution, the consumption of water dramatically decreased, dropping from 1,452m3 in April 2020 to 415m3 in May 2020.

Subsequent months also showed a significant decrease with the overall cost savings amounting to £2,400 per month.

Conclusion

This case study highlights the importance of monitoring and promptly addressing water wastage, even in unoccupied buildings. Through proactive investigation and swift action, significant cost savings can be achieved while promoting environmental sustainability. Regular maintenance and monitoring are essential to ensure efficient management in all University buildings.
