Building standards to minimize water use in university

Water conservation within university campuses is a critical component of sustainable building management. Implementing effective water-saving strategies not only reduces operational costs but also promotes environmental stewardship. Below are the building standards and procedures adopted to minimize water use across the university:

  1. Regular Maintenance and Repairs
  • The university conducts periodic inspections and maintenance to ensure water taps, pipelines, and connections are in optimal condition.
  • Damaged or leaking fixtures are promptly repaired or replaced to prevent water wastage.
  • Spare parts inventory is maintained to ensure urgent repairs can be completed without delay.
  1. Water-Saving Fixtures
  • Water-saving aerators are installed on washbasin faucets. These innovative solutions dispense water at controlled flow rates, typically between 2 to 8 liters per minute, significantly reducing water consumption.
  • Efficient lavatory faucets with a maximum flow rate of 6 liters per minute (LPM) can reduce water usage by up to 30% compared to standard faucets, without compromising functionality.
  • Dual-flush water-efficient toilets are installed, allowing users to select between a low-volume flush (4 liters) and a higher-volume flush as needed, saving up to 75% of water per use.
  • Efficient water closets, whether single- or dual-flush, consume less than 6 liters per flush, achieving further water savings. Water closets account for approximately 25% of indoor water consumption.
  1. Monitoring and Emergency Response
  • Regular monitoring of toilets, faucets, and other water supply points ensures any leakage or inefficiency is promptly addressed.
  • A rapid response system is in place for emergency water leakage reports, ensuring that necessary measures are taken immediately until permanent repairs are completed.
  1. Landscaping and Irrigation
  • The campus landscape design minimizes water use by reducing grass-covered areas and incorporating native or drought-resistant plants that require minimal irrigation.
  • Sprinkler and drip irrigation systems are employed to efficiently water the surrounding greenery, further reducing potable water consumption.
  1. Rainwater Harvesting and Reuse
  • Rainwater harvesting systems are installed to collect and store rainwater for non-potable uses such as toilet flushing and irrigation.
  • AC condensate collection systems are integrated to reuse water generated by air conditioning units, reducing dependence on potable water sources.
  1. Water Metering and Management
  • Water meters are installed across various buildings and facilities to track water usage and identify opportunities for further conservation.
  • A centralized water management system supports continuous monitoring and evaluation, ensuring water efficiency goals are met and associated costs and environmental impacts are minimized.
  1. Educational Initiatives and Awareness Programs
  • Awareness campaigns and workshops are conducted to educate students and staff about the importance of water conservation and the role they play in supporting sustainability initiatives.
  • Visual aids such as posters and digital displays are placed in high-traffic areas to remind everyone to use water responsibly.
  1. Advanced Water Recycling Systems
  • The university is exploring and has integrated greywater recycling systems to treat and reuse water from sinks and showers for non-potable purposes, such as irrigation and toilet flushing.
  • Future plans include implementing closed-loop water systems in specific facilities to achieve near-zero water wastage.
