Reducing water consumption
SMART targets are Specific, Measurable, Attainable, Relevant and Time-bound.
- Energy SMART targets (pdf)
To do this the College will:
- Operate a water management system which closely monitors water usage across campuses and departments and to compare actual performance with published targets.
- Introduce leak detection systems to help identify and report leaks efficiently.
- Regularly review opportunities for reduction of mains water consumption.
- Install water efficient fittings and technology where economic and practical.
- Provide specifications and briefing documents for new developments aimed at low mains water consumption.
- Encourage use of recycled rainwater and grey water to reduce mains water consumption.
Imperial College water policy
The environmental effect of water use is becoming a central issue for the industry. A pragmatic method to address it, and consequently to mitigate climate change and reduce water consumption, involves setting ‘good practice’ and achievable targets. Targets are chosen to maintain flexibility and design freedom but strive to reduce overall water consumption whilst maintaining an excellent level of service.
While good design of water systems will reduce the amount of water used at Imperial College, the behaviour of the students and staff at the College will carry the most influence. Occupant education will therefore be a crucial factor in the reduction of water use.
The College will regularly monitor water use with frequent meter readings which will enable a rapid response to potential leaks in the system before damage, excessive use and expense occurs. Overnight leak tests by taking meter readings before and after a period of no occupancy will identify any leaks and/or overflows occurring in the building. The specification and design of all water systems will enable the management staff to monitor their systems, by remote means if appropriate.
Water consumption targets
The College will exceed the requirements of environmental legislation and advisory codes of practice where practicable and environmental benefit can be demonstrated and to achieve the following basic strategy:
- Reducing the unit cost of water.
- Reducing the volume of mains water used.
- Water Monitoring.
- Investigating its own sources.
The College has therefore set the following targets for its operations:
- Set a progressive target for water consumption.
- Reduce consumption by 25% by 2020 and 3 m3/person/year for offices.
- Provide a water metering strategy across the College which allows monitoring of water consumption to the required detail and accuracy.
- Apply regular comparison of building performance against published benchmarks.
- To ensure new development, upgrades and refurbishments are carried out to College policies, specifications and briefing documentation.
- Where possible apply independent environmental assessment methods (for example BREEAM) to new development.
- Consider schemes where use of water is generated by College sites.
