Extremely High

Total water withdrawal (potable and non-potable combined):
Performance Year Baseline Year
Total water withdrawal 600,494.35 Cubic Metres 858,725.02 Cubic Metres

Potable water use:
Performance Year Baseline Year
Potable water use 600,494.35 Cubic Metres 858,725.02 Cubic Metres

Start and end dates of the performance year and baseline year (or three-year periods):
Start Date End Date
Performance Period Jan. 1, 2021 Dec. 31, 2021
Baseline Period Jan. 1, 2018 Dec. 31, 2018

A brief description of when and why the water use baseline was adopted:

Please note that the total nonpotable water withdrawal cannot be calculated. Only potable water is recorded. Thus we assumed that the nonpotable value id zero for both the baseline and the performance year.

A brief description of the institution's water-related behavior change initiatives:

Every year during the semester breaks, holidays, and summer break, the College initiates system-wide the water-saving program that covers the following points in an attempt to save and conserve potable water:
* Switch OFF all water features and swimming pools
* Close the domestic water supply in unoccupied areas, as appropriate.
* Monitor the water pump operations and check all areas for water leakage, report immediately and rectify to avoid water wastage.
* Cleaners should use the air-mixed water pressure pump for washing and cleaning.
* Irrigation water supply should be set for the plants only in the early morning, evening, and nighttime.
* Need to check all the drippers and Sprinklers during the timing of water.
* supply to the concerned area to avoid leakage and wastage of irrigation water.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

Over 2020 / 21 there were several water management projects implemented at various HCT campuses and buildings:
• Fixing of Aerators for all taps in the washbasins system-wide: The replacement of ordinary aerators with water savings ones (869 Nos.), fixing of flow restrictors at hand spray, ablution areas, and showers (194 Nos.) and inserting additional bottles filled with water in cisterns (185 Nos.) across various campuses have achieved an average savings of 38 % of domestic water per year.
• Fixing of flow restrictors at hand spray, ablution areas, showers – ADW
• Irrigation Network Upgradation AAM: A smart irrigation system using soil humidity sensors, water gauges, and timers connected automatically to automatic sprinklers to ensure efficient and effective grass watering has been executed in one of the campuses achieving water savings of 14,000 M3.
• Various campus water management initiatives (awareness campaigns, cleaning practices, etc.).
• An MOU has been signed between Federal Electricity and Water Authority (FEWA) and HCT to initiate utilities consumption reduction strategy via conservation and awareness campaigns, installation of water tabs aerators, exchanging information supporting sustainable development, utilizing students' sustainable projects related to solar power and green energy, technical support and consultancy in relation to green buildings, and Provision of Awareness Training Sessions for the cleaning team. As a result of MOU, a reduction of the MOU, a reduction of water consumption of 12 % has been achieved in the last 2 years.
