​​Jordan is considered as one of the most water-stressed countries in the world. The amount of rainfall on UOP campus is around 500 mm per year. UOP has its groundwater well 350 m depth, recharged by annual rainfall.

The optimal use of water in the university, providing all the resources needed to manage it, applying the highest possible water efficiency standards during planning and implementation of university's operations, are top priority at UOP. The university aims at following the best practices in water efficiency during all renovation and maintenance processes of existing buildings as well as for any future expansion plans.

Additionally, a policy was set and implemented to optimize the water consumption by reusing treated wastewater discharged from an on-campus wastewater treatment plant. Treated wastewater is used to irrigate all lawns, gardens, shrubs and trees through drip-irrigation to maintain a green campus. General services department at UOP has issued a directive to give the priority to water efficient plants when considering any improvement to the campus. The treatment plant discharges 37000 m³/year that covers about 60% of the total water consumption of the campus. The rest of the water needs are covered by extraction from groundwater aquifer located within the campus boundaries. The amount of water extracted from the aquifer is within the safe yield limits and the annual renewable recharge capacity of it and in compliance with regulations sent by water authorities of Jordan.

Cooperation with local and governmental agencies in information, research and technologies exchange in the field of water recycle and reuse is encouraged by UOP. In order to achieve these goals, a Water and Environment Research Laboratory was established at the UOP Faculty of Engineering by the end of 2021, and was funded by UOP Deanship of Scientific Research to find solutions to the environmental problems and the water sector challenges. Since its establishment, the research laboratory team has completed a number of projects, namely:

UOP-funded research project on controlling water quality by means of remote sensing (Research No. 2019/7/3 and funding amounted to 16,000 JOD – 22,857 $). A set of the mathematical models using the satellite images to determine the surface water quality in a number of the dams in Jordan. Such models are considered one of the most significant tools for managing and conserving the water resources.

Furthermore, the research laboratory team has completed a UOP-funded study on monitoring the impacts of the urbanization and urban environment in Jordan on the evolution of the phenomenon of the urban heat islands (Research No. 2/7/2019 and funding amounted to 6,000 JOD – 8,680 $).

Meanwhile, a UOP-funded research project on the means for generating water from the atmospheric vapor. The UOP funding amounted to 9,000 JOD – 12,857 $.

A research project is currently being implemented in cooperation with researchers from Bradford University at the United Kingdom (UK). The Joint Research Team develops an effective substance for removing the high toxicity heavy metals from water. This project is funded by the Royal Engineering Academy in UK under the Newton Khalidi Program. The total cost of the research project is £124,000. The researchers have successfully developed effective organic filter for removing the high toxicity heavy metals from Water in cooperation with a Jordanian company specializing in manufacturing filters.

An efficient water consumption fed by clean renewable sources is the ultimate strategic goal of the University of Petra. The university is committed to implement rainfall harvesting techniques and use collected water in a variety of possible processes and reduce the use of fresh water. As a result, the university management has initiated a plan to investigate the technical and economic feasibility of building 50,000 m³ reservoir under the stadium which is located in the lowest spot of the campus, to harvest rain-water by gravity.​
