Universitas Pertamina uses automatic pressure-control technology to regulate groundwater extraction according to demand at campus ablution facilities. A groundwater pump equipped with an automatic pressure controller responds to demand within the connected water-supply system, helping avoid continuous pumping when water is not required. Rainwater infiltration wells and biopore infiltration holes complement this arrangement by facilitating rainwater infiltration and supporting local groundwater recharge.
The municipal water network remains the main water source at Universitas Pertamina. The groundwater installation supplies water for wudu at campus ablution facilities.

Groundwater Extraction

Groundwater is drawn directly from a well using a multistage centrifugal pump equipped with automatic pressure control (APC). The extracted water flows through a pipeline to the ablution taps. Approximately 5 m³ of groundwater per day is estimated to be pumped and used at these facilities.
The APC automatically controls pump operation in response to pressure changes associated with water demand. Because the pump draws water directly from the well, this arrangement provides operational control at the point of extraction and helps avoid unnecessary continuous pumping.
An integrated pressure gauge provides a visual indication of operating pressure, allowing the pumping system to be checked during inspection.

The supply arrangement connects the groundwater well to the extraction pump and then to the ablution facilities. The schematic illustrates the water source, pump, automatic controller, and point of use.

Groundwater Recharge through Infiltration Wells and Biopores

As part of responsible and sustainable groundwater management, Universitas Pertamina undertook extensive installation of biopore infiltration holes and rainwater infiltration wells in 2023 throughout Universitas Pertamina and the Pertamina Simprug Complex. These wells collect rainwater and allow gradual infiltration into the surrounding ground. They provide infiltration space within the developed campus environment, helping reduce direct surface runoff and supporting local groundwater recharge.

Biopore infiltration holes are also present in landscaped areas at Universitas Pertamina, including marked installations near buildings and pedestrian routes. These installations provide additional pathways for rainwater to enter the soil and complement the infiltration wells in managing surface runoff.

Automatic pump control, infiltration wells, and biopores serve complementary purposes. The APC regulates groundwater pumping according to demand, while infiltration wells and biopores facilitate the return of rainwater to the ground. Together, these measures form part of Universitas Pertamina’s approach to responsible groundwater extraction and groundwater recharge through rainwater infiltration.
