Abstract
Wastewater recycling is one of the criteria for continuous innovation at the campus level. Reclamation of water from the sewage system for gardening activities is one way to achieve this target at Universitas Pertamina. The aim of this study is to design and verify a water treatment unit from sewage to ready-to-use water for gardening activities. The units needed for the wastewater treatment system are a tank, Horizontal Roughing Filter (HRF), Rapid Sand Filtration (RSF), reservoir, and disinfection. The expected quality of effluent from processing is TDS 278 mg/L; TSS 1.3 mg/L; Turbidity 0.17 NTU; BOD5 0.63 mg/L; COD 6.12 mg/L; Total phosphate 0.95 mg/L; Nitrate 0.07 mg/L; detergent 0.7 mg/L; and total coliform MPN/100mL. The most important parameter in the sewerage water treatment process is the total coliform which must achieve an efficiency of 99%. This conventional method of water treatment is used because the availability of land is still sufficient, if it is not sufficient then further processing that is efficient, environmentally friendly, and has economic value is required.
Highlights
Green Campus is an environment-friendly system that involves campus residents in environmental activities, which must positively impact the environment (Tan et al, 2014; Widiastuti et al, 2019)

The largest concentration of each parameter will be used as the Wastewater Treatment Plant (WWTP) influent concentration. This aims to determine each unit's ability to treat the lowest quality waste to meet the quality standards of Government Regulation (PP) Number 22 of 2021 concerning Implementation of Environmental Protection and Management, water to watering plants need to be in class IV water quality
Summary
Green Campus is an environment-friendly system that involves campus residents in environmental activities, which must positively impact the environment (Tan et al, 2014; Widiastuti et al, 2019). Wastewater is one of the organic sources that contribute to greenhouse gases and nutrients in the waste, giving eutrophication impacts on water bodies (Sarwono et al, 2022; Sarwono et al, 2017; Sofiyah et al, 2021; Afifah et al, 2020). For this reason, water conservation optimization is needed in the form of wastewater reclamation activities by utilizing all water to archives zero waste in Universitas Pertamina. The drainage water discharge will be smaller with little rainfall intensity, and the quality will be worse with a high pollutant concentration in the dry season. Land conditions of the Complex of Universitas Pertamina buildings will affect the land availability used for WWTP design considerations
