Urbanization has catalyzed the rapid expansion of metropolitan areas through rural-to-urban migration. Consequently, as the population density increases and green open spaces diminish, optimal urban planning has emerged as a primary focus within the agrarian and land development sectors.

However, contemporary urban planning frequently encounters multifaceted challenges, particularly concerning water governance and wastewater management. Populations that exceed infrastructural capacities inevitably precipitate deficiencies in effective water management systems.

Consequently, issues such as waterlogging and water pollution—often stemming from inadequate pipelines and substandard management system performance—have become pervasive problems in major contemporary urban centers.

To investigate the root causes of these issues, a Civil Engineering student from Universitas Dian Nusantara (UNDIRA) conducted an evaluation and testing of the hydraulic pipe network at a prominent waterlogging-prone site: Jalan Pattimura–Prapanca Raya, South Jakarta.

The study focused on analyzing the condition and capacity of the hydraulic pipe network, aiming to optimize the existing wastewater pipeline infrastructure. In contrast to conventional residential pipes, hydraulic pipes are capable of operating under high pressures ranging from 20 to 100 MPa. Therefore, they exhibit substantial resilience against the elevated fluid pressures typically encountered in waterlogged areas.

The research was executed through systematic observation of the hydraulic pipe network's capacity to accommodate the design discharge, its compliance with hydraulic criteria, and the operational sustainability of the wastewater management system.

In the initial phase of the study, the UNDIRA Civil Engineering student utilized wastewater discharge analysis based on monthly recapitulations to determine the peak water discharge and flow rate, thereby establishing the design discharge. To ensure precise calculations, the student also measured variables including fluid pressure, flow velocity, fluid material characteristics, and pipe diameter.

Subsequently, an environmental topographic study was conducted to ascertain the existing surface conditions capable of influencing the gradient (elevation angle), soil structure, and soil quality. This study also accounted for surrounding features, such as road infrastructure and household utility channels adjacent to the pipeline route.

Utilizing contour data generated from field research and on-site soil property analysis, the student acquired a detailed monthly environmental recapitulation. Findings indicated that the full-flow water discharge in the Jalan Pattimura–Prapanca Raya area can reach 0.7296 m³/second, with a flow velocity of 1.15 m/second.

Supported by this empirical data, pipeline development can proceed in accordance with Detailed Engineering Design (DED) principles. This ensures that the construction of the 250 mm diameter pipeline is resilient against Point Bearing shifts while effectively managing the existing wastewater around Jalan Pattimura–Prapanca Raya. The proposed pipeline network is designed to support an operational velocity of up to 1.40 m/second, thereby fulfilling the design velocity criteria (ranging from 0.3 to 0.6 m/second), whilst maintaining a residual storage capacity of 20% of the existing wastewater discharge.

The enhancement of the existing wastewater pipeline by the Civil Engineering student from Universitas Dian Nusantara (UNDIRA) represents a concrete implementation of sustainable ecosystem monitoring and metropolitan strategic development. Furthermore, it serves as a preventive measure against future escalations in wastewater discharge volumes.

Ultimately, this study demonstrates that the Civil Engineering Study Program at UNDIRA remains steadfast in its vision and mission to advance construction through sustainable innovation and metropolitan engineering. This initiative not only provides a creative intervention but also fundamentally supports the development of solution-oriented urban planning for the future.
