Frequent flooding at the TUP Manila Campus, even during light rainfall, raises
significant concerns. This study evaluates the campus drainage system to assess its
capacity, identify deficiencies, and propose flood resilience improvements. A topographic
survey and hydraulic analysis using Manning’s Equation and the Rational Method were
conducted for five catchment areas. Results show the drainage system meets discharge
capacity requirements for 25-year and 100-year return periods, with capacities ranging
from 0.050 to 0.214 m3/s. However, localized flooding persists due to blockages, increased
urbanization, insufficient green spaces, and poorly planned drainage connections.
Contributing factors include debris buildup, limited manholes, inadequate pipe diameters,
and capacity constraints of Estero de Balete, compounded by upstream runoff and climate
change. Data from Project NOAH suggests that during a 100-year return period,
cumulative rainfall and topographic conditions could result in campus submersion.
Findings highlight the need for regular maintenance, infrastructure upgrades, and holistic
flood mitigation strategies. Key recommendations include increasing pipe diameters,
improving maintenance practices, adding manholes and catch basins, addressing Estero de
Balete’s limitations, and promoting sustainable urban planning. These measures aim to
enhance campus flood resilience, support sustainable water management, and align with
broader urban flood mitigation efforts.
