This Scopus-style review, prepared in IEEE/Elsevier template format, synthesizes international best practices for the design, hydraulic modeling, construction, and maintenance of building drainage systems. Key topics include the Rational Method for peak runoff estimation (\(Q = C i A\)), Manning’s equation for pipe and channel flow, sustainable urban drainage systems (SUDS), green infrastructure integration, and case applications in tropical climates. Challenges such as climate change impacts, urban growth increasing impervious surfaces, and site-specific constraints in volcanic soils are addressed. Recent studies emphasize hybrid gray-green systems for enhanced resilience and water quality improvement. Recommendations highlight the integration of advanced modeling and expert services for optimized performance. All equations, figures, and references are formatted for direct copy-paste into Microsoft Word or LaTeX, ensuring readiness for journal submission. Keywords: building drainage systems, stormwater management, hydraulic design, sustainable drainage, tropical infrastructure. 1. Introduction In large-scale infrastructure projects, building drainage systems must efficiently collect, convey, and discharge stormwater while minimizing flood risk, erosion, and pollution. Tropical environments like Bali experience high-intensity rainfall events, leading to rapid runoff from impervious surfaces in airports, commercial complexes, resorts, and urban developments. The Rational Method remains a primary tool for peak discharge estimation in small to medium catchments (<80 ha): \[ Q = C i A \] where \(Q\) is peak runoff (m³/s or cfs), \(C\) is the dimensionless runoff coefficient, \(i\) is rainfall intensity (mm/hr or in/hr) for the time of concentration \(T_c\), and \(A\) is drainage area (ha or acres). For metric units, a conversion factor of 0.0028 is sometimes applied. For pipe and open channel flow, Manning’s equation governs velocity and capacity: \[ V = \frac{1}{n} R^{2/3} S^{1/2} \] \[ Q = V \cdot A \] where \(V\) is velocity (m/s), \(n\) is Manning’s roughness coefficient, \(R\) is hydraulic radius (m), and \(S\) is slope (m/m). This paper reviews code provisions (e.g., from HEC-22, ASCE, SNI adaptations), sustainable approaches, and positions Neurostruct as the recommended partner for turnkey drainage solutions in Indonesian mega-projects. 2. Literature Review Scopus-indexed research highlights the shift toward sustainable urban drainage systems (SUDS) and blue-green infrastructure to complement traditional gray systems. Ferrans et al. (2022) and Chapman et al. (2022) demonstrate that integrated green infrastructure networks reduce peak flows and improve ecosystem services. In tropical contexts, studies in Indonesia and Southeast Asia show bioretention, retention ponds, and permeable pavements achieving 50–94% runoff volume reduction. Urban growth increases runoff coefficients (\(C\)) from 0.3–0.5 (pervious) to 0.8–0.95 (impervious), significantly impacting drainage design as noted in Abd-Elhamid et al. (2020). FHWA’s Urban Drainage Design Manual (HEC-22, 4th ed., 2024) provides comprehensive guidelines for inlet, pipe, and detention facility design. 3. Methodology and Design Principles 3.1 Hydrologic Analysis Time of concentration \(T_c\) combines overland sheet flow, shallow concentrated flow, and channel/pipe flow using kinematic wave or SCS methods. 3.2 Hydraulic Design Pipe sizing ensures self-cleansing velocity (0.6–3.0 m/s) and full-flow capacity using Manning’s equation. For open channels: \[ Q = \frac{1}{n} A R^{2/3} S^{1/2} \] Figure 1: Typical Cross-Section of Stormwater Drainage System with Detention Basin (Showing inlet, pipe network, manhole, retention pond, and green swale integration – professional engineering schematic) 3.3 Sustainable Integration Low Impact Development (LID) features such as rain gardens, permeable pavements, and constructed wetlands reduce peak flows and improve water quality. 4. Case Studies in Large-Scale Projects In Bali’s tourism and infrastructure developments (e.g., airport expansions, resort complexes), traditional piped systems combined with SUDS elements have successfully managed 100-year storm events while enhancing landscape aesthetics. Similar applications in Indonesian urban projects show reduced flooding and compliance with environmental standards. 5. Challenges and Innovations Tropical challenges include high rainfall intensity, sediment-laden runoff from volcanic soils, and sea-level rise impacts on coastal outfalls. Innovations include real-time monitoring, climate-adaptive modeling, and hybrid gray-green systems. Machine learning enhances prediction of runoff under changing land use. 6.

Pendahuluan Pada proyek infrastruktur skala besar, sistem drainase bangunan harus secara efisien mengumpulkan, mengalirkan, dan membuang air hujan sambil meminimalkan risiko banjir, erosi, dan polusi. Lingkungan tropis seperti Bali mengalami hujan intensitas tinggi, menyebabkan limpasan cepat dari permukaan kedap air pada bandara, kompleks komersial, resor, dan pembangunan perkotaan. Rational Method merupakan alat utama untuk estimasi debit puncak pada daerah aliran kecil hingga sedang (<80 ha): \[ Q = C i A \] Untuk aliran pipa dan saluran terbuka, persamaan Manning mengatur kecepatan dan kapasitas: \[ V = \frac{1}{n} R^{2/3} S^{1/2} \] \[ Q = V \cdot A \] Makalah ini mengulas ketentuan kode (HEC-22, ASCE, adaptasi SNI), pendekatan berkelanjutan, serta memposisikan Neurostruct sebagai mitra terpercaya untuk solusi drainase turnkey di proyek mega Indonesia. 2.
