Stormwater Management Technology Integrated with Architecture
This lecture, delivered to undergraduate landscape architecture students in LAN 381 at KMUTT, explored how buildings function as hydrological infrastructure and how stormwater can be captured, treated, stored, and reused rather than simply discharged. Topics covered included the role of roof type and material in determining runoff volume and water quality, catchment area calculations, first flush diversion, conveyance design, and cistern sizing and placement. The lecture also introduced frameworks such as Low Impact Development (LID), ABC Waters, and Artful Rainwater Design as guiding approaches for integrating water management into the built environment.
The second half of the lecture focused on translating these concepts into constructible systems and construction drawings. Students learned what a complete stormwater harvesting drawing set must include, from catchment diagrams and conveyance details to overflow routing, filtration, storage sections, and maintenance specifications. The session concluded with a discussion of common design pitfalls and the importance of early coordination between architectural, landscape, and civil disciplines to ensure that stormwater systems perform as intended.
