Open-Source Project Overview: Modular Recycled-Plastic Water Channels Project Summary Project Name: OpenHydro Channels (Modular Community Water Routing System) License: Creative Commons Attribution-ShareAlike 4.0 International (CC-BY-SA 4.0) / CERN Open Hardware License Core Mission: Provide accessible, decentralized water conveyance and drainage infrastructure to underserved areas using 100% recycled waste polymers and open-source additive manufacturing. Intended Use: Low-pressure surface irrigation, hillside stormwater redirection, community drainage, and greywater management. System Architecture & Design Features Raw Material Feedstock: Sourced from post-consumer mixed polymers, low-grade warehouse stockpiles (Types 3–7), and ocean waste plastic. Formulated for direct pellet-extrusion large-format 3D printing (FGF - Fused Granular Fabrication) to bypass costly filament production. Modular Interlocking Mechanics: Lego-Style Geometry: Standardized male/female interlocking joints designed for tool-free, friction-fit hand assembly. Snap-Fit Access Lids: Tupperware-style press-on top covers allowing rapid maintenance, sediment cleanout, and inspection. Integrated Surface Filtration: Surface mounts engineered to hold standard black woven silt fencing, blocking debris and fine soil before water enters the channel. Topography-Adaptive Slicing Workflow: Leverages open-source GIS elevation and digital elevation model (DEM) data to map local terrain contours. Generates sequentially numbered print runs with custom slope-compensated joints to guarantee gravity-driven flow over uneven ground. Open Technical Challenges & Collaborative Needs Software Development: Automated parametric script to convert 2D/3D topological terrain plots directly into segmented STL/G-code print runs. Polymer Formulation: Testing UV stabilization additives and determining ideal thermal profiles for mixed/contaminated recycled plastic pellets. Hydraulic Benchmarking: Flow rate validation, joint water-tightness under sediment loading, and compressive ground-load testing. Community Deployment Model Decentralized Production: Blueprints and print files are distributed freely for local fabrication using regional or mobile pellet-extrusion printers. Volunteer-Friendly Assembly: Numbered modular pieces enable rapid, community-led installation with zero heavy equipment or specialized tools required. Defensive Public Disclosure: Open publication establishes prior art, ensuring this design remains permanently free and unencumbered by private commercial patents. 2600:387:F:5533:0:0:0:7 07:36, 16 August 2026 (UTC)Reply
