Abstract
Cost-Effective Wastewater Planning: Integrating GIS and HYDRA with Custom-Scripted Programs
Track: Water Distribution, Wastewater, and Stormwater
Author(s): Marcel Dulay, Sanaan Lair
A wastewater planning project for Nuevo Laredo, Mexico, funded by U.S. EPA, was conducted to rehabilitate sewer collectors and provide for future growth. GIS was used for City-wide utility mapping, various land use analyses, digital elevation modeling, and managing both spatial database sets and physical inspection data. To create a hydraulic model, custom-scripted programs written for ArcView were used to interface spatial information with HYDRA. HYDRA is a low-cost, effective modeling tool with limited database editing features. This novel approach allows the use of HYDRA in wastewater planning for projects with extensive data sets, which previously could not be done efficiently.
