Ina Road landfill stormwater management system design

Abstract

This report describes the design of the Ina Road Landfill Stormwater Management System. Such a system is required by the Arizona Department of Environmental Quality to efficiently and safely remove stormwater drainage from the landfill to better protect the environment and the public during storm events. Stormwater drainage systems are required at landfills to efficiently collect and remove stormwater, limit moisture that can penetrate waste, protect the integrity of the buried mass and the final cover system from washing out and reduce risk of flooding to neighboring property. The State requires that landfill stormwater management systems be designed to handle a minimum size storm event based on historical precipitation records.
