Efficient Horizontal Drain System for Levee Protection and Seepage Control

The Horizontal Drain system aims to capture seepage water to keep embankments dry and provide added protection against structural failures. This comprehensive system operates under the jurisdiction of both USACE and LACDPW. With a design featuring 72" diameter R.C. pipes and strategically placed 4" perforated pipes, the drain spans 2600 feet along the levee basin. Installation utilizes trenchless methods, ensuring minimal disruption and low maintenance costs, estimated at $141,300. This innovative solution is crucial for areas prone to seepage issues.
