Optimization Of Storm Water Harvester

Abstract

Amongst many practices in water conservation, harvesting is one of the best practices. It helps to check depleting water table. Whereas rooftop harvesting is a simple task, storm water harvester often faces maintenance issues. Clogging of the storm water harvester is a limitation of these trenches. Clogging time can be enhanced by specially designing these trenches. We can further address the maintenance issue by increasing the plan area of the harvester. It helps in physical treatment of water and reduces the TDS in water. Harvesters with different configurations were tried and optimization was done for filter media and design of the harvester.  If two harvesting units are joined at the top, it increases the clogging time exponentially. Further a simple solution of replacing the top 50 cm of sand in the filtration media can make them operational again.
