Abstract: Most commercial & residential buildings have rainwater collection systems that consist of leaders and gutters that collect water coming off the roof. These leaders and gutters are connected to drain pipes that channel the water away from the structure, usually into a dry well or storm drain. A substantial add-on to the leader and gutter system is a debris trap with an overflow port. The debris trap/overflow port may be attached to the leader at waist height (for easy access) to collect leaves, tree droppings, windblown litter and other materials. This debris can be easily discarded by opening an access panel to empty a built-in strainer. When a dry well or storm drain becomes saturated, water will back up through the leader causing seepage and overflow into the building and create erosion that can damage the foundation. The function of the overflow port is to divert water from the drain pipe away from the foundation.

Abstract: A water separating fuel filter is provided with a sensor at its bottom portion which is not removable in a direction away from the housing structure of the filter mechanism. In other words, if the sensor is removable at all, it must be removed in a direction which requires the sensor to move through the cavity of the housing structure of the filter while preventing an internal end of the sensor from passing in a direction away from the cavity and through a portion of the wall of the housing structure through which the sensor extends during operation. This eliminates the likelihood of a sensor being inadvertently removed from the housing structure and not properly replaced prior to subsequent operation of a fuel system of an internal combustion engine. This, in turn, prevents the condition wherein an opening at the bottom portion of the fuel filter housing structure can allow liquid fuel to flow from the fuel system into the bilge of a watercraft.

A layer of filter cloth can optionally be placed over the drain gravel. This device will be manufactured in variety of sizes and shapes and made from several different materials. The device has the unique ability of being capable of filtering low flow water runoff while allowing high volume to pass through with the added benefit of not retaining water that can become a mosquito breeding ground.
