Benefits of technology

[0004] More particularly, according to the present invention a sewer drainage system includes an under ground water drain off region, a ground level opening to a down passage to the drain off region, a sewer grate across the ground level opening and an insect block in the down passage below the sewer grate. The insect block inhibits insects such as mosquitoes and the like from gaining access to the drain off region while permitting flow of water through the system.

Problems solved by technology

West Nile disease, which is a disease transmitted by mosquitoes is becoming an ever increasing threat.
As will be understood the particular problem presented by storm sewers is that they are generally located in highly populated locations where people are easily accessible to mosquito bites.

Embodiment Construction

[0013] FIG. 1 shows a sewer drainage system generally indicated at 1 according to a first preferred embodiment of the present invention. This system incorporates features of known storm sewer systems which are typically found in a roadway 7 bordered by a sidewalk 3 and a curb 5. The system shown in FIG. 1 includes a sewer grate 9 held in position by a grate frame 11 over a down passage 13 which leads to a water run off region defined by sewer drain pipe 15. In many instances, the drain pipe will not completely clear leaving a small puddling of water 17 in the drain pipe. Over extended periods of time when there is no rainfall this water has the potential of becoming a stagnant breeding area for bugs such as mosquitoes and the like.

[0014] FIG. 2 of the drawings shows that system 1 according to the present invention further includes an insect block generally indicated at 21. When there is no water flowing into the system the block 21 assumes a blocking position within the down passage...

Abstract

A water sewer drainage system particularly directed to prevent spread of West Nile disease includes an underground water drain off region, a ground level opening to a down passage to the drain off region, a sewer grate across the ground level opening and an insect block in the down passage below the sewer grate. The insect block inhibits insects from gaining access to the drain off region while permitting flow of water through the system.

Description

[0001] The present invention relates to a water sewer drainage system including an insect block to inhibit insects such as mosquitoes and the like from gaining access to the drain off region of the system which may at different times contain trapped stagnant water.[0002] West Nile disease, which is a disease transmitted by mosquitoes is becoming an ever increasing threat. Mosquitoes typically inhabit stagnant water. One such potential area i.e., habitation ground for the mosquito infestation is within a storm sewer where non-running water will collect beneath ground surface. This non-running water then provides a stagnant breeding ground for mosquitoes. As will be understood the particular problem presented by storm sewers is that they are generally located in highly populated locations where people are easily accessible to mosquito bites.SUMMARY OF THE PRESENT INVENTION[0003] The present invention provides a sewer drainage system specifically designed to inhibit mosquitoes populati...
