See-through manhole cover

Abstract

a The disclosure is directed to a manhole cover, comprising: an upper transparent disc; a lower transparent disc coupled to the upper disc; and means for emitting electromagnetic radiation at a predetermined wavelength that is narrower than full spectrum, the means for emitting electromagnetic radiation operably coupled to the lower disc, wherein: the upper disc has a diameter larger than the lower disc, and the predetermined wavelength is configured to inhibit vermin from inhabiting the volume irradiated by the means for emitting electromagnetic radiation.
