A silt guard apparatus for filtering runoff water, including a fluid distributing pan coupled to a silt guard or filtering device. The silt guard apparatus is fitted over and seated upon a drainage pipe for controlling erosion at construction sites and for trapping and preventing oily residues and/or solid particles such as silt and other debris from being washed into, collected or being otherwise deposited within a water drainage pipe with the runoff water, while still enabling water to drain therethrough. The fluid distributing pan of the present invention includes an orifice, and may further include a fluid receiving body surrounding the orifice and a connecting member contiguous with the fluid receiving body. The connecting member functions to couple the silt guard to the fluid distributing pan to form the silt-guard apparatus, which in another embodiment is interconnected and substantially sealed to the drainage pipe.

1. A silt guard apparatus for filtering solid particles and/or oily residues from a flow of water into a drainage pipe, the apparatus comprising:a fluid distributing pan having a fluid distributing orifice, the orifice being in fluid communication with the drainage pipe, wherein the fluid distributing pan fits over and seats upon the drainage pipe and the fluid distributing pan being removably mountable to the drainage pipe; a silt guard coupled to the fluid distributing pan opposite the drainage pipe, wherein the silt guard has a body portion, a top portion and a filter; the body portion being in fluid communication with the orifice and the body portion having an open lower end attached to the fluid distributing pan, a spaced upper end, and a series of ribs extending between the upper and lower ends and defining passages therebetween in fluid communication with the fluid distributing orifice; the top portion extending upwardly from the body portion; and the filter received over and supported by the top portion and overlapping the body portion for filtering solid particles and/or oily residues from the water passing therethrough and into the drainage pipe, the filter being formed from a porous filtering material.
