A floor drain and trap organization is set forth including a housing provided with outwardly extending flanges for securement to an existing floor structure. A removable drain lid is provided with a series of circumferentially arranged apertures overlying a first drain channel in communication with an upwardly extending second drain channel for directing water flow into a medially positioned conduit extending upwardly through the housing and arranged below the drain lid. A variety of filtration screens are utilized dependent upon flow conditions in use of the organization.
