ABSTRACT:
A system for reclaiming water which has been previously used for such purposes as washing vehicles includes both a diatomaceous earth filter for removing particulates and a carbon filter for removing organic contaminants. Reclaimed water which is in the system and not immediately required for use is continuously recycled by a pump so as to increase the removal of contaminants. A second pump moves the cleaned water into a pressure tank for use in washing. A substantial portion of the system is disposed below ground level with a lockable cover above.
