With regard to your letter concerning the effects of the "Y2K" phenomenon, it is our belief that the sewer lines we installed at your facility will continue to function in spite of any chronological tracking system's arbitrary recognition of any particular day, including but not limited to January 1, 2000, albeit, the Gregorian, ecclesiastical, or even the obscure Stonehenge-based Druidic Calendar.

However, should the sun's rise or setting on any day affect the Newtonian laws of physics with regards to the gravitational fields, then not only will we all either fly off into space, or be crushed into the Earth with unimaginable pressure, but the contents of the sewer main and the mains themselves will also be subjected to the same fate, or maybe not.
