So we should buy stock in Noble? glc -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Todd Williams - FPDC Sent: Tuesday, September 30, 2008 7:49 AM To: [email protected] Subject: RE: Alternate to pitch?
The existing systems are all OH pipe schedule (with 3/4" pipe) and the vacant building would be LH. The other consideration is that they currently have two 1500 gpm pumps taking suction from a pond and part of the program would be to connect it to the public supply. Hydraulics and other factors would be taken into consideration, but the pitch issue is the most complicated. Besides, with 1,500,000 sqsft of pipe network, we'd have to bring in anti-freeze in tank cars....
