Gle .~Hollowel ~l'~ol, IVy. l, assis~tit Director of Public Works Cit~f Coppell 7/32 Deforest Road ,/Coppell, Texas 75019 Re: Fire Hydrant Pressure Recorders First Week of Pressure Readings Dear Mr. Hollowell: As you requested, we deployed the six (6) fire hydrant pressure recorders at the locations listed below and shown on the attached meter location map on June 7, 2001: 1. Sandy Lake Road and Royal Lane 2. Anderson St. and Dillard 3. Wrangler and Enterprise 4. Bethal School Rd. and Rolling Hills 5. Kilbridge and Fallldrk 6. S.H 121 Bypass and Denton Tap Rd. On the June 14, 2001, the data was downloaded from the pressure recorders. Using the data, we have prepared the enclosed six charts illustrating the pressures encountered at the meter locations for your preliminary review and evaluation. Our next meter reading and meter relocation is scheduled for Thursday, June 21, 2001 at 6:30 a.m. This meter relocation will require the assistance of one City personnel to flush the hydrants prior to the installation of the pressure recorder. A representative of our firm will call to coordinate this assistance. We are available to discuss this project further at your convenience. icc..cl°sures Mr. Kenneth M.
