Operating pressure is in the range of 15-22 psi. I also got some <br />feedback from Maintenance and they asked that both a check and isolation valve (gate or plug) be provided at the 6" FM <br />connection to the SEI. <br />Thanks, <br />CELEBRATING Amie Roshak, P.E. <br />12� Associate Engineer I Public Works - Utilities Engineering <br />) Y E A R S 425.257.7249 13200 Cedar St., Everett, WA 98201 <br />A story worth telling everettwa.eov/oublicworks I Facebook I Twitter <br />Note: Emails and attachments sent to and from the City of Everett are public records and may be subject to disclosure pursuant to the Public <br />Records Act. <br />From: Ray Johnson <rayj@sittshill.com> <br />Sent: Thursday, February 21, 2019 3:40 PM <br />To: Amie Roshak <ARoshak@everettwa.gov> <br />Cc: Sabrina Fandler <SFandler@everettwa.gov>; David Fillmore <davidf@sittshill.com>; Kathy Hargrave <br /><kathyh@sittshill.com> <br />Subject: Connection to the existing 48 inch South End Interceptor <br />Based upon the asbuilt civil drawings for the South End Interceptor, we assume that this pipe is pressurized based upon <br />the manhole's flanged riser. Please verify. We were directed to connect our forcemain crossing the 80 utility easement <br />to the capped DI spool located on top of interceptor. If this interceptor is pressurized, we need to understand what that <br />is in order to design the 6" DI connection and the Penske onsite temporary sanitary sewer forcemain system. <br />Ray Johnson, A.S.L.A. ■ Project AUJanager <br />srm i HILL M61NEEfRi, INC. <br />CM& • STPAXtuRK ■ suRVITM <br />4815 CENTER STREET `ACOMA, WA 98409 <br />PHONE: 253-4;4.9449 FAX: 253 4'4-0153 <br />httu:l/www.sitts-hill-engineers.com/ <br />SITTS & HILL ENGINEERS, INC. <br />TACOMA, WASHINGTON <br />1 <br />
