The marina wuter service feeds 350 hose bibs. AWWA methal (fixture count) shows a peak <br />flow rate of 158 gpm. AWWA recommended design capacity for a 2 inch displacement tne�er <br />(SO% of capacity) is 130 gpm (maximum capacity of the meter is l60 gpm). <br />One - 2 inch meter is marginally ovcr recommended capacity. <br />Two — 2 inch meters are more thau adequate. <br />One 4 inch meter is Vemendously over capacity (500 gpm) and is not warranted. <br />We suggest that one two inch meter is adequate because: <br />1) This is a"interini' meter scrvicc. The permanent meter scrvice and RPBA will bc <br />moved to a new location at a proposed marina service building in alwut 2 years (with the <br />new parking lot construction noted above). <br />2) Pressure head loss from the increased tlow rate is not a concern at this location. Static <br />pressures is I IS psi per GIS map. <br />3) If the design peak Flow rute is exceeded, the consequence is lower delivery rate at the <br />hose bibs for that limited perial of time. <br />4) Peak Ilow rate will probably only occur during warm days wlien people wash boats. <br />5) This solution and its limitations is acceptable to the owner (Per tel con with Dean <br />Shaughnessy 2/22/OS) <br />Two sets of revised drawings are attached. A third set with the revisions noted by yellow high lighting is <br />also included for your convenience. <br />Please inform us as to your decision on items 5 and 6 where we request modification of the revisions you <br />liste�. <br />Thank you for the quick review of the design and your patience as this design evolved. <br />��� � o�z 3� <br />H1UOC\?J\4P02\(NN) Pon of 8veren-Nonh Marina Bulkhead�!F7NAL DESIGMCortcspondcnceMcmo_Paul McKtt 022205.dx ` f <br />
