Marathon Water supply Plan Tank FarmsFIRE WATER DEMANDS All storage tanks on site are 120 ft diameter internal floating roof tanks. Fire water demands are as follows: • Seal fire - 425 GPM including 20% wastage (9,543 gal) • Full surface fire - 2,200 GPM including 20% wastage (143,000 gal) WATER SOURCES • City of Cottage Grove water system - Flow capacities as of August 2010: • East 18th St. (in front of facility) - 1,600 GPM @ 20 psi • Grange Blvd /Hadley Ave. South - 12,000 GPM @ 20 psi (Fire Station No. 1) • Lake at intersection of Grange Blvd /Hadley Ave. South • 1,034,000 gal. /l ft of depth (estimated) PLAN • Seal fires and misc. fires on site: (Demand of 1,600 GPM or less): • Utilize hose lays from hydrants along East 18th St. in front of facility. • Consider staging resources for or implementing a high volume option if significant potential for fire escalation. • Full surface tank fire: • Utilize hose lays from hydrants along East 18th St. in front of facility for exposure protection and misc. purposes while full volume supply is established. Note This water supply may need to be discontinued or restricted in order to achieve full capacity of High Volume Option A. • Implement High Volume Option A or B depending upon conditions and available resources. Consider: • Staging spare pumpers along hose route in event of a mechanical breakdown. • Staging spare hose or laying redundant hose lines along hose route in event of a hose failure. • Greater fire flow demands can be achieved by: • Simultaneously implementing High Volume Options A and B. • Increasing the number of hose lines used in either High Volume Option A or B.

Connect all outlets of the hydrants to the pump suctions and charge hydrant. • Rating of each primary pumper must be equal to or greater than that recommended in Table 1. • Set up Hose Lay 1 from primary pumpers along route shown. Size, quantity and maximum length to be in accordance with Table 1. Minimizes bends and kinks in hose lines. • Minimize fittings and adapters in relay hose lines. If fitting loss exceeds 20 psi shorten hose lay. Set up Supplemental Hose Lays • Place supplemental pumpers at hydrants shown and connect to hydrants using the largest diameter & shortest length hose(s) practical. Connect all outlets of the hydrants to the pump suctions and charge hydrant. • Rating of each primary pumper must be equal to or greater than that recommended in Table 1. • Set up Supplemental Hose Lays between supplemental pumpers and primary pumpers as shown. Size, quantity and maximum length to be in accordance with Table 1. Minimizes bends and kinks in hose lines. • Supplemental hose lines to be connected to an LDH suction inlet of primary pum- per to be fed. • Minimize fittings and adapters in relay hose lines. If fitting loss exceeds 20 psi shorten hose lay. • Set up Hose lay 2 • Place relay pumpers at end of Hose Lay 1. • Rating of each relay pumper must be equal to or greater than that recommended in Table 1. • Set up Hose Lay 2 from relay pumpers along route shown. Size, quantity and maximum length to be in accordance with Table 1. • Minimize fittings and adapters in hose lines. If fitting loss exceeds 20 psi shorten hose lay. Set up successive hose lays as described for Hose Lay 2. Start and operate hose relay: • Slowly charge all hose lays and bring each primary and relay pumper up to the discharge pressures recommended in Table 1. • Adjust discharge pressure of supplemental pumpers as needed to maintain suction pressure of the primary pumper supplied at 20 psi or greater. • Verify flow rate obtained and adjust relay as needed to reach flow rate. • Once flow capacity is confirmed proceed with foam fire attack.
