Salt Brine Facts

Safety-Environmental-Economical

• Islip was the first township in Suffolk County to successfully use salt brine as a snow fighting tool. Last winter season, 2009/2010, we installed a brine making facility in the Bay Shore Highway yard. We retrofitted two late model street sweepers that were not repairable and converted them into Brine Spreading trucks. These two trucks and a 4 wheel drive Epoch truck were used successfully to spread Brine. This year, we added another brine making facility at the Sayville Highway yard and a holding tank in Hauppauge. In addition, we retrofitted another vehicle and added 4- 4x4 F-350- pickups with brine spreading capabilities to handle cul de sacs and dead ends. This year we will have 8 brine spreading vehicles to handle the over 1200 miles of roads in Islip.

• What is salt brine? Salt brine is rock salt, which is already used as a melting agent, and water in a 23.3% solution. When applied to the road surface the water evaporates leaving behind a coating of salt creating the barrier between the road surface and snow.

• Solution of 23.3% yields lowest melting temperature (sea water 7-8%)

• Pro-active approach to snow and ice control offering a high level of service meaning cleaner and safer roads.

• Fiscally sound. Anti-Icing done on straight time when possible by 18-24 hour advanced application. Calcium chloride cost is about $3.00/gal. Brine approximately $0.08 to $0.15 per gal.

• Ecologically sound less harmful than other chemicals being applied and getting into storm drain system and drinking water supply.

• Anti- Icing: done prior to storm prevents chemical bond from occurring between road surface and snow pack.

• Pre-Wetting: Application of brine to rock salt as it is applied to road surface which activates the salt for quicker melting of snow and continues to aid in the barrier between snow and road surface.

• More efficient plowing operation due to the fact that snow is less likely to stick to the surface.

• When used in conjunction with Epoch Spreader, slurry is created by having a finer salt particle to saturate at 30% making the slurry stick to the surface and not having the bounce and scatter of standard wetting systems. This also allows for a savings in salt usage, 30-40%, and increases the coverage traveled by the applying vehicle.

• Application rates are normally 30-40 gallons per lane mile.

• Bay Shores Brine maker produces 5,000 gallons per hour. With the addition of the Brine maker in Sayville, we will be able to produce over 10,000 gallons an hour and store over 4,500 gallons at our remote site in Hauppauge.
