The Pollardwater Prime Ultra-Grease Block can help rid a water source of organic fats, oils and grease. This safe product is filled with bacteria that, when lowered into contaminated water sources, slowly and continuously dissolves and digests waste in lift stations and wet wells. In addition to combatting the costs of major grease disposal, it offers timesaving benefits thanks to its easy-to-use design. Simply use the included hanging rope to lower the block into contaminated water and let it sit across from high-flow areas for 30 to 90 days. It is available in three sizes and weights, from as little as 5 pounds for lesser amounts of waste accumulation to as much as 30 pounds for higher, more detrimental waste buildup. 800-437-1146; www.pollardwater.com.
