Jun 09, 2006. /Lesprom Network/. Potlatch Forest Products Corporation announced on Thursday, June 8 the expansion of SepticSure(TM) bathroom tissue into the Southeastern U.S. SepticSure is a unique tissue product that provides two-ply premium softness with rapid disintegration for households that are prone to sanitary system clogging. Such households include those with onsite septic systems, low flow flushing and RV/Marine sanitation systems. "The Southeast is an ideal geography for SepticSure," explains Bruce Woodlief, director of marketing for Potlatch consumer products. "Several states in this region have over 30% of households with onsite septic systems." According to the U.S. Environmental protection agency, nationally there are an estimated 25% of households that use onsite septic systems. Over 50% of onsite systems are over 30 years old. EPA's conservative estimates indicate that 10% to 20% of onsite systems have significant issues causing some level of system failure.(a) Potlatch Forest Products Corporation is a subsidiary of Potlatch Corporation, a real estate investment trust (REIT) with 1.5 million acres of forestland in Idaho, Minnesota, Arkansas and Oregon.
