High Performance Solution to Your Wastewater Problems


Can your old septic system remove up to 99 percent of wastewater contaminants before it discharges into your water supply and general environment? If you don’t think so, have Dunham's Contracting (2009) Ltd give you an on-site assessment and free estimate for an innovative and cost-effective System O)) Septic Systems. When you install System O)) Septic at your home or business, you are gaining a wastewater treatment system that takes up less space and outperforms a conventional leaching system, even on sloping sites. Using components made of recycled plastic that last indefinitely, System O)) Septic doesn’t need a maintenance contract.
