The SludgeHammer® unit is installed into your existing septic tank! No heavy equipment is required and there is very little disruption to your landscaping and none to your existing drainfield. The S46 system runs on less than 60 watts of power, that is only pennies day. It’s easy to maintain and your SludgeHammer® installer will set you up on a schedule for an annual check up to make sure your system is working properly. A typical SludgeHammer® installation costs for less than replacing your current leach field and will save you thousands of dollars.
