The park I manage owns the sewer system. Through the foreclosure, poor management and WI DNR regulations we’ve ended up in a poor situation. All of out sewer goes to holding tanks and then we pay someone to pump it. It’s a losing proposition to say the least, we’re spending over $1000/mo for about 12 tenants. Every time the pumper shows up he’s grinning and I get a belly ache. We got a quote to install a mound system, the company figured $150,000. For clarification a mound system is a standard septic system/ leach field, except where we are it’s heavy clay and we have to haul in the sand for the water to percolate. We own 12 acres across the road so we could go this route but the cost seems a little unrealistic. Any other systems or processes we should entertain?
