Added to the list of Jason items at the WWTP. This is part of the “Do you get it now?” conversation. Only defense is we didn’t until just recently have the money to attack the lagoon. Will probably need to wrap this in to the cost of a plant upgrade.

Subject: Lagoon 1 estimated costs

Ryan, you asked for River City’s estimate. They’ve given me an informal cost breakdown (below). I worked with him on breaking it down a way the made sense to me, given I’ll need to go out for bid.

Cost per dry ton was $360.

Given…

4200 bone dry tons in the lagoon, 20,000 wet tons (which is 7’ of biosolids at an average of 5% solid)

with a profit margin of about 15%,

assuming 12 hour work days with their specific equipment,

$46,000 for mobilization

$46,000 for demobilization

$654,344 for processing

$594,820 hauling and landfilling

$157,500 for polymer

$151,457 10% contingency

So we are looking at a theoretical estimate of $1,514,573.12 to remove all the material. Interestingly, if I assume no significant biosolids have been removed in 12 years, that means an alternate universe Molalla who HAD been pumping biosolids would have spent about $126,214 annually, which is about the number I would expect a normal town our size to have to conservatively spend on biosolids handling. Don’t you think?

Thanks,

Andy Peters
