Sludge Reduction at a State Park – Testimonial

It was a pleasure to work your staff on today to assess the volume of sludge in the State Park wastewater treatment lagoon. I appreciate the desire of you and your staff to maintain the wastewater lagoon system to best protect the groundwater of Platte County as well as the ground and surface waters in and around the Glendo State Park.

After performing the sludge analysis and comparing last year’s data, it is obvious that substantial sludge reduction occurred as a result of the use of microbial products.

The overall savings ranges from $13,200 to $15,900.

Last year in Pond 1 you had a sludge volume of 29.0% and the percent solids of the sludge likely ranged in the 12 to 14 percent which would have cost the State Park System $16,500 to $19,900.

Today, the sludge volume was at 13.4% with the percent solids likely being 9% to 11% and would cost $5700 to $7000 to dredge.

This is a savings of $10,800 to $12,900.

On Pond 2 we had similar results reducing the sludge blanket from 10.9% to 6.9% and a percent solids reduction of 12 to 14 percent down to 9 to 11 percent. The cost to dredge last year on Pond 2 was approximately $5100 to $6000.

Today we determined that the cost to dredge this pond was $2400 to $3000 resulting in a savings of $2700 to $3000.

The overall savings ranges from $13,200 to $15,900.
