2014 marked the beginning of a new type of project management for REAS - Lagoon Closure. The lagoon, constructed many years ago, was used as an off site waste water treatment area. The lagoon consists of three cells which the waste water would flow through to consecutively reduce the amount of waste materials due to natural settling and filtration, resulting in an excess of sludge waste material in the first two cells and eventually a build up in the third cell as well.
In 2012, the property owners hired us to clean up the lagoon to significantly reduce the amount of sludge in the lagoon. The traditional method of doing this was to dredge the material mechanically and haul it away to be treated and dispersed at another site where it can be naturally broken down and absorbed into soil. We came at the problem with a different approach. We are using natural probiotic bugs to eat the sludge and naturally "scrub" the lagoon cells.
In the summer of 2014 we made the initial applications of the probiotics, with astonishing results. When we measured the depth of the sludge after 44 days of application, we found that there was a 30 to 40% decrease in the amount of sludge in the two cells that received the initial treatment.
With another 2 years of applications to be done scheduled for this year and next for all three cells of the lagoon, we expect to see phenominal results.
