EGCA Magazine ---- In any business, there is no greater endorsement than a satisfied customer. For EGCA Affiliate member Bio Clean Environmental Services, Inc., that most recently satisfied customer was Nick Renn, P.E., of the City of Laguna Niguel. Earlier this year, but after the traditional rainy season had ended, Bio Clean completed installation of one of its patented nutrient
separation baffle boxes. The installed unit, news of which was reported in the June issue of EGCA Magazine, is located approximately 500 ft. upstream from a detention pond.

" All that vegetation was a wetland," according to Bio Clean's Greg Kent. "Over the years, the pond had become loaded with sediments, making it extremely difficult to clean." At the time of the installation, the City of Laguna Niguel's Nick Renn noted, "It will take a few months to see how effective it is, but we are expecting it to do well."

Renn's expectations were met, unexpectedly a bit early, when, as Renn noted in early September, "We inspected the baffle box, and it had three feet of silt in it. Now that's kind of unusual for this time of year. Certainly, we had no rainfall to speak of. But, as it turns out, there is a housing development under construction upstream where some new graded building pads were being installed.

" Prior to laying out the concrete foundation, the builder saturated the dirt due to the area's expansive soil conditions," Renn
explained. "The temporary dams the builder had constructed to hold the water broke, and all the dirt came downstream. Fortunately, the baffle box collected it."

" So I would say that the baffle box installation is working very well for us," Renn said.
