Bottling Plant

Issue:  A bottling company in Minnesota discharges some 6,000 gallons per day of wash   down water with a COD of 40,000 – 70,000 mg/L. The material is too strong for the local wastewater treatment plant to process, so it must be trucked off site. Action:  Design/build an aerobic onsite treatment system using micro bubble aeration…

Geocell Shoreline Stabilization

Issue: Loose shifting sand makes access to this beach difficult, and winter dock removal destabilizes the lake bank. Action: Installing geocell pervious stabilization halts erosion, allows for infiltration to clean runoff before it reaches the lake, and creates secure footing for beach access.

Shoreline Stabilization – Soft Armor

  Issue: A dangerous old timber stair needs to be removed from a steeply sloping shoreline. Removal may destabilize the hillside.   Action: Treated ties are removed, and straw logs, erosion fabric, seed and plants are installed. Deep-rooted native shrubs, ferns, sedges, grasses and flowers will restabilize the slope, slow and filter runoff, and capture…

Municipal Raingarden

  Issue: A swale carries runoff from an entire city block to a storm sewer pipe that eventually empties directly into a wild and scenic river. Action: Two raingarden basins and a vegetated swale minimize and infiltrate the majority of the runoff and add tremendous diversity and beauty to the site.

Residential Raingarden

  Issue: Roof, gutters, yard and driveway shed a substantial amount of unfiltered runoff down a steep slope onto the neighboring property and into the lake.   Action: Three raingardens were created below downspouts and downslope of the driveway surface to capture, filter and infiltrate runoff. Deep-rooted, moisture-loving sedges, grasses and flowers will add beauty…

Issue: A lakeside bar and grill is served by an onsite sewage treatment system. The drain field mound is ponded and will soon create a surface discharge if not repaired. Space is restricted and the owner wants to avoid a replacement drain field mound. Design flow is 1,177 GPD, tanks include three 1,500-gallon septic tanks.…
