System Design

A system will be designed to correct specific problems at a site. Different problems require different solutions; for example, some sites cannot be treated passively and require a specific type of active treatement. Design of a treatment system is affected by a variety of factors including (water) chemistry, flow, and topography (i.e., the available space and the contours of this space).

Our system designs are dependent upon the data collected in the watershed assessment. The data is analyzed and a 'best' system is designed to be constructed. The intent of the system is to to improve the water quality entering the stream. Treatment systems will aid in raising the pH and precipitating out metals, (i.e. iron, aluminum, and manganese) so that fish and aquatic organisms can once again thrive in the degraded stream.


Restoration plans include a conceptual design. A conceptual design is a treatment system design which is likely to succeed for the specified site. While the water chemistry is known, the topography is estimated. Conceptual designs are likely to approximate final designs closely, but a detailed survey of the area and/or soil investigation may indicate that the conceptual design requires refinement or replacement.


After a survey and a wetland delineation are completed, we have a clearer picture of the topography and composition of the land. This new information may not impact the conceptual design at all, or it may require substantial modification in the layout and sizing of design components. After the conceptual design is properly adjusted, our engineer then creates construction ready blues. At this point we consider that we have a "final" design.
