Minimum Flow Units - Case Study

Environmental regulations are becoming more stringent and the minimum by-pass flow requirements are generally increasing in North-America. Many of our small hydro technologies are perfectly suited for this type of application whether it is to replace an existing pressure reducing valve or implement a new turbine upstream of the by-passed reach of an existing hydro plant. Shown below is an example of a project where a turbine was integrated upstream of a by-passed reach to produce energy while securing a minimum flow for environmental considerations.
