Maintenance and repairs of small hydropower stations require a maximum of flexibility and very often the courage to find and realize unconventional solutions. Whereas large scale hydropower companies usually do not compromise in terms of scope or execution of individual works and costs frequently are not the major issue, companies active in the small hydro sector fairly often face the whole spectrum of problems that can occur whilest costs are a major issue. So for example in one case it needs to be decided upon whether to replace or to weld a broken cast iron turbine cover, then to decide whether to replace or rebuild a badly damaged francis runner, whether to manufacture new wicket gates from epoxi moulding material, or as usual from cast iron. In an other case there are problems with the hydraulic governor and in the other difficulties with the electrical equipment.
