Pipes

Factors Considered When Designing Pipes

Slide 21

Pipes Pipes should be located where they will not cause problems such as erosion of the lagoon sidewall.

Slide 25

Slide 26

Pipes Frequent inspections of the piping system cannot be overemphasized.

Lagoon Maintenance

Slide 29

Lagoon Maintenance The vegetative cover on the dam should be well maintained. Fertilize each year if needed as recommended by a soil test to maintain a vigorous stand of grass.

Lagoon Maintenance Brush and trees on the embankment must be controlled. This may be done by mowing, chopping, or a combination of these practices.

Weekly Lagoon Maintenance Inspections
