DESIGN
Design Methodology. This is a review of preferred
engineering practice in determining flow rates, capacity
requirements, and system sizing. Included are
watershed area definition, drainage pattern layout,
factors for rainfall frequency/duration/intensity, runoff
coefficients, and calculation of peak flow rates and
system storage requirements. Guidelines for sizing pipe,
manifolds, and fittings are presented, and are supported
on the CD-ROM by AutoCad Release 13 drawing blocks
which can be inserted into specific site design plans. The
section concludes with a summary of installation
requirements, including minimum cover, backfill, filter
fabrics, and siltation cleanouts.
