Drains are an important part of the
“plumbing” of a dam. Drains consist of both solid and slotted PVC
pipe placed in beds of sand located throughout the dam.
Drains are designed to capture excess
water, both groundwater and seepage from precipitation, and
transport it safely out of the dam, preventing structural damage to
the structure.
HorseThief Reservoir will incorporate both chimney and blanket
drains, and will use more than 80,000 cubic yards of sand.
