CAO RECOMMENDATION:
Approve project specifications for " Reservoir Number 1 Liner/Floating Cover, Specification No
500.9751.510.553 ", authorize staff to advertise for bids and authorize the CAO to award the
contract if the lowest responsible bid is within budget
DISCUSSION:
The existing floating cover is approximately twenty years old. The cover material has outlived its
useful service life and has degraded to an extent that minor spot repairs are no longer capable of
maintaining the integrity of the cover. Additionally,the ability of the cover to shed storm water is
has been impaired by sags and folds in the cover due to its advanced age.
The reservoir consists of a reinforced fabric material stretched over the top of a concrete lined
containment area.Constructed in the 1920's,the joints between concrete slabs do not hold water as
the reservoir level rises to greater than half its rated capacity.
To increase the useable capacity and to protect the water quality of this reservoir, money was
budgeted to install a dense plastic liner and replace the cover.
