RFP NO: 2016WD-01 - CHASE GULCH DAM & RESERVOIR TOE DRAIN REPAIR

The City of Central is inviting proposals from qualified contractors to repair the Chase Gulch Reservoir Dam Toe Drain. The original Chase Gulch Dam & Reservoir 6-inch ADS toe drain has had a reduction in drain flows and the water table height within the concrete faced rockfill dam has increased in height the past 10 years. The reduce flow and higher water table indicate that the existing toe drain pipe is clogged or crushed. Water is seeping from the dirty rockfill buttress due to the high water table inside the dam embankment. The seeping water is becoming a nuisance for traffic in the valley bottom because of muddy conditions. A new toe drain will help lower the ground water table
within the dam embankment. The project is under the State Engineers Office of Dam Safety Jurisdiction.
