What you don’t know can hurt you

2015 SANITARY SEWER FAILURE § § § Installed in 1983 66 -inch RCP Sanitary Sewer Repair Cost $138, 000

SANITARY SEWER CONDITION ASSESSMENT § § Multi-Sensor Inspection Platforms HD CCTV Camera Laser Ring Profiler Sonar 2 D Laser Profiler Sonar HD CCTV Camera

SANITARY SEWER CONDITION ASSESSMENT § § § 47 miles inspected 24 -inch to 72 -inch 2 projects fast tracked to design

2015 WATER MAIN FAILURE § § § Installed in 1982 42 -inch C 301 Water Main Repair Cost $718, 000

WATER MAIN CONDITION ASSESSMENT

WATER MAIN CONDITION ASSESSMENT § § Water Research Foundation/EPA Study on PCCP (2012) q 96% of pipes are in good condition (no wire breaks) q Distressed pipe can still have a low risk of rupture for decades Arlington’s results consistent with study findings q 4 projects - 6. 9 miles inspected q 24 -inch to 60 -inch C 301 & C 303 q 1. 7% segments with wire breaks

WATER MAIN REPLACEMENT § 588 miles of “Asbestos Cement” pipe (42%) § 90% of main breaks occur on “AC” pipe § Overtime Costs are approximately $400 k/year § Current replacement rate is 8 miles/year § How to accelerate replacement without cost impact

WATER MAIN PIPE BURSTING § § Reduced construction time and customer disruption Independent of roadway replacement schedule Utilizes existing alignment – right-of-way preserved Reduced costs

WATER MAIN PIPE BURSTING Day 1 Installation HDPE Main Day 2 Restoration and cleanup

WATER MAIN PIPE BURSTING § § 3 rd party contractor q 20, 000 linear feet/year q Dual bid – open cut ($160/ft) vs. pipe bursting($128/ft) q $680 k cost savings/year In-house pipe replacement q Year 1 – 20, 000 linear feet q In-house cost ($56/ft) q $2. 1 M or $1. 4 M cost savings/year
