Models validations show a capacity to avoid up to 40% of the breaks over the next 3-5 years.
Each avoided break reduces the direct cost of repair, physical damage, wasted water, and service interruption to which one must also add the -more difficult to quantify- indirect cost including the effect of negative publicity. For example, when a primary school is flooded or its water service is interrupted in the middle of the day, families have to leave their office and pick up their children. This will for sure make the headlines.
Accomplished for system with length 846 mi; AC, CI, DI pipes; average age 41 yrs old; average yearly break rate 5 breaks/100 mi/yr.
$1.2B (65%) reduction of R&R spending over the next 35 years when using utility-specific, risk-based EULs computed by infraPLAN compared to generic EULs assumed by the industry.
Accomplished for system with length 1,200 mi; CI and DI pipes; average age 59 yrs old; average yearly break rate 7 breaks/100 mi/yr.
Report stamped by infraPLAN helped utility secure the necessary rate increase to fund the program of rehabilitation we had recommended.
Accomplished for system length 297 mi; AC, CI, DI, ST, PL pipes; average age 57 years old; 19 breaks/100 mi/yr.
6% of length replaced over 2014-2019; 2019 break rate projected in 2014 achieved with 40% of the recommended R&R because utility strategically picked PL and ST pipes identified by infraPLAN with average yearly break rate 1.8 to 7.4 times larger than the break rate of the pipes that are still active.
Accomplished for system length 506 mi; AC, DI, ST, PL piped; average age 33 yrs old; average yearly break rate 41 breaks/100 mi/yr.
Scenario 1: break rate decreases from 9 to 7 breaks/100 mi/yr. between 2018 and 2038 with an average of 42 mi of R&R per year.
Scenario 2: optimal selection allows for slight increase of break rate to 10 breaks/100 mi/yr. with, this time, an average of 18 mi of R&R of strategically selected pipes.
Accomplished for system Length 2,886 mi; AC, CI, DI pipes; average age 60 yrs old; break rate as of 2018 9 breaks/100 mi/yr.
