Innovation and research for water infrastructure for the 21st century

Synopsis: North America water infrastructure managers reduce catastrophic failures of tremendous social consequences by rational water infrastructure management plan with optimised preventive maintenance strategies. The condition states of water infrastructure determine different rehabilitation options. These survival probability based options then facilitate prioritising infrastructure inspection and rehabilitation/replacement.

Containment wall construction at DNAPL-contaminated site

Synopsis: A water-bearing granular soil layer within the subsurface of a former manufactured gas plant site was impacted with tarry dense non-aqueous phase liquid (DNAPL). A containment wall was constructed to prevent the migration of DNAPL to offsite properties. Four different self-hardening slurry materials were evaluated for their compatibility with the DNAPL. The study simulated the emplacement of slurry material and determined the effect of DNAPL interaction with the slurry material. Because of good chemical compatibility and ease to use with the vibrated beam construction method, IMPERMIX slurry mix was used for the construction of the containment wall. The entire project was completed under the budget and two months ahead of schedule.
