Comparison of Trenchless and Excavation Technologies in the Restoration of a Sewage Network and Their Carbon Footprints

open access: yesResources
The restoration of aging sewer networks is a fundamental remediation approach with the aim of renewing or improving existing systems. Remediation methods include repair, renovation, and replacement (renewal). The restoration of a sewer network itself can

Delayed pipe replacement halves environmental impacts but quadruples water loss

open access: yesAWWA Water Science, Volume 6, Issue 2, March/April 2024.
Abstract Scheduling pipe replacement is critical for water distribution systems (WDSs) when managing finances and water loss. WDS replacements are often delayed due to high immediate costs without considering long‐term environmental consequences. This study is the first to examine a real‐world WDS using a novel workflow transferrable to other WDSs that

Laboratory Evaluation of Vibration Isolation of Dynamic Loads Caused by Machine Foundations by Surface Trenches

open access: yesShock and Vibration, Volume 2024, Issue 1, 2024.
Measures should be taken to prevent the effects of vibration caused by dynamic loads of machines. Research has shown that trenches can effectively reduce vibrations caused by machine foundations. It has been determined that the open trench provides the best performance against vibration, but it is not practical due to operational limitations ...
