Work Description & Methodology
The project involved heavy machine mobilization for bulk earthworks. SNG’s methodology focused on increasing retention volume while reinforcing the pond walls to prevent seepage. Stage 2 involved the fine-tuning of hydraulic structures to improve flow control. Environmental protection was a priority, with silt fences and runoff management strategies maintained throughout the construction lifecycle.
