Expansion of the Shoket sewage works

The challenge

Working at an active sewage works without impairing its functioning requires precision planning.

Our part in the project management

Planning and supporting the construction of a sewage works with activated sludge technology for providing a 30,000 m3 per day flow rate and a follow-on project. The process includes pretreatment of waste water with filtration at two degrees and removal of sand, followed by treatment by activated sludge using 3 reactors with 2 final precipitation basins. The secondary treated water is run to a tertiary treatment array, which includes sand filtering and disinfecting by chlorination, followed by running by gravity to a nearby treated water reservoir and from it for recovery for agricultural use. The sludge is treated at the works by thickening on a gravity belt, long-term aerobic stabilization and final filtering using belt filters.
DHV has also planned peripheral auxiliary systems including a complex double pumping station that has multiple levels for the two main sewage lines and air treatment and odor neutralization systems.
