A continuous-control DRL agent trained on an EPANET digital twin sets pressures at three pumping stations, keeping all 35 DMAs in service with an estimated 14% energy saving.
WANDA surge study of an irrigation pumping main on Hudariyat Island: a 1.5 m³ bladder surge vessel is sized by parameter study, with a safe demand closing time.
WANDA surge analysis of a 2.8 km DN500 sewage rising main upgraded to three duty pumps, confirming the existing surge protection meets a −0.1 barg criterion.
WANDA surge study of two upgraded TSE pumping stations, showing that existing surge vessels plus one new air valve protect the system, with safe restart and valve closing times.
WANDA transient study of twin DN900 inlet mains, two ring mains and 18 PRVs. It confirmed the protection philosophy, removed a harmful interlock and set the valve stroke times.
Bentley HAMMER surge study of a pumping station and two transmission mains. Two 83.9 m³ air vessels lift the minimum pressure from −0.94 to −0.31 barg with no column separation.
CFD of a 90 m diameter potable water tank: tracer residence time and dead zones, roof-driven thermal stratification and chlorine decay, with an inlet change tested to keep a chlorine residual throughout.
Fluent CFD of a common pump suction manifold confirming an even flow split between six duty pumps (within 1%), with mesh-independent results and no geometry change required.
ANSYS Fluent CFD of a 505 MLD screening building covering flow distribution, recirculation and particle tracking to locate sediment-prone zones, with design improvements recommended.
EPANET study of a sewage lifting station and 710 m HDPE rising main, confirming the pump selection and self-cleansing velocities across water level and roughness cases.
