Raw Water Transmission Lines from Helwan to New Capital

Project Description

The project aims to transfer raw water (1.5 million m³/day) from the new water intake at the River Nile bank in South Helwan to the Water Treatment Plant in the New Capital. It comprises the following components:

Intake: to carry raw water via three pipelines (each 50 km long) from an intake booster pump station that includes pump house, electrical substation, transformer, generator, and service buildings.
Three Transmission Pipelines: each with a diameter of 2,200 mm and length of 50 km.
Booster-Pump Station (4 pumps): The station has a capacity of 800,000 m³/day in Phase 1 and total capacity of 1.5 million m³/day at the end of Phase 2 and comprises underground water tanks (240,000 m³), pump house, electrical substation, transformer, and a generator; in addition to service buildings (mosque, administration building, store, and workshop).
A Water Treatment Plant (1.5 million m³/day): Raw water is treated on four stages, each with a capacity of 400,000 m³/day. ECG scope of works includes construction supervision services in addition to civil works for the fences and service & administrative buildings.

ECG scope in terms of piping works covers hydraulic calculations, hydraulic profile, study of hydraulic balance of the pipeline, strategic ground tanks, and transmission pipelines & crossing with canals, drains & roads. Additionally, water hammer analysis is administered to protect the pipeline from hammer impact.

ECG scope in terms of booster-pump station works covers hydraulic calculations, plant layout, piping & instrumentation diagram (P&ID), and plant mechanical general arrangements.
