Abstract

The world's largest single PCCP project is owned and operated by North Africa's Great Man Made River Authority (GMRA). GMRA supplies water from the world's largest well fields to some of its biggest reservoirs. The water is conveyed from aquifers in the middle of the desert to the coast in 4m (157Prime;) diameter prestressed concrete cylinder pressure pipes (PCCP). The main conveyance network, measuring 3,500 km (2,200 miles), utilizes almost half a million pipes and transports 6.5 million m3 (5,270 acre-feet) of water per day. GMRA has been using the Pressure Pipe Inspection Company's (PPIC) Remote Field Eddy Current / Transformer Coupling (RFEC/TC) technology to provide pipeline condition assessment information since April of 2000. To date, GMRA has inspected over 1,500 km (932 miles) of PCCP using the RFEC/TC system to detect and quantify prestressing wire breaks in its PCCP. The results provided by the RFEC/TC technique have enabled GMRA to selectively repair or replace individual pipes - making the cost-effective management of this enormously complex pipeline system possible. During this same period, systematic analysis of the data gathered during inspections has led to advances in PPIC's understanding of the RFEC/TC technique and its application it to the evaluation of water distribution systems.
