The Overseas Development Administration, part of the British Foreign Office, and now known as the Department for International Development (DfID), had operated the so-called Emergency Engineering Unit in Bosnia since 1992. It already had two staff in Mostar when the EUAM was established: Denver Brown was working on water supply and Tom Connolly on power. They had done heroic work under fire to restore some vital services, although it was partial and unreliable. Denver left in December 1994 and Tom transferred to the EUAM and stayed for a further two years. They were a great help in getting us off to a flying start. Denver Brown had in part resolved the emergency in early 1994 by installing a generator and pump to take untreated water from the river to supply the east side distribution network, although the pressure was too low to reach higher ground or top floors.

Two other agencies were undertaking important projects when the EUAM was set up. Technisches Hilfswerk (THW) was attempting the repair of Studenac Well Field but had encountered serious practical problems, and project completion was long delayed. It was also repairing Mazoljiće Reservoir and subsequently also rebuilt a water main crossing of the river (near Lučki Bridge). The International Committee of the Red Cross (ICRC) was also supplying materials to allow repair of secondary distribution networks in the Cernica and Donja Mahala neighbourhoods as well as the Djikovina pumping station.
