  • Expropriation of Water Lease in Dar es Salaam, Tanzania
    Biwater claimed US$20 million from the Government of Tanzania for expropriating a lease granted over the water system in the capital city, Dar es Salaam. Castalia presented expert evidence for the Government to an ICSID arbitral tribunal establishing that the lease-holding company had no remaining value. The tribunal accepted our arguments in its award stating (at paragraph 795) that “the correct approach to valuation here is that set out in the Castalia Report.” The tribunal made the resounding conclusion that City Water had no economic value and no award of damages was made. Castalia’s evidence was also accepted in a related proceeding heard by the United Nations Commission of International Trade Law, City Water Services v Dar es Salaam Water and Sewerage Authority (UNCITRAL UN6761)
