Water Resource Plan, Qatar

Castalia developed a strategy for optimal management of water resources as part of Qatar's National Development Strategy 2018-2022. Qatar’s over-abstraction of groundwater and high rates of desalinated water use were not environmentally or fiscally optimal.

Water Resource Regulatory Framework, Philippines

Castalia defined water allocation principles for the National Water Resources Board in the Philippines that were socially acceptable and economically efficient for both urban and agricultural users.

Water Sector Regulation Notes

Castalia wrote six explanatory notes on key topics in water supply and sanitation sector regulation to clarify the meaning of key terms, and to provide a foundation for effective regulation. Although policy makers agree that regulation is key to reforming water utilities worldwide, they disagree on the best approach to regulation in various situations. Many lack a clear, consistent, way of thinking about regulatory design.

Castalia helped the Government of the Sultanate of Oman merge various water providers into three regional utilities, develop business plans, calculate cost recovery tariffs, recommend subsidies, and develop a new regime for economic regulation. We assessed the likely impact of the reform. Oman’s government was spending $447 million each year to provide water services and wanted to reduce public spending on water while expanding service.

Water Supply Private Investment Structure, Indonesia

Castalia appraised the Umbulan Springs Bulk Water Supply Project and found that it was economically and financially viable with Viability Gap Funding. We recommended that the IIGF provide a guarantee if the Provincial Government implemented our recommendations that would mitigate the residual Project risks that we identified. The Umbulan Springs Bulk Water Supply Project would increase water access for residents of the East Java Province, but it needed payment guarantee to attract a PPP company. The Indonesian Infrastructure Guarantee Fund (IIGF) would only provide a guarantee if it were satisfied the Project risks were well managed.
