Each utility generates revenues via user pay that reflect the costs of managing the infrastmcture in the region. Drinking water supply, sewerage and management of solid waste represent the majority of both operating and capital budgets, and are financed through utility fees. Property taxes account for a small portion of the regional budget, and support the Regional Parks system, as well as other services including Air Quality Management and Regional Planning activities. The Metro Vancouver Housing Corporation is financed almost entirely through rents paid by tenants. The budget represents a CAD 427 annual cost to the average regional household. While the fiscal mandate of LGUs was broadened by the Local Government Code 1991 to include revenue assignments, devolvement of expenditure responsibilities, intergovernmental transfers, and subnational debt/credit financing (Department of Finance, 2015), fiscal decentralisation has been limited in practice and authority and resources remain highly centralised: the proportion of total tax revenue collected by LGUs in the Philippines remains low at around 5.2% in 2013, and has not evolved since 2000.
