The funds for the construction, removal, relocation or replacement of any facility designed to provide water, water treatment or sewer services may be allocated and appropriated for such priority expenditures by the city or county receiving them for expenditure by the agency itself or by the local governmental agency which performs the service wholly or partially within the boundaries of the city or the county making the allocation for such purposes.
