The board of any public service district which purchases water, sewer or stormwater service from a municipal water, sewer or stormwater system or another public service district may, as an alternative to hiring its own general manager, elect to permit the general manager of the municipal water, sewer or stormwater system or public service district from which such water, sewer or stormwater service is purchased provide professional management to the district, if the appropriate municipality or public service board agrees to provide such assistance. The general manager shall receive reasonable compensation for such service.
