Drainage Rates
All land and properties within a Drainage District are deemed to derive benefit from the activities of an IDB and therefore subject to contributions to the expenses of the IDB paid annually to the Board. For the purposes of rating, properties are divided into:
- Agricultural Land and Buildings (fields, farmhouses, barns, glasshouses, stables, silos etc.)
- Other Land (such as domestic houses, factories, shops etc).
Occupiers of all “Other Land” pay Council Tax, Business Rates or Local Services Support Rates to the District or Unitary Authority who then are charged a Special Levy by the Board in proportion to the annual value of this “Other Land”. The Board, therefore, only demands Drainage Rates direct on Agricultural Land and Buildings.
