General requirements


Utilization of SW with different levels of treatment and dilution is permissible both for irrigation of standing crops, ferti-irrigation, and once a year land application before sowing of a crop.pre-sown irrigation.

The distillery shall hire a full-time agricultural scientist and form an irrigation cell for the management of its agricultural operations. It shall have laboratory facilities for analysis of various water and soil quality parameters listed in this protocol.

The distillery shall enter into a Memorandum of Understanding (MoU) with a near by university or institute to advise on the rate of application of the SW rotation of crops and monitor the quality of groundwater and soil in accordance with the requirements of this protocol. The university/institute may expand the scope of its participation if it is in the interest of monitoring and improvement of the environment.

The distillery shall construct impervious lined storage tanks for storage of treated effluent before its application on land. Dry soling on clay or black cotton soils shall not be allowed. Direct transport of the treated SW from a treatment unit to the field shall not be permitted.

The total capacity of the storage lagoons shall not be more than 22.500m irrespective the production capacity of the distillery. The distilleries may decide on the volume fractions of the lagoons for the storage of biomethanated SW and secondary treated effluent on the basis of their utilization plans for pre-sown and ferti-irrigation.

The command area for SW utilization shall be with in a distance of 20 km from the distillery in order to facilitate easy monitoring and effective control. The distillery shall construct a distribution network of impervious conduits to cover the area irrigated under the utilization scheme.

In specific case where the requirement 1.6 above cannot be met and the treated SW has to be transported through tanker lorries, details of such proposed application giving area and location of fields and number of tankers of specified capacities proposed to be used, should be submitted to the State Pollution Control Board (SPCB) for their prior approval. The distillery shall keep a record of such application using a Transit card giving the following details:

  • Tanker/lorry number
  • Date and time of loading and unloading
  • Destination/field address
  • Name of receiving person
  • Distance traveled
