Another approach to water pollution prevention and control is by factoring in the water utilization permit process concern for the polluting impact of (a) "return flows" - i.e. the waste water or effluent which results from a permitted water utilization - on the water body into which the effluent is discharged, and (b) well drilling, on the quality of groundwater formations. This approach is evidenced in subsidiary legislation by a variety of techniques. These include specific requirements as to the documentary evidence to be submitted by applicants for a water utilization permit (I); standard obligations applicable to all water utilization permit holders in respect of the level and type of treatment required of the effluent resulting from a permitted use (II); procedural and substantive prescriptions which reflect specific concern for water pollution in the process of reviewing and deciding on permit applications for the use of water (III and IV), requirements to the effect that, in the formatting of water abstraction and use permits, terms and conditions be entered with specific regard to water pollution prevention and control (V and VI); and the grant of authority to curtail a water abstraction and use permit in the specific case of disregard by the permit holder of the permit's anti-pollution clauses (VII).
