Section 3.4 Lists supporting documentation required. Section 4 Select the treatment systems suitable for this site and the discharge route. Section 5 Indicate the system type that it is proposed to install. Section 6 Provide details, as required, on the proposed treatment system. Notes: All calculations in this form are automatic. Where possible information is presented in the form of drop down selection lists to eliminate potential errors. Variable elements are recorded by tick boxes. In all cases only one tick box should be activated. All time record fields must be entered in twenty four hour format as follows: HH:MM All date formats are DD-MM-YYYY. All other data fields are in text entry format. This form can be printed out fully populated for submission with related documents and for your files. It can also be submitted by email. Step 1: Goto Menu Item File, Save As and save the file under a reference relating to the client or the planning application reference if available.
