Completion of the method statement for a direct connection to the public sewer. Your are required to submit a sewer connection application form under Section 106 of the Water Industry Act 1991 together with your Section 104 adoption application form. This should identify the total number of direct connections to be made to the public sewer and your contractor is required to complete a method statement for each of these. A method statement form and guidance for contractors is available to download on Anglian Water s website. Payment of the Technical Vetting and Administration Fee (TVA) with your application to connect to the public sewer. As stipulated above you are required to make an application to connect to the public sewer and to pay the TVA. The value of the payment required is dependent upon whether the proposed connection is direct or indirect. If you are proposing to connect to the existing public sewer, you are required to pay the direct TVA; however, if you are proposing to connect to an existing private sewer you are required to pay the indirect TVA. If the sewer you propose to connect to is under your ownership or the ownership of another developer and is or will be subject to a Section 104 Adoption Agreement, the connection is considered to be indirect and the indirect TVA is payable.
