When designing, commissioning and maintaining piping systems for adoption in Section 104 agreements, developers and their selected designers have a plethora of product and material options and a number of considerations to consider. Home / Features / Getting to Grips With… Section 104 Agreements If you are proposing a pumping station for adoption as part of your project, you must refer to our design requirements for our “local pumping station practice”, which you will find in our latest pumping station supplement (PDF 7.259 KB opens in a new window). The pumping station is covered under the same S104 agreement as the gravity sewers. A smooth design and submission process often means that sewers are easier to accept and that attachment to the developer can be reduced – often leading to a faster and more cost-effective construction program. For water management strategies to be successfully approved and for an agreement to be reached under Section 104, it is important to assess the needs of each site in order to provide the optimal solution. The newly elected Conservative government has committed to creating 275,000 affordable housing units by 2020. In this context, the volume of applications for section 104 agreements is expected to increase exponentially. To avoid delays and additional costs for their projects, developers need to consider drainage planning and make important decisions – including material selection – as soon as possible. The path to an agreement under Section 104 begins with an initial flood risk assessment and takes into account drainage requirements for the entire area to ensure that local surface water sanitation and drainage systems are taken into account and not overburdened. A Section 104 agreement (under the Water Industry Act 1991) is an agreement between a developer and a sewerage company for the adoption of sewer systems for development.
There are strict rules for getting an agreement that can be a minefield for developers. The process is often on the critical path of a project and decisions related to it can have a huge impact on costs. In Wales, mandatory building standards require that an agreement be in place under Section 104 before development can progress. Since this legislation is likely to be implemented in England, it is essential that all stakeholders in housing projects understand the process. If you have your technical agreement from us for your sewer system design, you must be in a section 104 agreement so that we can formally handle the sewers. We are aware that construction may need to begin before the S104 agreement is signed by all parties. In order not to delay the start of your work, you can complete a quick request after receiving the technical receipt and paying the S104 fee. During the work, we carry out inspections to verify compliance with the S104 agreement. If inappropriate work, materials or anomalies are detected, we will inform the field contact of the defects.
You can enter into an agreement in accordance with Section 104, either by asking us to establish one and provide all necessary documents, or by telling us that you intend to prepare your own legal agreement. Please note the Model Sewer Adoption Agreement. What are the considerations in choosing the drainage system? Some of the codes invite us to consult with our customers, where we intend to use a local practice rather than industry standard practice. Our guide to offering private sewers available for acceptance provides all the information needed to provide existing sewers for acceptance.
