New Sewer Connections & Diversion
what we do
Exjet provides professional sewer connection and diversion services for developers, contractors, and property owners across Devon, Cornwall, Dorset and Somerset. From the initial consultation to the final inspection, we manage the entire process, ensuring compliance with all legal requirements and delivering work to recognised industry standards.
Complete Sewer Connection Services
Connecting a property or development to the main sewer requires careful planning, approval from the relevant authorities, and safe execution on-site. We offer a free initial consultation to discuss requirements and guide you through the process. Our in-house expertise and industry accreditations allow us to act as a single point of contact, managing applications, permits, technical drawings and on-site works.
Managing the Legal & Approval Process
Section 106 Applications
A Section 106 agreement is required to connect a private drainage system to a public sewer. We prepare and submit the application on your behalf, ensuring all drawings and specifications meet the standards of the local water authority.
Section 50/171 Notices & Permits
Where connections or diversions affect a public highway, a Section 50 or 171 licence is needed. We liaise with councils and highways teams to secure these permits and coordinate traffic management, avoiding unnecessary delays.
Sewer Design & Drawings
Our engineers and CAD technicians produce detailed drawings and mapping to support each application. These documents are submitted to the relevant authority as part of the approval process, providing clear evidence that the design meets technical and safety standards.
Sewer Diversions & Build-Over Agreements
Sewer diversions are often required where developments, extensions or infrastructure works impact existing sewers. We handle the full diversion process, from initial planning to final reinstatement. For properties where building work is planned over or near an existing sewer, we also support build-over agreements, negotiating with water authorities to ensure compliance and protect clients from future liability.
Technical Delivery & Standards
Safe & Efficient Works
Once approvals are in place, our teams carry out the work using modern equipment and proven methods. We work with our partner Greenlight Highways to provide traffic management where required, and reinstatement is completed to highway standards. Throughout the project, we minimise disruption to surrounding areas and keep work on schedule.
Approved & Accredited Teams
Exjet are approved by both highways and water authorities, giving clients confidence that all works are delivered responsibly and to the correct standards. Our water authority approval enables us to act as a specialist contractor for sewer connections, diversions, and Section 106 applications, liaising directly with water companies on behalf of our clients throughout the approval and construction process. Our accreditations include Constructionline Gold, SafeContractor, UKAS, Trading Standards, SMAS, CSCS and FSB.
