Drainage Agreement
Professional drainage agreement services in the UK. CGS Civils manages drainage adoption agreements and sewer approvals for developments.
Drainage Agreement
A drainage agreement is a key requirement for developments that involve new, altered, or diverted sewer infrastructure. The approval process can be complex, often requiring detailed technical submissions and ongoing liaison with the relevant water authority. At CGS Civils, we provide expert support to manage drainage agreements efficiently and in full compliance with statutory requirements.
Our team supports clients throughout the entire process, ensuring drainage infrastructure is correctly designed, submitted, and approved in line with water company standards.
Professional Drainage Agreement Services in the UK
CGS Civils delivers professional drainage agreement services for residential, commercial, and mixed-use developments across the UK. We work closely with developers, consultants, and water authorities to ensure all drainage proposals meet adoption, connection, and diversion requirements.
Our experience allows us to manage technical submissions proactively, helping to reduce delays, avoid unnecessary revisions, and maintain project momentum during the approval process.
What Is a Drainage Agreement?
A drainage agreement is a formal arrangement with the relevant water authority that governs the design, construction, and future adoption of new or modified drainage infrastructure. These agreements ensure that sewer systems are constructed to an adoptable standard and can be safely maintained in the long term.
CGS Civils supports a full range of drainage agreements, including drainage adoption agreements and drainage easement agreements, ensuring developments comply with all statutory and legal obligations.
Drainage Adoption and Easement Agreements
In addition to technical approvals, CGS Civils supports drainage adoption agreements and drainage easement agreements where infrastructure crosses third-party land or requires long-term access for inspection and maintenance.
We ensure all agreements are underpinned by clear, compliant engineering designs that satisfy both statutory and legal requirements.
Coordination with Drainage Design and Construction
Drainage agreements form a critical part of the wider drainage design and construction process. CGS Civils ensures all drainage agreement submissions are fully coordinated with drainage strategies, drainage plans, and overall site layouts.
This integrated approach reduces approval risk and supports smooth progression from design through to construction and final adoption.
Section 104 Sewer Adoption Agreements
Section 104 sewer adoptions allow new sewers to be adopted by the water authority once constructed to the required standards. CGS Civils manages the full technical design and submission process for Section 104 agreements, ensuring compliance with current adoption guidance.
We prepare adoptable drainage layouts, coordinate technical approvals, and support clients through construction, inspections, and final adoption.
Section 106 Sewer Connections
Where developments require connection to existing public sewers, Section 106 sewer connections are required. CGS Civils prepares the necessary designs and supporting documentation to facilitate approval, ensuring connections are compliant and appropriately coordinated with existing infrastructure.
This approach helps avoid conflicts, reduce risk, and support efficient connection approvals.
Section 98 Sewer Requisitions
Section 98 sewer requisitions apply where new public sewers are required to serve a development. CGS Civils assists with the design and technical submission process, guiding clients through water authority requirements and approval procedures.
We ensure proposed infrastructure aligns with site layouts, construction phasing, and future adoption standards.
Section 185 Sewer Diversions
Where existing public sewers conflict with proposed development layouts, Section 185 sewer diversions may be required. CGS Civils provides technical design and coordination to support diversion agreements, ensuring compliance with water authority standards while minimising disruption.
Our coordinated approach helps integrate sewer diversions seamlessly into the wider site design.
