Drainage and Wastewater
Drainage Installation and Replacement
New drainage, failed runs, altered layouts or replacement of unsuitable pipework can justify this service. Describe the proposed change, connection point, known levels and existing services that may affect the route. A description of the symptom is useful evidence for scoping, but it is not a remote diagnosis.

Overview
New or replacement drainage must be coordinated with levels, discharge points, existing services, access and the intended use of the property.
What the work can include
The agreed scope can include route and connection assessment, installation or replacement scope, testing and handover information. The agreed scope names the installed route, connections and testing record and states what will be supplied or tested at completion. Additional repairs, specialist design, testing or replacement are separate unless expressly included.
At completion, the client receives the installed route, connections and testing record; any limitation, interface and the next action are stated.
Important decisions
Prepare the existing-route and condition information needed before design or replacement. Coordinate this choice with the commercial site’s operating constraints and client approval route.
Assessment and preparation
Before arranging the work, provide site plans, proposed layout, known connection points, ground or surface constraints, permissions and operating requirements. For a portfolio, identify each site and retain consistent asset or area references so findings can be compared without merging different installations.
Provide the proposed layout, known connection points, existing services, levels and access constraints. Identify permissions and any surface or traffic reinstatement required.
How the work proceeds
Survey the existing arrangement, define the route and interfaces, plan the work, install or replace agreed sections and record completion. At handover, the client can use the installed route, connections and testing record to decide the route, connections and testing handback.
Cost, timing and disruption
Scope and price are affected by excavation, traffic or occupant disruption, service diversions, reinstatement, testing and connection permissions. For a commercial site or portfolio, provide the operating window, access contact and shutdown constraints relevant to drainage installation and replacement.
Sector and property applications
Commercial offices, education, retail and industrial sites may require drainage installation and replacement to be coordinated around levels, connections, existing services and reinstatement. Use the full sector directory to place the site requirement in context.
Local coverage
We cover Northumberland, Tyne and Wear, County Durham and Tees Valley, including Berwick-upon-Tweed, Alnwick, Morpeth, Hexham, Newcastle upon Tyne, Gateshead, Sunderland, Durham, Darlington, Hartlepool, Stockton-on-Tees, Middlesbrough and Redcar and Cleveland. For portfolio work, keep the installed route, connections and testing record separate for each site. View all locations.
Frequently asked questions
Can a new drain use an existing connection?
Only after checking capacity, condition, levels, ownership and the proposed discharge route. An existing connection is not automatically suitable for a changed layout or load. For portfolio planning, track the installed route, connections and testing record separately for each site so the next service decision is clear.
When is replacement preferable to repair?
Replacement is considered where the defect is extensive, the route or material is unsuitable, repair is not durable or the planned change requires a different arrangement. The assessment must establish which applies. Where the work affects occupants or operations, agree access, shutdowns and retained-contractor interfaces before the activity is scheduled.
Will excavation always be required?
No. Some work can use existing accessible routes, but the required method depends on depth, condition, connections, obstructions, ground and surface constraints. The completion information should state what was included, what could not be completed and what follow-up is needed.
What records should be handed over?
They should identify the installed route and connections, tested or inspected sections, materials or assets included, limitations, reinstatement and any outstanding actions. For planned work, use the finding to decide whether further drainage installation and replacement or related remedial work is needed.
Knowledge and guidance
prepare the existing-route and condition information needed before design or replacement. The service assessment explains the information needed before the work is agreed. For a commercial site or portfolio, use this guidance alongside operating duty, access and the client approval route.
