Drainage Installation and Replacement
New drainage for a changed layout, a run that has failed beyond repair or pipework that was never suitable for the load are the usual triggers for this service. Set out the proposed change, where it will connect, any levels already known and the other services that may lie on the route. What is reported informs the scope; it is not a design.
Overview
New or replacement drainage has to be set against levels, the discharge point, services already in the ground, available access and how the building will be used.
Our full service catalogue, including every individual service, is available across every listed sector and location. For one site or several, we agree the scope, access and programme around the buildings concerned.
What the work can include
The scope can include assessing the route and connection, a defined installation or replacement, testing and the handover information. It names the route to install, the connections to make, the testing record to produce and what is supplied or tested at completion. Repairs elsewhere, specialist design, additional testing or replacement beyond the named sections are separate unless included.
At handover the client receives the installed route, the connections and the testing record, with any limitation, interface or outstanding action stated.
Important decisions
Before design or replacement is committed, the existing route and its condition must be established, because that drives what can be reused and what must be new. Fit that decision to the site's operating constraints and the client's approval route.
Before we visit
Provide site plans, the proposed layout, known connection points, ground or surface constraints, permissions obtained and how the site must keep operating during the work. Across an estate, identify each site and keep asset or area references consistent so findings from one installation are never merged with another.
Include the proposed layout, known connection points, other services on the route, levels and access limitations. Say what permissions are required and what surface or traffic reinstatement follows.
How the work proceeds
The existing arrangement is surveyed, the route and its interfaces defined, the work planned, the agreed sections installed or replaced and completion recorded. The handover gives the facilities manager the route, connections and testing record on which handback is accepted.
What affects cost and timing
Scope and price are driven by excavation, disruption to traffic or building users, service diversions, reinstatement, testing and connection permissions. On a managed site or estate, the operating window, access contact and shutdown constraints are needed up front.
Sector and property applications
Office, education, retail and industrial sites each shape how levels, connections, existing services and reinstatement are handled. The sector directory shows how the requirement varies by site type.
Local coverage
Sites in Northumberland, Tyne and Wear, County Durham and Tees Valley are covered, among them Berwick-upon-Tweed, Alnwick, Morpeth, Hexham, Newcastle upon Tyne, Gateshead, Sunderland, Durham, Darlington, Hartlepool, Stockton-on-Tees, Middlesbrough and Redcar and Cleveland. For estate work, keep each site's installed route, connections and testing record in its own file. Locations in full.
Frequently asked questions
Can new drainage connect into an existing connection?
Only once capacity, condition, levels, ownership and the intended discharge route have been checked. A connection that served the old layout is not automatically fit for a new one or a heavier load. Across an estate, track route, connections and testing record per site so the next decision is clear.
When does replacement make more sense than repair?
When the defect is widespread, the route or material is wrong, a repair would not last or the planned change needs a different arrangement. The assessment establishes which applies. Where occupants or operations are affected, agree access, shutdowns and retained-contractor interfaces before the work is programmed.
Is excavation unavoidable?
Not always. Some work can use existing accessible routes, but the method depends on depth, condition, connections, obstructions, ground and what sits on the surface. The completion record should state what was covered, what was not and what follow-up is needed.
What should the handover records contain?
The installed route and connections, sections tested or inspected, materials or assets included, limitations, reinstatement carried out and outstanding actions. On planned work, findings decide whether further installation, replacement or related remedial work follows.
Knowledge and guidance
The work rests on documenting the existing route and its condition before design or replacement starts, and the service assessment sets out what information is needed before the scope is agreed. On a managed site or estate, apply that alongside operating duty, access and the client's approval route.

Contact Black & White Facilities with the site or estate, the route to install or replace, the connections involved, any testing record held, other records and operating constraints. With that we set out how the work interfaces with the site and what it covers, leaving response time and outcome to be agreed rather than assumed.
