Gullies and Surface Water

A clear gully does not prove the downstream system has capacity or that falls and inlets are correct; rainfall patterns and the receiving route matter.

The agreed scope can include gully clearance, visible condition checks, surface-water route investigation and defined repair or replacement options. The agreed scope names gully points, flow results and the surface-water route 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 owner or agent receives gully points, flow results and the surface-water route; any access limitation and the next job decision are stated.

Separate local inlet clearance from wider surface-water investigation. Relate this choice to the property condition, access arrangement and owner or agent’s next instruction.

Before arranging the work, provide site plan, affected areas, rainfall timing, gully locations, access, traffic or pedestrian constraints and known connections. For a managed or shared property, identify the owner, occupier, managing agent and person authorised to approve access or additional work.

Provide the affected gully locations, rainfall or overflow history, site plan and access restrictions. Include traffic or pedestrian controls for yards and entrances.

Inspect the surface-water points, clear agreed restrictions, test flow where practical, record defects and recommend targeted follow-on work. At handover, the owner or agent can use gully points, flow results and the surface-water route to decide whether inlet clearance or downstream work is needed.

Scope and price are affected by number and type of gullies, silt or debris, traffic management, access, disposal and downstream investigation. For a property job, provide the access arrangement, occupier or agent contact and any restriction on use relevant to gullies and surface water.

Owners, landlords, managing agents and occupiers may need gullies and surface water scoped around yard access, rainfall effects and pedestrian or traffic movement. The sector directory provides the wider property context.

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 a property job, send the address with gully points, flow results and the surface-water route and the access or responsibility contact. View all locations.

Cleaning removes the immediate restriction, but overflow can continue if the outlet, downstream capacity, pipe condition, levels or rainfall exceeds what the arrangement can manage. For a property job, confirm gully points, flow results and the surface-water route with the owner or agent before work is arranged.

Usually not. Gullies commonly serve surface water, while foul drainage serves wastewater; the actual connection must be confirmed from plans or inspection rather than assumed. Access through occupied rooms, shared areas or neighbouring land should be agreed with the occupier or agent before the visit.

Not always. Clearing an inlet can restore local flow, but persistent flooding may involve falls, downstream restrictions, capacity or the wider surface-water route. The job decision should distinguish immediate making-safe work from a later repair, replacement or improvement instruction.

Provide clear vehicle or pedestrian access, gully locations, traffic restrictions, nearby drainage plans and any need to work around occupied yards, entrances or deliveries. At handover, give the owner or agent the property-specific record, outstanding action and any restriction on use.

Read what causes recurring drain blockages to separate local inlet clearance from wider surface-water investigation. Use the service assessment to apply that guidance to the property or site. For a property job, use this guidance alongside condition, access and the owner or agent approval route.

For gullies and surface water, use Drainage and Wastewater, Drain Cleaning and Maintenance, CCTV Drain Surveys, Planned Preventative Maintenance. Browse all services, maintenance, projects, sectors and locations.

Contact Black & White Property Services with the property address, owner or agent contact, gully points, flow results and the surface-water route, access information and desired result. We can then define the job scope without assuming a response time or outcome.
