Truro is Cornwall's administrative and commercial centre, and its drainage system carries the load to match. The city's Georgian townhouses along Lemon Street and the surrounding residential streets sit above a network originally built to serve a fraction of the current demand, while the convergence of the River Allen and River Kenwyn through the centre creates a high water table that places persistent pressure on below-ground pipework. The mix of listed buildings, Victorian villas, modern apartments, commercial premises, and public buildings across a compact city footprint means drainage faults can affect multiple properties quickly. A CCTV drain survey records the condition and layout of the system beneath your property and identifies defects before they escalate. Clear Stream Drainage Solutions surveys across Truro and the surrounding TR1 postcode with no call-out fee, no diagnostic charge, and a fixed price agreed in writing before we begin.
Few settlements in the South West match Truro's drainage complexity. The city centre sits on three culverted rivers, the Kenwyn, the Allen, and the Tinney, buried by Victorian engineers, and every central drain run threads around these hidden watercourses. The Georgian frontages on Lemon Street, the listed terraces on River Street and Quay Street, and the Victorian commercial buildings of Boscawen Street rely on original clay pipework now carrying the load of properties converted into flats, offices, and short-term lets. Restaurants and bars around Lemon Quay and the cathedral quarter discharge fat and grease at volumes the original system was never built for. Out toward Tresillian, Probus, and Ladock, properties are almost all on private septic tanks, with soakaway performance constrained by clay subsoils and killas slate. None of this is reliably documented in property paperwork. A CCTV survey is the only way to know what is genuinely in the ground.
A drainage survey is something you book in advance, not something you call out in a crisis. The situations below are where Truro property owners get the most value from one. If any apply to you, a survey is worth booking.
Before You Buy A Property
Recurring Faults At The Same Location
Extensions And Build Over Approval
Insurance, Legal, And Subsidence Evidence
Unexplained Damp, Smells, Or Garden Patches
Landlord And Portfolio Documentation
A survey is only as useful as the report it produces. Our engineers work to a structured process that delivers evidence usable by lenders, solicitors, insurers, and Building Control officers, not just a memory stick of raw footage.
A waterproof HD camera is fed through the drainage system from existing access points, with no excavation. Footage is reviewed live so defects can be discussed on-site as they are found. Crawler cameras are used where larger-bore commercial pipework requires them.
We trace the full layout of the pipework, identify every access point, and confirm where private responsibility ends and the public sewer network begins. In Truro, where private runs frequently cross neighbouring opes, courts, and back lanes, this part of the survey is often the most valuable.
Every cracked joint, displaced section, root mass, scale deposit, misconnection, and pitch fibre deformation is logged, located, and graded. You see immediately which defects require attention and which can be left for ongoing monitoring.
The deliverable is a full report containing HD video, still images of each defect, a drainage plan, defect grading, and recommendations. Format is suitable for direct submission to solicitors, mortgage lenders, insurers, and Building Control.
The single most expensive blind spot in a property purchase is the drainage system. A standard building survey does not investigate it. A pre-purchase CCTV survey closes the gap before you exchange, and the cost is small relative to what it can reveal. Buyers use the report to negotiate the purchase price down to reflect defect repair costs, require the vendor to complete remedial work before completion, or pull out of a sale that would have left them with a major bill. In Truro this matters most for the city's Georgian and Regency stock, listed properties where any repair faces planning constraints, conversion flats where shared soil stacks complicate ownership, and rural homes on septic systems where soakaway condition is invisible without inspection.
Build-over surveys are required wherever new construction sits within 3 metres of a public sewer. In Truro this requirement is unusually common, because the historic core is densely served by South West Water assets and the city sees a high volume of extension, conversion, and basement work in the conservation areas around Lemon Street, the cathedral, and the river. Our build-over surveys document the location, depth, and structural condition of the affected sewer, identify any defects that must be addressed before construction begins, and provide the evidence Building Control and South West Water require before issuing approval. Reports are produced to the format and standard those bodies expect.
What We DoThe survey evidence supports whatever action is needed: targeted repair, ongoing maintenance, pre-purchase due diligence, or regulatory compliance. Across the Truro area we work with homeowners, buyers, listed building owners, landlords, lettings agencies, solicitors' and accountants' offices, dental and medical practices, restaurants, pubs, cafes, retail premises, schools, churches, developers, and property management companies.
Our team clears blockages quickly and safely, restoring full flow and preventing further damage to your system.

A clear answer on ownership is one of the most practical outcomes of a Truro CCTV survey, and one of the most common reasons homeowners book one. The principle is straightforward. Pipework inside your boundary, including the lateral connection running out to the boundary line, is yours to maintain and repair. Once that pipe joins a shared sewer carrying waste from multiple properties, responsibility transfers to South West Water. Truro complicates this in ways most other Cornish towns do not. The medieval street layout means private drains routinely cross beneath neighbouring opes, alleys, and courtyards before connecting to a public sewer, and the culverted rivers beneath the city centre intersect with sewer runs in patterns no deed plan accurately records. Our survey establishes the actual layout, identifies the boundary point, confirms which sections belong to you, and provides the evidence needed to escalate any public-sewer fault to South West Water. For rural properties on septic systems toward Tresillian, Probus, and Ladock, the entire network is yours, and the survey produces a complete map of what that means in practice.
We agree a fixed price before any work starts, with no call-out fee and no diagnostic charge. Standard residential surveys typically fall within the range buyers and homeowners would expect to pay locally, with the exact figure depending on property size, number of access points, and the level of reporting required. You have the cost in writing before we book the appointment.
Most residential surveys take one to two hours on-site. The written report and footage are usually delivered within a few working days, formatted for sharing with solicitors, lenders, or insurers as needed.
Most high-street lenders do not require one as standard, but many request a survey when the main building survey flags drainage concerns, particularly on older properties. A significant proportion of Truro buyers commission one voluntarily as due diligence, especially on listed and period stock.
If significant defects are identified, the report and footage give you documented evidence to renegotiate the purchase price, require the vendor to complete repairs, or withdraw from the purchase. We provide the evidence; the negotiation sits between you and your solicitor.
If the proposed structure sits within 3 metres of a public sewer, a build-over survey is normally required for South West Water and Building Control approval. We handle build-over surveys regularly across Truro and produce reports to the required standards.
Yes. We carry out full septic tank surveys, soakaway investigations, and CCTV inspections of private drainage across the rural areas around Truro, including pre-purchase surveys for buyers of rural homes.

If a fault needs immediate attention, we discuss the options with you on-site. In most cases we can quote and address the issue on the same visit, with the cost agreed in writing before any work begins.
