SEPTIC Tank Survey in Ellesmere port
Septic tank and private drainage survey carried out at a residential property in Ellesmere Port, assessing the condition, connectivity and apparent operation of the drainage system.
The survey identified multiple displaced and open joints, indications that the septic tank may serve more than one property, and an outfall arrangement that could not be fully traced or verified.
Location: Ellesmere Port, Cheshire
Service: Septic tank surveys
Overview
We were instructed to carry out a septic tank survey in Ellesmere Port to assess the accessible private drainage network and investigate the septic tank arrangement serving the property.
The purpose of the survey was to understand the condition of the incoming drainage, establish how the system connected to the septic tank, identify any structural defects, and review the discharge arrangement as far as access allowed.
Private drainage systems can become more complex where tanks are located outside the property boundary or appear to serve multiple properties. In these situations, it is important to understand not only the physical condition of the drainage system, but also the likely ownership, access and maintenance responsibilities associated with it.
What we did
We carried out a CCTV drainage survey across the accessible pipework serving the property and traced the system towards the septic tank.
The survey included:
Inspecting accessible foul drainage runs
Assessing the condition of the incoming pipework
Identifying displaced and open joints
Reviewing incoming junctions within the network
Locating the septic tank
Assessing the outfall arrangement
Attempting to trace the downstream discharge route
Recording areas where further investigation was required
Several incoming junctions were identified within the line leading towards the septic tank, suggesting that the installation is likely to serve multiple properties. The septic tank itself was located on adjacent land outside the property boundary, creating additional considerations around ownership, access and future maintenance.
The Outcome
The survey identified multiple displaced and open joints throughout the inspected drainage pipework. These defects may allow leakage, infiltration and root ingress, increasing the risk of blockage and further structural deterioration over time. We recommended structural patch lining at the more significant defect locations where practicable.
The presence of several incoming junctions indicated that the septic tank likely forms part of a shared private drainage arrangement. However, the full network and total number of connected properties could not be confirmed during the survey.
Because the tank is located on neighbouring land, the arrangement also raises important questions around:
Ownership of the septic tank
Rights of access for maintenance
Responsibility for emptying and servicing
Liability for future repairs
How costs are shared between connected properties
The septic tank outfall was identified as a filter-bed arrangement. The construction of the filter bed prevented CCTV access to the downstream pipework, meaning the route, condition and final discharge destination could not be confirmed. As a result, compliance with the Environment Agency General Binding Rules remained unverified based on the evidence available during the survey.
We recommended further investigation, potentially including targeted excavation or drainage tracing, to establish the downstream discharge arrangement.
We also advised that the relevant property documentation should confirm the ownership and responsibilities associated with the shared system, including access rights, connected properties, maintenance arrangements and shared repair costs.
This project is a strong example of why septic tank surveys and private drainage investigations are valuable even where the system appears to be operating. Shared systems, off-boundary tanks and unverified discharge arrangements can create practical and legal considerations that are important to understand before future maintenance or remedial works are required.
