Manhole Surveys

Visual inspection, measurement, location and recording of manhole and inspection chambers can be provided in accordance with all current industry specifications.

CSO Surveys

Full CSO surveys with information provided in a range of options to suit client requirements. Surveys can include short and long term flow surveys, CCTV surveys of associated pipework and accurate GPS location.

Pumping Station Surveys

We offer full Pumping Station surveys providing detailed information on DWF/Pumping capacity and levels for pump stop/start operation and high level alarm. Results can be produced in a variety of formats to suit individual client needs.

Section 24 Drainage Studies

Using a range of techniques we specialise in the survey of previously unmapped public and private sewers to determine asset ownership for sewerage network operators.

Sewer Mapping

Location, identification and inspection of sewerage networks and associated structures to update existing water company records.

Multi Solutions

We can provide asset surveys to meet the specific needs of our clients, from a single survey to a complete site management package. We deliver a complete record of all existing site assets and drainage features which can be incorporated along with CCTV footage and manhole surveys.

High Quality Presentation of Asset Surveys

Surveys can be presented on CD or DVD or sent via email in clear and easily understood formats in line with client requirements.

Pinpoint GIS Asset Management

The Group’s businesses’ advanced survey and GIS mapping solutions enables clients to manage their drainage assets with pinpoint accuracy. Using state of the art handheld devices with GPS positioning and ordnance survey mapping, together with our unrivalled survey expertise, we can build an accurate profile of your drainage system, its condition and the required action areas.

This information can be supplied electronically to allow you to develop prioritised and well planned maintenance schedules to address key issues including:

1. Local Authority: Mapping and highlighting of defective drainage. Prediction of silt levels for efficient cleaning. Auditable data to back up cleaning.
2. Highways Agency: Recording data in line with HADD AMS, surveying above and below ground drainage and data validation.
3. Facilities Management: Network asset control and monitoring, KPI monitoring through ground level data collection, Health and Safety auditing.
4. Civil Engineers: Recording detailed drainage data within AutoCAD. Integrating defect data into as built plans for accurate repair.

All of the data to be linked with the assets is collected and merged at ground level so there is no chance of error. Data is sent wirelessly to our GIS server in the office, which collates the relevant information. This information is compiled in line with our various contracts and exported to the client with minimal interaction. The result is highly accurate and detailed data.

Flow Monitoring and Asset Data Collection

We offer the very highest standard of Flow and Load Surveys. Using the latest flow monitoring and sampling equipment, valuable information is provided to clients about their systems hydraulics, reaction to rainfall events, possible seepage, infiltration and pollution.

We use the latest version of SASS, a suite of computer programs, for checking, analysing and maintaining the large volumes of data generated by sewer-surveys. SASS provides the facility to transfer data from portable logging devices to its internal database. This data is then checked for inaccuracies, which can then be corrected or eliminated. Depth, velocity and flow rate of sewage are then calculated from raw depth and velocities, taking into account the site checked measurements.
