Pipeline Survey

What is Pipeline Survey?

A pipeline survey is defined as a method for assessing the existing conditions of stormwater collection and water distribution pipelines running beneath a city. A pipeline survey can estimate the extent of damage and deterioration in a pipeline and evaluate the need for repairs, replacements, or rehabilitation. With advancements in trenchless technology, it is possible to determine the condition of installed pipelines without excavation for visual inspection and repair. Regular pipeline surveys can help prevent failures by highlighting weak spots, cracks, and corrosion in the pipeline before they occur.

In the context of trenchless construction, it can be defined as a method of surveying a given land to determine the location, depth, and length of the pipeline running through that area before pipeline installation. This can be accomplished using geotechnical survey methods, GPS, and other related techniques. Conducting pipeline surveys is crucial during the installation of new pipelines to prevent cross-boring and other associated accidents.

Pipeline Location Survey

Pipelines are the most cost-effective and environmentally friendly means of transporting resources such as gas or oil. Thousands of miles of pipelines span the United States from coast to coast. Almost all Americans rely on these pipelines for their energy needs, prioritizing the safe construction and operation of the pipelines. Route surveys need to be conducted, topographic surveys need to be performed, and utility surveys must be undertaken to determine the most cost-effective routing for the pipeline. The surveys should be conducted in such a way that all surrounding details are taken into account. By coordinating the three types of surveys, it will be possible to identify where the pipeline can be easily routed at a lower cost.

If this careful consideration is not completed, the construction of the pipeline may face disruptions. Before construction begins, pipeline routes must be carefully selected to avoid specific sensitive areas while remaining economically feasible.

Objective of Sewer Pipe Line Project Survey

The sewer pipe project survey is conducted with the aim of installing appropriate sewer pipelines. The detailed survey conducted to properly establish sewer pipelines in a specific area is referred to as the sewer pipeline project survey.

This survey is carried out for the following purposes:
(i) Preparation of project estimates,
(ii) Verification of project feasibility and design creation,
(iii) Determination of possible alignments,
(iv) Understanding the geomorphology of the project area,
(v) Accurate implementation and evaluation of the project,
(vi) Analysis of economic expansion and decision-making.

Survey Operations Involved in Sewer Pipeline Survey

The survey operations related to the sewer pipeline project are as follows:

The following survey methods are generally used for sewer pipeline projects:

1. Topographic Survey: Topographic surveys are conducted to determine the actual location and elevation of the sewer line. This involves identifying the area’s topography, including natural and artificial structures.

2.   Geotechnical Survey: This survey is conducted to analyse the soil composition, strength, and other characteristics necessary for the installation of the sewer pipeline. It helps ensure the stability of the pipeline installation.

3. Underground Utility Survey: This survey is used to identify the location of existing sewer lines and other underground utilities. It helps avoid conflicts during pipeline installation.

4.  Hydrological Survey: This survey is utilised to analyse water flow within the sewer system, precipitation drainage, and other water-related components.

5.  CCTV Survey: This survey is conducted using CCTV cameras to monitor the internal condition of the sewer pipeline, helping to identify any deterioration or blockages in the sewer line.

By properly utilising these survey methods, accurate planning and implementation of the sewer pipeline project can be achieved.

Reconnaissance Survey

This is a rapid survey method for the entire area and requires lightweight equipment. Instruments such as a prismatic compass, tape measure, and hand level are used in this survey. With the help of this type of survey, a suitable route for the sewer line is selected, and the appropriate route is reported to the engineering authorities. The following information is collected to inform the authorities:
(i) Soil type and drainage condition.
(ii) Potential suitable alignments.
(iii) Descriptions of important areas, towns, rivers, hills, etc.
(iv) Geomorphology of the area.
(v) Maximum flood elevation.
(vi) Availability of construction labour and materials.
(vii) Land value for acquisition.
(viii) Time for completion of construction.
(ix) General slope of the mountains for hilly areas.
(x) Amount of elevated and low-lying areas in the region.

Description of the Preliminary Survey for Sewer Line

The detailed survey conducted along the selected path in the reconnaissance survey using the necessary equipment for small sections is called the preliminary survey. The commonly used instruments include transit theodolite, level, tape measure, chain, plane table, tekometer, hand level, etc.
The survey is carried out using the following methods:
(i) An open traverse survey is conducted along the central line of the small section, and stakes are placed at each traverse station.
(ii) Stakes are placed every 15 metres along the central line of the alignment, and staff readings are taken at each stake.
(iii) Cross levelling is done every 30 metres along the alignment.
(iv) Detailed information of the small section is surveyed using a plane table survey and is drawn on the map.
(v) After completing the fieldwork, a topographic map and a contour map of the small section are drawn. The information obtained from these two maps is used to plot the final alignment line on the map, which is later established in the field.
(vi) When plotting the final alignment, it is important to ensure that changes in the alignment are minimised, and the proposed slope is compatible with the terrain slope. The alignment should be such that the amount of earth cutting and filling is approximately equal. For drawing longitudinal sections, the horizontal scale should range from 1 inch = 100 feet to 400 feet, and the vertical scale should be from 1 inch = 10 feet to 50 feet. The contour interval is generally 5 feet; however, for urban surveys, it can be 1 foot, and in the case of steep sloping terrain, it can be up to 10 feet.

 Description of Final Location Survey for Sewer Line

The survey conducted to establish the final alignment line drawn on the preliminary survey map in the field is called the final location survey. The following methods are employed for this survey:
(i) A north line is established at the starting point, and its chainage is considered zero.
(ii) Stakes are placed at intervals of 10 to 30 metres along the central line, and pillars are placed along the boundary line to indicate the right-of-way.
(iii) Other measurements from the preliminary survey map are scaled and established in the field.
(iv) Stakes are placed at the points of tangency of the curves.
(v) Measurements for earth cutting and filling are taken after cross-sectioning.
(vi) Necessary information is collected for design and estimation purposes.

Description of Construction Survey for Sewer Line

This type of survey provides detailed information for the project.
(i) All stakes along the alignment are inspected, and any missing stakes are measured and located. The levels of all stakes are checked.
(ii) All completed work is recorded in the account books, and the accounts for materials and labour are updated at regular intervals to allow the contractor to receive progress payments during the project.
(iii) The condition of the sewer’s invert level is checked using a boning rod.
(iv) The locations of manholes, drop manholes, lamp holes, leaping weirs, flushing tanks, inverted syphons, etc., are marked by placing stakes.

What Does Class Location Mean in Pipeline Inspection?

In pipeline inspection and surveying, there are four different classes, all of which are related to population density and how suitable (or unsuitable) a specific area may be for pipeline construction. Population density is determined by counting the number of buildings within 660 feet of a mile of the pipeline. A detailed topography survey must be conducted to identify areas with low and high populations, which will help in determining the pipeline’s placement. This will ensure that it is economically feasible.

Additionally, a pipeline Survey is a method of Evaluating. The Present condition of a Tube that runs under the earth’s surface or surveying for pipeline construction.

Pipeline survey occurs for different Tube-like oil, gas, water, Evaluating line, etc.
