Precise Aqueduct Detection

Published on by in Technology

Does anyone know a precise method for detecting aqueduct trails of buried aqueducts with sinuous trails?

We need very precise detection because the building permits are required in some areas where aqueducts exist. We have used various methods but none have been precise (There were differences of 2-5 meters).

  1. We are running a WWTP with a flow of 6 m3/s .The resulting sludge from process  is used in the digesters.I read about your product SOLUTEK and would like to know how it influences the quality of sludge used in digestors.It is known that this product must have a certain load( including volatile products).


    I want to know if the use of SOLUTEK will influence the efficiency of the digestion process.Thanks in advance for your answer.

    1. Anghel.......quite simply, the use of Solutek increases efficiency. One of our company products is a small biodigester which we call RAPAD. We add Solutek to the feedstock before it enters the digester... we get increased performance. Solutek is 100% fully organic and biodegradable,no matter what type of bacteria are present Solutek will provide the right conditions whereby the native  bacteria will massively multiply over just 24 hours..By the way, we also remove sludge from systems ... but it takes some months for the sludge to be consumed.

      My email is: pettman@soleco-technology.com   if you would like to have a chat.

  2. Dear every one ​thanks for answering to my ​question

  3. In soil surveys I've used aerial photography which can show many underground features. The best I've seen are Infra red aerial shots.  Green vegetation is reddish, wet soils are dark and underground aqueducts which are near the surface can be seen by the outline of the structure . There were 2 different Infrared films,, near IR and far IR films available when I used them/

  5. I understand that you need reliable tracing equipment.  Radiodetection.com offers a variety of tools.  The material of the pipe determines the best detection technique.  Basically, you put a signal on the pipe (eg. at a valve) and then trace the signal with a sensor.  The type of signal is usually radio waves, sometimes acoustic.  You can also put a sonde in the pipeline.

    I have used the radio signals and it works quite well with cables and metal pipes.

    1. Many thanks for your answer ,I don't have much information in this area and I apologize, but  I come back with a question:when you say "you put a ​signal on the ​pipe " it means digging or put  above the buried  pipe (we have 200 Kilometers of aqueducts)?

  6. There are various kinds of methods and techniques for water leakage detection from buried aqueducts. Most of them are costly and time consuming while Water companies need to identify leakage quicker than conventional approaches with lower cost and also cover larger areas. The possibility of locating water leakages evaluated in the study area using satellite remotely sensed data. To detect pipeline leakage, the Landsat 8 satellite image processing such as producing a normalized difference vegetation indices (NDVI) map and an NDVI-based classification can be used. In addition, the analysis of soil moisture enabled known leaks to be highlighted and differentiated from their immediate surroundings. The outcomes emphasize the contribution of remote sensing techniques to the early detection of leakages by such free medium spatial resolution satellite images. These techniques are easy to be implemented for wide coverage area, especially in the studied area.

    1. Thanks a lot  for your answer.In the arid regions the vegetation index and the humidity of soil are very important indicators but in our case is not applicable vegetation index.

      I will seek more information about this solution

      Best regards.

  7. Try CCTV with linear measurement tracking. It will convey distances & angles accurately.

    Another option, Cavity Monitoring Laser. I've used for ovality of pipes. It connects to surveying software giving precise measurement, vision & data print out plus much more.

  8. Anghel.....geological surveys ... look at the LANDSTAT Satellite surveys... they are precise and available.

    Take a look at our brochure as well.

    Stay safe,

    Hugh.
