Why Cellular GIS is Essential to Stopping Fuel Explosions

This text is an element 1 of a 2-part sequence on Cellular GIS and cross bores.

Cross bores happen when a pure fuel line is unintentionally drilled by present underground infrastructure – like a sewer pipe. They’re an enormous drawback for utilities and a threat to public well being due to their function in pure fuel explosions.

Nonetheless, new mapping know-how – Cellular GIS – can assist cut back the dangers of cross bores by reducing prices and rising velocity in utility integrity administration.

The Cross Bore Drawback within the US

Estimates place the variety of cross bores in america at as much as 1 million.

The variety of harmful incidents is harder to pin down, however between 2000 and 2010 there have been 18 cross bore-related explosions, averaging roughly two incidents per 12 months. Steps at the moment are being taken to stop new cross bores.

Nonetheless, the one technique to stop deaths from present ones is to manually examine each size of sewer pipe within the nation. The Cross Bore Detection and Mitigation was created to perform this immense process.

Utility corporations personal the dangers associated to cross bore incidents and thus the duty for stopping them. Information sharing happens industry-wide with the frequent objective of serving to everybody develop the very best cross bore program potential.

Nonetheless, there’s a notable lack of standardization within the instruments and methodologies carried out to perform discover and resolve cross bores.

Within the Frequent Floor Alliance’s 2018 Expertise Report: Expertise Developments & Gaps in Underground Security, the group identifies 13 areas associated to mapping and GIS that want technological options:

1. Correct mapping of underground services
2. Mapping close to misses – accumulating and enabling the usage of this information
3. Mapping harm areas
4. Enabling information sharing
5. Figuring out services presently not mapped, recorded, or identified
6. Making the GPS mapping know-how usable by development crews
7. Integrating GPS mapping and GIS in actual time and workflow
8. Utilizing routine upkeep alternatives to GPS-record belongings
9. Creating “open” GIS methods/higher sharing of the info
10. Mapping belongings by mainline inspections and associating location with video
11. Offering higher GPS sign energy in city canyons and beneath tree cowl*
12. Offering software program evaluation for high quality suggestions about GPS coordinate assortment
13. Growing requirements for GPS information high quality

This weblog proposes the implementation of Cellular GIS to deal with 12 of the 13 points above – serving to to avoid wasting lives by making a quicker, cheaper legacy cross bore course of.

Objectives and Challenges of Cross Bore Applications

A typical legacy cross bore program, one which focuses on discovering and repairing present cross bores, comprises the next components:

1. Danger evaluation: Decide the danger of a cross bore incident and prioritize areas for inspection by analyzing parcel and plat information.

   Danger evaluation includes sorting, organizing, and analyzing large quantities of knowledge associated to a broad bodily location. The outcomes should then be organized in a method that’s simply accessible and comprehensible for the following step. The heavy quantity of data-related work is time-consuming and useful resource intensive.

2. Inspection Packet Project: Particular person inspection groups should take their project, run a sewer scope for every parcel, and exactly file the outcomes.

   Every area group and every contracting firm should develop their very own technique of recording information based on the supplies offered to them by the utility firm. These strategies usually depend on a mix of PDF information and paper and require data to be copied by hand a number of instances. The dearth of standardization and digitization introduces a large alternative for error.

3. Parcel Inspection: The contractor should take the inspection packet project from the utility and successfully distribute the work to their area groups whereas precisely monitoring the progress.

   Many potential points come up on this step, because it’s the primary occasion the place directions are handed by a number of folks. The problem for the utility firm is ensuring their packet project is definitely understood, whereas the problem for contractors is ensuring they correctly perceive the project and might successfully optimize their work and inspection routes. If wires are crossed right here, inspections received’t occur correctly and work will have to be redone.

4. Information Seize: Successfully switch inspection information from the sphere to the utility firm.

   Transferring this massive amount of knowledge leads to a lot of ache factors. Video proof is usually despatched in DVD format, which makes it extremely difficult to evaluate rapidly. Map information should even be compiled and despatched off in a method that coordinates with the video information. The mixture of bodily media and digital paperwork results in a gradual and disorganized information switch course of that may severely delay schedules and end in misplaced information.

5. QA/QC Evaluate: It’s the duty of the utility firm to confirm the info despatched to them by their contractors, guaranteeing it meets accuracy and requirements pointers. The QA/QC evaluate course of exists as a failsafe step to be sure that no cross bore goes unnoticed. If the utility firm finds an issue, the knowledge should be despatched again to the contractor to be reviewed and re-inspected.

   This step could be a important time drain. With no standardized strategies of knowledge assortment and no organized reporting, error charges may be fairly excessive. Larger error charges imply important delays as reviews should be despatched backwards and forwards for a number of inspections.

6. Cataloging: As soon as the info has been verified, it should be transferred into the utilities’ most well-liked format of file, distributed to the suitable groups, after which saved for future reference.

   Cataloging introduces extra room for error, as information should be transcribed as soon as once more. It additionally creates one other bottleneck within the cross bore course of as a result of it’s an costly, guide effort restricted by the variety of folks dedicated to the method.

In laying out the steps and challenges of a legacy cross bore program, a transparent theme emerges. The utility {industry} wants a standardized, easy system of file that maintains a single supply of fact from the start to the tip of the method. Just one class of software program comes near addressing these wants: Geographic Info Programs (GIS).

The Position of GIS in Legacy Cross Bore Applications

GIS refers to a broad group of knowledge administration methods that manage data by location – two well-known examples are Google Earth and ESRI.

GIS know-how usually encompasses a set of highly effective instruments for a wide range of superior information functions. Sadly, the complexity inherent to any such software program usually limits its accessibility to solely professionally educated personnel.

For legacy cross bore work, the essential perform of GIS software program is to allow a utility to correctly doc inspected sewer traces on a map of their territory. In an excellent world, GIS software program can be the muse of a legacy cross bore program, from figuring out and assigning work, all the best way to cataloging inspected parcels.

Sadly, most GIS software program is just too cumbersome for use effectively by every particular person concerned within the cross bore mitigation and detection course of. So, as a substitute of changing into a vital instrument for carrying out work rapidly and precisely, GIS turns into an inconvenient requirement of the info storage course of.

If utility corporations are ever going to successfully discover and resolve each cross bore occasion throughout the hundreds of thousands of miles of sewer infrastructure in america, they’ll have to streamline the usage of GIS know-how.

The {industry} should transcend the present capabilities of recent Desktop GIS software program, and work to create a map-based workflow that permits flawless communication and information switch between the workplace and the sphere.

Going Past Desktop GIS: An Finish-To-Finish Strategy to Legacy Cross Bores

The lacking piece of recent GIS is its lack of ability for use by everybody concerned within the cross bore detection and mitigation course of.

This roadblock exists for a lot of causes:

• Information buildings in GIS usually are not optimized for cell units or cell networks.
• GIS requires costly and highly effective native {hardware} to run.
• The person expertise of GIS software program is advanced, requiring years of coaching to grasp.
• Licensing buildings are cost-prohibitive and restrictive, significantly in relation to area groups.

These are the weaknesses of desktop GIS – highly effective, but advanced know-how put in on a pc, which doesn’t translate effectively to the sphere.

To transcend GIS, the utility {industry} must implement a map-based system that doesn’t simply retailer geospatial information, but additionally optimizes the method of cross bore detection and mitigation itself. In different phrases, utilities want Cellular GIS.

Efficient Cellular GIS offers:

• Cellular-first design with information buildings created for supply over cell networks.
• Cloud-based structure that eliminates the necessity for highly effective native {hardware}.
• A easy person expertise that lets anybody decide it up and use it immediately.
• An adaptive license construction that’s versatile sufficient to fulfill the wants of scaling with area groups.
• A characteristic set that’s nonetheless sturdy and highly effective sufficient to fulfill the large information necessities of cross bore mitigation and detection.

With these items in place, a legacy cross bore program may very well be simplified and streamlined into a number of steps that each one happen in a single system:

1. Add or choose the realm that must be inspected.
2. Assign the realm to a chosen area group.
3. The sector group marks their inspection instantly into the system from the sphere.
4. Maps and all related information are immediately obtainable for evaluate by the utility.
5. As soon as reviewed, the method is completed. There’s no have to switch to a different system of file.

If the {industry} can agree upon a standardized system and course of, it may possibly work collectively to assist cross bore detection and mitigation evolve to be even quicker and extra streamlined.

Why Make investments the Time and Effort to Procure Cellular GIS?

In the end, legacy cross bore packages are about saving lives.

With estimates of cross bores occurring at a price of .4 for each mile of pipeline, and with 2.5 million miles of pipeline in america, this drawback must be tackled as swiftly as potential.

In a superb 12 months, utilizing present requirements, a utility firm can doubtlessly clear round 35,000 addresses. Extrapolated out, meaning clearing a big territory of 5 million addresses would take virtually 150 years!

The arduous fact is that with the present course of, will probably be inconceivable to ever absolutely full a cross bore program in an appropriate timeframe. With cross bore incidents occurring at a price of about 2 per 12 months, that’s a major variety of lives in danger.

If legacy cross bores are ever to turn into a factor of the previous, and the danger of harm and loss of life eradicated, the {industry} has to determine the way to make the method quicker and cheaper.

A brand new methodology of GIS is the mission-critical process to perform these goals; it provides probably the most alternative to advance the objectives from each a short- and long-term perspective.

Quick-Time period Advantages

Finish-to-end inspection velocity may be considerably elevated by simplifying time-consuming duties and eliminating redundant steps within the project, inspection, and evaluate processes. 

As velocity will increase, the price to examine a parcel comes down, permitting groups to examine a broader space for a similar quantity of price range. Moreover, because the variety of methods concerned declines, the price range spent to take care of them may be redirected towards different bills, akin to assigning extra inspection packets.

Lengthy-Time period Advantages

The long run is the place transferring past Desktop GIS will get actually thrilling. As soon as inspection information begins to build up in a single system, the chances of what you are able to do with that information enhance exponentially.

Probably the most thrilling prospects contain the potential for predictive evaluation. With sufficient inspection information, utilities can start to mechanically establish areas with a excessive threat of cross bores, prioritize them based mostly on their inside standards, after which create a predictive schedule for when their whole service space shall be freed from legacy cross bores.

Modernizing the GIS requirements of legacy cross bore packages is the important first step in eliminating latent cross bores nationwide. And not using a strong basis, progress will proceed to be gradual and expensive, making it just about inconceivable to do away with this risk.
