SEWER CCTV Guidebook

Sewerage systems are essential to maintain a high standard of public health. In Singapore, it is also an important part of the “Water loop” to reclaim our precious water resources. To keep the sewerage system functioning well, it is important to ensure that sewers are in good condition and pipe deterioration and damages are identified early and rectified. This is done primarily through CCTV assessment of sewer condition.

This Sewer CCTV Guidebook (SCG) is intended as a guide on registration with PUB for CCTV contractors and the standard procedures of CCTV creation and submission.

This 2017 edition of SCG incorporate changes over the years to address new technical challenges and emerging issues facing the industry. It incorporates guidelines on a new online submission system developed based on feedback from the industry. The new system will manage the whole life cycle of sewer CCTV from recording to submission, processing and finally archival in a shared “cloud” database. This has done away with costly production of DVDs and hardcopy submissions by contractors and will result in much efficiency gains, improved operations and planning and cost savings to both contractors in the sewer CCTV industry and PUB.

PUB began registration for sewer pipelines’ CCTV contractors from June 2012 and from 1 Jan 2013, only registered contractors were permitted to conduct CCTV inspection works. Members of the public have been informed to use only registered CCTV contractors as reports submitted by unregistered contractors to PUB will be rejected. This effort aims to ensure the safety of CCTV inspection in sewers, improve the standard of sewer assessment/reporting and prevent malpractices.

Registered CCTV contractors shall fulfil the following roles:

1. Have sufficient qualified and competent site staff to carry out sewer CCTV and report condition of sewers correctly and accurately;

2. Have CCTV equipment that produces CCTV that meets the submission requirements; and

3. Submit CCTV condition assessment to PUB on behalf of client’s doing work that affect public sewers.

Registered CCTV contractors shall:

1. maintain an impartial and professional responsibility to reflect the true condition of the sewer assessed. Any falsification of CCTV records and/or collusion with any party to not reflect the true condition in the sewer assessment or use fabricated CCTV records will result in action to terminate the registration of the contractor;

2. ensure the safety of his workers at all times when working in the sewer environment by abiding with all conditions of entry into confined spaces of the sewerage system and all governing Bizsafe requirements; and

3. safeguard the sewerage system and maintain the flow and operation of the sewers at all time while carrying out CCTV operations. It is an offence for any person to carry out works in the public sewerage system without PUB’s approval.

Any CCTV contractor who wishes to register with PUB must meet the requirements on BizSafe Certification and have competent staff as set out in part 5 and 6 respectively. The Registration form and list of documents required are shown in in Annex A. Successful applicants will be listed on PUB’s website at www.pub.gov.sg. The registration is valid for three years and will lapse automatically unless renewed. Registration renewal shall be made one month before the expiry of the validity period.

All applicant/contractor company must possess at least BizSafe Level 3 Certification awarded by Workplace Safety and Health Council (WSHC) or equivalent.

The applicant shall provide details of qualified staff both for the sewer condition assessment by CCTV and site supervisors to carry out the works in the sewers. Please note that staff whose name is submitted for registration must be employed full-time and cannot be employed by another company even if the companies are related (e.g. subsidiary, holding company). All applicants/contractors must employ one or more competent staff who possess the following certifications:

1. Certificate of Proficiency in Sewer & Manhole Cleaning; and

2. Either one of the following:

   • Certificate of Competency in Water Research Company, plc UK (WRc) Sewer Pipeline Assessment and Certification Course (conducted by VSEA Engineering Solutions Pte Ltd);

   • Certificate of Proficiency in Sewer Pipeline Assessment Certification Programme conducted by SgSTT for both Part 1 on CCTV Inspection of sewer and Part 2 on Interpretation of CCTV videos and preparation of Reports;

   • Workforce Skills Qualifications (WSQ) on Certified Used Water Collection Technician

PUB may de-register or suspend the registered contractor for a period of up to 12 months if the contractor fails to meet the requirements set out under the Terms of Registration, or if the contractor commit any of the following:

1. contravenes any Safety Acts and the Sewerage & Drainage Acts and regulations while carrying out the CCTV inspection works;

2. fails to submit Form B (Application to Work in Public Sewerage System);

3. submits inaccurate/false CCTV inspection reports to PUB.

PUB may publish the names of the de-registered/suspended contractors in the PUB website. The contractor will only be allowed to re-register with PUB after the suspension is lifted.

Registered contractors are required to advise PUB immediately of any changes in its management status, address (mailing and email addresses) or any other pertinent change of particulars in writing and accompanied by copies of supporting documents.

The following officers will help provide clarification on registration matters:

• Mr. Qin Yihuai (QIN_Yihuai@pub.gov.sg) or

• Mr. Wong Kin Wee (Wong_kin_wee@pub.gov.sg)

The current list of PUB registered CCTV contractors can be seen in PUB website: https://www.pub.gov.sg/usedwater/registrationofcctvcontractor

From 1 Oct 2017, all PUB registered CCTV contractors will be required to submit their CCTV videos and reports using the new online sewer CCTV Management System at the website at https://www.sewercctv.pub.gov.sg/login.

What the new online system means to you:

1. Cost savings

   With online submission, there is no need to print your Sewer Assessment Reports or create DVDs of the CCTV or mail them to PUB. All these will be created and submit online at no additional cost to your initial creation of the CCTV record in your CCTV recording system.

2. Convenience

   You will be able to make online CCTV video and report submissions any time and from any remote site location with internet access, as and when the CCTV record and condition is assessed or at your own convenience in your office subsequently.

3. Faster Response

   Your submitted files will be auto-validated by the system. The system will tell you what is lacking if it fails the validation test. PUB having the same online access can start to process your submission once it is validated.

4. Improved experience

   With an online management system, you can view all CCTV submissions made by you and receive instant notifications, as soon as your submission has been reviewed by our staff. You will be able to view our comments, as well as made re-submissions for the rejected sections only.

How to start using the online CCTV submission system?

A step-by-step document has been prepared, to facilitate you in using the website. You may refer to the details of each section in the Annex G.

General Requirements

1. In the CCTV report, descriptions of defects and abnormalities in the manholes and sewers shall be described fully. Defects’ classification shall be presented in accordance with the WRc/WAA "Manual of Sewer Condition Classification" 5th Edition or the latest edition. Guidance notes on WRc defect classification is provided in Annex B. Please refer www.wrcplc.co.uk for the complete WRc/WAA manual.

2. All CCTV inspection reports shall be prepared by the competent person registered as the staff of the registered contractor. The CCTV reports shall follow the requirements listed below.

   Note: CCTV report/submissions that do not comply with the requirements will be rejected.

Preparation before CCTV Inspection

3. QP/contractor shall submit Form B to PUB to obtain the permission before entering any public sewer to carry out any works, inspection or CCTV sewer inspection. Failure to obtain permission from PUB is a violation of the Sewerage and Drainage Act. Offenders are liable for enforcement actions. Form B is an online form accessible at PUB Website

   (https://bpu.pub.gov.sg/Forms/EForms/Instruction?form=FormB)

4. CCTV contractors shall obtain permission to enter manholes in private properties. PUB may assist to issue letter of request if necessary. PUB may also instruct the CCTV contractor to carry out CCTV from an alternative manhole.

5. Pipelines/manholes/inspection chambers shall be hydraulically cleaned before inspection. This is to enable existing defects to be clearly recorded on video. CCTV contractor shall re-clean and re-inspect the sewer or manhole if the recorded view is obstructed or not clear.

6. All cleaning of public sewer shall be carried out by qualified operators certified in Sewer and Manhole Cleaning for Operator and Supervisor course (by SgSTT) or Operate a High Pressure Water Jetting System to Clean Pipelines and Appurtenances (WSQ). If sewer inspection cannot be carried out due to surcharge flow condition even after flushing/hydraulic cleaning, report the sewer to PUB WRN Ops Centre at 62894013.

7. CCTV contractors shall use supporting methods such as soap/dye test to verify existing drain line connection during the pre-con and/or post con CCTV works to confirm point of connection.

CCTV Recording

8. All CCTV recording shall be carried out using full feature pan, tilt, and zoom (PTZ) 5 camera. For sewers larger than 450mm diameter, the zoom feature shall be used to allow clear interpretation of all defects and its severity. Push Rod cameras may be used only in special cases when approved by PUB.

9. CCTV recording shall be done from manhole-to-manhole. In CCTV recording for single landed housing development, CCTV may commence from the entering manhole and end at the boundary.

Grading of the internal condition of the pipe

For structural grading, the worst defect along the individual sewer length is used to give a single condition grade for that particular sewer length, i.e. the grade for the sewer length is based on the highest internal condition score along the sewer length.

For service grading, the pipe length is assigned one of five service condition grades according to either where the peak score or the mean score gives the highest grade.

The MSCC observation codes are divided into four classes:

• Structural – codes that describe the physical condition of the pipe fabric.

• Service – codes that describe deficiencies in the hydraulic performance of the pipe.

• Construction – codes that illustrate the constructions assets of the sewer.

• Miscellaneous – other codes that do not fit into any of the 3 previous classes.

Only structural and service codes are scored, and not all are scored in each class.

Service codes are universal and can be used across all pipe material types. Some structural codes may only be used for brick/masonry conduits, and similarly for piped assets.

Any code containing a ‘J’ is deemed to be ‘at a joint’. This indicates that the observation is at a joint by definition, or it is within 200mm either side of the joint. The ‘J’ modifier is optional on many codes.

Any code description containing the word ‘other’ requires a mandatory comment against the code entry.

Only companies under PUB’s existing list of “Registered CCTV Contractors” will be allocated a company user account and company profile. Please refer to www.pub.gov.sg for more details on registration of CCTV Contractors.

Here are steps to view your company profile, as well as the users associated to the company.

Step 1: Login to the system with your id/password.

Step 2: At the Contractor Company Dashboard, click on “My Company” link.

Step 3: At the Company Profile page, you will see the Profile details and the users associated with your company.

There is a common tool used across the system to list information in a grid. This section describes the functions and capabilities provided with this grid which can be used in the system whenever there is list/grid required.

You can change the number of entries (results) to be listed per page. The default is 10 per page and the options are:

• 10

• 25

• 50

• 100

Depending on the number of items that are listed in the grid (# of entries per page, or filter conditions), the grid will be paginated according to the maximum number of items per page accordingly.

You may use the following options/buttons to navigate through the pages in the grid:

• Left Arrow: To navigate to previous page.

• Right Arrow: To navigate to next page.

• Page Number (First Page): The first number is always the first page. Click on it to jump to the first page.

• Page Number (Last Page): The last number on the right is always the last page. Click on it to jump to the last page.

• Page Number (In Between): Click on any of the page numbers in between to jump to those pages.

This section describes the functions to apply filters to the grid.

Enter any text here to filter the results across all columns.

The grid (result) will react accordingly when you enter your filter text in the universal filter.

For more granular filtering, you may apply filters under each column. You can use the column filters in combination (different columns).

The grid (result) will react accordingly when you enter your filter in the column filters.

You can reset the listing by clearing all the filters.

All results in the grid can be sorted by clicking on each column header. Change the sort order by clicking on the column header again.

Below are the icons to differentiate between ascending or descending sort order.

All the information in the grid can be exported to excel. The export will be based on all information listed in the grid (according to the filter conditions).

After filtering the information according to your needs, you may export the information to excel by clicking on the “Excel” button.
