Resources Required to Implement the Program IX. Program for Continuing Program Improvement X. Identify Responsible Person or Organizational Unit XI. System Program Audit Project Background SCWD provides water and sewer service to approximately 40,000 residents in the communities of Dana Point, South Laguna Beach, north coastal San Clemente, and a portion of San Juan Capistrano. Its wastewater collection system collects and conveys four (4) million gallons a day (mgd) of wastewater from residences and businesses to two treatment plants via a 136-mile system of pipelines, which includes 14 lift stations and 3 miles of force mains. SCWD is permitted as a satellite wastewater collection agency to collect and convey wastewater for treatment to the South Orange County Wastewater Authority under a National Pollution Discharge Elimination Permit issued by the San Diego Regional Water Quality Control Board (RWQCB). The RWQCB is authorized to enforce the Federal Clean Water Act (CWA) in south Orange County and the western portions of San Diego and Riverside counties.

5 Revised Short-Term and Long-Term Sewer Pipe Inspection and Condition Assessment Program 2 EPA issued a Finding of Violation and Order for Compliance (Order) on September 30, The Order requires that the SCWD take aggressive measures to reduce the number of sewage spills from its collection system. The Order establishes five plans that must be prepared by SCWD. On February 10, 2004, SCWD submitted an Implementation Plan for Compliance with EPA Order CWA during a meeting with EPA in San Francisco. The document requested that EPA accept the revised implementation plan and that the timelines contained in the EPA Order be modified accordingly. On February 28, 2004, EPA notified SCWD that the revised deadlines contained in the Implementation Plan for Compliance with EPA Order CWA were acceptable. HOW THIS DOCUMENT IS ORGANIZED A summary of SCWD s programs is presented in the following sections, which are organized in accordance with the 11 components enumerated above. These programs, processes and procedures are described in detail in a variety of documents prepared by SCWD. It is not SCWD s intent, nor is it practical to include detailed documents containing thousands of pages in this summary. Instead, for each component, the purpose, goals, and documentation are referred to and the actual reference documents are presented as electronic links. In the reference documents section, document titles that appear as blue text and are underlined have been electronically attached to this summary document. The attached documents can be assessed by using the control key (Ctrl) and clicking on the title. REFERENCE DOCUMENTS (LINKS TO ELECTRONIC DOCUMENTS) EPA Administrative Order.pdf Implementation Plan for Compliance.pdf Strategic Plan.pdf PURPOSE OF THE PROGRAM The purpose of the sewer pipe inspection and condition assessment program is to ensure that the gravity lines within the wastewater collection system gravity lines are maintained in a manner that achieves SCWD s established customer service, regulatory compliance, asset management and work management strategic goals.

6 Revised Short-Term and Long-Term Sewer Pipe Inspection and Condition Assessment Program 3 GOALS ESTABLISHED FOR THE PROGRAM The overall goals of the sewer pipe inspection and condition assessment programs are as follows: Protect public health and the environment through prevention of sanitary sewer overflows and by meeting water quality standards; Periodically inspect below grade sanitary collection system assets following hot spot cleaning and post construction requirements; Evaluate structural defects in accordance with a set defect criteria; and Add defective assets immediately to the sewer rehabilitation funding mechanism for necessary repairs. REVISED SHORT-TERM AND LONG-TERM CURRENT PRACTICES FOR THE SEWER PIPE INSPECTION AND CONDITION ASSESSMENT PROGRAM Short-Term Plan for Periodic Inspection and Assessment of Sewers and Maintenance Holes SCWD conducts periodic inspection and assessment of the sewers and maintenance holes (MHs) as part of its system-wide preventive maintenance program. Daily logs and monthly logs are completed identifying the linear footage of hot spots cleaned, pipelines CCTV d and the number of manholes inspected. Long-Term Plan for Periodic Inspection and Assessment of Sewers and Maintenance Holes As discussed in the Long Term Plan for Pipe Condition and Assessment, SCWD will establish an information-based cleaning program that will include periodic inspection and assessment of the sewers and MHs. Long-Term Strategy: Implement condition rating system as identified in the Pipe Condition and Assessment Program. Short-Term Plan for Follow-up Procedures to Blockages All personnel are required to have a copy of the Sanitary Sewer Overflow Prevention Plan (SSOPP) and Sanitary Sewer Overflow Response Plan (SSORP) in the SCWD vehicle at all times. All sanitary personnel participate in periodic SSOPP/SSORP training and review sessions, and personnel are required to sign and initial the document to acknowledge their understanding of the

7 Revised Short-Term and Long-Term Sewer Pipe Inspection and Condition Assessment Program 4 SSOPP/SSORP. The SSOPP/SSORP are living documents, which are referenced and crosschecked for completeness, reviewed on a regular basis and updated as needed. The documents are also reviewed after each sanitary sewer overflow (SSO) event. The SSOPP/SSORP was last updated in June 2004, at which time copies were provided to the San Diego Regional Water Quality Control Board (RWQCB) (Region IX) in compliance with Regional Board Order Review and revisions to the SSOPP/ SSORP will be made as needed; however, formal review of the documents will be completed on a bi-annual basis. The typical sequence of activities to be followed by maintenance crews when responding to blockages is to evaluate, remediate, mitigate and report (see Emergency Response to Sewer Spill). In addition, CCTV is frequently used in collection system lines to assist in establishing the cause of failure and determining the required repair. The repair occurs the same day as the overflow (unless there are extenuating circumstances). All overflow incidents are reported to the Regional Board (Region IX) regulatory agency as described in the SSOPP/SSORP. If a spill is estimated to be greater than 1000-gallons or the SSO reaches Waters of the U.S. the following SSO report information and documentation are provide to the RWQCB. 1. Final SSO Report (as established by the RWQCB) 2. Preliminary SSO Report 3. SSO Debriefing Team Meeting Memorandum 4. Photographs of SSO 5. Sewer Line Maintenance History 6. Location Map 7. Orange county Department of Health Services SSO Notifications 8. Ocean Water Test Sample Results Follow up procedures regarding sewer lateral are investigated by SCWD. According to SCWD s Ordinance No. 197, Article 8, Section The lateral service connection shall be maintained in good condition free of grease, roots, and other obstructions in accordance with District Ordinance 190; and the maintenance of the lateral is the responsibility of the owner of the property from the structure to the mainline in the street owned by the District, including the saddle or actual point of connection to the mainline. SCWD utilizes CCTV to inspect the sewer main upstream and downstream of the sewer lateral connection to identify whether SCWD s main pipeline is or is not responsible for problems regarding the private sewer lateral. Response procedures for SSOs from private sewer laterals are to evaluate, remediate, mitigate, and report. The procedures are the same for SSOs caused by private sewer laterals as they are for the SCWD collection system.

8 Revised Short-Term and Long-Term Sewer Pipe Inspection and Condition Assessment Program 5 Long-Term Plan for Follow-up Procedures to Blockages SCWD will continue to implement the follow-up procedures identified in the short-term plan or as required by the SSORP and the regulatory agencies. As part of the long-term plan, information regarding a spill and location of the spill will be incorporated into the future CMMS program. This will assist with creating specific work orders to provide the required 0preventative maintenance at the specific pipe segments where the spill occurred. Long-Term Strategy: Continue existing methods for Follow-up Procedures to Blockage Short-Term Plan for Pipe Condition and Assessment SCWD completed a video survey in April 2004 of all gravity sewer lines in the Capistrano Beach service area, Dana Point service area, and the South Coast service area. As a result of the video survey, a list of necessary repairs were developed and separated into priority one, two and three projects, with priority one being the most urgent. The ranking of repairs was developed based on review and analysis of the video survey and is organized by sewer run (from manhole to manhole). The video survey uses a defect rating system to assist in the analysis. The rating system includes a severity index that assigns numerical values to every defect that occurs in sewer lines according to the level of damage, obstruction or infiltration to the pipe. Defect scores range from 0 to 1000; with 0 meaning no damage and 1000 meaning pipe section has collapsed. After analyzing the defects in a particular sewer run, staff classifies the run into one of the three levels of urgency as mentioned above. The criteria for each priority classification are as follows. Priority #1: Repairs that need to be completed within the next one to six months. 1. Line is broken, missing sections, severed, and/or ready to collapse. Lines in this priority usually contain defects that score over 400 on the severity index. Typical defects and scores include: Broken Pipe (500), Hole in Pipe (500), Separated Joint, Severe (475), and Offset Joint, Severe (425). 2. Lines whose level of damage falls on the borderline between priority 1 and 2 remain priority 1 if their flows are greater than half full under peak flow conditions. Priority #2: Repairs that need to be completed within the next 6 to 12 months. 1. Line is damaged but still functioning and contains cracks and moderate offsets and separations. Lines in this priority usually contain defects that score between 350 and 400 on the severity index. Typical defects and scores include: Multiple Cracks at Joint (360); Separated Joint, Medium (350); and Offset Joint, Medium (350).

9 Revised Short-Term and Long-Term Sewer Pipe Inspection and Condition Assessment Program 6 2. Lines whose level of damage falls on the borderline between priority 1 and 2 remain priority 2 if their flows are less than half full under peak flow conditions. Priority #3: Repairs that need to be completed within the next 12 to24 months. 1. Line has smaller cracks/minor separations/offsets/differing materials, and minor to moderate defects that will continue to deteriorate. This line should be monitored on a regular basis. Lines in this priority usually contain defects that score below 350. Typical defects and scores include: Circumferential Crack (350), Longitudinal Crack (350), Offset Joint, Slight (250), and Sags (233). SCWD has completed all Priority 1 repairs for the entire system. Priority 2 repairs have been completed for Capo Beach and Dana Point service areas. Priority 3 repairs will begin in September/ October for the Capo Beach service area. SCWD is currently working on completing the Priority 3 repairs identified. SCWD s current strategy for identifying repairs is to identify additional repairs through in-house regular CCTV inspections, annual cleaning, and on-going inspection of current hot spot locations. Priority repairs or pipe segments requiring repair or rehabilitation are placed on an Other Repair list. The pipe segments included on the Other Repair list are repaired, replaced, or rehabilitated within 6 months or sooner if the pipe presents a more critical danger of collapse. Long-Term Plan for Pipe Condition and Assessment SCWD s strategy is to establish a condition rating for all pipe segments throughout the system. SCWD s operation staff will be trained to assess each televised pipe segment using the newly developed ABCD rating system, described below. Inspection Frequency Cleaning Rating Condition (CCTV) Frequency A Good Every 5 years Every 3 years B Fair Every 2 years Every 2 years C Poor Annually Annually/ Biannual/ Quarterly D Failed Fix Immediately The goal is to reduce the potential for structural failure and to reduce the potential for blockages caused by failed pipe material falling in the flow path. The rating system will become an integral part of the development of maintenance schedules and the need for repair, replacements and rehabilitation. The rating system will incorporate the current Priority 1, 2, and 3 ranking procedure with its newly developed A, B, C, D system. Those pipe segments determined by SCWD to be ranked as C and is a known hot spot location will remain on a quarterly cleaning cycle.

10 Revised Short-Term and Long-Term Sewer Pipe Inspection and Condition Assessment Program 7 Schedule for Completing Long-Term Strategy: SCWD anticipates program training and implementation of CCTV operations staff to begin in Fiscal Year 2006/2007. Short-Term Plan for Inspection Methods Used, Including Direct Visual Inspection and CCTV Inspection SCWD budgeted $750,000 for CCTV inspection of the entire 136 miles of gravity sewer pipeline. The video inspections of the entire collection system are complete. This video inspection provides the baseline assessment of SCWD s collection system. SCWD owns and maintains its own 2001 Pearpoint video inspection equipment. This video equipment is used regularly to inspect repaired pipe segments, hot spot areas and new or potential trouble spots, to verify success of repairs, condition of pipelines and need for repairs. Generally, all repaired segments and hot spot areas are video inspected for verification prior to removal from quarterly tracking lists and placed on annual maintenance. System-wide CCTV for each of the service areas was contracted to an outside firm and was completed for all service areas in April SCWD will continue to use CCTV randomly and on an as-needed basis to inspect potential problem areas, verify pipe conditions, provide random quality control checks, and provide pipe assessments. As of April 2005, SCWD has inspected approximately 10% of the collection system (annual basis). Long-Term Plan for Inspection Methods Used, Including Direct Visual Inspection and CCTV Inspection SCWD will continue using the current video inspection method (CCTV) to update the assessment of the SCWD collection system, per the Long-Term Plan for Pipe Condition and Assessment. SCWD anticipates that approximately 15% to 20% of the collection system will be televised each year by in-house staff. SCWD plans to complete a CCTV reassessment goal for the collection system over a period of 5 to 6 years. SCWD plans to utilize the future CCTV video recording to assess pipe condition and incorporate a modified cleaning schedule based on the condition and rating of each pipe segment. The videobased assessment data will populate the future Computer Maintenance Management System (CMMS) and the Geographic Information System (GIS). This enables the use of an informationbased system for scheduling inspections. CCTV is an essential element to of the collection system assessment program. To maintain this capability, SCWD will replace and maintain CCTV equipment as required.

11 Revised Short-Term and Long-Term Sewer Pipe Inspection and Condition Assessment Program 8 Schedule for Completing Long-Term Strategies: In-house training and implementation of CCTV of approximately 15% to 20% of the collection system with new rating system to begin in Fiscal Year 2006/2007. Short-Term Plan for Identifying the Inspection Schedule Including an Estimation of How Many Maintenance Holes and Miles of Pipe to be Inspected Each Year for the Next 5 Years The SCWD service area has approximately 136 miles of pipeline and 3,408 MHs. All maintenance holes are visually inspected during the annual system-wide cleaning program. The need for additional inspection and maintenance will be an information-based program established with the results of the CCTV inspection, grease management results, root management identification, and additional on-going annual maintenance and cleaning of the collection system. Long-Term Plan for Identifying the Inspection Schedule Including an Estimation of How Many Maintenance Holes and Miles of Pipe to be Inspected Each Year for the Next 5 Years The goal is to develop the GIS and a CMMS that becomes the basis of an asset management program. These tools would provide a method to estimate the quantity of maintenance holes and pipe lengths that must be inspected annually for the next 5-years. Geographic Information System (GIS) SCWD plans to phase the implementation of a comprehensive GIS system for its water, recycled water, and sewer systems. Several components are currently being implemented, including: Acquisition of the County of Orange s assessor parcel maps Conversion of the data for all sewer, water and recycled water assets, and performing the following tasks: i. Designing and developing databases for capturing key attributes of these systems; ii. iii. iv. Digitizing all water, recycled water, and sewer assets; Scanning all the SCWD As-Builts and linking them to the digitized infrastructure for easy retrieval and reference; and Developing a GIS application interface with overall management, query and reporting capabilities. Documentation of known easements with cross-reference information Installation and training

12 Revised Short-Term and Long-Term Sewer Pipe Inspection and Condition Assessment Program 9 One of the key benefits of this program will be to help with the ongoing Operations & Maintenance (O&M) activities of these facilities. Implementing the GIS assists in managing the system s human and material resources as effectively as possible while achieving regulatory compliance and delivering a high level of service to customers. Other benefits include: Ensuring facilities and equipment availability; Maintaining equipment and facilities reliability; and Maintaining the value of the investment. SCWD has currently completed the GIS of the Capistrano Beach Service Area. Completion of the GIS for the Dana Point and South Coast Service areas is expected to be completed by December Computer Maintenance Service System (CMMS) SCWD recently had a kick-off meeting for the development of the CMMS. The RFP covers such areas as the selection and management of a CMMS vendor; development of the system implementation plan, provision of technical resources; assessment of current maintenance practices; establishment of industry best maintenance practices in association with SCWD staff and overall management and oversight of the CMMS implementation program from selection through to final delivery to SCWD. The primary function of the CMMS will be to enable SCWD to efficiently and cost-effectively manage system assets, equipment and facilities by minimizing long-term costs of owning, operating, maintaining and replacing SCWD assets while ensuring reliable and uninterrupted service. The CMMS will facilitate optimization of time/ labor resources required to operate, maintain and manage the infrastructure and facilities. Information provided by the CMMS are essential for assetbased maintenance activities and for supporting long-term business decisions. Implementation of the CMMS is anticipated to begin June Schedule for Completing Long-Term Strategies: Completion of GIS for the sewer system of Dana Point and South Coast Service areas is anticipated for December Implementation of CMMS is anticipated to begin June Evaluation of the implementation of asset management into the CMMS will be considered by January Short-Term System for Timely Evaluation of Inspection Results SCWD began CCTV of the entire collection system in October CCTV of the entire system was completed in April Initial results of the ongoing CCTV effort for the Capistrano Beach service area were received October SCWD initiated an immediate evaluation of CCTV results

13 Revised Short-Term and Long-Term Sewer Pipe Inspection and Condition Assessment Program 10 by dedicating a full-time employee (see Identify Responsible Person or Organization Unit) and retained additional consulting assistance to complete the evaluation of the video survey. The results from all service areas were completed in April 2004 and it is anticipated that the complete evaluation will be completed by July Long-Term System for Timely Evaluation of Inspection Results SCWD will continue to dedicate a full-time employee to evaluate the internal video survey results. In addition, all CCTV crew members will be trained to evaluate each pipe segment, using the new method of Pipe Condition and Assessment described above. In addition, SCWD will utilize outside services to review and verify video survey results, as required. DOCUMENTATION SCWD conducts routine CCTV inspection of its gravity conveyance system following hot spot cleaning inspections, repairs, and replacements of pipe segments. CCTV inspection provides continuous inspection of up to 1,000 feet of pipe. CCTV is well suited for determining joint conditions, root intrusion, sources of infiltration, and locating structural deficiencies. Inspection documentation is made on inspection log forms, which are reviewed by the Sanitary Collection Supervisor or Senior O&M personnel and are supplemented with videotape. The TV Inspection Form provides a detailed logging of defects encountered during the inspection. Maintenance holes (MHs) inspections are completed during the annual sewer system cleaning. MH inspections include visual inspections of the surface, rungs, structural defects, indication of roots, insects, debris buildup, cover, and odor. Inspections of MHs are documented on the Manhole Inspection Form. In addition, SCWD has established a priority ranking of repairs (discussed in Current Practices). Based on the ranking, the rehabilitation and replacement have been prioritized for completion within the next 1 to 24 months. Lists of Priorities 1, 2, and 3 and Other Repairs have been developed for all service areas within South Coast Water District. Each list identifies the physical location, the CD number, upstream and downstream manholes, comments, length of repair, action taken and date completed. A summary of totals of Priority Repairs has also been developed.

SCWD is responsible for receiving notification from the public of sanitary sewer overflows from the collection system, and for dispatching the on-call duty personnel. When a call is received, the responding crew completes the Sanitary Department Spill Procedures Check List. During regular business hours (7:30 AM-5:00 PM), the SCWD Collection System Department is able to respond within 30 minutes of the initial call. After regular business hours, the SCWD Collection System Department responds within 45 minutes. Once the collection system operations and maintenance crew is dispatched, the crews immediately check the manhole downstream of the location to verify whether the spill is associated with the main sewer pipeline or the service lateral. In either instance, the main sewer pipeline is hydro flushed to clear any blockages. If it is determined that the spill is being caused by a service lateral, the water service to the service lateral location is immediately turned off to prevent further overflow. If an overflow has occurred, personnel initiate spill containment and control, take necessary photographs, and complete the necessary spill procedures and reporting identified in the SSORP.

15 Revised Short-Term and Long-Term Sewer Pipe Inspection and Condition Assessment Program 12 REFERENCE DOCUMENTS (LINKS TO ELECTRONIC DOCUMENTS) Emergency Spill Procedure Check List.pdf RWQCB SSO Report Form.pdf SOP - Emergency Response.pdf SSOPP AND SSORP.pdf STAFF TRAINING REQUIRED TO ENSURE PROPER IMPLEMENTATION The SCWD Sanitary Department ensures that operations and maintenance staff have the skills, knowledge and abilities required to correctly undertake the work that they are assigned. Goals established in the Strategic Plan are to: Promote an efficient and productive workforce, and Attract and retain a skilled workforce. Supervisors conduct weekly safety meetings with SCWD personnel. In addition, annual training is provided to the collection system staff. Personnel are certified through outside organizations and seminars in varying fields, which include: CWEA Collection System Certification CPR and First Aid Training Confined Space Entry Certification Fall Protection Training Heavy Equipment Training Sexual Harassment Training Defensive Driving Seminar Traffic Control and Flagger Seminar (every 2 years) Back Safe Program (every 2 years) Sanitary Operations personnel attend several training sessions for the Pearpoint equipment, which include: Five-day training, operations and safety seminar for the CCTV camera; One-day training with the Flexi-data computer program for the CCTV camera; and Five-day training and certification program on the camera and program.

16 Revised Short-Term and Long-Term Sewer Pipe Inspection and Condition Assessment Program 13 Two operations personnel have been sent through the NASSCO Pipeline Assessment Certification Program. Additionally, the collection system personnel are required to carry the SSOPP and SSORP in the District vehicle. Refresher training on both the SSOPP and the SSORP is required and conducted periodically or whenever the documents are modified or updated. REFERENCE DOCUMENTS (LINKS TO ELECTRONIC DOCUMENTS) NASSCO Pipeline Assessment Program.pdf SSOPP AND SSORP.pdf PROGRAM QUALITY AND QUANTITY PERFORMANCE MEASURES NASSCO Certified personnel complete in-house condition assessments. Prioritizations of the defective pipe segments are determined by the specified scoring of defects (see Pipe Condition and Assessment). SCWD calibrates the remote-reading footage counter every six months to ensure measured distances and to minimize percent error. CCTV inspections conducted post-installation of spot repairs and pipe segments by outside contractors and in-house personnel are completed to determine if the installation was completed per contract documents and all-laterals are re-established, as required. Pipe defects identified are brought to a supervisor s attention at the end of the workday. Additionally, joint testing is used to test the integrity (tightness or leakage) of individual pipe joints. Testing is performed by applying a pre-determined pressure to the entire circumference of chosen pipe joints. A joint passes the test if it can hold the required pressure, otherwise the joint fails the test and the joint is sealed with grout. RESOURCES REQUIRED TO IMPLEMENT THE PROGRAM The complete inspection of the wastewater collection system was contracted through an outside contractor. One contract person and one SCWD staff member are completing analysis and prioritization of the video inspection. SCWD owns and operates one truck that contains Pearpoint camera, service lateral camera attachment, and all associated computer program equipment. Typically, the truck requires two staff members to operate. Three people are required for heavy traffic areas. The truck is fully equipped with required traffic control equipment, 1000-feet of cable, camera, VHS recording equipment,

17 Revised Short-Term and Long-Term Sewer Pipe Inspection and Condition Assessment Program 14 television, and program equipment. The TV inspection form is an electronic form that is complete for each line segment following the completion of CCTV. The form is generated with the defects identified during the inspection. The CCTV truck has been sufficient in completing the quarterly hot spot inspections, contractor pipeline replacement projects, on-going collection system reviews and as-needed emergency inspections established by SCWD. PROGRAM FOR CONTINUING PROGRAM IMPROVEMENT SCWD includes in the annual budget and sends personnel to CMOM conferences and other collection system educational conferences. New technology or methods obtained from the conferences are discussed with senior staff to determine whether the information obtained would be beneficial to the existing programs. All modifications are discussed with all personnel at weekly staff meetings. Pearpoint sends periodic updates for existing camera equipment. Senior personnel review all product updates to determine whether updates should be implemented into SCWD s programs. SCWD reviews the success and effectiveness of the programs and redoes the SOPs as necessary and this is documented in the notes of the meetings. IDENTIFY RESPONSIBLE PERSON OR ORGANIZATION UNIT The Sanitary Collection Department consists of one supervisor, three Senior Operation and Maintenance (O&M) personnel, one Mechanic, two O&M II, and six O&M I, as shown on the organization chart. Crews are assigned to specific work duties, including lift station O & M, pipeline cleaning and pipeline video activity.

18 Revised Short-Term and Long-Term Sewer Pipe Inspection and Condition Assessment Program 15 In addition, Tom Richards (Special Projects) has been dedicated to the CCTV Assessment of the SCWD Collection System. Job descriptions for all personnel in the Sanitary Collection Department have been identified in the SSOPP and SSORP. Each description includes: Definition, Distinguishing Characteristics, Supervision Received and Exercised, Examples of Duties, Qualifications, and Experience and Training Guidelines.

19 Revised Short-Term and Long-Term Sewer Pipe Inspection and Condition Assessment Program 16 SYSTEM PROGRAM AUDIT SCWD plans to audit the Sewer Pipe Inspection and Condition Assessment Programs on a two-year basis. The audits will be a formalized review process of the purpose, goals, procedures, documentation, and required training presented in this summary. The audit will determine the effectiveness of the existing programs and the need to improve or update as required by existing equipment and the advancement of technology. SCWD s long-term strategy is to develop a condition rating for all pipe segments throughout the system. The goal of the rating system is to identify the need for future sewer system pipe inspections and condition assessments.
