Veolia has successfully implemented customized underground asset management (UGAM) programs for communities across North America.
WOONSOCKET, RHODE ISLAND
In 2009, the City of Woonsocket expanded the scope of its partnership, awarding Veolia a second contract for the operation and maintenance (O&M) and underground asset management (UGAM) of Woonsocket's 120 mile collection system for the next 10 years. As with the treatment facility agreement, Veolia Water provided a $1 million concession fee. Under the contract, Veolia is responsible for pipe cleaning and defect condition assessment, debris removal MACP inspection for 350 manholes, management for a three-person crew, all capacity, management, operation and maintenance (CMOM reporting, and 24-7 on-call emergency response.
Using InfoNET asset management software, the UGAM team was able to pinpoint the system's trouble spots and reduce the number of locations in need of routine maintenance. This allowed Veolia to concentrate field technicians on an accelerated preventive maintenance and condition assessment program, which resulted in the following in the first two years of the contract:
- Total sewer system overflows (SSOs) were reduced by more than 48%.
- Customer complaint calls were reduced by 71%.
- Veolia removed 275 tons of debris from the collection system through the flushing-vactor program.
- The team eliminated 80,000 GPD of infiltration sources identified through the CCTV condition assessment program and the in-house epoxy point repair system - more than 29 million gallons per year.
In 2006, the City of Taunton expanded Veolia’s scope of work to include management of the collection system. Through a comprehensive plan that employs advanced methodology and technology to assess system condition and establish criticality, 90 miles have been televised, 200 miles have been cleaned and more than 989 tons of debris have been removed as of 2011, and the hydraulic capacity of the 9-MGD wastewater treatment plant has been increased by more than 40% through I/I reduction.
Veolia’s on-site management team also works with the City on the following:
- Establish a fats, oils, and grease (FOG) program with the Board of Health to locate grease blockages and identify sources of non-compliance.
- Capacity assessment and site-plan reviews for sewer tie-ins and acceptance programs for new developments and transfer from septic.
- Managing all emergency repairs and State Revolving Fund (SRF) improvement projects.
- With the DEP and DPW, Veolia investigates to remove illicit sanitary connections within the stormwater system.
- Managing the City's shared lateral elimination and separation program.
- Through GIS data improvement, Veolia discovered 61 miles of sewer
- Veolia is on track to meet the goal of eliminating the sole permitted CSO upstream of the main lift station by 2014
FALL RIVER, MASSACHUSETTS
After the City of Fall River was fined by the EPA for not meeting permit compliance for their municipal separate storm sewer system program (MS4), the City tasked Veolia in March 2011 with creating a GIS map of the 179-mile sewer system and conducting outfall screening. There are approximately 1400 catch basins, 900 manholes and 35 miles of pipe in the stormwater GIS which have been mapped through field surveys and digitizing of record plans. The scope of the program will continue to expand throughout 2012. Currently, Veolia's on-site Stormwater Manager works with the city on the following:
- Develop and implement a public outreach program, including a new stormwater website for residents
- Complete water quality sampling and prepare the 2011 annual report for EPA.
- Distribute the Stormwater Training Video to city departments and track who has seen the video
- Begin identifying trouble areas in the system using the GIS map
NEW LONDON, CONNECTICUT
For the City of New London, Veolia created an integrated UGAM program to meet capacity, management, operation and maintenance (CMOM) program requirements for the City's 122-mile underground collection system. New London had a strong GIS platform in place, and Veolia linked together CMMS, GIS and underground asset software to provide a fully-integrated IT system that offers significant value. The IT integration will improve the utilization of information databases to bring better decisions to the operation and management of the utility system.Veolia uses the information to develop efficient capital plans, provide better customer service and deliver a higher level of service. The ongoing program has delivered significant results to the client, including:
- 56 miles of CS have been cleaned and 42 miles have been televised as of 2011
- Unaccounted-for water losses from the DS have been reduced by 11%, saving 365 million gallons a year.
- Maintenance activities, such as sewer main cleaning, video line inspection, smoke testing, flow monitoring and manhole condition assessment, are now recorded on the underground asset software, allowing the City of New London to build institutional knowledge
Since 2006, Veolia has managed the 93-mile underground collection system and 49-mile storm drainage pipelines for Fort Knox, and has developed a customized UGAM Program based on CMOM guidelines. Veolia conducted a system condition assessment to establish a protocol for tackling the necessary repairs and improvements. We developed a criticality matrix that classified the system's most critical elements to assist staff in developing a hierarchy and timeline for ranking capital projects and repairs. The ongoing project has delivered savings and significant results to the client.
- Within the first year alone, Veolia identified more than 750,000 additional linear feet (lf) of line over 15,000 other below-grade assets (manholes, culverts, catch basins, etc.) that have been mapped into the GIS.
- Through means such as smoke testing, CCTV and flow monitoring, sources of I/I were identified, providing the foundation for pipe-lining projects.
- A computerized maintenance management system (CMMS) is tied to the wastewater treatment facility, providing the capability to track the maintenance activities and work orders associated with the underground system elements.
- In the initial two years of the contract, Veolia Water completed a $2 million capital program to upgrade and repair the collection system. More than 8,500 feet of sanitary and storm sewers were repaired and 300,000 lf of lines were evaluated through smoke testing or CCTV inspection.
- The number of SSOs per year have been cut in half since Veolia implemented the program
BUFFALO, NEW YORK
In July of 2010 the City of Buffalo and Veolia began a 10-year partnership for the operation and maintenance of its water supply system. Key to this partnership is developing and implementing a customized UGAM program for a system that includes 785 miles of water transmission mains, 22,120 valves, and 7,800 fire hydrants. At the core of Veolia's strategy are anintegrated IT Solution and GIS Data Integration at the water system operational level. This will lead to a fully automated maintenance management system that optimizes operations and provides an immediate return on investment for the Water Authority. The partnership continues to exceed expectations and deliver value:
- InfoNet will also be implemented on a mobile basis to provide field crews with direct access to all asset-related data during the actual performance of maintenance or repair efforts.
- Veolia has also initiated a water distribution system condition assessment using our proprietary validated mathematical statistical modeling tools.
- Meter reading routes have been optimized and refined to ensure that actual (not estimated) meter reads are being collected
- Veolia has proposed several joint-venture pilot studies with the Water Authority, including waterline physical condition assessment and a field test of Veolia-vetted AMR and advanced metering initiatives.
The 148-mile collection system includes 62 lift stations and nearly 3,000 manholes. Portions of the lines were constructed in the mid-1950s. Veolia implemented a pipe-lining program to repair deteriorating collection system lines, initiated a PACP sewer inspection program, and reduced odor complaints through an aggressive pump station and line cleaning and flushing program, as well as a.system survey to locate problem areas and repair of the odor scrubber. In 30 months, Veolia's team has cleaned 84 miles and CCTV'd 88 miles, and there were no SSO's in 2010.
Milwaukee has nearly 350 miles of complex underground conveyance systems for wastewater and stormwater. Veolia is implementing state-of-the art programs that verify the operational readiness of critical system components; improve remote monitoring to provide more complete feedback on real-time system performance, and maximize treatment efficiency. Veolia also provides various means for rate payers and other stakeholders to provide feedback on system performance and has implemented an educational outreach program for the public. Through implementation of the most modern methods of underground asset management, such as CMOM and ICOMMM, Veolia Water is improving the integrity, dependability and functionality of the District's conveyance and collection system.
