Collection System Maintenance

DownStream Services, Inc. (DSI) provides Operation and Maintenance Programs (O&M) to municipal and industrial agencies tailored to meet specific pipeline maintenance requirements. DSI has the technical and operational expertise to develop a program, manage information, and proactively schedule preventative maintenance for sanitary sewer systems.  

DownStream develops O&M Programs in support of and as an integral part of an overall Sewer System Management Plan (SSMP). DSI employees hold Collection System Maintenance Grades 1 through 4 and maintain the highest levels of safety training in the industry with 12 scheduled refresher courses per year and a minimum of sixty hours of professional training per employee. These programs are designed to be cost efficient and can be developed around industry standard software (access database) or any of the proprietary software’s on the market.

O&M Programs combine Global Positioning System (GPS), Geospatial Information Systems (GIS), and Sewer Inspection databases into a comprehensive visual interface that can be easily managed and accessed. Various tasks can be interchangeable and seamlessly completed by DSI staff, agency staff, or a combination of both. Examples of these tasks would be:

Field Tasks:

	Inventory mapping of assets via GPS locating^
	CCTV inspection to determine pipe condition and assign priority ratings to defects.
	Pipe cleaning and documentation of the type and amount of debris in each segment
	Manhole inspections
	Infiltration and inflow study
	Flow Monitoring

Office Tasks:

	GPS data differential corrections^
	GPS data conversion for GIS use
	GIS map creation
	Input data from CCTV and cleaning operations and database creation

	Merge database into O&M Program
	Database customization
	Interview your operators and managers to collect information they have on "problem lines"
	Review previous CCTV inspection information

^GPS data is collected within sub meter tolerances, but is not certified by a licensed land surveyor.

Developing a cost efficient O&M Program will allow you to focus efforts where they are needed most. By applying historical data, DownStream can create a baseline that will provide the following:

	Establish cleaning schedules based on objective standards from field inspections
	Manage system assets proactively instead of reactively
	Reduce cleaning efforts in segments that are hydraulically self-cleaning
	Optimize crews productivity
	Schedule crews weeks in advance based on maintenance priorities
	Print maps with asset information to help field crews identify and locate assets
