APRIL 2016 – ICE PIGGING

Consultants, City Engineers, and Public Works Managers are tasked with addressing various pipeline capacity and/or water quality issues on a regular basis.  These issues can be ongoing problems that require scheduled maintenance; or can be the result of an abrupt change in your pipeline operation that has you scrambling to deal with a major obstruction or quality concern.  From source to drain, our water and wastewater systems are full of pressurized pipes that require monitoring, maintenance, and repair from time to time.

 

A buzz-word term you may have heard lately is “Ice Pigging”.  Ice Pigging is a pipeline pigging process in which an ice slurry is pumped into a pipe and forced by pressure to remove sediment and built-up deposits leaving the pipe clear and obstruction free.  When it comes to many city water and wastewater systems, the reality of ice pigging is that it can be expensive with limited applications.

 

One recent study compared ice pigging to traditional pipeline swabbing of watermains.  The results showed that traditional swabbing was more effective and less costly than ice pigging.  SFE Global is your local pipeline pigging contractor with extensive experience in all applications:

 

  • Domestic and Raw Water Systems
  • Sanitary Sewer Force Mains
  • Sanitary Sewer Siphon Mains
  • Wastewater Treatment Plant Pipelines
  • Marine Intakes and Outfalls
  • Agriculture Irrigation Pipelines
  • Petroleum Products Pipelines
  • Mine Tailings Pipelines
  • Dedicated Fire Suppression Systems

 

 

 

Pigging and swabbing of pipelines, when performed by a company specializing in these specific services, is a cost-effective solution for improving capacity; reducing pumping costs; and improving water quality.

April 2015 – Pipeline Pigging Services

City Engineers and Public Works Staff have the relentless task of ensuring our underground pipelines are meeting the demands of public.  Whether it’s a domestic watermain or sewer forcemain, our underground pipelines need to efficiently carry water to the customers and wastewater to the treatment plants.

Sewer forcemains with capacity problems lead to overwhelmed lift station wet wells, poor pump performance, and ultimately combined sewer overflows or sanitary sewer overflows. (CSO/SSO)  Raw or domestic watermains with silt or scale buildup lead to water quality problems, higher than normal operating pressures, pipe breaks, and reduced firefighting capabilities.

 

 

 

 

 

 

 

SFE Global’s approach to pipeline pigging services starts with evaluating and understanding your current pipeline concerns.  Our team has the ability to perform system diagnostics prior to introducing pipe pigs into the system.  These services include:

  • Lift Station Drawdown Testing
  • Pressure and Flow Data Logging
  • C-Factor Testing
  • Safety and Hazard Assessments

 

 

 

 

Once an appropriate approach has been considered, SFE performs all pigging services with in-house crews, equipment, and materials.  Our team has collectively over 60-years’ experience in pigging services.  Typical pigging projects include:

  • Domestic and Raw Water Systems
  • Sanitary Sewer Force Mains
  • Sanitary Sewer Siphon Mains
  • Agriculture Irrigation Pipelines
  • Petroleum Products Pipelines
  • Mine Tailings Pipelines
  • Dedicated Fire Suppression Systems
  • Various Wastewater Treatment Plant Pipelines

Depending on your pipeline, you can expect one or more of the following results from pipeline pigging:

  • Increase pipe capacity
  • Decrease friction loss
  • Increase pump efficiency while reducing pumping costs
  • Improve water quality
  • Ensure pipelines are clear from all debris
  • Assess potential pipe deformation

November 2013 – Low Impact Development Performance Monitoring


Low-Impact Development (LID), a term used to describe a land planning and engineering design approach to managing stormwater runoff.  LID emphasizes conservation and use of on-site natural features to protect water quality along with reducing peak flow rates during various intensity rainfall events.

LID projects have become commonplace in our Cities, Counties, and Districts… but are they performing to the engineered specification?  Are they working at all?  Frequently used LID practices include:

  • Rain Gardens
  • Green Roofs
  • Pervious Pavers
  • Bio-swales
  • On-site Infiltration Pits
  • Commercially manufactured stormwater management devices

 

SFE Global has extensive experience in monitoring the performance of these LID projects.  We have the appropriate instrumentation and custom solutions to monitor the effectiveness of these developments.  Typical parameters include rainfall, water quality, water level and flow rates.

 

 

Monitoring is performed wirelessly and in near real-time, allowing engineers and stakeholders to see first-hand how their high profile LID project is performing.  Monitoring systems can be setup on a permanent or temporary basis, allowing the user to tailor their program to meet objectives and budgets.

 

Please contact SFE Global for more information on how we can assist with performance monitoring of your LID development.  Mike Lemmen can be reached directly at mike.lemmen@sfeglobal.com, via telephone at 1.866.332.9876, or through our website contact page at www.sfeonline.com

September 2013 – I&I Got You Down and Your Treatment Volume Up??

Manhole Inspection and Rehabilitation Programs from SFE

Repairing leaks in manholes is one of the most cost effective investments to reduce I&I.  SFE crews can stop active leaks with polymer injection and resurface manhhole walls to prevent future leakage. Combine this with sewer flow monitoring, CCTV surveys, smoke testing, and manhole inspection programs and you have an effective I&I abatement program! SFE Global is your one-stop-shop for all these services.

 

Save Money on Treatment and Infrastrucure 

Those bumps around all your manholes are not the manholes moving but the chimneys leaking fill into the sewer!  Repairs like those at right reduce your wastewater treatment volumes and greatly reduce road repairs.

Manhole inspections and rehabilitation are highly scalable and can fit within any budget.  Generally, operations staff know at least a handful of leaking manholes off the top of their head and this is a great place to start.  From there, a manhole inspection program will give engineering and operations staff a prioritized list of manholes to work from.  Whether you rehab five manholes or hundreds of them, rehabilitation can be geared toward available budgets.

 

It should also be noted that you don’t need to wait until your manholes/chambers fail – measures can be taken from the time of installation to ensure long life cycles.  Below are just a few examples of products available from SFE that can be utilized during construction.

 

Please contact SFE Global for more information on how we can assist with manhole inspections and rehabilitation.  Mike Lemmen can be reached directly at mike.lemmen@sfeglobal.com, via telephone at 1.866.332.9876, or through our website contact page at www.sfeonline.com

May 15, 2013 – Got Inflow & Infiltration? Consider Sewer Smoke Testing.

Smoke Testing, or sometimes referred to as Vapor Testing, is an extremely efficient and cost effective investigative method of pinpointing stormwater cross-connections into sanitary sewer systems.  The general approach consists of blowing a low pressure, non-toxic, non-staining, smoke or vapor into the sanitary sewer system.  The result is such that the smoke will fill all sanitary pipes connected to the main, along with any stormwater cross connections that may be present.  Crews then document all exiting sources of smoke via video and picture images.  The final report consists of all video, photos, and detailed test results.  Typical sources of I&I that we find in our smoke testing programs are:

  • Catch basins connected to the sanitary sewer
  • Below grade sewer clean-outs
  • Roof leaders and drain tile cross connected
  • Sump pumps cross connected
  • Detention Pond Overflows
  • Leaky manhole chimneys and frames

Many of SFE Global’s smoke testing programs have immediately located major sources of direct stormwater inflow.  Many feel that smoke testing your sanitary sewers in an effort to locate sources of I&I is the best “bang for the buck” when it comes to assessment options.  Smoke testing typically goes hand in hand with sewer flow monitoring, CCTV, and manhole inspections programs.  This service gives immediate visual results and usually allows Cities to make quick decisions on rehabilitation efforts, sometimes resulting in a dramatic decrease in I&I.

So when is the best time to perform smoke testing?  The vast majority of our smoke testing programs will start in spring and into the summer months.  Best results are achieved when ground water is down and there’s limited chances of high wind and rain.  Poor weather and high ground water tend to limit the effectiveness of your smoke testing program.

Please contact SFE Global for more information on how sewer smoke testing can help you locate your sources of inflow and infiltration.  Mike Lemmen can be reached directly at mike.lemmen@sfeglobal.com, via telephone at 1.866.332.9876, or through our website contact page at www.sfeonline.com

March 15, 2013 – Pipeline Swabbing & Pigging

Pipeline Pigging

SFE Global has been performing pipeline pigging for over 20-years. Whether you’re a City Utilities Director, Engineering Consultant, or Manager of an industrial facility, chances are you’ve come across a pipeline that requires cleaning for one reason or another.   Pipeline pigging has been used for over 50-years as an effective way to clean pressurized pipe systems. As a pigging contractor, SFE Global has the experience and equipment to meet your pipe cleaning needs. Below are just some of the examples of typical pipelines we clean…

  • Domestic and Raw Water Systems
  • Sanitary Sewer Force Mains
  • Sanitary Sewer Siphon Mains
  • Agriculture Irrigation Pipelines
  • Petroleum Products Pipelines
  • Mine Tailings Pipelines
  • Dedicated Fire Suppression Systems
  • Various Wastewater Treatment Plant Pipelines

 

Reasons for Swabbing & Pigging

Here at SFE we generally get one of two calls from our clients with pigging needs; the first is for preventative maintenance measures. Keeping pipelines clear of debris and scale means C-Factors are kept high, friction loss is reduced, pumps are able to operate as intended, pipeline life cycle is extended, and total cost of operation is reduced. The second call we get is due to emergency circumstances whereby a pipeline capacity or water quality has been abruptly diminished. In most cases utilizing the progressive pigging approach we can clear the blockage and renew the pipeline to its original flow capacity.

Results

Depending on your pipeline, you can expect one or more of the following results from pipeline pigging…

 

  • Increase pipe capacity
  • Decrease friction loss
  • Increase pump efficiency while reducing pumping costs
  • Improve water quality
  • Ensure pipelines are clear from all debris
  • Assess potential pipe deformation

January 10, 2013 – Flow Monitoring

SFE Global has been providing sewer, drainage, and industrial effluent flow monitoring services for over 20-years.  Over this time, technology has developed and so have our internal processes and QA/QC procedures that have allowed SFE to continually deliver the excellent services and quality data we’re known for.  As much as technology has changed, the fundamentals of open channel flow monitoring have remained relatively consistent.  Flow rates are generally calculated a few different ways:

  • Area/Velocity Flow Meters – Uses an application specific flow meter that measures velocity and liquid depth through a known geometric shape. (i.e. an open channel round pipe sewer; or box culvert) Once the user has programmed all pertinent information into the meter, it will then record these velocity/depth measurements and calculate a flow rate.
  • Primary Devices –Weirs and Flumes are common examples of primary devices used in open channel flow monitoring.  These devices have known head (liquid level) vs. flow relationships and thus measuring velocity is not required.  Primary devices can transform unfavorable hydraulic conditions into consistent predictable conditions.  In these cases a secondary device is used to rough a known geometric shape. (i.e. an open channel round pipe sewer; or box culvert) Once the user hameasure the liquid depth upstream of the weir or flume and based on the specific head vs. flow relationship, a flow rate is recorded.
  • Hydrologic / Hydrometric / Stage-Discharge Monitoring – There are applications when there’s neither a defined channel nor accessible pipe to measure; and it is not feasible to install a primary device.  Typically in these scenarios the channel bed is profiled at a good stage area in the flow channel and a depth sensor with data logger is used to measure/record level.  Then, over time and at various levels of flow, velocity is manually measured. (using industry standard equipment)  The result is that a stage-discharge curve is developed, allowing for flow rates to be derived from all information gathered.

SFE is not a manufacturer of equipment or instrumentation.  We use the most appropriate technology for the specific application at hand.  Detectronic, HACH/Sigma, Nivus, Isco, ADS, Telog, Campbell Scientific, and Sutron are just some of the flow meter and data logger brands used in our monitoring programs.

Now that you’ve got your flow data recorded in your flow meter or data logger… what’s next?  Stay tuned for next month’s News Update with insights on data acquisition and data management.
