Analyzing The Bread & Butter Benefits of Sewer Main Pipebursting Matt Werth General Manager PM Construction
Pipebursting is the answer to many very difficult rehabilitation needs where there are almost no other options.
City of Dallas Pipebursting a 36 RCP to a 42 HDPE
Large, difficult projects are impressive and make for great presentations but I ll let you in on a little secret.. 95% of all pipe burst projects are 8, 10, and 12 diameter.
Things I have learned to be true about utility construction..
1. The Public is VERY understanding when it comes to construction projects near their home.
2. Businesses are EVEN MORE understanding than the public when it comes to utility construction.
3. Utility owners have an unlimited budget to maintain their system.
The small diameter projects may not be as glamorous but they are more realistic and the life blood of our industry. This presentation will cover the everyday pipeburst projects and highlight the benefits to: The Public / Rate Payers Businesses BUDGETS
Underground Infrastructure 1. Pipelines are one of the most expensive assets a municipality owns and many times the most ignored (out of sight out of mind) 2. More and More municipalities are being put under consent order by the EPA and are being mandated to rehabilitate their system 3. It is estimated that over 300 billion dollars is needed for Sanitary Sewer repair by 2020.
Bread and Butter Benefits of Sewer Pipe Bursting Sanitary Sewer Overflows - The public could care less about their sewer system until that sewer system shows up on the floor of their home - Pipe Bursting is a very fast, efficient method for rehabilitation of mains and laterals
Bread and Butter Benefits of Sewer Pipe Bursting Pipeline deterioration is the problem, but why is pipe bursting the solution?
Bread and Butter Benefits of Sewer Pipe Bursting Small Footprint - Pipebursting requires a fraction of the excavation that is necessary for open cut replacement (see typical pipeburst layout below)
Bread and Butter Benefits of Sewer Pipe Bursting Small Footprint - Pipebursting allows for flexibility of access points and areas where excavation can take place
Bread and Butter Benefits of Sewer Pipe Bursting Ability To Upsize While Still Using a Trenchless Method - Pipeburst Is the only trenchless rehabilitation method that allows you to upsize the sewer main
Bread and Butter Benefits of Sewer Pipe Bursting Pipebursting is easier to design, plan, and execute
Bread and Butter Benefits of Sewer Pipe Bursting Less Restoration Because you don t have as much excavation with pipebursting it means you have less restoration (this allows for increased cost savings): 1. Stone Backfill 2. Asphalt Pavement 3. Concrete 4. Utility Relocation 5. Traffic Control 6. Bypass
Bread and Butter Benefits of Sewer Pipe Bursting Cost Savings Example project Open Cut vs Pipe Bursting Item Description Unit of Measurement Open Cut Pipe Bursting Mobilization one one one Pipe 1,000lf 8 pvc 8 HDPE Traffic Control Per/day 12 5 Excavation Sq/yard 1777 99 MH Replacement each 4 0 By-Pass Pumping Per/day 12 4 Business Disruption Per/day 15 5 Dewatering Per/day 12 3 Pavement Sq/yard 666 43 Service laterals each 4 4 Total Cost $275,000.00 $125,0000.00 This doesn t even include savings on construction inspection
Bread and Butter Benefits of Sewer Pipe Bursting Environmentally Friendly - Trenchless Methods don t put out near the amount of emissions that other rehabilitation methods do - The reduction in excavation allows us to use less stone for backfill keeping from stripping more unnecessary natural resources
Bread and Butter Benefits of Sewer Pipe Bursting Conclusion It is important to remember that pipebursting is a viable option for everyday pipeline rehab projects not just Presentation projects where there are no other options. The benefits of pipebursting are clearly seen in the efficiency, the simplification of design, and through cost savings.??????? QUESTIONS????????
