Flexible Drop Pipe What is it? Polyurethane and High Tenacity Fibers Submersible pump
Drop Pipe Choices Steel PVC HDPE (Polypipe) Flexible Drop Pipe
Cumbersome Installation and Removal
Internal Growth and Corrosion
Flexible Drop Pipe • Operational Depth to 1000ft • No Corrosion or Internal Scaling • 10 Year Warranty - 50 Year Life
Economic Benefits • No Replacement Costs • No Downtime
Economic Benefits • Lower Labor Costs vs
Economic Benefits • Lower Energy Costs Expands 13% Diametrically
Economic Benefits • Lower Energy Costs At 6ft/sec how much time does your water spend in your drop pipe? 60ft = 10sec 600ft = 100sec

Case Study City of Dayton, Ohio – Settling & Filtration Pond
Case Study Over 100 wells All ranging from 100’ – 200’ pump sets. Dayton Ohio
Dayton Ohio Switched from 10” Steel pipe to 8” Boreline
Dayton Ohio Boreline fitting connected to the pump Lowering the Boreline into the well.
Dayton Ohio Lowering the wellhead into position Job completed! Pumping 2600 GPM! Or 3.7M gal/day!
Case Study Phelps Dodge – Miami, Arizona Contaminated Water polluting Roosevelt Dam
Case Study Phelps Dodge – Miami, Arizona 18 interceptor wells to remove groundwater All wells pumping 300gpm from 100ft using 4” tubing Scaling build-up on screen calls for maintenance every 3 months Very costly with rigid column therefore installed Flexible Drop Pipe on all wells
Phelps Dodge – Miami, Arizona Step 1: Connect pump, motor, Flexible Drop Pipe. - All Preparation work done off-site - Controlled environment - Safe Step 2: Drive to site - Clamp hose
