Case Study #2
Study #2
Project Lead: Jack Berry
Project Summary: Jack Berry successfully cleaned and disinfected a newly installed 8-inch ductile iron water supply line. Traditional cleaning methods, including multiple flushings, chemical injections, and tests, had failed.
Challenge: Despite multiple cleaning attempts, the new water supply line remained unclean. Traditional methods were ineffective, requiring Jack Berry's intervention.
Solution: Jack Berry devised a plan to clean and disinfect the pipeline using eight poly pigs (cleaning devices) pushed through the line with less than 200 gallons per minute of flushing water treated with pool shock (NSF 61 certified). He also secured approval from the water district for an 8-inch hydrant branch to launch the pigs.
Process:
- A series of 6-to-12-pound poly pigs were inserted into the hydrant branch.
- A flow-through plug was inflated and supplied with clean water.
- Each pig pushed debris out of the pipeline, with subsequent pigs encountering progressively less debris.
- Following cleaning, a test was conducted, and the line passed inspection, allowing development to proceed.
Benefits:
- Successfully cleaned a new pipeline that previous methods failed to address.
- Completed the project efficiently, avoiding further delays.
- Berry Consulting possesses the resources to clean and disinfect smaller diameter pipes (4", 6") on short notice, with slightly longer lead times for larger pigs.
