Exploring a massive 12 foot drain, from within another massive drain requires knowledge, planning, physical fitness and wit. Such a treacherous adventure should not be carried out by a casual urban explorer, the ill prepared or weak hands. When this drain was discovered, research seemed to point that this tunnel was draining what was once known as “Jenkins Run”. An ancient stream that was buried & covered over well over a century ago and is the largest stream outfall in the Jonesy system. Every time this tunnel was passed, a strong curiosity beckoned for its penetration. What lies inside was an unknown, granted its overall large size, one could only assume it was the beginning of a large storm sewer network. If subsequent research was on point, it seemed that sizable chambers may lay within. Years later, infiltration was undertaken and the curiosity laced with patience & preparation paid off.
The Jenkins Run Drain empties into Jonesy between Preston and Hoffman streets runs northerly via Carter alley to a point 135 feet north of Lafayette avenue and thence northeasterly to a point in Boone street north of Twentieth street For 3,270 feet to a point in Walcott street it has cross sections of from 163 to 49 square feet and is built with a segmental arch Above this it is circular and 10 feet 6 inches in diameter It drains nearly 900 acres including Homestead and that part of Waverly east of the York Road It has two principal branches
- In Hoffman street to Home wood avenue 4 feet in diameter
- In Girard avenue to Barclay street 3 feet in diameter .
The heading of the tunnel under Guilford avenue has been extended from the entrance of the retaining wall between Biddle and Chase streets to a point 250 feet beyond Preston street a total distance of 8oo feet The heading of the Jenkins Run Sewer tunnel has been extended through to meet the large tunnel a distance of 430 feet The rock excavated from this tunnel is being crushed and used to form the concrete conduits in the bed of the Falls below Chase street. -Source
While this diversion chamber (pictured below) resembles the explorers findings, as much as it looks different.
