2.103 -C- information on the existing sanitary storage facility located near Yost Blvd at Salem Ct/Margaret Drive.

Posted by Lori Byron on 5 Feb, 2014
Category: Category 2 - about potential recommendations

Q. Provide information on the existing sanitary storage facility located near Yost Blvd at Salem Ct/Margaret Drive.

A: This facility was installed in the late 60’s to provide relief for the Swift Run trunkline. The facility consists of three 54”x85” arch pipes which can handle 118,613 gallons of storage, and is still in service. The need for additional relief was identified in the late 1990’s which led to the construction of a relief sewer further downstream from this existing storage facility.

Apparently it is not enough. A good friend of mine who lives on Lillian St a few houses north of Terhune told me during a Super Bowl party that he has had sewage back up into his basement. He is at the bottom of a hill.

The location of this holding facility is interesting, as it appears to be under the grass of a park. If storage were decided to be the best option, this could be a location, under baseball diamonds and soccer fields.

Note that this question was also asked in another message that included the Bluett & Georgetown area. A response to both is included below.

The facility near Yost Blvd (not Yost arena) & Salem Ct was installed in the late 60’s to provide relief for the Swift Run trunkline. The facility consists of three 54”x85” arch pipes which can handle 118,613 gallons of storage, and is still in service.  Refer to the attached record drawing (Swift Run Storage Drawing.tif) for more information.  The facility is located in open area adjacent to the Swift Run drain.  The need for additional relief was identified in the late 1990’s which led to the construction of a relief sewer further downstream from this existing storage facility.

The facility in Bluett & Georgetown consists of a 58” x 94” arch pipe installed in 1969, which can handle 149,012 gallons of storage, and is still in service.  The facility is located in the road right-of-way.  Refer to the attached record drawing (Bluett Storage Drawing.tif) for more information.  In the late 1990’s and early 2000’s the area still experience numerous basement backups, which resulted in this area becoming one of the FDD study areas. 

Conflict with existing utilities is a valid concern and will need to be considered during the alternative analysis phase when looking at storage as a possible alternative.
