Subject: Sanitary Sewer capacity regarding Cappelli project
George,
As per your request and yesterday’s discussion, we have investigated the capacity of the City’s sanitary sewer system so as to determine if it will be adequate to cope with the loads from the City Center project.
Although the developer is now performing actual flow meter tests in various S/S (sanitary sewer) manhole locations downstream of their project site, we did manual observations of the outfall pipes. Note that these pipes are between fifteen and twenty feet below the surfact of the roadways, and the measurement of fluid level entailed our men going to the bottom of these manhole shafts at hourly intervals last night and this morning. While there was expectedly a lull in flow after midnight, it picked up again after 4:00AM and was never found to be much below the 75% level throughout the day and into the evening. In many instances (particularly near the Martin Luther King Blvd. intersection with Main St.- where the 16” diam. Line connects to the newer 27” and then quickly to a 30”) we noted the pipes to be running very close to design capacity. Of course, this is with the present building load. The additional sewage from the Cappelli project will easily overload this length of pipe and cause catastrophic backups. Further the current 8” pipe which resides in Main Street between City Hall and the City Center site is now running at 40% capacity and will definitely need to be replaced with a larger pipe, say 16”, in order to handle the discharge from the north apartment tower and the movie theater. This small line (the minimum size for a munipal S/S main) is very old (constructed of clay) and serves very little else at the present time, other than the Fleet Bank, City Hall and Halpern’s office building next door to us at 245 Main Street.
We have also done a cursory cost estimate to install ductile iron pipe of a large size in the necessary areas:
Replacement of the present 8” clay tile pipe from a manhole on Main Street, just West of Conroy Drive, to the intersection with Mamaroneck Ave. will require about 470 linear feet of pipe. We have never seen sewer pipe replaced for less than $100/ft. in recent years, but because of the location, depth, preponderance of existing underground utilities, and the need to replay the new pipe in the exiting pipe’s trench, We would estimate costs to be more on the order of $300/ft. The depth of the pipe requires significant sheeting and shoring, and the many other utilities will need to be temporarily rerouted during construction (gas, electric telephone, fiberoptic cable and numerous lateral service lines will be in the way). As the roadway carries significant traffic volumes, shortened work days (or late night construction hours) will need to be instituted and expensive traffic control and protection devices will be required. Finally, since there is no alternative corridor for the new line to occupy, it will have to go in the original pipe’s trench, thus requiring a bypass pump system to operate while the old line is taken out of service. Estimate a this time: $150,000.00.
The second piece of this concerns the existing 16” and 18” lines which connect on Main Street between Mamaroneck Ave. and Martin Luther King Blvd. This line is even deeper than the aforementioned 8” line and owing to its even more critical location in Main Street, we project costs to be $500/ft. This results in a value of about $500,000.00 for its 1,150 foot length.
In short, based upon present information and our historical experience, the total sanitary sewer work necessary to support the City Center project (commercial and residential components) is estimated to be $650,000.00 exclusive of design costs, construction management, and as-built certifications. This could amount to an additional $100,000.00. We stress that these costs are only projections, and that the project would need to be fully designed first in order to get better accuracy, and then put out to bid to test to market reaction to the difficulty of the job.
Thanks,
Bud
