DWQ Project# 02-1489
Dewberry Project Number 02096
Dear Ms. Karoly:
Per your letter dated October 28, 2002 and per our phone conversations, on behalf of the City of
Raleigh, we are enclosing the following:
• Preliminary construction drawing, including topography along the proposed construction
corridor. (7 copies)
• Photographs of area along proposed route of water main. (7 copies)
We understand the DWQ is willing to reopen the permit application process and allow this
additional information to be provided.
Below are responses to the information requested in your letter.
1. Comment: Directional drilling crossing would have less impact on Walnut Creek streambed.
Response: Yes, it is true directional drilling would have less impact on the Walnut Creek
streambed than an open cut. However, the Walnut Creek streambed was recently
disturbed when the road was constructed.
2. Comment: Does City of Raleigh have directional drilling equipment? Can this directional
drilling equipment be rented or can a contractor be hired to perform the directional
drilling?
Response: No, the City of Raleigh does not have directional drilling equipment, nor is it
feasible to rent this equipment. Yes, the City of Raleigh could hire a contractor to install
the directional bore.
3. Comment: If the directional drilling crossing is prohibitily expensive, please provide
documentation on the cost of directional drilling versus open cutting.

Response: Directional drilling for the crossing is prohibitly expensive. The City of Raleigh
does not allow the type of material (HDPE) required for directional bores to be used for
water mains.
The following is a cost comparison between directional drilling, traditional bore and
jack, and open cut.
Directional Bore Method
Item Description Quantity Unit Unit Price Total
1. 16" HDPE Pipe, SDR 9 150 LF $120 $18,000
2. PE/MJ Transition Assembly 2 EA $2,000 $4,000
3. Concrete Thrust Collars 2 EA $3,500 $7,000
Estimated Total Cost $29,000
Bore and Jack Method
Item Description Quantity Unit Unit Price Total
1. 16" DI Pipe with Field Lok
Gaskets 90 LF $50 $4,500
2. 30" Steel Encasement 90 LF $445 $40,050
3. Concrete Thrust Collars 2 EA $3,500 $7,000
Estimated Total Cost $51,550
Open Cut Method
Item Description Quantity Unit Unit Price Total
1. DIP Pipe with Field Lok
Gaskets 90 LF $60 $5,400
2. Erosion Control 1 JOB $3,000 $3,000
3. Concrete Thrust Collars 2 EA $2,000 $4,000
Estimated Total Cost $12,400
The length of pipe used for the directional bore method is more than the other two methods,
because of the limitation of insertion angle (no more than 11 degrees) of the directional bore and
clearance required beneath the creek's channel.
The City has attempted to cross the creek by the bore and jack method. But due to poor soil
conditions and the high water table, the pits for the bore and jack method failed. This was
attempted twice. If the directional bore method is attempted, then there is a high potential for the
directional bore pits to also fail. If the directional bore method is attempted and the appropriate

entrance and exit pits cannot be excavated, the length of the directional bore will increase,
increasing the cost (Directional Bore Method) listed above.
The City of Raleigh requests approval to install the water main by the open cut method. The
open cut method is constructable, cost effective and environmental impacts will be minimal.
Should you have any questions or comments, please do not hesitate in calling our office.
