Forcemain Cost estimates

Forcemain Cost estimates

Forcemain Cost estimates

(OP)
I have been given the task of comparing two altertnates.
Either build a WWTP on site for treating industrial/domestic waste or construct a sewer force main to take the waste 10 miles and connect to an exist sewer system. I am starting with the second alternate, meaning estimating the cost of a 10 miles forcemain. Can anyone give me some help regarding:

-- Some documentation on parameters to consider for the design of a FM.
-- Types and cost of pipes, lift stations, etc.
-- Some hydraulic models
-- etc.

any help  will be greatly appreciate.

Thank you.

--Doc. on parameters to consider:

http://164.156.71.80/VWRQ.asp?docid=2087d8407c0e00000000035400000354&context=2&backlink=WXOD.aspx%3ffs%3d2087d8407c0e00008000031500000315%26ft%3d1

for the design of a FM: pages 28-35,
for the design of a WWTP: pp37-111,

but your state/province will have their own...use that one.  The guidelines will be similar enough for prelim. cost estimating.

--costs:
WWTP will require an Operator forever, PS will require substantially less O&M.
Other costs vary too much w/out more info, but I would guess a small package WWTP might be more attractive than 10 miles (!) of FM.

--hydraulic model:
Use Hazen-Williams.  Use smallest D at known L and Q to get reasonable hf.  Apply to Bernoulli's, with known z and v, to get dP.  That will size pump.

RE: Forcemain Cost estimates

Uni-Bell PVC Pipe Association has a brief manual called Forcemain Design using PVC pipe, and they also sell a Handbook of PVC PIpe, very informative.  Also could contact IPEX in Canada or US who provide tech, info. on PVC and other plastics (www.ipexinc.com).
