A new aerated sewage lagoon is required in a small town in 2020. In 2015, one was built on a similar site in a nearby city for $3 million.The new lagoon is 75% larger, and its power sizing exponent is 0.90. The cost index for 2015 is 180, whereas the one in 2020 is 400. Estimate the cost of new lagoon in 2020.
Solutions
Expert Solution
Real Cost of new =Real cost of old*(size of new/size of old)^n where n is power sizing exponent
So, Real cost of new lagoon=$3,000,000*(1.75)^0.9=$4,964,271.2
Nominal cost=(new cost index/Base cost index)* Real cost=400/180*4,964,271.2=$11,031,713.8 or ~$11mm

A conventional non-aerated lagoon with a hydraulic retention
time of one year is used to treat domestic sewage in a wastewater
treatment plant. The plant needs to be upgraded to handle a larger
wastewater flow rate and to improve the removal of nutrients. List
three treatment system upgrades (by using process
diagrams) that can be done to the existing lagoon, and
provide a schematic diagram for each upgraded process. What do you
think the best choice between the three upgrades you...

Joe has just moved to a small town with only one golf course,
the Northlands Golf Club. His inverse demand function is
p=140−2q,
where q is the number of rounds of golf that he plays per year.
The manager of the Northlands Club negotiates separately with each
person who joins the club and can therefore charge individual
prices. This manager has a good idea of what Joe's demand curve is
and offers Joe a special deal, where Joe pays an...
