So my 74 pad park has very old galvanized water lines in some sections, and we’re suffering fluctuating water pressure at the ends of the lines.
We’ve hired an engineering company to advise us (not easy, the first 10 engineering companies I called were too busy to take on our project) and $4,000 later they’ve built models of our system and are recommending a looping of the system which they project will easily solve the water pressure problems.
They’re predicting the permitting process and working with both the township and the state to be difficult in post Flint crisis Michigan, and are predicting around $12,000 in soft costs on the high side for engineering plans, permits, revision of plans after requests from the state/township, etc. The current plan is proposing the addition of 900 feet of new water lines, and 7 new home taps, for a rough estimated cost of $60,000 on the high end (but this hasn’t been bid out to contractors yet)
I’m obviously not happy about a fix that’s this expensive, but it doesn’t seem like we have many other options. (fwiw, two engineers estimated replacing the entire system would cost $250,000-$300,000 to replace)
I was just curious to put this out here, see if anyone else had done similar work, and see if there’s anything I should keep my eye out for. It seems pretty straightforward, but figured it doesn’t hurt to ask if there’s anything obvious I should consider.
