I asked Joni Wilson, UMW Director of Landscape & Grounds about the yellow water. She spoke with Dan Quann, Mechanical, Electrical and Plumbing Manager, who explained that the discoloration was the result of water hydrants being flushed in connection with the Randolph and Mason construction project.
Apparently the water was technically safe, but would not have tasted good…
As we know, over time metal pipes normally collect deposits from the water running in them, but when the water flows in one direct little to no evidence of those deposits is seen. When the hydrants were flushed, the water flowed in the opposite direction for a time. This caused turbulence and a back-wash effect that led to those deposits being stirred up and dissolved in the water again, thus causing the discoloration.
For UMW as well as the rest of the city, domestic water is on the same loop as fire hydrant water; so when you flush hydrants, you can disturb domestic water…
Dan gave Joni some ‘City of Fredericksburg Water Distribution System 2009 Annual Water Quality Reports’, which she will give me – but I think I found the link online.
This page describes the report and what it shows; this page shows the data – looks like our water is pretty good.
I also found that the city has put out a request for proposals to be submitted for a study of the water and sewage management system – you can read that here; the introduction states,
“The City of Fredericksburg is seeking qualified management and consulting firms to perform a
thorough financial and management analysis of the City’s water and sewer systems. The City
specifically desires recommendations with regard to two areas:
1) The adequacy, equity, and efficiency of the City’s current fees and charges for
service; and
2) The efficiency and effectiveness of the City’s current organization concerning water
and sewer services.”
Interesting – relating to this class, one hopes that they are looking for efficiency in running both treatment and sewer systems as well as maintaining or updating the infrastructure of the system.
Since I’m on the Fred water web site, I thought I’d post info about domestic pricing, which you can read about here. This page allows one to calculate rates; my water meter (for a 4-bedroom house) is the first on the list, so I pay a base rate of $7.45 and then $0.185 per 100 gallons of water used; for sewer (which is, of course, inseparable even if my used water goes for watering plants, not down the sewer!), I pay a base rate of $8.56 plus $0.386 per 100 gallons. Note that sewer is more pricey than water – which makes sense if the water is from a fairly clean source, the city has to do more to clean up the sewer water than to clean up the water I am about to use… If I use none, my bill is $16.01.
My normal water & trash bill is just over $100 every 2 months, so about $50/month. The trash portion is $15.75, so water & sewer is close to $35. Subtract the required ‘base fees’ ($16.01) and I’m paying about $19 per month for clean water delivered to my house and dirty water taken away. Phenomenally low, I think… I doubt that my family would use less if we paid twice as much.
