Due to past poor management of the environmental infrastructure, the river has become illegal to swim in in certain parts, and after rain falls the entire river is off limits to swim or fish in due to the heavy amounts of pollution ending up there that the city has not had the infrastructure to deal with in the past.But this all began to change in 2017, when the Virginia General Assembly passed the largest infrastructure project in Alexandria's history to make the Potomac River swimmable, and fishable by the year 2040, and they have made significant progress recently with the completion of the 2 mile long, 100-foot deep Waterfront Tunnel named Hazel.Named after environmental activist Hazel Johnson, the Hazel Waterfront Tunnel will prevent millions of gallons of combined sewage from polluting the region's waterways.

What we do for houses with heating oil , we measure the amount of oil in the tant ( There is a chart that tells yo how many inches equals gallons ) And the tenants pay that up front when they move in , the oil is now theirs .

The solution is to location the meters as close to the billed unit as possible (or even inside) but sometimes that's not convenient because the return and supply lines are on opposite sides of the building whereas you could easily put the meter right next to your boiler / zone valves where all of the pipes are easily accessible.As for cost per BTU, with oil, you keep a rolling average of the price per gallon in your tanks and divide the BTU's used by 138,500 (BTUs contained in a gallon of heating fuel).

Milk is 3 dollars a gallon.
