Water Plant Upgrade

TANKS’ LEVELS DROPPING

Perched on the fall line of the Coastal Plain, the City of Emporia has historically been a commercial hub in Southside Virginia. The area along the Meherrin River was first explored in 1670. The Town of Hicksford was settled in 1710 where the Fort Road of eastern Virginia crossed the Meherrin River en route to Fort Christianna. The Town of Belfield incorporated in 1798 on the north bank of the river. The two Greensville County towns merged in 1887 to form Emporia, which received a city charter in 1967. The City of Emporia (pop. 5,700) is the southern gateway to Virginia. Just eight miles from the North Carolina line, it is the first municipality on I-95 heading into Virginia. Emporia is also at the crossroads of two key railroads – CSX running north-to-south and Norfolk-Southern going east-to-west. The accessibility to major rail and highway routes contributes to a growing industrial base. One purpose for the water plant upgrade is to help supply water to a future industrial park mega site that will utilize the City’s crossroads’ location at two major railways and Interstate 95 and Highway 58. Currently the City of Emporia owns and operates a conventional 4.0 million gallons per day (MGD) water treatment plant (WTP) located along the western limits of the City of Emporia. The raw water intake is in the Emporia Reservoir on the Meherrin River. The facility was originally constructed in 1954 and provides water to the citizens who live within City of Emporia limits. While the design capacity of the plant is 4.0 mgd, it currently operates with a monthly maximum around 1 mgd. Given the high capacity and the facility’s location on the single largest water supply source in the region, there is potential to support a much larger service area.

Recently, I visited the City of Emporia’s water treatment plant. While speaking with Water Plant Superintendent Tom Delbridge about the recent hiring of two new operators and getting them ready for licensing, I noticed a configuration of control panels and membrane filtration tubes under a metal roof. Curiosity always wins, so I inquired about the set-up. Delbridge explained that this was a beta test for collecting data for a purposed upgrade at the water plant that would start soon if the filters performed as designed. Observing the project from the beginning would make an interesting article, so I asked if Delbridge would mind sharing the project from start to finish. The “go ahead” was given after checking with all parties involved. This is the first in a series of articles that will show and explain the process of a water treatment plant expansion as the utility brings the project to completion. Thanks go to Tom Delbridge, Water Plant Superintendent; Linwood Pope, Public Utilities Director; and Arthur Buckner, Water Plant Operator, all with the City of Emporia; Dan Villhauer, PE and Richard Kincheloe, EIT with Dewberry; and Steve Childers with Heyward Incorporated. Their time and input were invaluable, as they explained the designs, processes and performances of various systems. It was February 1998 when I met Tom Delbridge and Larry Epps. Emporia hosted a VRWA training class. Afterward, I asked to tour their plants. Larry showed me the wastewater plant, then called Tom Delbridge to see if we could stop by the water plant. It was 6:30 p.m. and Tom said to come on over. That the two men took the time, after hours, to show and explain the processes to a “beginner” in the industry, demonstrates the dedication, commitment and pride that are exceptional to this trade.
