City eyes contract for groundwater well design

By

Pickerington is in the process of enlisting the services of HDR Engineering Inc. to design a new groundwater well to help meet its increased demands for water.

May 7, City Council heard a first reading of an ordinance that will authorize City Manager Bill Vance to enter into a professional services contract with the Columbus-based company for the city's "Groundwater Well No. 8 Project."

The project is part of the city's Capital Improvement Plan with $80,000 budgeted for the design in 2013 and $500,000 projected for construction in 2014.

HDR Engineering's design proposal is tabbed at $77,900.

Gary Armentrout, chief operator of the Pickerington Division of Water, said the city needs another well because "with the addition of reverse osmosis treatment units we are short on capacity."

He said the current city well field has four wells with a total rated capacity by the Ohio Environmental Protection Agency of 4,000 gallons per minute.

However, the largest well, rated at 1,400 gallons per minute, is out of service.

"That gives us 2,600 gallons per minute rated capacity," Armentrout said.

Thus, the production goal for the new groundwater well is 1,400 gallons per minute.

"The new well will be located in the existing Diley Road well field," Armentrout said.

"The current plans call for drilling and construction in 2014," he said.

The Groundwater Well No. 8 Project was previously discussed at the City Council Service Committee meeting April 17.

City Councilwoman Cristie Hammond inquired at that meeting whether the city would "at some point have to look for more land for wells."

Engineer Greg Bachman stated that as part of the well design the city will be investigating which aquifers to drill.

He said there is an upper aquifer, where the city's existing wells are located, and a lower aquifer.

"If we go to the lower aquifer they should have a higher yield," Bachman said.

"Part of that design may answer that question," he said.

HDR Engineering Inc. also was chosen by the city to handle the design of the Leasure Drive Pump Station project.

That project is being done to accommodate the expected increased sewage generated from the future 60-acre Ohio Health medical campus on Refugee Road.

Pickerington's 2011 "Sanitary Sewer Master Plan" also targeted the pump station for expansion, citing the substantial growth of the city since it was initially constructed.

According to City Engineer Greg Bachman, capacity at the pump station will increase from 2.1 million gallons per day to 4.5 million gallons per day once it is completed.

The Leasure Drive Pump Station project is estimated to cost Pickerington $850,000, which will be paid for from the city's Sanitary Sewer Fund.

"We have a contract with HDR for $88,500 to design the project," said Ed Drobina, Pickerington Service Department manager.

"The plans have been approved by the Ohio EPA and the project will go out to bid in the next few weeks," he said.

"The start date has yet to be determined."
