To keep up with the growing population on the Broadneck Peninsula, county officials are planning to double the capacity of the Arnold Water Treatment Plant from 3 million to 8 million gallons a day.
The county has begun advertising for bids on the project, which includes building three new aerators and six gravity filters and digging a fifth well with a depth of 1,000 feet, said Vijay Kulkarni, chief of facility engineering for the Anne Arundel County Department of Public Works.
The upgrade will cost the department about $10 million, Mr. Kulkarni said. The bids are to be opened in December and construction is to begin in March.
"Essentially, the whole Broadneck area has seen a significant rise in housing," Mr. Kulkarni said. "As the demand increased and development increased, we have to keep up with the demand."
Population in the area has increased from 68,616 in 1990 to 69,494 in 1995, according to Sandy Speer, county demographer.
Demand per home has also increased, Mr. Kulkarni said.
Mr. Kulkarni said the demands on the plant have grown so much that operators had to use an auxiliary well to pump water during the dry spell this summer.
"We were having a hard time meeting the demands in the area during the summer," he said.
