The York Water Company announced Wednesday revenue in the first quarter of this year increased from the same time period last year.

First quarter operating revenue for 2013 topped off at $10,069,000, an increase of $400,000 over last year, President Jeffrey Hines said in a news release.

Net income also increased by $198,000 in the first three months to $2,139,000 compared to the first quarter of 2012, the release said.

The higher revenue is credited to an increase in the Distribution System Improvement Charge, a surcharge allowed by the state Public Utility Commission to replace aging infrastructure, and a growing customer base, Hines said.

Earnings per share for the first quarter increased $0.02 compared to the same period last year.

From January through March, the company invested $2.4 million in infrastructure replacement projects.
