<br />individual properties to the sewer system are discussed in the section below.

<br />Individual Connection Costs — As noted, the preceding table only includes estimates of
<br />constructing the sewer collection system itself. Additional ep r lot costs for connecting to
<br />the new system would include the following:
<br />OWASA Service Availability Fee — This one -time connection fee represents the
<br />proportional cost of "buying in" to OWASA's existing facility infrastructure (main sewer
<br />lines, treatment plant, etc.) and is assessed according to the square footage of residential
<br />properties. The sliding scale of availability fees that will be effective as of October 1,
<br />2007 ranges from $2,441 for homes of less than 1,300 square feet to $4,514 for homes of
<br />greater than 3,800 square feet. Fees for multi- family residences will be $2,645 per unit.
<br />A different scale of availability fees applies to non - residential sewer connections.
<br />Private Plumbing Costs — The pipe that extends from a building to the OWASA sewer
<br />line is called a lateral. Unlike pipes in OWASA's system, the lateral is part of the private
<br />property served by the public sewer. Installation and maintenance of the lateral is the
<br />responsibility of the property owner, who typically contracts with a private plumber for
<br />installation. Costs depend on several factors, especially the distance from the building to
<br />the OWASA sewer line. A recent telephone survey of several local plumbers indicated
<br />prices in the range of $25 per foot. That is, installation of a 50 -foot lateral would cost
<br />approximately $1,250, a 100 -foot lateral would cost approximately $2,500, and so forth.
<br />Sewer Tap Charge — This fee is for physically connecting the private sewer lateral to the
<br />OWASA sewer line. The base tap charge, effective as of October 1, 2007, will be $318.
