<br /> IndividuaI Connection Casts—As noted,the preceding table only includes estimates of
<br /> conshucting the sewer collection system itself. Additional e� r lot costs for connecting to
<br /> � the new system would include the following:
<br /> OWASA Service Availabilitp Fee—This one-time connectian fee represents the
<br /> proportional cost of"buying in"to OWASA's existing facility infrasiructure(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 l,
<br /> 2007 ranges from$2,441 for homes of less tha.n 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 uni�
<br /> A different scale of availability fees applies to non-residential sewer connections.
<br /> Private Plnmbing Costs—The pipe that e�ctends from a building to the OWASA sewer
<br /> line is called a lateral. ITnlike pipes in OWASA's system,the lateral is part of the private �
<br /> property served by the public sewer. Installation and mai.ntenance 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 foo� Tha.t is,installation of a 50-foot lateral would cost
<br /> approxinnately$1,254, a 100-foot lateral would cost appmximately$2,500,and so forth.
<br /> SevPer Tap Charge—This fee is for physically connecting the private sewer lateral to the .
<br /> OWASA sewer line. The base ta.p chazge, effective as of October 1,20Q7,will be$318.
