PURPOSE

The  purpose  of this  seminar is to present  the  latest
information  on planning,  designing,  and  managing
wastewater treatment facilities for small communities.
Individual systems, as well as community-wide systems,
will be covered. The 1977 Clean Water Act (P.L. 95-217)
imposes no restrictions on types of wastewater treatment
systems; individual (on-site) systems, both  publicly and
privately-owned, are eligible for funding.

Technical  sessions will be  conducted by  nationally
recognized experts. These speakers have extensive field
experience  in the area of treatment systems  for  small
communities.  Ample time has been alloted for interaction
between  speakers  and attendees  in  the   technical
sessions.

REGISTRATION AND HOTEL INFORMATION

There is no seminar registration fee. Attendance will be
limited to 300  participants. To register fill out theattached
