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
Arrangements have been made for a block of sleeping
rooms at each hotel where the seminars are being held.
Special hotel rates are available to seminar attendees. A
hotel registration card will be sent to you with a letter
confirming your registration for the seminar.
Seminar registration is free and you may register for any
one of the three seminars. We do request, however, that
you return your registration form early as each seminar
will be limited to 300 participants.
