Gentlemen:
On December 23, 2002, Veit & Companies televised the 12" sanitary sewer installed by LaTour
Construction as part of the City of Albertville's Northwest Commercial Park project. This sewer
extends from Towne Lakes First Addition, westerly through Towne Lakes Second Addition, to the
Commercial Park. The televising revealed a crack in the service pipe and wye at Lot 9, Block 6, of
Towne Lakes Second Addition.
Since the sewer was installed by LaTour Construction, the remainder of the municipal
improvements were installed by Hennen Construction. This work included installation of. water
main, storm sewer, and extension of the sewer services from the risers to the individual lots. At this
time, it is unclear how the damage occurred, when it occurred, or what caused the damage. What is
known, is that the damage needs to be corrected. An initial step is to determine the extent of
damage. Enclosed is a proposal from Infratech Technologies to provide lateral televising of the
service in question. This televising should help determine the extent of damage and may provide
more insight on how the damage occurred.
The City of Albertville is taking the initiative to determine the extent of damage and possibly have
the damage corrected as they see fit. Please be aware the cost for this work will be passed onto the
responsible party.
Please call me if you have any questions.
Sincerely,
r~g.~I~
