CHANHASSEN, MINNESOTA
SUMP PUMP INSPECTION PROGRAM UPDATE
7/7/97
1. TOTAL INSPECTIONS COMPLETED AS OF 6/30/97 - 4,461
2. PROPERTIES IN COMPLIANCE WITH CITY ORDINANCE - 4,040
3. PROPERTIES NOT IN COMPLIANCE WITH CITY ORDINANCE - 421
A. Of the 421 non - compliance properties 226 are sump pumps
pumping into the sanitary sewer system.
B. Of the 421 non - compliance properties 195 are sump pumps
with flexible hose discharges.
4. PERCENTAGE OF PROPERTIES IN COMPLIANCE - 90%
5. PERCENTAGE OF PROPERTIES NOT IN COMPLIANCE - 10%
Based on the more than 4,000 inspections to date, many sump pumps that were found to be
in compliance with the City's sewer use ordinance had been changed prior to the
inspections due to the public informational program. Therefore, the percentage of
properties that were found not to be in compliance during the initial inspection was
substantially larger than the figures indicate above.
Also, the inspectors have noticed that many of the flexible hose discharges that were
pumping outside at the time of the inspection had in the recent past been pumping into the
sanitary sewer. The inspectors found in many cases that the discharge hose had the tell tale
brown color on the discharge end indicating it had been connected to the basement floor
drain. The City's sewer use ordinance as amended providing for rigid piping will eliminate
most of the problems of property owners moving the discharge back and forth from the
sanitary sewer.
As of 7/7/97 all sewered properties in the City of Chanhassen have been canvassed twice for
the initial inspection. We estimate approximately 400 properties still need to be inspected
at this time. A final list of all properties not inspected is being developed based on the PID
number. This list will be reviewed and a third canvassing of those properties will be
completed in the next month.
Upon completion of the third canvassing of those properties not initially inspected, a letter
will be sent by the City to all property owners not initially inspected requesting their
cooperation in having the inspection completed.
The sump pump inspection program has uncovered a number of areas within the City
where ground water problems make the disconnection of sump pumps from the sanitary
sewer system a problem. The City is working with these property owners and
neighborhoods to develop long term solutions to these ground water problems.
Re- inspection of properties which were found in non - compliance with the City Ordinance
is continuing as property owners make repairs.
A preliminary report to the Metropolitan Council Environmental Services is being
prepared at this time for submittal in the fall of 1997 as part of the Loan /Grant received by
the City for the funding program for this project.
The cooperation by the vast majority of property owners has been fantastic. Many positive
comments have been received by the Buchen Staff regarding the City's approach to saving
taxpayer dollars by eliminating the costs of treating the clear water from the sump pump
discharges.
