DOWNSPOUT INSPECTION PROGRAM
        SUMMER 2006


    FINAL PROGRAM REPORT
Introduction


In the summer of 2006, the Downspout Inspection Program began as a component of the
City of Welland’s Water Conservation Program. City staff conducted inspections of
building roof downspouts and associated lot drainage on residential and commercial
properties in selected areas of the city with a history of basement flooding. Information
obtained in these inspections will be incorporated into existing inflow and infiltration
studies which are currently underway for these areas. The first of these areas to be
inspected were the Broadway and Clare Avenue areas (Appendix A and Appendix B
respectively).


Inspections took place with the intention of identifying downspouts that discharge rain
water from roof surfaces to the sanitary sewer via direct connections or indirectly to
building foundation weeping tiles. The program’s objective was to eliminate these direct
and indirect connections to the sanitary sewer, in accordance with by-law #3913
(Appendix C) by informing the public of the importance of disconnection as a flood-
proofing preventive measure.


Improper routing of downspouts and poor lot-grading and drainage can contribute to
basement flooding and combined sewer overflow to the environment. Residents were
encouraged to reduce their property’s rainfall contribution to the sanitary system through
proper lot grading around the home’s foundation, removal of downspouts and yard storm
drains directly connected to the sanitary drain, proper extension of downspouts away
from the home’s foundation, and proper use of a sump pump.


During intense rainfall events, a large volume of rainwater can enter and overload the
municipal sanitary sewer system, and/or undergo unnecessary treatment at the sewage
treatment plant. Instead of being treated, this storm water should be reused or discharged
to the environment, to save the City and its taxpayers money on treatment costs.
Program Objectives


  1)   To reduce the potential of a sanitary sewer overload, associated sewer back-ups
       and/or basement flooding events.
  2)   To identify downspouts that discharge rain water from roof surfaces to the
       sanitary sewer via direct connections or indirectly to building foundation
       weeping tiles.
  3)   To eliminate indirect and direct connections to the sanitary sewer, in accordance
       with by-law #3913.
  4)   To inform the public of flood-prevention measures to assist property owners in
       resolving flooding and back-up issues.
  5)   To obtain information for incorporation into existing inflow and infiltration
       studies currently underway for the Broadway and Clare Avenue areas.
  6)   To obtain an inventory of storm water inflows and infiltration sources into the
       sanitary sewer system.
  7)   To obtain an inventory of surficial lot drainage characteristics.
  8)   To assess the need for new by-laws and design standards to regulate storm water
       runoff.
  9)   To reduce the costs incurred by the city of Welland for unnecessary treatment of
       storm water.
Methodology


The Downspout Inspection Program emphasized the importance of disconnecting
downspouts from the sanitary sewer, in addition to proper lot drainage and installation of
appropriate downspout extensions. City staff conducted visual inspections of building
roof downspouts in selected areas of the city with a history of basement flooding. The
first areas to be inspected were the Broadway and Clare Avenue areas (Appendices A and
B).


An inspector from the City of Welland’s Water Conservation Program visited each
property to offer information regarding the downspout program and to perform the visual
on-site drainage inspection. An inspection sheet was completed for the purpose of
drainage data collection, along with an interview of the homeowner or occupant to
acquire relevant information regarding flooding history and existing basement conditions
(Appendix D; Inspection Sheet and list of definitions).       This inspection sheet was
designed for the purpose of this program and facilitated efficient data collection in the
field.


Good communication between City staff and residents was the focus of our selected
inspection approach. Residents of the Broadway and Clare Avenue areas received letters
in advance of the inspections with information regarding upcoming visits from Lot
Drainage Inspectors to their neighbourhood (Appendix E). All completed inspections
have an interview component and residents were given the chance to participate in the
inspection process and/or ask questions at any time during the inspector’s visit. A better
understanding of drainage situations and their impacts was expected to increase the
public’s compliance with suggested repairs.


Following the inspection, the informative “Break the Connection” brochure was left
behind (Appendix F). Inside the brochure, residents have access to a simplified version
of the completed drainage inspection, in the form of a series of checkboxes. This series
of checkboxes allowed the inspectors to identify any observed house-specific drainage
issues, and outline the appropriate methods for effecting repairs.         The benefits of
addressing the suggested repairs were also available in the brochure. In the case that a
resident was not available at the time of the inspector’s initial visit, an unmarked
brochure was left with comments requesting that the inspection be rescheduled at a more
convenient time. Notes were made on the official inspection sheet regarding visible
drainage issues only.


The “Break the Connection” brochure was designed as a resource to increase public
awareness by providing a straightforward explanation of the program’s objectives. It also
offered a simplified version of the inspection results to be easily utilized by the residents
to effect appropriate repairs. No specific references to City by-law #3913 were made in
the brochure.    The brochure’s diagrams were intended to help residents visualize
discussed drainage situations. Finally, the “Location of defects” feature was added to
assist in illustrating location-specific drainage issues. Flood proofing measures were also
included.


All collected data, including interview information and drainage descriptions, were
entered into a Microsoft Access Database. The use of a database and its query functions
allows the sorting of information by study area and scenario, and the identification of
relationships between individual datasets. The ability to access address- or situation-
specific information is also important when editing records and recalling the original filed
inspection sheet. This database can be linked to existing databases to supplement inflow
and infiltration studies, or be useful in creating maps to identify properties which have
experienced basement flooding.


The Downspout Inspection Program ran from June 2006 up to and including August
2006, at which point seasonal labour changes took place and there were no longer any
staff present to continue inspections. Initial inspections of the 642 houses/properties in
the Broadway Avenue area were completed, along with the initial inspections of the 914
houses/properties in the Clare Avenue area. Follow up inspections within both areas
continued until the end of August, at which point the Downspout Inspection Program was
concluded.


In the letter distributed prior to inspecting, residents were encouraged to complete repairs
to improve lot drainage. It was requested that all of the required and suggested repairs be
carried out voluntarily within a 30 day period following the inspection date as noted on
the brochure. Residents were also encouraged to contact the inspectors when repairs
were completed, however, no calls of this form were received. No follow up inspections
were performed and enforcement of by-law #3913 was not carried out.




Recommendations

To enhance the effectiveness of the Downspout Inspection Program and expand its
breadth of information collection, the following recommendations for further study have
been suggested.


   1) Data analysis should be done to determine whether or not there is a need for a
       new by-law to regulate the minimum length of downspout extensions away from
       the building foundation. It is likely that more repairs would be completed and
       reported if a by-law were in effect. Assessment of the proposed reduction in
       storm water flows to the sanitary system with implementation of such a by-law
       should take place.


   2) To improve residents’ responsiveness in rescheduling inspections, as well as
       effecting and reporting required and suggested repairs, it is recommended that the
       existing applicable by-laws (i.e. by-law #3913) be referred to specifically within
       the associated program literature. Please note that this action may also act to
       increase the volatility of inspector–resident relations. Compliance with the by-
   law would be increased by enhanced public awareness and interaction between
   City staff and residents or property owners.


3) A follow-up program should be implemented to obtain data from the properties
   which did not respond to the notice left regarding inspection rescheduling (i.e.
   those with building status other than “Interview/External Inspection”).     The
   residents who were informed to have improper drainage should also be re-
   inspected to verify whether or not repairs have been completed.


4) The use of smoke and/or dye tests should be implemented to verify drainage
   routes of buried yard drains without a visible outlet.
Results and Reports


The following double bar graph illustrates the individual totals for each “Status of
Building”, further distinguished by inspection area (i.e. Broadway and Clare Avenue).
The graphed data are broken down by headings outlined in detail on the Inspection Sheet
and associated definitions page (Appendix D).


The following pie charts show the variation of drainage scenarios that existed in both the
Broadway and Clare Avenue areas of the study. The charts are distinguishable by
inspection area, and are broken down further to relate drainage scenarios with specific
types of flooding that occurred on some of the inspected properties.


The following reports show the various drainage scenarios existing on properties of both
the Broadway and Clare Avenue areas individually. Also taken into consideration was
the correlation of these Drainage Scenarios with flooding history as reported through
interviews in each inspected area.
