Infiltration & Inflow


WKUD has established a dedicated I/I (infiltration/inflow) crew to reduce infiltration and inflow. Although it is unreasonable to expect 100% removal of I/I, experience has shown that possibly up to about 30% of infiltration can be cost effectively removed. However, up to 60% of the inflow can be removed in some cases.

WKUD has installed flow monitoring equipment at key manholes located throughout the collection system.  Smoke testing is performed where applicable during dry  months. 

WKUD has purchased state-of-the-art video equipment to assist in the visual Inspection of the collection system.  WKUD performs manhole inspections that coincide with the line televising. Once defects are identified repairs are made by WKUD crews or are contracted out.

In the last two years WKUD has greatly escalated its work in the 10 Mile Creek drainage basin and in the Karns area. The cost of the rehabilitation is over $6M with another $6M dedicated to work in the very near future. WKUD takes its responsibility very seriously and is dedicated to the removal of I/I.
