Intake Cleaning Project Details

Intake cleaning of potable water transmission lines is generally warranted when there is a significantly large buildup of Aquatic growth, zebra mussels, tuberculation (rust) or other obstructions restricting required flows. Several available cleaning methods are used depending upon the type, material and location, of the structure to be cleaned. Hunt Underwater Specialties has utilized the mechanical wire brush method which involves using custom made wire brush attached to a cable that is winched through the intake line. The wire brush method is generally employed when other means are not possible. Another method for cleaning intake lines of long duration is the pigging method which involves using a series of low to high density foam pigs that are hydraulically pushed through the lines cleaning as they progress from one end to the other. High-pressure jetters are also used as well for this application as shown below.
