                                          4.0 Key Features And Benefits
                                          The Ecosol™ Litter Basket captures and retains a range of pollutants at entry points
                                          to the drainage network. Easily installed into most types of side entry pits, also
                                          known as gully pits or catch-pits, it retains more than 97% of pollutants greater than
                                          600µm and in the field it has been found to collect much smaller particles, including
                                          fine sediments.

                                          For many years the Ecosol™ Litter Basket has been seen as the industry standard
                                          for at-source filtration with its effectiveness proven over time both in the field and
                                          under strict laboratory conditions. Consisting of a capture basket, reusable liner,
                                          and overflow bypass flap(s) the Ecosol™ Litter Basket is fitted below the invert of
                                          the gutter inside the drainage pit and, importantly, does not obstruct flow into the
                                          outlet pipe. The liner is easily removed and emptied during maintenance and
                                          comes in a range of filtration fabric sizes from 100µm to 3000µm, depending on the
                                          site requirements.


Key Features                      Benefits

                                  • Minimal head/hydraulic loss
