Manufacturers of sustainable Drainage and Sewer cleansing systems utilising the flow within the pipe to more effectively clean and keep clean entire catchments. Optimising efficiency, reducing costs and enhancing the environment by reducing surface and property flooding and contamination of rivers and watercourses. Flusher2 also provides significant benefits reducing the buildup of Fats Oils and Greases (FOG). These low cost and easy to retrofit systems will enhance any underperforming drainage system increasing hydraulic performance without causing the damage to above and below ground infrastructure that occurs as a result of using existing high pressure water jetting solutions. Flusher2 can also be used as an invaluable aid to everyday activities such as CCTV Surveys and a wide range of remedial works operations creating "Dry-Pipe Conditions", optimising plant and equipment safety, the risks associated with stranded or lost equipment resulting in blockages and resultant flooding. They enhance opportunities for over-pumping facilitating safe unattended reservoirs for pumping to be established, with in built overflow facilities that protect the environment in the event of pump failure. Flusher2 uniquely can be inserted in minutes, can be repositioned just as quickly allowing its position to be optimised, and also allowing it to be used for temporary purposes such as emergency flood protection, blockage clearance, for optimising FOG or H2S dosing operations and for pre cleansing or programmed cleansing operations making this the most flexible and sustainable solution currently available. Flusher2 unlike alternatives has the potential to extend the operational life of any drain or sewer asset and in doing so reduce OPEX and CAPEX costs significantly. Under normal conditions it is reasonable to anticipate devices to last a minimum of 5 years without replacement and any need for maintenance is minimal.
