This is why the MwStop\u00ae Bypass solution?<\/h3>\n<\/div>\n
\n

Sewer systems and receiving water bodies can become overloaded during heavy rainfall,
\nstorm surges and high water levels. If the drainage system cannot accommodate the water, water may be forced back towards the building.<\/p>\n<\/div>\n

    \n
    \n
    \n

    A hybrid bypass shaft combines a backwater valve and a pumping station in one energy-efficient solution. During normal operation, rainwater and wastewater are discharged by gravity. In the event of backflow, the backwater valve closes and the pumps divert the water around the closed valve.<\/p>\n<\/div>\n
