DEWATERING & STORMWATER CONTROL
Effective water management is essential for maintaining compliance and minimising environmental impact on construction sites. Powerpac’s Dewatering & Stormwater Control range is designed to help you manage runoff, sediment, and water flow efficiently and responsibly.
Our Dewatering Bags & Discharge Filter Socks are ideal for filtering out sediment from pumped water, helping you maintain clean discharge points. Drain Guards work to trap debris and sediment at stormwater inlets, reducing the risk of blockages and water contamination. To manage flooding, stabilise soil, or redirect water flow, our Sandbags offer a reliable and flexible option for a wide range of site applications.
