This explainer was first published on August 6, 2022. “Although these walls may have existed for a long period of time, this can be more good luck than good design.” Many existing walls are not doing much to support the slopes even though they’ve lasted for years, said Williams. Many retaining walls built years ago are rotting away or structurally unsound.

The signs could be a smooth lawn becoming bumpy, new cracks appearing in surfaces, soft or wet ground, leaning trees or walls, exposed foundations and changes to the house like sticking windows and doors. Williams recommends that people keep an eye out for new features which could signal unstable land. Stormwater pipes are particularly important to maintain because they keep moisture away from the soil, he said. People should check pipes for leaks – Kupec said any leaking pipe, whether sewerage, drinking water, or stormwater, increases the moisture content of the soil and makes land more likely to slip. But slips are an expensive problem once they happen. “Most people don’t think about it until they have a slip,” said Massey.

You can’t always prevent slips but you can lower the risk. (File photo) Can residents prevent slips? We’re also exposed to “a number of different weather patterns” meaning we can have a lot of rainfall in a short period of time.Ībseilers working along the southbound side of Ngāūranga Gorge securing the cliff face from slips and rock falls. The bedrock in Wellington is “highly fractured”, said Williams, making it more prone to breaking apart and sliding away. He said slips are a natural process on these steep slopes, but human interference gets in the way. Over a century ago, before modern engineering standards existed, we built a lot of houses on hills by excavating the side of the hill into flat platforms and dumping the excavated land into valleys.Ĭompared to somewhere like Christchurch, Kupec said Wellington experiences more slips because of these “modified slopes” which make the land “simply not stable”. Why are slips common in Wellington?īasically, Wellington is a hilly city with prolonged rainy periods in winter. The Water Reclamation division performs sewer effluent pretreatment services. Based in Covington, Ga., the authority functions under a number of departments, including Water Reclamation, Engineering and Water/Sewer Maintenance. Once the land starts to slip, it moves down a slope until it comes to rest on a flat surface. Established in 1970, The Newton County Water & Sewerage Authority is a part of the state legislature. Long periods of moisture make the bedrock underneath the soil weaker, Williams said. That high water content could be because of a leaking pipe, consistent rainfall, or a damp location. “Ground with already-high water content means you don’t need as much rain for a landslip,” said Massey.
