- The higher initial investment in clay pipes might be offset by the long-term cost-effectiveness, thus positively influencing the resale value.
Environmental Impact of Clay Pipes
The environmental impact of clay drainage pipes presents another critical aspect to consider when assessing their suitability for use in New Zealand.
Clay pipes, being naturally occurring materials, have a lesser environmental footprint than their plastic or metal counterparts. Their high axial and crushing strength mean that they last longer, reducing the frequency of replacements and the associated environmental costs.
The smooth wall surface of clay drainage pipes not only minimises frictional resistance, enhancing efficiency, but also reduces the energy required for pumping, subsequently lowering carbon emissions. Unlike other materials, clay pipes are resistant to aggressive environments, including chemicals and corrosive substances. This resistance reduces the likelihood of leaks and contamination, safeguarding New Zealand’s groundwater and soil health.
Moreover, clay pipes are ideal for wastewater management in food processing plants and brewery facilities, industries that New Zealand is globally recognised for. By effectively handling waste, these pipes contribute to preserving the country’s pristine environment.
