Good management of stormwater runoff from worksites is important to prevent contamination of waterways or groundwater. This page discusses stormwater runoff from industrial or trade sites. See the earthworks page for information on the stormwater management requirements for development or building sites. Best practice Plan your site carefully.
Construct drains or slope your site so that rainfall runoff doesn’t cross your working areas. This keeps uncontaminated water separate from waste water,

Monthly rainfall norms at monitored Taranaki sites.
Taranaki’s temperature trends. Sunshine hours and wind speeds in North Taranaki have increased, while winter rainfall has decreased and severe weather events have become fewer and less intense. South Taranaki has seen an increase in spring rainfall. The Committee was told that the Resource Management Act explicitly excludes the Council from climate change regulation, but future likely consequences, particularly for rainfall, are being factored into plans and projects, most notably the recent upgrades to

Policy Analyst Denise Young said projected changes in Taranaki include a slight temperature increase of between 0.7 and 3.1 degrees warmer by 2090, along with a rainfall increase of 5-9%. There is also increased risk of erosion, landslides, droughts, severe flooding, invasive pests and weeds, sub-tropical diseases and changed ecosystem composition. “In
