we’re able to make predictions about the water quality at any given location based on a range of environmental characteristics that are common to those catchments where monitoring data is available. These characteristics include the geology, land cover, elevation, rainfall and the number of farmed animals. To refine these models and improve our understanding of the actions we can take, we need to assess whether contaminants are the result of human activities or
organic material such as poultry waste. This is then composted in one very large pile which is turned to stimulate the composting process in the initial phase. Any rainfall runoff and leachate that is generated, drains into a series of ponds for treatment referred to as the pond treatment system (PTS). Between each pond is a baffle that skims off any floating hydrocarbons as the leachate passes through. These ponds also treat the leachate and stormwater from pad 1 where greenwaste and sheep …

The Haehanga enters the Mimitangiatua about 780 m downstream of the site office and about 100 m downstream of SH3/Mokau Road. 35. A key feature of the existing site is the drainage that has been put in place to ensure clean water running off the hills in rainfall events is diverted around the active site areas. 36.

rainfall events, or if animals have direct access to waterways. Human faecal contamination of waterways can occur via poorly treated sewage or septic tank systems, or during heavy rain when sewerage systems cannot cope and they overflow into stormwater systems. Because of these heightened health risks from runoff and stormwater, people are often advised to avoid swimming for 48 hours after prolonged or heavy rain. There are two distinct components to assessing the suitability of a site for

Relatively high rainfall up on the mountain quickly drains through these river systems, contributing to high water flows and the swift clearance of excessive
the tributary (WIT000460) exceeded the historical maximum count for that site. High counts such as these are typically associated with heavy rainfall and the resultant increase in agricultural runoff. However, the lack of precipitation prior to sampling page 14 indicates that rainfall was not a significant factor in these results. As the counts were high at sampling sites upstream of the septic tank and sewage pump station it is unlikely that these results would be due
effects. Ring drains and bunds were clear and fit for purpose. Everything was satisfactory. 23 May 2013 Inspection was undertaken following significant rainfall in previous days. The skimmer pit contained discoloured water as a result of run-off from construction activities at the site. There were no visual effects from this discharge on the receiving waters. The ring drain near the generation unit had a section of damaged plastic liner. The newly constructed ring drain on the eastern boundary
irrigation areas were found to be working well, however during the September inspection it was noted that care needed to be taken when irrigating after rainfall as this increases the likelihood of ponding. 2.1.2 Results of abstraction and discharge monitoring 2.1.2.1 Waingongoro River abstraction Process and operation water for the site is pumped from the Waingongoro River, which is located 7.2 km east from the Company site (Figure 1).
