After initial pilot projects ran last year, freshwater farm plans are expected to be ready for roll out from mid 2023 with a focus on the Waikato, Gisborne and Southland regions first. Freshwater farm plans are part of the government’s Essential Freshwater package and the aim...
DO YOU NEED CONSENT FOR YOUR CULVERT IN A RIVER OR STREAM? National Environmental Standards for Freshwater (NES-F) regulations now apply to a range of structures — including culverts — in New Zealand rivers, streams and connected areas. The regulations have been introduced because many of...
MAINTAINING NATURAL STREAM FLOWS IN INSTREAM STRUCTURES FOR GOOD FISH PASSAGE Fish passage guidelines look complex but this P&F Global white paper outlines the simple concepts you need to follow to design instream structures that comply with regulations. To design an instream structure that complies with regulatory...
HOW TO MANAGE STORMWATER DRAINAGE ON A SLOPE New Zealand’s landscape is dominated by hills, gullies and mountain ranges, which is why developing stormwater drainage solutions for sloping land is a common challenge. Land on an incline is easily eroded by heavy rainfall and fast-flowing stormwater, but...
EFFECTIVE FARM DRAINAGE SYSTEMS WILL REMOVE EXCESS SURFACE AND SUB-SURFACE WATER FROM PADDOCKS WITHIN 24-48 HOURS OF A RAINFALL EVENT Effective farm drainage and the rapid removal of surface flooding and excess sub-surface water helps to: prevent excessive soil water levels protect soil quality eliminate stock...
Understanding the impact of new freshwater regulations on farms and farm management Wetland protections and standards for intensive winter grazing are among the first of the new freshwater regulations to take effect. We’ve developed this short paper to provide an overview of all the freshwater regulations,...
A growing body of evidence is identifying plastic pipes as the sustainable choice for development — now and in the future. Plastic piping systems are strong, durable, light-weight and flexible, requiring significantly less energy to fabricate, transport and install than either the metal or concrete alternatives....
Dairy farmers have shown their commitment to improving water quality in New Zealand by meeting all the targets set out in the Sustainable Dairying: Water Accord to date, but more work lies ahead. Since the launch of the Water Accord in 2013, the dairy industry has...
Poorly designed instream structures (including culverts, weirs and dams) are a significant contributing factor in the declining populations of New Zealand’s native freshwater fish. According to DOC, about 70% of New Zealand’s native fish are threatened or at risk and the main factor in these declining...
Gravel, rocks, sharp stones and acidic effluent or chemicals can all contribute to the erosion and corrosion of your pipes. In scientific testing polyethylene piping has shown strong abrasion resistance, with considerably reduced wear rates compared to other materials. Pipe surfaces can be worn away over...
