NEW POND LINER COMES WITH 20-YEAR GUARANTEE WHEN CANTERBURY DAIRY farmers Nigel and Amy Rutherford of Malbon Dairy Farm chose to upgrade their clay-lined effluent storage pond, they chose Viking Containment to provide advice and the right product. Increased storage capacity and compliance were the key drivers for the pond design, and it also provided a contingency for possible future expansion. The previous storage was only 4-5 days, but their new High Density Polyethylene (HDPE)-lined pond has increased their capacity to 1800m³, providing 20-25 days storage.
The new effluent system lined by Viking Containment.
Nigel is very happy with the outcome. “In some recent wet weather where the soil capacity was at its maximum, I didn’t have to worry about effluent management issues – it makes the whole operation very efficient and much easier,” he says. The extra storage capacity allows them to put more time and focus into animal health and pasture. The new pond construction involved removal of the existing pond so it was programmed to be completed in the offseason. Earthworks were completed by Roy Hill Construction to a high standard. The excavated pond was 40m x 40m x
3.5m depth with a 2H:1V slope gradient and a 500mm freeboard. The liner system consisted of 1.5mm HDPE Liner, Geotextile protection layer over the subgrade surface, Viking Gas Venting system and Geoladders for safe egress in and out of the pond. The 1.5mm HDPE liner comes in 8.0m wide panels which allows efficient deployment and installation, and was completed in one day. All the seam welding and testing was documented in a comprehensive Quality Assurance Report. For peace of mind and assurance Viking’s HDPE liner also has a 20-year product warranty.

PPP INDUSTRIES LTD INSTALLED THE FIRST PRESSscrew separator at a New Zealand dairy farm in Northland in 2001. This was quickly followed by another unit in Manawatu. Since 2001 PPP has installed systems in most provinces of NZ, but the range of customers is now expanded to include piggeries, truck wash stations and meat works. The design and installation are an important part of all its projects but the quality of the separators ensures PPP has never experienced a failure. PPP offers three models catering in size from flow rates of 5-10m3 per hour up to large projects of 80m3 per hour. The separators can deal with heavy flows of solids such as paunch material through to diluted waste such as in the dairy industry. Since the company’s involvement in business waste streams other opportunities have developed such as composting. Its supplier of separators also manufactures “in-vessel composters” so smells can all be contained. These systems have minimal power and labour demand so are very efficient. These composters are part of the success that enable our systems to turn protein waste, such as dead birds from the poultry industry into a biological fertiliser in 24-30 hours. PPP Industries Ltd was established in 1962. Since the inception of the business the company has been a leader within the poultry industry, dairy feeding systems, sheep dipping equipment and now has laid out plans to revolutionise the composting industry.
