pond venting
Pond Lining Sytems now recommends to all customers that they VENT all lined effluent ponds.
- Your dairy effluent pond is a very important and valuable asset and you as the farmer cannot cut corners or it may come back to haunt you.
- Installing venting is a very cheap insurance policy.
- We recommend using the Wavin system which is world renowned and which we can arrange for you through. Contact us for more info.
How does Venting work?
Underground gases (mainly air, methane and carbon dioxide) can be blocked on their way up by the pond linings. These gases originate from the decomposition of organic matter or following the rise in the water table. Drainage under the lining, as well as a blow off device, is then needed to remove the gases. Our Solpac device is specifically designed to allow the blow off of gases drained under geomembrane liners, by preventing penetration of meteoric water and any intrusion of small animals. There is one type of vent per type of geomembrane.
