Heavy duty PVC basins such as the ones below cost around $200 each. We are manufacturing our own using extra pipe we have around the shop for $50 each. These more durable replacements will be able to withstand the weight of a 4-ton tractor much better that the residential plastic drains above.
You may also notice the new rock around some basins in native areas. This is done in an effort to keep debris from blocking the drains during heavy rains. Now is a great time to take care of these housekeeping issues ahead of the summer rains.
