Problem: The construction and movement joints were leaking raw sewage to ground. Previous repairs were failing and only channeling the sewage in to the drains. The environment agency were threatening the customer with prosecution if the problem wasn't resolved. The lane is critical to the treatment process and could not be out of action for any length of time.
