There is no regular price for any of the above systems as each method is individually designed according to site and soil characteristics and the ultimate needs of the client. As a guide, the cost of options 1-3 is comparable to a complete AWTS installation (often cheaper). Developments requiring the more advanced systems are priced according site-specific engineering, access and design evaluation.

The capital cost should be compared with lifecycle costs of conventional methods and the potential to value add with future improvements that may not otherwise be possible.
