Benefits of field trials

Not only were the users satisfied with the performance, but the local authority was also satisfied that this extensive field trial proved the performance of the system outside of the traditional scope of testing in research laboratories.

Such field trials are important in demonstrating system performance to water authorities, which are often reluctant to allow new technologies even though water is in short supply – the health of the community is always of paramount importance.
Hydraulic consultant Cliff Hensby, who assisted with the research, believes the local authority made a courageous decision to allow the trial to proceed in the interests of valuable research.

“The intent was to provide new information regarding the performance of drain line flow at such minimal gradients. If extreme installation conditions exist on a site the trials could then assist those involved in making the correct decision as to whether or not such an installation was prudent and in everyone’s interests. The grade is extreme and should not be viewed as the normal process and applied universally,” Hensby says.

“The essential benefit from the research has been confirmation of Dr Cummings’ contention that to achieve water conservation objectives the entire plumbing system should be of the highest standard and each element needs to be considered as part of a complete and balanced installation.

“Much of the information and benefits of the research are naturally introduced into Caroma’s manufacturing programs.

However, the broader industry also receives benefits as the lessons of the test program are fed back to the various relevant authorities and committees. Again, this is an example of a manufacturer working with the industry, and through those combined efforts, the entire community obtains real benefits.”
