Modular treatment solution efficiencies for Hastings District Council

Ryan Hunt (Filtec Ltd) , Steve Cave (Hastings District Council)

Containerised, skid-mounted, and modularised water treatment plants are a cost effective and Drinking Water Standard New Zealand (DWSNZ) compliant solution for existing plant upgrades or new sites, particularly when applied to small to medium sized flowrates.

This paper discusses how Filtec and Hastings District Council (HDC) have worked together in a progressive work model to upgrade six of their small community water treatment plants to ensure safe compliant water is supplied to communities in Hastings. The paper also discusses Filtec’s use of a modular approach to create six similar but fit for purpose water treatment plants to suit each site’s specific requirements. Furthermore, how Filtec and Hastings District Council collaborated and applied the lessons learned and efficiencies gained as the project progressed from site to site.

With new regulations, many councils and communities will be required to upgrade their current treatment plants, many of which will require similar upgrades. A standardised modular skid-mounted plant can be an effective and fully compliant solution. Standardised pieces of equipment enable lower cost operations, servicing, reduced storage of critical spares, and deployment efficiencies over multiple sites.

Removing the need for bespoke designs by standardising equipment, processes, delivery, and deployment reduces the required engineering/design time, construction and overall project length reducing the capital cost.

Also covered in this paper are the limitations and potential issues that could arise by using standardised modular or containerised or skid-mounted plant and equipment, and how these limitations can be avoided.
