Cobaki Lakes

development

Planit was engaged by Northern Water Solutions to undertake the water, recycled water and pressure sewer servicing infrastructure assessment and design for a proposed private water utility for a 5,500 lot residential development.

A detailed assessment of the water and sewer servicing strategy was required for the entire development to support the application through IPART for the creation of a private water utility to service the development.

The works required included preparation of concept feasibility assessment, preparation of a water balance report for the entire development, servicing masterplans for water, recycled water and sewerage, and design of a wastewater treatment plant to produce Class A+ recycled water for reuse within the development.

Hydraulic and net present value assessments were prepared to compare the proposed water and recycled water supply systems between a gravity fed and booster pump supply system.

Hydraulic design of a pressure sewer system was required for the entire development as traditional gravity sewer was not viable due to high groundwater and environmental constraints.
