Elements and Performance Criteria
- Determine design requirements
- Define pumping and power systems
- Select pumps to treat water efficiently and effectively as required and to enable supply at the flow and the pressure required to operate the distribution system
- Confirm that the pump motor combinations are efficient and the pumps are reliable, functional, serviceable and flexible for the intended application
- Calculate energy requirements and determine the layout of electricity lines and check with local authority
- Optimise the relationship between capital and operational costs including a comparison of energy sources
- Select structures, valves and accessories and integrate into a functional system that can be monitored and maintained
- Document performance indicators, design calculations and decisions
- Develop construction specifications that define the work required to make a suitable pumping and power system
- Check power supply design specification with power authorities
- Design an water treatment system
- Evaluate and design treatment systems with respect to a range of key variables
- Size pipes, valves and fittings according to design system specifications so that capital cost is balanced against operation costs over the anticipated system life
- Calculate and document flows, water levels and pressures to be within the acceptable tolerances for optimum performance
- Confirm that flows, water levels and pressures are achievable by the pumps operating at optimum efficiency
- Include mechanisms for controlling and adjusting pressure
- Determine capital expense budget
- Document design calculations and decisions and collate plans, specifications and manuals
- Organise a check of the design output by a competent designer
- Determine and document materials required from plans and specifications
- Estimate labour requirements based on documented work schedule, with reasonable allowance for variances in work schedules
- Confirm that costing attributed to each component is based upon quoted information from suppliers, or sound analysis of individual elements
- Determine operating expense budget
