As Local Authorities and private businesses are being asked for ‘Financial Prudence’, and to save money whilst still delivering services, more emphasis will be on better integrating and optimising internal procurement systems with the external service delivery providers.
This paper outlines a contractor’s view on the entire contract procurement process. It aims to provide an insight to asset owners on the processes and systems that contractors believe will deliver them the best outcome for their service delivery needs.
Biological phosphorus removal was studied in two full-scale waste stabilisation ponds (WSP). Luxury uptake by microalgae was confirmed to occur and in one pond the biomass contained almost four times the phosphorus required by microalgae for normal metabolism.
Coal seam gas (CSG) waters are a by-product of natural gas extraction from underground coal seams. The main issue with these waters is their elevated sodium content, which in conjunction with their low calcium and magnesium concentrations can generate soil infiltration problems in the long run, as well as short term toxicity effects in plants due to the sodium ion itself.
The influence of CO2 addition to high rate algal ponds (HRAPs) on nitrogen removal was investigated using two pilot-scale HRAPs operated with different hydraulic retention times (4 and 8 days).
Nitrogen limitation within biological wastewater treatment processes is a cause for concern in a number of large-scale industrial sectors. Microbial fuel cells (MFC) are an innovative technology with potential application within the wastewater treatment industry.
This paper presents the key elements of this programme, discusses progress made to date, and presents findings from an initial assessment of options for addressing stormwater drainage issues. The programme which is described in this paper can be adapted to other utilities as part of an effective programme to manage stormwater.
A study to identify best international and local practice for integrated coastal and catchment planning and management (ICCM) was undertaken for the Auckland Regional Council (ARC).
Lincoln Township (population of 2,700), a rural community within Selwyn District has been identified as an area of significant growth in the Greater Christchurch Urban Development Strategy, with population predicted to increase to 10,000 by 2041.
Auckland faces major stormwater drainage issues including flooding, growth pressures and ageing infrastructure. Historically, stormwater management within the Auckland City isthmus has been undertaken on a catchment-by-catchment basis.
This paper describes the logic model based framework to enable ongoing assessment of progress on the ICMP workstream.
This paper will consider the process followed for the development of the Pokeno Stormwater Catchment Management Plan. Some of the pitfalls discovered through the process, how they were overcome and how things might be done differently next time.
