Water Quality in Rainwater Tanks – Microbiology

Water Quality in Rainwater Tanks – Microbiology

Longitudinal sampling from rainwater tanks throughout Australia was employed to analyse the microbial ecosystems in water supplies. Epidemiological research indicates that drinking rainwater does not create averse health impacts. The concept that domestic rainwater storage tanks may host sustainable microbial ecosystems that improve water quality has not previously been addressed. The bacterial diversity, cultivated from more than 80 samples from 22 tanks at various locations across eastern Australia, is presented as evidence of potential operation of a functional micro-ecology within rainwater storage systems. In combination with low abundance of bacteria associated with faecal contamination, the results indicate high quality water and beneficial ecosystem processes. A recent presentation to the RHAA on water quality processes in rainwater harvesting systems is also provided.

The water sensitive urban design (WSUD) development includes a unique stormwater treatment train that includes rainwater tanks, protection of old river red gums in multiple purpose rain gardens, bio-retention swales and restored waterways.

Review of the Hill End Water and Sewerage Scheme

The township of Hill End was established during the 1880s due to the discovery of gold in the area and in 1967 part of the town known as the historical village of Hill End was proclaimed as a historical site. Hillend is located about 70 km northwest of Bathurst and 69 km south of Mudgee.

Is zero afflux the question or answer to better flooding outcomes?

Presentation by Peter J Coombes and Andrew Allan at HWRS 2022: Is zero afflux the real challenge or solution for better flood management? It is vitally important to establish science and legally based rules for fair administration of the objectives and exploration of options that respond to flood risks. Otherwise, there will be a substantial administrative burden for marginal benefit. Our professionals and agencies need to be prepared for a different and challenging future, and our methods need to be fit for purpose from a whole of society perspective.

Systems Analysis of Water and Sewage Services, Costs and Prices

Systems Analysis of Water and Sewage Services, Costs and Prices

Bottom up systems analysis of urban water resources and market mechanisms for pricing water and sewage services
Presentation Peter J Coombes, Michael Barry and Michael Smit at the HWRS 2018 conference in Melbourne at 11:00 am on Tuesday 3 December 2018. Consumers in the Greater Melbourne region pay uniform fixed and variable tariffs for utility water and sewage services. Removing fixed tariffs creates substantial reductions in water demands and improvements in water security to 2050 at a net present value of $8.6 billion. A full usage tariff regime was seen to increase water efficient behaviours and reveals improvements in household welfare.

Direct Rain Investigation and Urban Stormwater Design

Direct Rain Investigation and Urban Stormwater Design

Presentation by Peter Coombes, Mark Colegate and Sophia Buchanan at Stormwater 2018 conference at 3:45 pm on Wednesday 10 October 2018. Urban stormwater catchments can be subject to complex hydrological and hydraulic responses that are driven by unresolved sub-catchment influences, flow pathways and local depression storages. This paper provides an overview of the processes to define complex urban hydrology, establish evidence based targets for urban catchments and design of detention basins using ARR2016 resources.
