Earlier this week I went to talk about this project to Dominique Hes who gave me some useful feedback, which included pointing me in a new direction in terms of treating and reusing waste.In earlier plans I had drawn a distributed system of blackwater treatment facilities, but Dominque pointed out that maintenance of several small scale plants would be a major problem, and I mean, you really don’t want your blackwater treatment system to go wrong!
For some more ideas Dominique referred me to a project called EVA Lanxmeer in the Netherlands which she has used as a case study in her recent paper: “Opportunities for Semi-Decentralised Water Reuse and Power Production in High Density Areas.”
EVA Lanxmeer is a small community in Culemborg. In some ways it’s comparable in size to our neighbourhood; there's about 250 homes with a small commercial/education area.
Their proposed treatment centre will treat the neighbourhood effluent, green household waste and some garden waste. The treatment process produces garden compost; clean water that can be used for anything except drinking water; and bio-gas that can be used for energy production and heating.
It is designed to not produce dust, odour or noise. And it’s estimated that the system as a whole will save 194 kg/home/yr of CO2 emissions. Not bad.

This system is not completely detached from existing infrastructure for waste treatment, water and energy – it’s not completely self sufficient, but it promises a workable balance between localised management and production and the inefficient centralised systems we use now.This plant needs a sizeable space, but we do have the room to do this in our neighbourhood! The warehouse on the corner of Wellington and Hotham is currently vacant; developers were trying to turn it into apartments but the proposal appears to have either failed to make it through VCAT (our system for dealing with planning/development conflicts), or lost momentum in some other way.
The warehouse has a large floor area and is located in our proposed neighbourhood activity centre. It would be a great site for a environmentally sustainable six star (or equivalent) mixed use development. And this development could house our community black water treatment plant in its basement. Perfect.
