Visit our house (and others) on the next Marrickville Council WSUD tour

Posted on

Marrickville Council has organised another Water Sustainability Urban Design (WSUD) tour in the local area, and we’re one of the stops.

The purpose of these tours is to show local residents some of the many ways of saving water. In our case, it’s our water tank, irrigation system, and permaculture garden sufficient to meet our vegetable needs.

To book, download the poster, ring Marrickville Council on 9335 2222, or email water@marrickville.nsw.gov.au.

See you on the day!

Water sustainable urban development: tour through Marrickville

Posted on

I spent an enjoyable morning today, visiting local houses who are saving water in interesting ways, as well as looking at some “rain gardens” in the street. (Our house was also the last stop on the tour, showing off what we’d done in the garden.)

The Water Sustainable Urban Development (WSUD) tour was organised by the “water revolution” staff at Marrickville Council. Not knowing what to expect, I was pleasantly surprised. It was hard to tell who were more passionate, the householders installing the water tanks, or the folks on the tour!

A few highlights:

The first stop was Graeme’s house in Marrickville. This showcases a significant project (8 months in length) to install a pair of 5,000L water tanks at the bottom of their large, and heavily sloping, garden. The tanks were then plumbed into the house, for absolutely everything other than drinking water. The cost was actually pretty reasonable, and the duration of the work was I think due to Graeme doing a lot of the work himself, presumably on weekends.

Something I hadn’t seen before was the pressure accumulator tank. About the size of a gas bottle, this holds water at pressure. This means that if a small amount of water is required in the house (washing hands, etc), the water is drawn from this holding tank, without the pump having to come on. This reduces the electricity required, and presumably helps to prolong the life of the pump. I’ll definitely have to look into this for our house.

The Hill Street rain garden was extremely interesting. This takes the normal storm water that runs of the street, and passes it through this mini wetland. The goal is not to store the water, but to filter it through the plants, which are grown on top of several layers of sub-surface material.

The end result is cleaner water going into the waterways, with a lot of the sediment, rubbish and nitrogen stripped out. I think it also makes for an interesting take on street-side gardens. Would love to see more of these go in throughout the Inner West.

John Caley, who ran the water course I attended some months back, had a house that certainly met expectations. Plenty of careful design of water tanks, and a nice use of water off next door’s roof (with their permission!). What took my fancy, however, was their lovely little communal garden in the small laneway beside the house. Plenty of produce to share amongst the neighbouring houses.

Mike and Jen’s house had everything that an inner-city greenie would want. Water tanks, careful management of water runoff, and chooks. Oh, and a nice vegetable garden squeezed into their small back garden.
