Browse Forums Landscape & Garden Design 1 Jun 10, 2009 12:24 pm The plumber came by and had a look at my overflowing pipe in the backyard. Basically our stormwater was connected to an absorption pit which is long filled with roots and mud. The council will only allow 2 downpipes/100sqm worth of stormwater to be drained back to the stormwater pipes on the street. Considering an absorption pit and pump costs $2000/3000 I was thinking of buying a rainwater tank subsidised by the government to collect the stormwater. However, there is still a problem of overflow from the rainwater tank. The rainwater tank will be used to water a garden + lawn about 500sqm in total and planning to have it connected to the outdoor bathroom/sink. Not too keen on connecting it to the washing machine as it will be stormwater. I was hoping to place the rainwater tank under the deck. The questions I have are: 1. What drawbacks are there to having the stormwater connected to the rainwater tank? 2. How is it best to deal with the overflow - should I have it pump back onto the council street, just connect it to the broken absorption pit or rebuild the absorption pit - any other alternatives? 3. Can anyone suggest rainwater tank/s for under the deck - about 1.5m high? I am thinking between 2000 - 5000 litres. Thanks!

I have been singing those blanket type tanks which will be perfect beneath my deck. My main concern is that regardless of a rainwater tank I will still need an absorption pit and/or pump the overflow away? The plumber mentioned having a rainwater tank then having the overflow go to the current blocked absorption pit. If its raining so hard that the rainwater tank overflows then the area around the absorption pit pipe will be wet anway!
