CEMP Waste Management section

[flanagaj]

So I am using ChatGpt to try and come up with a CEMP plan.  One of the things that I am struggling to get my head around, is the handling of waste water that is generated from washing out mixers, tools, paint rollers ...our site is off mains drainage and any waste water is either discharged to the ground or when installed, to our sewage treatment plant.   There is also a redundant septic tank on the site, which could be used and periodically pumped out.   I am maybe overthinking what is required in the report, or what regulations I need to comply with.

Anyone had to do one of these reports who was off mains drainage and can maybe provide some advice?

Have you been specifically asked to provide one?

Yes

Maybe I just need to specify that wash out water will be captured in a bund and allowed to settle, before the water is reused for concrete or other washing activities.  The sediment will then been disposed of using a certified waste disposal company.

There is a specific product for this, it is a plastic tank you wash out into, the water seeps through a cloth screen and leaves the sediment behind, you then add the sediment to the hardcore pile. 
 

look it up, I’m not saying buy one, just look the name up and add it to your cemp.

Absolute bargain.  Not!

It's a good thing to do, even informally. 

Washout from cement  mixing can be thrown  onto your hardcore or sand pile.

Emulsion paintbrush rinsing I think will break down in a soakaway....I don't know that though.

Gloss paint?   Put the resulting spirits in a plastic bottle; thence to tip.

( I'm trying to use semicolons where applicable or they will die).

Other liquids could go in a settling tank/barrel. Some will neutralise each other. Some will bubble away or be eaten by bugs. The resulting sludge can go in a skip or be bottled to your recycling tip.

 

Now write that up to sound technical.

For your own benefit have a waste reduction strategy. 

How many skips? Now half that and find a means of ensuring it.

Cardboard flattened and bundled....and not in skip.

Timber cutting strategy to reduce waste from 10% to 2%. Ditto boards.

 

No bricks or blocks or pallets in there.

 

No air gaps obv. If the lorry can hardly lift it,  well done.

 

Other suggestions?

 

As a business we planned on 4 skips per £1M job cost.  Equals about 1 skip per £100,000 materials. It's worth a lot of money.
