Our previous blogs explored the importance of effective concrete washout management in preventing environmental damage. Today, we take a closer look at the environmental impact of concrete washout and why PumperDump is the responsible choice for construction projects.
Concrete is one of the most widely used materials in construction worldwide. It is also one of the most commonly produced materials on the planet, with demand continuing to grow as populations increase and cities expand.
While the prevalence of concrete is well known, the environmental risks associated with its waste are often overlooked.
Is Concrete Washout Really That Harmful?
It’s reasonable to question whether concerns around concrete washout are justified. After all, concrete structures are everywhere, and once hardened, they appear harmless.
Some may even wonder whether the NSW Environment Protection Authority (EPA) is being overly cautious.
The short answer: no.
Concrete washout is genuinely harmful to the environment.
Before concrete hardens, the mixture — and the water used to clean tools and trucks — is highly corrosive. This slurry contains materials such as grout, plaster, cement, mortar, stucco, and other compounds with harmful chemical properties.
Why Concrete Washout Is Dangerous
The real danger arises when these substances leak into local waterways and soil systems.
Concrete washout water has:
- A toxicity level greater than ammonia
- A pH level close to chlorine bleach
These characteristics make it extremely damaging to ecosystems if not properly contained.
This is why PumperDump places such a strong emphasis on preventing concrete washout from entering local water systems.
What Can Be Done About Concrete Washout?
At this point, it’s clear that concrete washout poses a serious environmental risk. The regulations and precautions enforced by the NSW EPA are not overreactions — they are necessary safeguards.
So what are the options?
Historically, washout pits and washout bags were commonly used. However, these methods are now outdated and pose significant environmental and financial risks.
We do not recommend these systems.
Using inefficient washout solutions can result in:
- Contamination of lakes and swimming areas with zinc and iron, which are linked to diabetes, cancer, skin irritation, and other adverse health effects
- Exposure of freshwater systems to corrosive concrete slurry, damaging aquatic ecosystems
- Infiltration of calcium, magnesium oxide, and other concrete ingredients into soil systems
