Why Used Dishwasher Water is Considered Blackwater
04/09/25
“Why is used dishwasher water considered blackwater?”
People usually think of blackwater as fecal-contaminated wastewater. But this is only part of the definition. Blackwater also consists of any wastewater that contains heavy grease. Dishwasher water usually contains heavy grease. This is Why Used Dishwasher Water is Considered Blackwater.
Why Water Towers Don’t Require Electricity for Water Distribution
04/07/25
“Why don’t water towers require electricity for water distribution?”
Water towers hold water at elevated distances above ground. They can provide water to anything below using gravitational pressure. This means they don’t require electricity for pumps to provide water. This is Why Water Towers Don’t Require Electricity for Water Distribution.
Safe Yield Aquifer Discharge
04/05/25
“What is the point before aquifer discharge becomes unsafe?”
People extract water from aquifers. Taking too much water from aquifers can lead to land subsidence, dry wells, and long-term decline of water yields. The Safe Yield Aquifer Discharge measures the point where aquifer water extraction is sustainable.
Drainage Maintenance
04/04/25
“How do we maintain our drainage systems?”
Drainage systems are essential for keeping water out of places. But over time they become too clogged to properly work. Drainage Maintenance using cleaning, clutter removal, and infrastructure repair can help keep drainage systems alive and well.
Why People Should Not Build Wells Next to Roads
04/03/25
“Why should people not build new wells next to roads?”
New wells are built to accommodate water demand. For many infrastructure operators, building a well next to a road is tempting because repair vehicles can service the well more easily. However, this will expose the well to more runoff contamination, polluting the water supply. This is Why People Should Not Build Wells Next to Roads. Many places specify that people can only build wells after a minimum distance from roads.
Using Lakes for Ground Source Heat Pumps
04/02/25
“How can we use lakes for ground source heat pumps?”
Ground source heat pumps usually store heat deep in the Earth. But if a nearby lake meets the requirements for minimum volume, depth, and water quality, then it can also qualify as a storage material. This is how people can go about Using Lakes for Ground Source Heat Pumps.
How the US Clean Water Act Fines Direct Wastewater Discharges
04/01/25
“How does the US Clean Water Act fine people who direct discharge into waters and wetlands?”
The US Clean Water Act governs water sanitation in the US. If someone direct discharges wastewater into US waters and wetlands, they can get between 1 – 6 years of convictions and have to pay between $2,500 and upwards of $100,000 per day depending on the severity of the crime committed.
Water Hardness
03/27/25
“How do we measure how useful water is for cleaning?”
Water is used for cleaning all over the world. But if there is too much dissolved calcium and magnesium, then it becomes more difficult to use for cleaning. This is quantified by a variable called Water Hardness. Water hardness is measured by the density of calcium and magnesium in a sample.
The Health Effects of Manganese in Drinking Water
03/21/25
“What are the health effects of manganese in drinking water?”
Manganese in drinking water can come from a wide range of sources, whether its local industry or naturally occurring minerals. But no matter the case, having too much manganese in drinking water can lead to cognitive and motor skills problems. These are The Health Effects of Manganese in Drinking Water.
