How Does Water Treatment Work in Mesa?

Water treatment

Water is a resource with a seemingly limitless supply in Mesa. You probably take your municipal water supply for granted, but you should know about the process which helps to clean and purify it before it flows from your tap. If you have a water softener or a water filter in your home, then the chances are you’re probably not drinking chemical-rich water. Having a clear picture of how Mesa water treatment takes place in your home helps you to stay healthy.

Arizona is one of the first states to use purified water using wastewater treatment plants. In 1926, Grand Canyon Village built the first wastewater treatment plant to reclaim water for beneficial use. Today, around 90% of the water used in Arizona is reused. Arizona’s wastewater treatment process undergoes multiple stages of water treatment stages. Water first enters the sewage treatment plants for primary treatment where larger floating objects are removed first. The activated sludge process in an aeration tank happens early in the early stages. Sludge treatment removes most of the organic waste to make it easier for the other stages of treating wastewater easier and more efficient. This is the primary treatment and the secondary treatment processes. Then we proceed to the rest of the process to discuss how most wastewater treatment plants work.

What Are The 4-Steps of Water Treatment in Mesa?

Water filters are a great way of removing chemicals, adding minerals, and removing impurities from your water – it is widely known soft water improves the cleanliness of clothes, reduces soap usage, and helps with skin itching. However, before your water flows to your home, wastewater flows to a sewage treatment plant first for treatment.

Coagulation and Flocculation

Coagulation and flocculation are the first steps in water treatment. It is the process of water treatment that targets suspended particles within the water which causes it to be discolored or cloudy. The first step is to coagulate or group contaminants into larger particle matter. The product or compounds are then agitated or stirred to help them bind together. Next, flocculation occurs when the now larger particles are allowed to settle out of the water by means of gravity.


Sedimentation is the second step of water treatment in Mesa. It involves pumping water through large tanks to allow larger particles to settle to the bottom of the tank. The water passes through the settling tank is then pumped into aeration ponds, where dissolved oxygen, ozone, or chlorine are added to kill any pathogenic bacteria that may still be present in the water. Once treated, water is stored in an underground reservoir within our system until needed by customers. Sedimentation also helps improve the taste and odor of the water by removing heavy metals like iron and manganese.


Filtration is the third step of water treatment in Mesa, AZ. Filtration, which occurs immediately after disinfection, removes impurities such as minerals and metals which may be present in the water. The average lifetime of a filter varies depending on your water source and the condition of the filter housing.


Disinfection is the last step of water treatment in Mesa. This involves temporarily raising the chlorine level in the water to kill harmful bacteria and other disease-causing organisms. The water dripping in your tap at Mesa has always gone through a process. Often the water treatment process is to make water safe for human consumption as well as doing other commercial activities. As we know, in Mesa, Arizona oftentimes our water is very hard and leaves a white film. That’s why many homeowners choose to install a POU filter device such as a water softener or reverse osmosis (RO) system. This gives you peace of mind knowing you are drinking clean water that goes above and beyond the normal water treatment done by the city. If you are in need, call us at P&L Plumbing in Mesa, AZ.
