On average , an entrepreneur in mobile pressure washing will generate more than 500 gallons of wastewater each wash day . As you can see the potential to contaminate water resources of our country is enormous. As professionals and concerned citizens is our responsibility to do everything we can to preserve our natural resources. To this end , I propose the following for your consideration.
pH (p c ) a chemical symbol.
A measure of the acidity or alkalinity of a solution numerically equal to 7 for neutral solutions , increasing with increasing alkalinity and decrease with increasing acidity. The pH scale commonly used varies from 0 to 14 .

People in the industry of mobile power wash using a test kit for measuring the pH of alkalinity or acidity of the wastewater. To do this, before discharging the water to a sanitary sewer system where it is permitted . If water is not removed within the limits set by the authorities to end by addition of acid at high pH or low pH soda wastewater was captured for proper disposal . The pH test kit is used more in a small roll of red litmus paper and a color scale / number . To test the solution in question is torn by a small strip of litmus paper and dip a piece of the solution. The use of the color scale / number provided with the kit color of litmus paper report that has been dipped in the test solution to the color scale / number and color / number match is the value of pH of the solution .
Impact on the environment:
A pH range of 6.0 to 9.0 appears to offer protection to the life of freshwater fish and invertebrates housing fund
The most significant impact of the environmental pH of the resulting synergistic effects . Synergy is to combine two or more substances that produce effects greater than the sum .
Synergy has special meaning when considering the water and wastewater treatment . The steps involved in the treatment of water and wastewater require specific levels of pH . In coagulation [ a method of treatment ] occur, the pH and alkalinity should be within a limited range .
Types of Gutters
Before downloading any sewer wastewater should check with local authorities to determine the extent of their needs.

There are basically three types of culverts are : health , Storm, and combined . Most cities have a toilet and a storm sewer system. The sanitary sewer system is what your house is connected to the sewerage network. This piping system goes to the treatment plant wastewater or public water Treatment Works ( POTW ) . In the POTW of wastewater is treated and discharged into lakes , rivers or streams. This is the origin of the wash water must undergo treatment before being discharged into lakes, rivers and streams.
The storm sewer is where rain water in channels along the streets and roads. This water is generally discharged directly into lakes , rivers and streams without treatment. Because this water is not corrected before release into the environment should not be discharged washwater to a storm drain .
Some cities have a combined sewer system where sanitary and storm sewers are all water systems and wastewater and storm it comes to the treatment plant . In these areas, wash water can be downloaded to the storm sewer . You will need to call the sewer service in every area in which you wash , to determine which system is evacuated to .
Most outside drains are storm sewers and sewage drainage innermost sewers are , but not always. Make sure you know which is which . If your client does not know call the Department of Sanitation you're hooked on them and will come out and determine the sewer system is connected to each drain . In many areas of this service is free .
The ability and capacity of municipal wastewater vary considerably and so do their download limit . Discharge limits are determined by many factors including: the size of the body of water discharge , such as a lake, river , stream or the ocean, they are , and how much you download. The larger masses are more relaxed limits water discharge. Due to limitations and download capabilities vary IPE treatment , the amount of wash water requires treatment before being discharged into the sanitary sewer may also vary from IPE IPE .
Elimination of water to wash the storm sewer
Normally, you should never remove the water to a storm drain . However, there are exceptions to this common rule . They are : home washing a house by owner , car wash in homes, and washing cars for charity. Municipalities generally high these transgressions.
Some cities allow a wash in cold water without chemicals ( other cities wash with warm water and chemicals where there is no oil, grease , dirt only ) to enter the storm sewer if these areas do not contain hydrocarbons , pesticides, insecticides and antifreeze. Washing with hot water is considered that the water treatment of the oil with hot water and emulsified fats . Wash in cold water is considered no worse than rain event . Oil and grease stains should be cleaned with absorbent clay ( kitty litter ) and thrown in the trash. Leaves, debris and dirt should be cleaned before washing if this contamination does not enter the storm sewer . Inputs of storm sewer must be examined to catch leaves and debris and wash water must pass through a boom or oil absorbent pad to absorb oil . No traces of hydrocarbons must be present after passing through the filter absorbing oil. The absence of chemicals can be compensated by using a rotating nozzle such as a zero degree nozzle or Turbo Rotomax zero degree rotation of the nozzle . Typical examples are washing Vehicles in batches ( powder dealer only) , sidewalks , malls , parking lots, buildings and homes.
Some cities allow the construction of washing with acid cleaners if the acid is neutralized before entering the storm sewer . Typical neutralization with sodium bicarbonate ( baking soda ) , sodium carbonate ( soda ash ) or an alkali instead of rinsing with clear water detergent. In other cities the cleanup with cold water, no chemicals, and rotating nozzles freezing.
