Evaporation Credits, a part of Sewer Credit Programs, are designed to prevent overcharges for the amount of water not returned to the sanitary sewer system due to evaporation. Most commonly associated with cooling towers, municipalities providing Evaporation Credits (aka Deduct Meter Programs) can allow users to save a significant amount on their monthly water budget.
Sewer Credit Programs can also provide economic relief for other processes that consume municipal water, where water is not returned to the sanitary sewer. Examples include manufacturing facilities, food & beverage plants, laundries, etc.
Typically, participating municipalities design these programs for facilities that sewer <90 percent of their total domestic water intake. Evaporative cooling or manufacturing applications that consume water as a part of their process are prime candidates for this credit. For instance, cooling tower systems typically evaporate 65-80 percent of their make-up.
Depending on system size, annual savings can be several thousands of dollar per year.
For cooling towers, program requirements can vary. Most program administrators require water meters (make-up/bleed) to quantify water consumption. Other municipalities estimate cooling tower sewer discharge rates from total water consumption during non-cooling periods of the year. Regardless of your municipality's requirements, Precision Water can assist in securing your sewer credit. From equipment installation to annual meter calibration verification, we have you covered.
