Cycles of Concentration Analysis: Evaporation remains constant regardless of water usage. Therefore, effectively managing your Cycles of Concentration (COC) will save you water and money.Simply compare your current cycles to the respective number of cycles to determine estimates savings (negative numbers) by increasing the number of cycles,or determine the estimate cost (positive numbers) by decreasing the number of cycles.

Overflow & Leak Analysis:The severity of an overflow or leak determines the amount of water and money being wasted. The severity is contingent upon many factors, including the size of the cooling tower, the size of the make-up and blow-down pipes, the size of the float valve, as well as the length of time the overleak or leak goes undetected. As a result,it is difficult to accurately predict the cost (both in terms of wasted water and money) of a future upset. All cooling tower upsets are wasteful. Early detection goes a longway to saving you water and money. The following analysis accounts for the annual make-up water usage, and assumes an upset is a percentage of that total usage. Eachpercentage increment takes in account the percentage of annual make-up water usage, and multiplies it by the total cost of water (water + sewer) to estimate to potentialcost of an upset. A national survey of cooling towers determined that 40% of cooling towers incur some type of upset in a given month. An upset is defined as an overflow,leak, or when the COC get thrown out of balance.

Hereʼs is the COMPREHENSIVE Cooling Tower Monitoring proposal. This is used when adequate cooling tower information is provided. It is when the prospective client is located in an area that doesnʼt have a viable evaporation credit program offered through the water utility. And it is used in combination with the ECS Cash Flow Analysis when the prospective client is located in an area with a viable program.

Hereʼs is the Cash Flow Analysis, which is used for clients to decide which ECS program to enter. In this instance, the client enrolls directly in the Evaporation Credit Service. We work directly with the water utility to get them enrolled in the water utility program.

Hereʼs is the Cash Flow Analysis, which is used for clients to decide which ECS program to enter. This particular analysis is used in an area that requires an upfront designated time period in which monthly meter readings are required to establish a baseline credit. Once the baseline credit is established, the client receives a retrocative credit for the baseline collection period. In this instance, the client enrolls in the Cooling Tower Monitoring program for the baseline collection period, then adds on the Evaporation Credit Service once the credit is established, and we get them officially enrolled in the water utility program.
