WMI designs and implements water efficiency programs for industrial, commercial and institutional customers in a multitude of sectors. WMI also provides innovative domestic, non-domestic, and sustainability conservation measures for public housing, prisons, multi-family clients and water utilities. We are constantly testing new products in our laboratory and in the field to determine their applicability to our programs, and we pride ourselves on being on the cutting edge of water-saving technologies.
Our development and installation capabilities include the latest in conservation measures for:
 |
Toilets, faucets and showers |
 |
Laboratory equipment retrofits |
 |

In addition to this broad solution set, WMI has many healthy and successful strategic partnerships allowing us to provide conservation solutions in steam, solar thermal, water re-use, and other sustainable technologies.
WMI's team of established project developers and project managers remain dedicated to delivering quality customer service, from preliminary audit to close-out punch list. WMI prides itself on building strong relationships with customers that last far beyond the project completion date. Our staff knows what it takes to develop and build successful water projects because we've been doing just that since 1980. |

Water Audits
The audit process involves three steps:
 |
Conducting the audit |
 |
Development of a report that identifies water related savings (water, wastewater, energy, etc.), discusses specific potential retrofits and technologies, and provides a cost/benefit estimate for the measure so that the ICI entity can use the information to make intelligent decisions regarding water conservation |
 |
Presenting the information to the ICI entity in a format that is easily understood. |
To complete a water balance and produce a comprehensive report, the following three components of the audit will be coordinated:
 |
Outdoor water use for irrigation |
 |
Cooling tower audits |
 |
Audits of indoor and all other water uses other that irrigation and cooling towers |
 |
Metering and submetering, steam, solar thermal, water re-use, and other sustainable technologies |
WMI provides three levels of auditing to our clients:
 |

Consumption Analysis
Based on the information collected during the survey, consumption for the property is analyzed and savings opportunities are identified. Water rates are determined and unaccounted water use is identified. Building census and usage of existing fixtures is determined. WMI’s computerized software can provide a complete Water Conservation Measures Analysis that can be customized to meet the needs of each individual client. Water savings are calculated on a measure-by-measure basis and are summarized by building and by facility. |

Design
Field proven methods are used to ensure that the upgrades recommended will provide the necessary performance and savings. Design measures are often unique to each location and are based on water saving potential, cost, and return on investment. Product selection is dependent on many factors such as water pressure, use, application, and aesthetic requirements. |

Financing Options
We offer two approaches for project financing.
 |
Direct billing |
 |
Performance-based contracts |
We can bill directly for any and all of our services, or we can design a property-specific performance-based contract. Performance-based contracts are available in two forms: shared savings and guaranteed savings.
Shared Savings - In exchange for implementing a water-efficiency program, WMI receives a share of the savings generated. We underwrite all initial equipment, installation, and subsequent inspection and repairs. We concern ourselves with every aspect of the water supply system that has potential to waste water. Any payment to us on a Shared Savings contract is a testament to our water-efficiency program's success and indicates that your property is using less water than before the program began.
Guaranteed Savings – In this program we implement the program for an agreed upon up-front fee. We then guarantee that a certain level of savings will be attained throughout the length of the agreement. We design our programs so that the savings guarantee exceeds the note payment. Excess savings are sometimes shared in return for the savings guarantee. These programs usually last between 7 – 10 years.

Measurement and Verification
WMI believes that the measurement and verification of savings on a program such as this must be assured. Although water and sewer cost reductions are quite a bit less complicated than energy savings, we believe a protocol must be established from the startup. We support DOE’s efforts to standardize the methodology with the IPMVP (International Performance Measurement and Verification Protocol) – in fact we helped write the book. Tom Horner, vice president, of Water Management served as the co-chair of the Water Subcommittee. |

Training
The goal of our training program is to enlist the enthusiastic support of everyone for the conservation program, and to leave the job site with maintenance personnel fully capable and confident to keep the systems in good working order.
A video presentation is often provided and is organized throughout the implementation and construction phase of the program. During these sessions, the objectives of the program will be presented to the staff. Methods to further reduce water and energy consumption will be discussed.
It is generally recognized that energy and water savings can be achieved if all make a concerted effort to reduce consumption. Further, the best conservation measures will not achieve optimum savings if there is not a reasonable level of cooperation from the users.
Classes for the maintenance personnel will instruct staff in repair and preventive maintenance techniques and will also teach personnel how to read meters and calculate usage.

Metering
Non-revenue-water is typically expressed as a percentage of the total amount pumped or purchased. EPA’s Office of Water states that one of the most important water efficiency measures that municipalities need to implement is a water‐loss management program that is aimed at achieving the water industry goal of 10% or less for unaccounted‐for‐water.
There are many potential sources of system water losses including fire hydrant flushing, evaporation, and theft. The source that often gets the most attention is system leaks in the mains and services. However, the area that has the most effect on the bottom line is the water losses due to metering problems. A study submitted at the 1999 Water Sources Conference, stated that for most utilities, the revenue lost because of under‐reporting of water meters is more than 10 times greater than the cost of water lost from system leaks.
AWWA estimates that for many large utilities, as many as half of all commercial meters are under‐reporting. A study completed by Brown and Caldwell for Asheville, NC found a failure rate of 56% for compound meters, 33% for turbines and 46% for small meters. Water Management’s first-hand knowledge of water auditing and experience as a leader in water efficiency puts us in a very unique position. We are able to identify with uncanny accuracy water meters that are under‐reporting consumption. To learn more about the problems that can occur with commercial meters

Leak Detection
When most pipelines begin to fail, they do so slowly beginning with leaks at poor construction joints, small structural cracks, and points of corrosion. The WMI Leak Detection Team locates and fixes these troublesome, costly water leaks before water use and water bills get out of control.
WMI can record the flow of a building's water by using computerized sensor technology. Also, with the use of electronic sound equipment, we can amplify raw leak sounds by selectively filtering out distracting sounds and honing in on the unusual sound of a leak. Once our detection team determines the location of the leak, they review all information gathered with the customer to determine the best course of action that would quickly and effectively eliminate the problem. |
