By Ed Butts, PE, CPI Water Conservation and Management Plans The plans are growing in popularity, so make sure you know how to construct one for your customers. n addition to the normally predictable work tasks such as engineering, design, and project management, one of the duties I regularly perform is the preparation of various studies and plans for clients. As you would expect, this work is usually varied and includes different types of reports and studies. These can include master plans, facility plans, conceptual and feasibility studies, financing studies, operation and maintenance plans, and project summary (closeout) reports. In addition, one of the most common types of plans we prepare in today’s world is water conservation and management plans. Interestingly enough, during my initial 10 to 15 years in the engineering profession, I completed only five or so of these plans. But over the past 10 years, due to ever-increasing regulations and concerns about enhancing water conservation, this type of report has now swelled to around 25 completed plans. Although most of you will never need to write one of these plans, I feel that all of us working in the water well industry must recognize the need for improving and increasing water conservation and the many techniques currently I Ed Butts, PE, CPI, is the chief engineer at 4B Engineering & Consulting, Salem, Oregon.

So let’s explore the various elements that are used in developing these very important plans and the ways we can help our customers better understand the need for water conservation and management practices. However, before we begin, it’s important to emphasize that my daily engineering practice is generally limited to Oregon and Washington. Therefore, the requirements for developing water conservation and management plans within those states constitute the majority of my experience and knowledge. The techniques and methods I will discuss, though, are fairly universal and apply to virtually all regions of the country. What Is a Water Conservation and Management Plan? Although this question is no longer as common from my clients, I can recall the days not so long ago when the question would almost always be asked when I would inform my client they would need one. Basically, the short answer is that a water management and conservation plan is a tool, nothing more or less. It’s usually developed using a somewhat equal consideration of the many competing uses for water within the affected basin and region and as a guideline for the proper allocation of the remaining water resources for future needs. To be effective, however, the plan must be flexible. If the plan is too rigid or doesn’t provide any room for any future modification or amendment, it will ultimately be a disaster for you and your client. The plan must also be scheduled to receive regular reviews and updates to provide for changes in any of the economic, regulatory, environmental, or natural science realms. Although most plans are currently developed for review by local or state government bodies, many industrial and business entities have recently recognized the potential for enhancing and protecting their business climate and provide for possible future changes by developing their own internal plans. These businesses are especially those who rely heavily on dependable and predictable water supplies for their enterprise such as wood products, nuclear power, and electronic component manufacturers. Before 1995, the need to prepare and use water conservation and management plans was generally voluntary and used as a management and policy guideline to properly manage dwindling or scarce water resources in regions where the usage was typically higher than the natural replenishment. As the population has continued to grow and the competition for a finite supply of water became more intense, government regulators began to recognize that some method for managing and conserving the available water resources in a given basin must be implemented. YOUR BUSINESS/continues on page 46 NGWA.org YOUR BUSINESS/from page 44 In Oregon, this process largely began on the state level during the late 1980s to early 1990s, although many counties and cities also recognized this need before the state and developed their own plans. Although most government bodies now have established protocol and sample outlines for their idea of the proper development of water conservation and management plans, each one must still consider the unique circumstances and regional concerns associated with the specific area and client. This simply means there cannot and should not be any “cookie-cutter” approach to the preparation of these plans. Each one must be developed considering the special factors related to the local water resources. Such factors would include seasonal depletions or additions of water; commercial, industrial, and agricultural use; municipal per capita demands; and growth patterns and several others. Components of a Water Conservation and Management Plan Although there are obvious variations in water conservation and management plans based on the needs of the specific client and the requirements of the reviewing regulatory body, there are certain elements within every plan that are generally established. Among these many components are the following. 1. Background information This section provides needed background information and a history of the client. It’s an overview in most cases and outlines the history of the water system itself with a detailed description of the water sources; the pumping, storage, and delivery systems; water rights summaries; monthly and yearly summaries of the source water usage patterns and volume; classifications, types, and volume of consumption; regulatory status; and system losses. 2. Water conservation plan This is an obvious section, but one that is often understated or not comprehensive. The water conservation element is one that must include specific concepts for saving water and address46/ November 2009 Water Well Journal ing methods of lessening the use or loss of water through lowering leakage, waste, inefficient process systems, and by lowering pressure where possible. This element is outlined in greater detail as follows. 3. Long-range water supply element This is a component of water conservation and management plans that is often neglected, but it is actually the only true way of addressing future water needs in the plan. To the extent possible, the developer of the plan must be a type of “seer” and look into the future to predict the future growth and therefore the additional water demands of the city, industry, or whatever. This generally involves requesting assistance from other agencies, such as population research or census bureaus or planning departments. In addition to predicting the future water needs, the plan must also address the potential for increasing regulation, diminishing water supplies, changes in technology, competing water uses, and water rights implications. Although there are variations between states, regions, and local bodies, anywhere from 10 to 30 years is the most common time span used for predicting future longrange water supply requirements. ● 4. Water curtailment plan Remembering that this is also a water management plan, the developer must include criteria for water curtailment during an emergency or water shortage. This element is often the most publicized and scrutinized by the media and public in the plan, so the developer needs to ensure there is equity and fairness throughout the curtailment section. Once again, there are definite variations used in curtailment sections, but I suggest the following three basic classifications commonly used for municipalities. ● Stage One: A Stage One alert is used to notify the water users of a potential, but not yet imminent, water shortage. This level of alert is used to notify the water users that a possible water shortage may occur and voluntary steps to lower water usage and consumption are immediately requested from the users. This step includes media notification including press releases, ● distribution of conservation information to users, and direct notification to larger users to request voluntary cutbacks of water— especially grounds watering—until the notice is lifted. As a sign of importance, visible water usage by the water purveyor, such as grounds watering or vehicle washing, is immediately curtailed. Due to the cooperation usually received from the water users, this step is often the only one needed to head off the need to issue a higher level of alert Stage Two: A Stage Two alert signifies an increasing level of alert and indicates an actual water shortage condition has occurred. By this time, in addition to the already activated restrictions under Stage One, increasing restrictions of water use are immediately implemented, including a voluntary restriction of all non-essential uses of water such as grounds watering, vehicle washing, sidewalk and driveway washdown, swimming pool filling, and parks and golf course irrigation. Once again, although a Stage Two alert is still regarded as “voluntary,” the impression often conveyed to the water users is that the situation is indeed becoming serious and immediate cooperation is now expected from all water users. Stage Three: Issuance of a Stage Three alert implies that a critical and imminent water shortage now exists and cutbacks of nonessential water uses are no longer regarded as voluntary but are now considered as mandatory. In addition to the already implemented restrictions under Stage One and Stage Two, additional restrictions such as a total ban on pipeline flushing, fire hydrant use where there is no fire, and all other water wastes are implemented under the threat of enforcement. For government bodies with police powers, this can mean issuing a citation for violations, while other water suppliers could suspend water delivery to the violator or use other punitive measures. NGWA.org 5. Recommeneded conservation methods Generally, it’s not enough to tell someone they must stop wasting water; some type of method must also be suggested. Various methods exist which are known to either conserve water or provide a more accurate means of tracking water losses. Among the many methods are the following. ● Increase water rates to users and implement a sliding rate scale where users who use more water pay a higher unit rate for the privilege. For example, charge all users the same flat rate for the first 1000 gallons used (or any other unit selected), and then charge an increasing rate for the next 1000 gallons used, a higher rate still for the next 1000 gallons used, and so on. This type of rate schedule provides two direct benefits to the water purveyor. It encourages conservation of water where it’s most effective— in the wallet—and it provides a method to recover the higher costs of treatment, pumping, and so forth required to produce the higher volumes of water. ● Establish a program to test all production and zonal water meters at a regular interval (five to 10 years) to verify accuracy. Verify that all master meters are sufficiently accurate at low flow rates as well as the higher volumes. The use of compound meters or multiple sizes is often needed to pick up lower flow rates at master meter sites. ● Establish a program to selectively test service meters at a regular interval (roughly every 10 years). By performing a routine series of field tests on a sufficient number of service meters, you can establish a baseline for statistically predicting the accuracy of all service meters in the system. ● Develop a public outreach and educational program for water conservation, especially in schools. This type of program can have very definite benefits as the need NGWA.org ● ● for water conservation is not only touted to the children, but the kids have a nice habit of transferring this philosophy to their parents and siblings at no cost to the water purveyor. Conduct a regular leak detection program using tone devices and visual inspection. Track water use and inspect for leaks using a division of the system into smaller and more manageable zonal distribution (subsystems) with subsystem master meters. Encourage (and offer rebates where possible) the installation of low flow devices such as low flow toilets, low flow shower heads, and drip irrigation, especially in older homes. than 200 pages in length. It’s my hope that I have provided you with enough information to at the least assist you with beginning to develop one for yourself or your customer. Until next month, work safe and smart. WWJ 6. Maps and graphics Although a written text with an explanation of all of the methods of water conservation and management is helpful and obviously needed, nothing beats a graphic for most people. A detailed drawing or sketch is what often provides a full understanding of what is stated in the text. For this reason and for clarity, I always insist on including several explanatory drawings in all of my plans. Nothing is better. 7. Implemention schedule Normally, a technical plan must include some type of schedule for implementing the recommendations. This is also true of a water conservation and management plan. A schedule for implementing each recommendation must be established that is not only reasonable, but matches the financial ability of the water purveyor as well as the expectations of the regulatory agency and the long-range water supply element within the plan. Once again, the time span for this element also varies, but it is typically within a span of 10 to 30 years. Obviously, I have only touched upon the various factors that can go into a water conservation and management plan. Depending on the specific size and scope of the water system, these plans can range from just a few pages to more Water Well Journal November 2009 47/
