Climate change, drought, and chronic overdraft represent growing threats to the sustainability of water supplies in dry environments. The Monterey/Salinas region in California exemplifies a new era of integrated or “one water” management that is using all of the water it can get to achieve more sustainable supplies to benefit cities, agriculture, and the environment. This program is the first of its kind to reuse a variety of waters including wastewater, stormwater, food industry processing water, and agricultural drainage water. This study investigates the partnerships, projects, and innovations that shape Monterey’s integrated water network in order to better understand the challenges and opportunities facing California communities as they seek to sustainably manage peri-urban water supplies. Water reuse in the Monterey region produces substantial economic and environmental benefits, from tourism and irrigation of high-value crops to protection of groundwater and increases in environmental flows and water quality. Water resource managers in other communities can learn from Monterey’s success leveraging local needs and regional partnerships to develop effective integrated water solutions. However, key challenges remain in resolving mismatched timing between water availability and demand, funding alternative water supplies, and planning effectively under uncertainty. Opportunities exist to increase Monterey’s recycled water supply by up to 50%, but this requires investment in seasonal storage and depends on whether desalination or additional recycling forms the next chapter in the region’s water supply story. Regulatory guidance is needed on seasonal subsurface storage of tertiary-treated recycled water as distinct from potable recharge. By increasing the supply of recycled water to Monterey’s indirect potable use system, the region’s potential need for seawater desalination may be delayed as much as 30 years, resulting in cost and energy savings, and giving the opportunity to resolve present planning concerns.

Most tanneries use conventional systems for treatment of the mixture of all production effluents. Such an approach makes it possible to meet environmental regulations, but because of the high cost of the treatment facilities, its implementation has been scarce, especially in developing countries. With the waste reduction-elimination concept in view, an alternative strategy for water management is proposed based on individual treatment of the effluents from different processing steps to obtain multiquality recycled water for various reuse purposes, materials recovery and complete reuse of treated water. The methodology includes a database generation of tanneries in Mexico, a mass balance and pollution index determination, formulation of water management scenarios and technical-economical evaluation. To replace the traditionally used sulfide oxidation, a sulfide recovering was proposed. Chromium, grease and protein recovery were considered too. The proposed alternative allows a 90% fresh water reduction, the recovery of more than 95% of chromium and sulfide, 90% of grease, 65% of protein and zero discharge of wastewater. Simultaneous implementation of various water saving methods using in-house wastewater treatment techniques for recovering of chemicals and sub-products reduces substantially the cost of water management.

Abstract Recycling of effluent water from urban water-supply systems is often a more sustainable water source than increased use of surface sources, groundwater sources, and desalination. However, water-supply organizations (WSOs) often do not take full advantage of recycled water. Although recycling water for direct potable use is efficient, public concern with safety has tended to cause WSOs to favor other uses for recycled water. This study examines patterns in the degree of utilization of two main indirect uses of recycled water: dual-reticulation systems and groundwater recharge. Drawing on case studies of four U.S. cities that are leaders in the use of recycled water, the study identifies conditions that favor the choice of one option over the other. Where cities are concerned with groundwater recharge of potable water supplies, they tend to prefer non-recycled water if available for recharge projects. However, where non-recycled water supplies are limited, recycled water may be prioritized for aquifer recharge. Otherwise, the preference is for use by large industrial partners such as power plants or for exchanges for higher-quality potable water resources with rural systems. In contrast, dual-reticulation (purple-pipe) systems for direct nonpotable recycling face steep economic and technical challenges.

Irrigation Districts

Irrigation districts play a decisive role in Portuguese agriculture and require the adaptation to the new water management paradigm through a change in technology and practices compatible with farmers’ technical know-how and economic sustainability. Therefore, improvement of water management, focusing on water savings and increasing farmers’ income, is a priority. In this perspective, an applied research study is being carried out on the gravity-fed Lis Valley Irrigation District to assess the performance of collective water supply, effectiveness of water pumping, and safety of crop production due to the practice of reuse of drainage water. The water balance method was applied at irrigation supply sectors, including gravity and Pumping Irrigation Allocation. The average 2018 irrigation water allocated was 7400 m3/ha, being 9.3% by pumping recharge, with a global efficiency of about 67%. The water quality analysis allowed identifying some risk situations regarding salinization and microbiological issues, justifying action to solve or mitigate the problems, especially at the level of the farmers’ fields, according to the crops and the irrigation systems. Results point to priority actions to consolidate improved water management: better maintenance and conservation of infrastructure of hydraulic infrastructures to reduce water losses and better flow control; implementation of optimal operational plans, to adjust the water demand with distribution; improvement of the on-farm systems with better water application control and maintenance procedures; and improvement of the control of water quality on the water reuse from drainage ditches. The technological innovation is an element of the modernization of irrigation districts that justifies the development of multiple efforts and synergies among stakeholders, namely farmers, water users association, and researchers.

Rapid Urbanization

Significant energy resources are used for water supply in Jing-Jin-Ji region with the rapid urbanization and economy increase. Yet the interrelations between water and energy have not received adequate attention in the country. In order to fill this gap, this paper performs a regional-level quantitative assessment of electricity consumption on water produce (including water extraction, desalination and recycled water reuse), as well as analyzed carbon dioxide emission caused by energy used in 2015. The results show that total energy consumption for water supply amounts to 255.63 million kWh of electricity, and 0.27 million ton of carbon released in water supply progress. Due to the differences in water supply structure and water use amount, the energy consumption and carbon release of water supply in Hebei province is higher than Beijing and Tianjin city. Given increasing water supply demand, the implementation of the most stringent water management system may increase the energy consumption, and the trend of future climate change is not conducive to the conservation of water resources and energy in Jing-Jin-Ji region.

This paper presents and discusses the keys of success of a water reuse project for landscape irrigation and other urban uses in Bora Bora, French Polynesia. To better preserve public health and overcome all constraints and public opposition, a membrane tertiary treatment for the production of high-quality recycled water was implemented. Special attention was paid to the reliability of operation and economic viability of membrane treatment, as well as to active public participation with involvement of all stakeholders. The demand for the new recycled water steadily increased during the last two years with a wide diversification of urban uses, not only for irrigation, but also for cleaning, industrial and commercial uses and fire protection. Monetary and non-monetary benefits have been assessed and recognised. As a result of this successful project, new recycling projects are under development.

This paper presents and discusses the role of community engagement, i.e. attitudes of local stakeholders, engagement of elected officers and pricing, towards the success of water reuse on the island of Bora Bora, French Polynesia. To better preserve public health and overcome all constraints related to public perception, a membrane tertiary treatment was implemented for the production of high-quality recycled water. Consequently, the demand for the new recycled water has steadily increased during the last four years with a wide diversification of urban uses including irrigation, cleaning, industrial and commercial uses and fire protection. The primary keys to success of this water reuse scheme are the strong commitment of elected officers and large industrial users with the implementation of an adequate public communication and education programme. The resulting outcome is the public trust in recycled water and the recognition of the economic and environmental benefits of water reuse with perspectives for new water reuse projects.

Development And Management

This study examined the challenges of water resource development and management in Zing town,Taraba State, Nigeria. The study considered issues of sources of water supply in Zing town, the nature of water challenges, impacts of the water challenges on the socio-economic life of the people, water management strategies and prospect of urban water resource development in the study area. 110 questionnaires were systematically administered in ten streets that were purposively selected in Zing town. The data were analyzed using descriptive statistics. The result of the finding indicates that majority (45.5%) of the respondent have their water source from borehole, 18.2% streams, 18.2% hand dug wells and 9.1% from other sources (mostly water vendors). The study shows that 68.2% of the respondents had their water point located outside their households, while only 31.8% claimed to have their water sources located within their compounds (this is mostly hand dug wells). The nature of water challenge in the area ranges from severe (50%), not severe (27.3%) and normal (22.7%). The results also shows that only 34% of respondents claimed to have access to sufficient water daily, while 66% of the respondents hardly have access to sufficient water on daily basis. The study shows that the water management strategy adopted mostly by the respondent ranges from storing water in large container (48.2%), reduce water use (29.1%), increase amount spent on water (13.6%) and others 9.1% (mainly re-use of water). The prospect of water resource development in the study area is very bright with the proposal of a small earth dam in Monkin settlement by the Federal Government of Nigeria. The Monkin small earth dam which is meant to generate 500KW of electricity can be integrated into an urban water supply project in the area. This will assure more reliable water supply all year round. It will also help to overcome some of the challenges of servicing the hand pumps which rendered them inadequate when they break down. This study recommends the need to replace the old and obsolete borehole equipment with new ones and increase the number of boreholes to meet the increasing water demand in the area.

The City

The City of Baltimore, Maryland is one of many US cities faced with challenges related to increasing potable water demands, diminishing fresh water supplies, and aging infrastructure. To address these challenges, the City recently undertook a $7M study to evaluate water supply and treatment alternatives and develop the conceptual design for a new 120 million gallon per day (MGD) water treatment plant. As part of this study, an innovative raw water management tool was constructed to help model source water availability and predicted water quality based on integration of a new and more challenging surface water supply. A rigorous decision-making approach was then used to screen and select appropriate treatment processes. Short-listed treatment strategies were demonstrated through a year-long pilot study, and process design criteria were collected in order to assess capital and operational costs for the full-scale plant. Ultimately the City chose a treatment scheme that includes low-pressure membrane filtration and post-filter GAC adsorption, allowing for consistent finished water quality irrespective of which raw water supply is being used. The conceptual design includes several progressive concepts, which will: 1) alleviate treatment limitations at the City's existing plants by providing additional pre-clarification facilities at the new plant; and 2) take advantage of site conditions to design and operate the submerged membrane system by gravity-induced siphon, saving the City significant capital and operations and maintenance (O&M) costs. Once completed, the new Fullerton Water Filtration Plant (WFP) will be the largest low-pressure membrane plant in North America, and the largest gravity-siphon design in the world.
