UK Government launches fund to help farmers manage water resources.

 UK Government launches fund to help farmers manage water resources.



The UK government has launched a £1.6 million fund to support groups of farmers in managing water resources to combat drought and ensure food security. The fund will finance approximately 20 studies exploring various water management methods, including multi-farm reservoirs, treated waste-water recycling, and water trading and sharing schemes. This initiative follows the Prime Minister's Farm to Fork Summit commitment to enhance local water resource schemes, supporting food production and building resilience against water scarcity.

Water Minister Robbie Moore emphasized the importance of water storage for dry periods to sustain food production and farm business resilience. Environment Agency Chief Executive Philip Duffy highlighted the growing need for water due to climate change, increased demand, and environmental protection, estimating an additional 5 billion litres daily by 2050.

The fund aims to expand successful projects like the Felixstowe Hydrocycle, which repurposes excess drainage water for irrigation, and the Lincoln Water Transfer, where 19 farms share a water abstraction license for flexible land and water use. The Environment Agency will collaborate with farmers and other stakeholders to integrate agricultural needs into Regional Water Resources Plans, enhancing overall water resource efficiency and supporting a robust farming sector. This funding complements existing government measures, such as the Water Management Grant and ambitious leakage reduction targets for water companies.

 The 143rd Annual Conference and Exposition (ACE24) of the American Water Works Association


AWWA ACE24 of hosted by american water works association sessions & exposition took place at the Anaheim Convention Center in Anaheim, California (800 W Katella Ave, Anaheim, CA 92802) from June 10-13, 2024.

More than 10,000 people gathered in Anaheim, California, from June 10-13 for the 143rd Annual Conference and Exposition (ACE24) of the American Water Works Association, themed "Transforming the Future of Water." The event includes 18 professional tracks, 190 sessions, and 719 presentations on topics such as water treatment advances, PFAS, water quality, resources planning, regulatory issues, and workforce transformation. Additionally, the exposition featured over 440 exhibitors and 1,090 booths, with an Innovation Hub for emerging technologies.

ACE24 commemorated the 50th anniversary of the Safe Drinking Water Act, celebrating advancements in public health protection and ongoing challenges. The AWWA, in its Water 2050 initiative, emphasizes sustainability with new measures like a carbon offset program for travel, recycled conference bags, and donations of exhibit materials to local communities.

Salute to everyone who makes efforts to protect the world's water resources.

Today, SJZ Metalsin Tech Co LTD can contribute to water resources. In terms of water supply, SJZ Metalsin can provide:

Which country is the largest water resources in the world?

 Which country is the largest water resources in the world?

The country with the largest water resources in the world is not the United States, not Russia, and not Canada, But Brazil.
Brazil map

Brazil location.

Brazil is located in the eastern part of South America, bordered by the Atlantic Ocean to the east. Most of the country is situated in tropical regions. In the northern plains of Brazil, there are three major river systems: the Amazon, the Paraná, and the São Francisco. In the southwest, there is the Itaipu Hydroelectric Power Plant, known as the Brazilian Hydroelectric Hub. Brazil possesses over 20% of the world's water resources, with an average total water resource volume of 69.5 trillion cubic meters, accounting for about 15% of the global total. The per capita water resource is 32,000 cubic meters, roughly four times the global average. However, due to its large population base, Brazil faces a severe water resource crisis.

How is Brazil addressing the water resource crisis:
Amazon River

1) To address the issue of uneven water resource distribution, Brazil is improving its water resource allocation system to achieve reasonable distribution and utilization of water resources. This can help reduce the imbalance of water resources between different regions.

2) To address the issue of underutilized geographical advantages, Brazil can enhance infrastructure development to leverage its geographical benefits, thereby improving transportation convenience. This can better promote local economic development and provide more opportunities for the utilization of natural resources.

3) By strengthening international cooperation, Brazil can fully utilize transboundary river resources to achieve resource sharing and mutually beneficial cooperation. Additionally, through ecological protection and sustainable development practices, it can achieve a win-win situation for both the economy and the environment. This approach ensures that the utilization of natural resources is not merely about exploitation and consumption but also about sustainable utilization.

Why Saudi Arabia in the desert country doesn't shorage of water? and what the fresh water is double than China.

 Saudi Arabia's location and water resources condition.


Saudi Arabia, located in the central Arabian Peninsula, borders the Persian Gulf to the east, the Red Sea to the west, and shares borders with Iraq, Jordan, Kuwait, the UAE, Oman, and Yemen. Connected to Bahrain via the King Fahd Causeway, its terrain is mainly composed of plateaus, with deserts covering approximately 40% of its land, making it the country with the second-largest desert area globally. Despite being one of the most water-scarce nations with annual rainfall of only 100-200 millimeters and extreme temperatures up to 54 degrees Celsius, Saudi Arabia's per capita daily water usage was 271 liters in 2016, nearly twice the global average and third highest worldwide. 

How does Saudi Arabia obtain water resources?


Since the 1980s, Saudi Arabia built over 200 dams to capture rainfall, but this only provides 10% of water due to scarce rainfall and high evaporation. Initially, they relied on groundwater, which at its peak supplied 40% of water needs, but this source quickly became unsustainable due to depletion.

Seawater desalination is Saudi Arabia's main water source, initiated in the 1990s. By 2020, the country became the world's largest producer, with a daily capacity of over 5.6 million tons, 20% of the global total. The state-owned SWCC operates nearly 40 plants and a 5,000-kilometer pipeline network. This has resolved the country's drinking water needs and some industrial requirements, supporting its development.

The methods of seawater desalination.


Seawater desalination is the process of removing salt and other impurities from seawater to produce freshwater suitable for human consumption and other uses. There are two main methods of seawater desalination:

1) Reverse Osmosis (RO): In this method, seawater is forced through a semipermeable membrane that allows water molecules to pass through while blocking salts and other impurities. Pressure is applied to overcome the osmotic pressure and separate the freshwater from the concentrated brine.

2)Multi-Stage Flash Distillation (MSF) and Multi-Effect Distillation (MED): These methods involve heating seawater to produce steam, which is then condensed to produce freshwater. In MSF, seawater is heated in multiple stages, with each stage at a lower pressure, causing successive flashes of evaporation. In MED, seawater is heated in multiple evaporator stages, with each stage at a lower temperature and pressure, allowing for water vapor to be produced.

The gate valve standard in the seawater desalination.


Gate valves for seawater desalination must resist corrosion, provide excellent sealing, be durable, require minimal maintenance, and be made from corrosion-resistant materials to meet the process's unique challenges. The standards is include AWWA C515, BS5150, API600, ISO10434.
