Do Suppliers of Pressure Relief Valves for Water & Wastewater Treatment Face Any Roadblocks?

Water supply and sanitation infrastructure is majorly hold by public/ government authorities in majority of countries. The governments in these countries generally function through releasing tenders for companies, which are either state-owned and follow government guidelines or are privately-owned but have to follow government guidelines in order to run the business smoothly.

Tendering process is being implemented by a variety of different ministries and levels of government through different policies, laws, and decrees, which sometimes might be overlapping or leave gaps, making it quite difficult to identify who is really responsible for any of the given aspect of water management.

Also, governments in these nations have implied certain sets of regulations that are often found favoring local companies, making it difficult for foreign players to enter.

Will Sales of Pressure Relief Valves Gain Traction Due to Ideology of Smart City and Smart Water Adoption?

Smart cities encompass six important sectors that need to work in unison to achieve a common goal of making a city more livable, sustainable, and efficient for its residents. These sectors are smart energy, smart integration, smart public services, smart mobility, smart buildings, and smart water.

Smart water is a very crucial vertical of a smart city plan, due to the fact of limited natural resources and increasing per capita consumption. Smart water technologies include those that automate monitoring and metering, treatment and distribution functions, loss and leakage, and metering and usage. These ‘smart’ components are a suite of automation and monitoring technologies tied together by a network-based human interface and control component.

In utility and industrial settings, smart water is governed by supervisory control and data acquisition (SCADA) systems while consumer interfaces can take the form of any combination smart meter and consumption management technologies, including web-enabled versions for personal mobile devices. These technologies are expected to escalate demand for remote operated pressure relief valves.

How is Limited Availability of Fresh Water Driving Demand for Pressure Relief Valves?

Over the past decade, availability of fresh water has declined significantly across the globe. In addition, water pollution has witnessed steady increase. Moreover, growing industrialization has, in turn, resulted in significant increase in volumes of generated waste water, especially from energy & power generation, municipal water, and effluent treatment plants.

According to the UN Water report, out of the total water available on the Earth’s surface, only 0.5% is fresh water that can be used for consumption, and 60% of this available fresh water is unevenly distributed, with a major share concentrated among ten countries in the world. As a result, many regions suffer from water scarcity and water stress.

For instance, MEA accounts for a mere 1% share of the available fresh water resources across the globe. The region, thus, faces severe water scarcity and water stress.

Efforts toward conservation and water treatment are, in turn, expected to drive demand for produced water treatment systems across the globe.

Which Region Offers the Largest Opportunity for Sales of Pressure Relief Valves for Water & Wastewater Treatment?

China, being one of the largest reservoirs of shale gas, wherein, requirement for pressure relief valves for steam handling becomes one of many important measures for safety. China has high demand from its domestic market, and also earns significantly through exports.


Country-wise Analysis

Why is the Market for Pressure Relief Valves for Water & Wastewater Treatment in the U.S. Attaining Maturity?

The market in the U.S. grew 2% from 2016 to 2020. The nation's more than 16,000 wastewater treatment plants are operating at 81% of their design capacity on average, with 15% exceeding it.

Growing urban surroundings indicate that these facilities will be able to handle a higher share of the nation's wastewater demand in the future indicating that there are less chances of fresh procurement for pressure relief valve on a large scale.

Moreover, in 2019, overall capital spending on water infrastructure at all levels was at US$ 48 Bn compared to US$129 Bn in capital investment needs, resulting in a US$ 81 Bn shortfall. This exemplifies a long-term trend of under-investments in key water infrastructure such as drinking water and wastewater systems.

Only 37% of the nation's total water infrastructure capital needs were met due to this deficit. If the water and wastewater sectors continue on their current trajectory, the total shortfall will reach US$ 434 Bn by 2029.

Category-wise Insights

Why are Pilot Operated Pressure Relief Valves the Most Used?

Pilot operated pressure relief valves account for around 33% share of the global market. These are also known as pilot-operated safety valves (POSVs), pilot-operated pressure relief valves (POPRVs), or pilot-operated safety relief valves (POSRVs), depending on the manufacturer and the application.

This type of valve has numerous advantages such as smaller package on larger pipe sizes, more options for control, seals more tightly as the system pressure approaches but does not reach set pressure, and control pilot can be mounted remotely.

This type of valve is mostly used where hot water or steam is the transferred medium.

Which Size of Pressure Relief Valves Generates Most Revenue?

6 to 12 inch pressure relief valves accounted for over 50% demand in 2020. The size of the valve must match the size of the input and discharge pipes. Both, the intake and discharge pipes linked to the valve must be at least as large as the inlet/discharge opening on the valve itself, according to the National Board.

Majority of pipes in the oil & gas industry as well as in municipal water facilities come under the bandwidth of 6 to 12 inches of pressure valve ratings, thereby driving demand for this size.

Which Flow Rate Bandwidth Holds Lucrative Opportunities for Pressure Relief Valve for Water & Wastewater Treatment Manufacturers?

By flow rate, 2,500 to 5,000 gpm pressure relief valves held as much as 1/3 of the market share in 2021. This is because of the same fact mentioned above, most end users have such large flow rate pressure relief valves. Urban wastewater treatment plants install these valves with larger flow rate in order to cope up with surging waste produced each day round the year.

What Operating Pressure is Most Popular for Pressure Relief Valves?

100 to 300 psi pressure rating valves are the most sold and will expand at a CAGR of 4.5% during the next ten years. Water supply & distribution, water treatment plants and municipal sewage treatment plants operate mostly in this range of pressure, making the 100 to 300 psi range a lucrative segment.
