Project in large-scale for efficient water supply management leads to million-dollar savings

Georgian Water and Power (GWP) has chosen AVK International to supply more than 500 pressure reducing valves (PRV's) in order to significantly enhance and efficiently manage their water supply.

A critical water loss at around 70% in the Tbilisi-region has formerly given rise to a leakage reduction initiative. Now, GWP has decided to go all the way to obtain an efficient water supply management, and 150 PRVs already installed as part of the initiative are to be replaced by AVK valves in addition to more than 350 new PRV installations. The expected savings on water production is more than six million USD every year.

Quality matters

We supply high quality solutions and our prices are not always able to compete with the cheapest options. However, it was clear from the beginning that GWP was looking for high quality and dedicated support, and after technical discussions with our experts, they concede the benefits of AVK valves. 

Pressure management for minimising water loss

The benefits of pressure management are many for both consumers and water utilities as well as for sustainability. It has proven to efficiently decreases the leakages and thereby also lower the non-revenue water level. So it improves energy efficiency as well as operation and maintenance costs. Pressure management using PRVs can really make a difference and besides savings on produced and pumped water it can also enhance e.g. consumer satisfaction by minimised amputations. One of the major benefit of pressure management in the Tbilisi region is specifically the allowance for control of the excess pressure that ascend as the water flows from the high situated reservoir.

Reduced water distribution and less pipe bursts

After installation of 235 of the total 500 PRVs effective results are already seen. The overall water distribution in the supply area has been decreased by seven percent compared with the past year, and the consumption of electricity for water treatment and distribution has been decreased by approximately 10 percent. The risk of water hammer has also been decreased and 25 percent less pipe bursts are seen. The pumped water is reduced by 76,000 m³ per day meaning that at the moment, GWP saves 27,740,000 m³ of water per year.  

Savings Of Million dollar 

After installation of all of the 500 PRVs, GWP expects the quantity of pumped water to be decreased by 58.000.000 m³ per year. As the total estimated cost of producing one cubic meter of water in Tbilisi is around 0.11 USD, the savings alone on producing this amount of water will be nearly 6.4 million USD per year. Impressive numbers that are within reach for the Georgian water supplier and the consumers in Tbilisi.

High quality water supply
