Artificial reservoirs are a key element in a number of civil and industrial construction projects. They can either serve the purposes of park and garden decoration, or pursue functional goals of, for example, water supply, ground water level control and infrastructural projects. Geosynthetics play an important role in construction and maintenance of such reservoirs.

Classification of artificial reservoirs
Artificial reservoirs may be classified by application as below:
- Ponds and lakes in parks and gardens. Geosynthetics are used to make a water impermeable layer preventing water leakage. This facilitates construction of attractive and reliable reservoirs that can serve as an element of décor or a medium for plants and fish of various types.
- Reservoirs for industrial purposes. Geomembranes and other geosynthetics are used to make sealed basins for industrial water storage or effluent collection with further treatment and safe utilization.
- Irrigation water intakes. Geosynthetics may be used in agriculture via construction of reservoirs for water collection and storage at a required level for irrigation of agrarian lands. They secure waterproofing of such reservoirs.
- Resorts and aquaparks. Geosynthetics play a key role in waterproofing and durable safety arrangements with regard to pools and water rides.
- Treatment facilities and polishing lagoons. Geosynthetics are used in construction of effluent facilities, including ponds and reservoirs, for effluent treatment and further utilization. This enables effective water treatment and prevention of surrounding areas pollution.
Advantages of geosynthetics use in reservoir construction
Advanced-technology-based materials offer a number of advantages in construction and finetuning of artificial reservoirs. They assist in development of stable, durable and ecofriendly facilities.
Waterproofing capability is one of the key advantages of geosynthetics. This is particularly important for reservoir construction as it prevents water penetration into the ground and maintains the right water level in the reservoir.
Geomembranes are represented by Geospan GT PP M in Geospan range. Also present there are Geospan GT PP WA capable of waterproofing.
No less important aspect is geosynthetics’ ability to reinforce reservoir banks. They prevent water-caused soil erosion and secure the shoreline stability by preventing land slides and the reservoir deformation.
Geospan offers Geospan GC (GCP) for these purposes. Geospan GC has made a good showing in bank reinforcement and soil stabilization. This geogrid possesses high strength and capability to withstand static and dynamic loads, allowing elimination of settlement risk and extension of a reservoir service life.
Filtration and drainage functions are also an important feature secured by geosynthetics. They allow control over the moisture level by facilitating evacuatiobn of surplus water and preventing drainage system clogging.
The usage of Geospan BB filtering nonwoven geotextile is a proven solution to secure a reservoir filtration and drainage. A special way of bonding fibers of this material allows achieving high filtration and strength performance with a minimal thickness of the geotextile, as well as protecting a drainage system from clogging by fine soil particles and extending the drainage system service life.
It is important to note that geosynthetics are much more than just components of a unit, they are integral elements facilitating development of strong, functional and aesthetic artificial reservoirs. Their application enables saving natural resources and ensures a facility safety and durability thus making geosynthetics an intrinsic part of the current ecofriendly engineering approach to reservoir construction.
Conclusions
Geosynthetics use in construction and final arrangement of artificial reservoirs in various spheres, from recreation to industrial and environmental projects, enables development of innovative solutions contributing to an industry steady growth and mitigation of harmful environmental impacts.
Geospan materials have been utilized in construction of artificial reservoirs, motorways and railways, airports, ports, industrial and civil construction and many other areas since 2008. All the materials are produced to advanced technologies and are thoroughly tested in an own certified laboratory. Besides, Engineering Center closely cooperates with the geosynthetics producer’s technical support units to enable offering innovative solutions for construction of projects of varying complexity.
