Interior design ideas

At creation of a bowl the form and the sizes of the future reservoir is defined. Various materials are being used depending on features of a site and type of a reservoir.
If there is clay the waterproof bowl can be made of it. But, despite of availability of a material, ramming of clay is a quite labor-consuming process. Besides in due course roots of plants sprout in a clay layer, destroying it.
Expenses for construction of a bowl from concrete are high, but are not always justified, especially if the prospective reservoir will borrow the small area. Concrete bowls are usually made for greater ponds of geometrical forms. It is more complex to make bowls of the wrong form. And very seldom this material is used as a box for a stream or the cascade.
Ease of installation, durability, and rather low price concern to advantages of ready plastic forms. The basic lack consists in already made forms and small depth (on the average - about 60 cm). The bowl of the future reservoir can be made of fiberglass. For this purpose dredging is being made in a ground, and then it is being covered with fiber glass and filled in with polyester pitch. Essential advantages of a similar design rely in absolute freedom in a choice of the form and the structure and high durability. However, the cost of a bowl from fiberglass is quite high. Besides for the period of hardening pitch dry weather is required.
Pump is the basic element of reservoir technical system. For example, it takes away water from the bottom pool and lifts in top in the cascade. In a pond the pump creates movement of water and sates it with oxygen.
At a choice of the pump it is necessary to remember that fragments of plants get into the open reservoir and silt is being formed at the bottom. Therefore usually use two types of pumps: or special pond pumps created for work in conditions of an artificial reservoir, or drainage, calculated on swapping of???????? soft-polluted liquids. Working elements of pumps of both types are made of high-strength stainless steel or composite materials. The electric part is reliably isolated by special pitch condensation so that it is possible to arrange pump right in the reservoir.
