The balance of water consumption and wastewater calculation methods , purpose and objectives

Water supply and sewage, as well as their preliminary design, starting from scratch for each object.Should take into account not only the specifics of the object, the area where it is located, but also the personal wishes of the developer.Attention is paid to such trifles as the purpose of the premises, the number of future users of the system, the minimum and maximum amount of water that will be used.The water consumption balance includes absolutely all the water flowing through pipes: technical, Waste, wastewater, drinking water, rain water for outside work.

purpose of drawing up the balance of water supply and disposal of waste effluents

Counting ratio of water consumption and waste water (sewage, heavy rains), it is necessary: ​​

1. to create a clear project communications,that will fully deal with water supply and discharge of waste (contaminated) liquids into the sewer;
2. to calculate the scale of the pipeline and its facilities and equipment, submersible pumps, the choice of which depends on the width of the hole (if it will be an independent source);
3. to obtain documents for permission for leave of water and wastewater reception (if the object is connected to a central pipeline systems);
4. to obtain a license, which allows use of mineral resources;
5. for drawing up and signing of contracts and agreements with local utilities.
6. Calculation of water volume, which is necessary for the use and abduction, carried out in accordance with building regulations and techniques.The count must be used technical passport data communications equipment and the specific requirements of the regulated rates of consumption.

Preparation of the water balance for contractors

Before you enter into a contract for the supply of water and sewage reception with the specifications, it is necessary to calculate the balance of consumption and exhaust.To fill this contract must be addressed to its contracting organization, which will provide a sample.Standard form can always be found on the websites of the contractors.Hydroeconomic ratio can be calculated independently, but better to entrust this work to a specialist from the organization with which you are planning to enter into a contract.

In compiling the above ratios adhere to certain rules, which can be found in the text SNIP 2.04.01.-85.The technique is determined based on the total volume of water, which depends on:

• the number of consumers;
• climate specificity;
• on infrastructure development;
• on the state of communication systems.

amount of water that must be a subscriber should include hot and cold water, water for outdoor use, as well as water, which is needed to extinguish the fire.The amount of water should include also the water that is consumed periodically.

If you are a property owner and you want to calculate the drainage, it is necessary to take into account the costs of sanitary node equipment, the volume of water discharged from the heating network in the end of the heating season, diverted rainwater.The calculation of the balance for the whole range of businesses includes spending on industrial, commercial and domestic needs.The balance sheet should include all costs for household, technical (production) and household needs.

Counter - simplification of the calculation methods with contractors

Recently, rules have been adopted, working at the state level.According to the new guidelines the cold water supply and sanitation should be used only in conjunction with a special counting equipment.According to the testimony of this technique can be used to determine the amount of water to the last drop.Purchase, installation and control of the counter carries out directly to consumers.

Installation of equipment of this type eliminates a number of problems: the need to count in different seasons of the year costs to prevent conflicts and disputes between the organization and the customer.

volume of water that has been used up is determined by the bandwidth of communication only if:

not install the equipment for measurement has been made;
measuring technique has no seals or they were thwarted;
the illicit connection inflow or outflow of water from the system;
access to meter reading equipment is not available.

Remember that in violation of at least one item of the contract, payment of the consumption will be calculated based on water consumption.

methods of calculation and payment services

When set counter calculation method with an organization that supplies water and wastewater takes quite simple.Data taken from the counting equipment on the volume of supplied cold water must be multiplied by the tariff.Similarly, counts the number of hot water.The findings are summarized, payment for services performed under this amount of VAT.

When averaged limits apply?

independent building owners, members of LCD and full apartment owners, who do not have meters and enter into relationships that bind the contract with the contractor, on the question of the calculation of wastewater will get a completely different answer.The final value for the payment in these cases will be considered as specified by local standards organizations, which have been calculated on the basis of average data on water consumption in a particular region.Installed cost is recalculated every year, updated and communicated to the public through local media.

use of average rates for the individual calculations of consumption and disposal of water is not very beneficial for the consumer.Average limit includes a fairly large set of additional costs that should be allocated to zhiltovarischestvo home or a group of users.Rarely do they all have the desire and the desire to maintain communications and sewer systems in good technical condition.Those water loss that occurred as a result of accidents or repairs, also distributed among the subscribers, who do not have meters installed.It is therefore very advantageous to have a private counting equipment.

few words in conclusion

accurately calculate the consumption and disposal of water balance - important and necessary parameter that is taken into account when designing networks.Also, he will need to draw up a contract for the supply of water and the outflow of liquid waste into the sewer.
