When drawing up estimates for external water supply, it is necessary, first of all, to determine the source of water supply. The basis for the water supply project will be the estimated need for drinking and technical water and the requirements for its quality, as well as the plan of the facility indicating the necessary points for water supply. Based on this, the construction of pumping stations, treatment facilities and filtration tanks may be required.

The arrangement of external water supply should take into account the depth of pipe laying, which depends on the degree of soil freezing and varies by region. It is necessary to provide for the laying of sewer networks below water pipes and other requirements of SNiP.

The costs of arranging internal water supply networks include: the cost of acquiring pipes, valves and equipment, payment for laying water pipes across the territory, distributing them through buildings and structures, installing valves, connecting the system to an external water supply. With a weak water pressure, the costs of purchasing and installing pumps are added.

The estimate for the water supply includes payment for commissioning and takes into account the costs of compiling design and estimate documentation.

Drawing up estimates for water supply networks will make it possible to determine the cost of upcoming work and plan funds for their implementation.

The main difficulties and mistakes
with independent design:

1. Lack of an agreed project of the Sanitary Protection Zone (SZZ)
2. Lack of metering devices and objective (calculated) data on the required productivity.
3. Lack of title deeds to the land.
4. Inaccuracies in the preparation of the Terms of Reference: all the necessary studies were not taken into account, the documents listed above were not taken into account.
5. The justification of the price was performed incorrectly, on the basis of commercial proposals of non-specialized organizations, without taking into account the fulfillment of the requirements of technical conditions, the need for inspection of buildings and structures, etc.
6. Surveys, research, and design are performed by different companies, which causes delays and additional work.

 Decisions from
Company "Gutman Construction":

• We will analyze the existing situation, prepare the Terms of Reference for the SZZ project. If necessary, we will execute the project of SZZ and agree on it.
• We will collect all the necessary data, make calculations and submit it to the customer for consideration. If necessary, we will temporarily install metering devices.
• We will help in the preparation of documentation, if necessary, we will include it in the TOR for design.
• We will analyze the existing situation and prepare the correct technical task.
• We will prepare an estimate for design and exploration works and surveys, based on basic price guides.
• We have considerable experience and qualifications for the organization of a full range of design and search works. Company "Gutman Construction" has SRO permits for both design and exploration work. We are guaranteed to provide a positive conclusion of the examination and support during SMR.
