Explanatory Note

"A working project for laying water supply to a residential building at the address: Moscow Region, Leninsky Ron, Garden. Comrade "Rumyantsevo," publication No. 43 "was developed on the basis of contract No. P2006/VBR dated 01.06.2006.

Input for project development:

- Specifications for water supply to Moscow State Unitary Enterprise Mosvodokanal No. 213470/5 (o) -1 dated 20.12.2005

- Floor plans of BTI as of 10.09.2002

- The plan of the house at el. 0.000 - customer sketch.

- Section A-A (cellar) - customer sketch.

- Detail of well No. 83040 - a sketch of the area of ​ ​ water supply network No. 12.

- Situation plan M 1:10000.

- Moscow City Geotrest State Unitary Enterprise 1:500 Order No. 3/33680603.04.2006

The following were used as guidelines for the design:

- SNiP 2.04.0284 * "Water supply. External networks and structures. "

- SNiP 2.04.0185 "Internal water supply and sewerage of buildings "

- Manual for the design of residential and civil buildings. Section 16 "Water supply, sewerage, gas supply, drains." Series 16 "Water metering units." JSC Mosproekt.

- Album PP1618 "Water meter inserts." JSC Mosproekt.

- SP 401062002 "Design and installation of underground water supply pipelines using pipes from high-strength cast iron with spherical graphite."

In accordance with the specification for water supply, the project includes:

1. Water supply to a residential building laid in an open way.

2. Water metering unit behind the first one from the water supply by the external wall of the house.

In accordance with the specifications of Moscow State Unitary Enterprise Mosvodokanal, the water supply of a residential building is provided by laying a water inlet Ø50 mm from the well No. 83040 of the Moscow water supply network Ø500 mm to a residential building.

The design provides for a tie-in to the existing Ø500 mm steel water supply in well No. 83040, which houses the Ø50 mm isolation gate valve and the laying of a water inlet from Ø50 mm cast iron pipes from high-strength cast iron (HShG) with ball graphite, with an internal cement sand coating and external galvanizing made by hot galvanizing.

The water supply is laid in an open way in a trench with a depth of 2.02 2.4 m with vertical walls and inventory fixation with boards.

The total water consumption for household needs from the Moscow water supply system in accordance with the specifications for water supply of MGUP Mosvodokanal No. 213470/5 (0) -1 from 20.12.2005 is 1.22 m3/day.

Accounting of consumed water is carried out by VSH25 water meter provided as part of the water metering unit located in the basement (cellar) of a residential building along the external wall along the facade of the building.

The basement room has an internal temperature not lower than +4˚S, lighting sufficient to take water meter readings and is equipped with an electric socket for connecting electrical measuring devices.

Storage of any objects and material assets is not allowed in the basement room.

Installation and replacement of the water meter, sealing of the gate valve on the bypass line of the water metering unit and the water meter are carried out by MGUP Mosvodokanal.

All work on the connection of the residential building to the Ø500 mm pipeline should be carried out under the technical supervision of the area of ​ ​ the water supply network No. 12 of the Mosvodvodvodvodod Production Directorate, for which the customer needs to conclude an agreement with the latter. Construction works cannot be started until the conclusion of the contract for technical supervision.

The water supply completed by construction is submitted for delivery to Mosvodokanal Moscow State Unitary Enterprise with the simultaneous submission of the documentation listed in the "Rules for the use of Moscow city water supply and sewerage systems" paragraph 2.13.

Prior to commissioning, the water supply shall be flushed and sanitized in accordance with the "Manual on Control of Decontamination of Household Drinking Water for Disinfection of Water Supply Facilities with Chlorine at Centralized and Local Water Supply," with the preparation of a special act.

Sanitary treatment is performed by the customer (contractor) at his own expense or Mosvodokanal at the expense of these organizations.

The Contractor is responsible for the development of the basic flushing scheme and the project for the construction of the water pipeline.

The water metering unit is accepted according to the album PP 1616 of Mosproekt JSC. Water metering inserts - according to the album PP1618 JSC "Mosproject."

When selecting plumbing appliances and fittings, the customer should provide for the installation of water-saving plumbing fittings in accordance with Appendix No. 3 to the Order of the Prime Minister of the Moscow Government dated 05.05.97 No. 460RP.
