Water supply

The district center is provided with drinking water from the existing seven underground water intakes. The quality of water in the water supply network supplied to the population according to sanitary-chemical and microbiological indicators according to SanPiNu 2.1.4.55996 corresponds to "Drinking water." Over the past 5 years, due to the growth of the district center, there has been an increasing shortage of drinking water. In this regard, the design and estimate documentation "Increase in water supply r.z. Muslyumovo from the spring at n. Tashliyar. " The quality of spring water in all respects exceeds the water from the existing water intakes. In 2004, construction and installation work was carried out at this facility in the amount of 3000.0 thousand rubles.

Heat and power supply of the district center

As of 01.01.2005, heat supply to the population living in the houses of the municipal housing stock of the district is carried out from heat supply systems owned by the state.

1. The total capacity of boiler houses is 30.5 Gcal/hour.

2. The length of heat networks in two-tube terms is 44 km.

3. 9 boiler houses operate on gaseous fuel.

4. There are 2 fireplaces operating on electric heating.

Heat supply of residential buildings and social facilities (except for the private sector and several State institutions) is made from 9 centralized boiler houses. 8 of them work on gas fuel, 1 on fuel oil - a public bath with 28 seats.

Since 2002, in order to save energy costs, the Muslyumov WFP Housing and Communal Services has been systematically working on the reconstruction of boiler houses and the entire heat supply system. In 2004, for these purposes, from all sources of funding, work was carried out on the reconstruction of the boiler house in the amount of 3500 thousand rubles and on the reconstruction of heating networks in the amount of 1300.00 thousand rubles.

Disposal of household waste

The population is provided with a landfill for the disposal of solid household waste, but there is no separate waste collection system. A separate waste collection system should be developed. In 2003, the construction of USC with sewer networks with a capacity of 700 m3/day began. Construction is scheduled for completion in the first quarter of 2006.

According to the results of previous years and the past year, some stabilization of the situation and the long-awaited positive trends in the field of housing and communal services can be noted.

The housing stock, which amounts to over 102 thousand square meters, is serviced by Muslyumovsky Engineering Networks OJSC, Polygon MSW Muslyumovo LLC, Zhilengoservis LLC, and the municipal institution Duslyk management company. A partnership of homeowners "Uyut" has been created. This company is engaged in the maintenance of houses, ongoing repair of buildings, internal engineering networks, and manages housing stock. The collection of payments has increased to 96%, but this does not suit us. Payments must be collected in full every month, it is impossible to allow homeowners to accumulate debts, which will subsequently place a heavy burden on their shoulders.

So far, the cost of heat services remains high, which in the total set of services is 56% or 23 rubles 14 kopecks per 1 square meters. meter. In order to reduce tariffs for thermal energy at the expense of own and leasing funds of OJSC Muslyumov Engineering Networks, a boiler house with thermal networks is being reconstructed. The project cost of this program is 26 million rubles, it involves the preservation of three boiler houses, instead of 10 boilers, 2 boilers with a total capacity of 4.4 megowatts will operate. The boiler room is fully automated. Within the framework of this project, 2.6 km of heating mains were laid using energy-saving technology, a total of 4 km of heating mains will be replaced.

At the expense of the company's own funds, water supply with a length of 1000 m for 670 thousand rubles was carried out, the first and second water intakes were fenced. 1 million 270 thousand rubles were spent on repair and construction in the water supply industry.

By the forces of the Muslyumovsky RES in 2007 in caps. repair and construction of electric facilities of the district was completed in the amount of 25 million rubles and under the Program for the transfer of housing to apartment heating systems, four apartment buildings in the district center were transferred to apartment heating with the installation of 2 circuit boilers, and therefore the costs of residents for heating were much reduced .

In 2007, the law "On the Fund for the Reform of Housing and Communal Services" was issued. Pursuant to the law, the following has been implemented :

- Developed targeted program for 20082011 years for the overhaul of apartment buildings;

- All 12 conditions for financial support from the Fund have been met;
