1. LOCATION WWTP CETINJE

According to the adopted regulations plans, location of the future waste water treatment plant for the Royal Capital Cetinje is located on a site near the village Dobrsko selo. WWTP occupies a rectangular shape of the total area 7.944,0 m, and enclosed area 6.600 m (or 66 acres). This area will be located at ground level, leveled approximately 530,00 masl, while the current field is in a range of small slope between elevation 542,00 to 526,60 masl. To WWTP location can be reached by turning from the highway Podgorica-Cetinje, which leads next to Belveder restaurant and come down on the macadam road which will be reconstructed for the needs of the plant. This road would later serve as a service road to serving this plant.

Location of the future WWTP extends on a total of 12 land parcels, some of them are fully engaged and some of them are partially engaged, which is shown in detail in previous expropriation study.

PICTURE 2 ACCESS ROAD




2. HYDROTECHNICAL SOLUTION

Waste water gravity comes to the location of the WWTP by fecal sewer 400. Because of the difference in altitude from exit of collector of the future tunnel Belveder to location of the plant, we provide larger number of manholes with cascades so that water leads to manhole with flow meter at low pressure from a few meters, so that this flow meter can work with full profile. After leaving this manhole, the water enters in the separating chamber from where water distributed on two lines with 50% capacity (55 l/sec) to a screens and grit and grease chamber. Also, lateral is designed safety overflow, which also represents the by-pass through whole plant. The dimension of this pipeline is 500 and through him all water amount leads to collecting manhole. In this manhole water is combined with purified water and that mix leads to manhole with exit flow meter, and then gravity, with free fall, goes to trapezoidal channel for large atmospherically water which goes to river Rijeka Crnojevia.

2.1. WASTE WATER LINE TREATMENT

From grit and grease chamber, water through pressure pipeline goes to equalization tanks where it is the accumulation done for equal supply to the SBR units. This unit works discontinuous, i.e. it has a period of charging and discharging, that difference in continuous flow and operating mode of SBR accepts equalization tanks. In the first phase is provide to be completed one units SBR, while in the final phase is provide two more.

Water supply to the SBR is done through the inlet pipeline 500, by which the water is distributed into one of six units of SBR (two units were merged into one building units). The entry in each unit is providing via penstock gate.

After water treatment in SBR, the water is collected in the collecting pipeline and then to a collecting manhole, from where water gravity goes to pumping station within command building. These pumps provide enough pressure for water filtration through sand filters (chosen filter type is one who work normally under pressure), after filters the water leads into the manhole with reducing-valve pressure and goes to manhole with exit flow meter. Situation with routes of external pipe connection have been given in the hydro-technical part of the project and in the appendix is given hydraulic profile of water and sludge line through the plant.

On the sludge line, from the SBR through pipeline 100 leads to thickener and filter presses.

2.2. PROTECTION LINE OF OVERFLOW WATER

Security overflow, by the separating chamber overflow which leads to by pass, is provided from the collecting basin.

Especially are given discharge for drainage water from certain object through special manhole discharged into treated waste water.

They are easy to install; They have more bandwidth for the same diameter pipeline; They are easy to transport and They are easy to make new connections.

The network is dimensioned so that the adopted slopes, fulfillments of cross section are not exceeding 50%.

All sewage water collects and drains to a separating chamber (object 5) and leads to a process of purification.

6. RAIN WATER SYSTEM

For drainage of storm water from the plant, is provided the system of open channel, which are placed parallel with internal road. It is planed that channel leads rain water from plant to river Rijeka Crnojevia. Authoritative rain for territory of the Municipality of Cetinje which are adopted during calculation are twenty minutes rains, t = 20 min, with return period of five years, T = 5 y, and amount i = 22.4 l/m2/20 min, or i = 0.01867 l/m2/s.

During the calculation are adopted basic parameters, such as runoff coefficient, which is for green areas = 0.35, and for roads and roofs of building is = 1.

6.1. CHANNEL DESCRIPTION

These channels installed at the plant for waste water treatment, used for collecting water from the roofs of buildings and land under roads and green areas.

The channels are placed at the edge of the plant and between object following the internal road, and they serve to protect WWTP from atmospheric water and evacuation of water from impermeable surfaces.

Channels are designed as a concrete channels, rectangular cross section, width and depth of 30cm or 40cm, depending of the amount of water which they should receive.

In section 1 4, the channel passes through internal road, so it is planed that on this part of road channel should be covered by grid resistant on heavy traffic.

7. SYSTEM OF FIRE PROTECTION

7.1. EXTERNAL AND INTERNAL HYDRANT NETWORK

For fire fighting of any fire on the building is provided the external and internal hydrant network. The external network is placed around the plant in a ring, pipe diameter 100, for operating pressures up to 10 bars, while for the internal of command building is designed hydrant, pipe diameter 50.

Fire fight hydrant network is connected to a city water supply network of city Cetinje, where is provided amount of 12 l/sec and minimum pressure of 4 bar.

The total amount of water needed for firefighting in the building, depending on the degree of resistance to fire and building categories according to the technological process of fire risk are given in the table.

Considering that the category of technological process in the facility K5, and the volume of the largest facility of up to 2.000 m3, and the fact that the degree of resistance to the fire building II, the amount of water needed for effective firefighting is 10 l/sec.

In our case, for turning off the fire, must be provide a minimum amount of water of 10 l/sec, which is required for simultaneous operation of external (5 l/sec) and internal (2 x 2,5 = 5 l/sec) hydrants network, or with two external hydrants.

7.1.1. EXTERNAL HYDRANT NETWORKS

External hydrant network is providing in the form of a ring system of pipelines.

The largest distance between the external hydrants is 80 m, with a fact that the fire in a building can be put out with the outer two hydrants simultaneously.

The distance from hydrants to building wall is at minimum 5 m.




Around the building are placed underground hydrants.

Hydrants diameter is 80.

Pipe of distribution pipelines in network of pipes and hydrants for each hydrant have a diameter not less than 100.

Minimum work pressure at external hydrant should be 2.5 bars.

7.1.2. INTERNAL HYDRANT NETWORKS

For fire fighting in enclosed building, areas over 150 m2, is planed internal hydrant network, which are powered by external hydrant network.

Pressure at the most unfavorable hydrant is no less than 2.5 bars.

For inside hydrant network is provide minimum inner pipe diameter 52mm, and hydrant connector smallest inner diameter 52mm, type C, according to JUS M.B6. 673.

Distance between hydrants is such that the entire aria which will be protected by covering with jet water, with certain allowances for the fact that length of hose is 15m, and length of compact jet is 5m.

In fire cabinets set is putted a fire hose with normal diameter of 52mm, with a nozzle diameter of 12mm.

Internal hydrant network in the building is set up so that it is possible to protect all areas of fire.

7.2. HYDRAULIC CALCULATION

Hydraulic calculation of hydrants network are done for the case when two farthest external hydrants works, and in this case there are hydrants PH2 and PH3. Pressure which will be provided from city network of Cetinje on inlet 150 in junction where located flow meter at the entrance on the plant is is 4.0 bars. Considering that the minimum pressure at external hydrant is 2.5 bars, that losses in network should not exceed 1.5 bars.

From the hydraulic calculation (given in table 7.2) that show that the losses in the ring hydrant networks are almost negligible, so it can be concluded from the fact that the hydrants will work smoothly.
