4.4.1 Provision of private fire hydrant
a. General
Every part of a fire engine accessway and/ or fire engine access road shall be within an unobstructed distance of 50m from a fire hydrant. Where a public fire hydrant conforming to this requirement is not available, private fire hydrant(s) shall be provided. See Diagram 4.4.1a..

Clause 4.4.1a. : Provision of private hydrant
Figure 4.4.1a.
The distance of 50m is measured horizontally along the fire engine accessway.
b. Use of public fire hydrant
Existing public fire hydrants along one side of a public road shall not be designated to serve developments sited on the other side of the public road, except for a road having at most two lanes, regardless of traffic direction.
c. Locations of fire hydrants
In situations where more than one private fire hydrants is required, the fire hydrants shall be located along the fire engine accessway/ fire engine access road such that every part of the fire engine accessway/ fire engine access road is within an unobstructed
distance of 50m from any fire hydrant. See Diagram 4.4.1c..
R
Rationale - Clause 4.4.1b
Public roads with multiple lanes will likely have high volume of traffic. In the event where only one fire hydrant exists on the opposite side of the road, the traffic would be affected when firefighters utilise the hydrant. This will create congestion or result in road closure, thus disrupting the traffic flow.

Explanations & Illustrations
Clause 4.4.1b. : Provision of private hydrant
Figure 4.4.1b.
All developments shall be provided with its own private hydrant. In the case of a new development where the existing public hydrant is within the stipulated coverage, such hydrant can be considered. To qualify for the relaxation, the existing public hydrant shall be within an unobstructed distance of 50m to every part of a fire engine access road and/or fire engine accessway.
If the existing public hydrant is sited across the other side of the public road, the said public hydrant is not allowed to serve the development if the public road is more than 2 lanes, regardless of direction of traffic flow.
d. Siting and types of fire hydrants
Siting and types of fire hydrants shall comply with the requirements stated in SS 575.

Clause 4.4.1d. : Provision of private fire hydrant
Figure 4.4.1d. - 1
Hydrant H1 is not required if the adjoining land is maintained as open space. However, if the land is later developed for new buildings or usages, provision of hydrant would be required.
Section
Figure 4.4.1d. - 2
The minimum 1000mm clearance between the building or retaining wall/boundary wall and fire hydrant is to allow the minimum working space for hose connection.

e. Ringed fire hydrant pipes
For a building that is required to have an island site fire engine accessway the fire hydrant pipe shall be a ring system. Isolation valves shall be provided on the fire hydrant ring such that on any section of ring, not more than one fire hydrant can be isolated when required for maintenance without affecting the water supply (both designed pressure and flow) to the other fire hydrants on the ring.

Explanations & Illustrations
Clause 4.4.1e. : Provision of private fire hydrant
( No illustration )
Where the building is provided with island site fire engine accessway, the hydrant pipe serving hydrants within development shall be a ringed water supply system. This system to hydrant will ensure uninterrupted water supply to facilitate firefighting operation during a fire emergency. Isolation valves shall be provided at strategic locations such that any section of the ring (only one fire hydrant) scheduled for maintenance or repair shall not affect the water supply (pressure and flow) to other connected private hydrants. The hydrant ring pipe should be run above-ground or laid beneath earth. Where it is not practical (e.g. at road crossing), the section of underground hydrant pipe shall be appropriately supported to prevent any pipe leakage due to movements of vehicles above. Additional isolation valves should be provided at pipe sections just before and after the road crossing.

4.4.2 Water supply for private fire hydrant
The provision of water supply for a private fire hydrant system, where required by this Code, shall comply with the following requirements:
a. Private fire hydrant at or below reduced level 125m
(1) Private fire hydrants installed at reduced level 125m and below can receive direct supply from public water mains provided the flow and pressure from the public water mains meet the fire hydrant requirements as shown in Table 4.4A
, or the following requirements are complied with:
(a) the AFA of the largest compartment shall not exceed 1000m2 for PG III, IV, V & VII and not exceed 500m2 for PG VI & VIII buildings. No AFA limit for covered car park in PG II, III, IV, V & VII buildings;
(b) the nominal bore of the fire hydrant pipe and the bulk water meter shall not be less than 150mm in diameter; and
(c) the running pressure/flow at the hydraulically most unfavourable fire hydrant of the private fire hydrant system shall comply with the following:
(i) running pressure >= 0.9 x (running pressure of the nearest public fire hydrant – pressure drop across the bulk water metre); and
(ii) flow rate >= 0.9 x water flow of the nearest public fire hydrant or >= total flow
demand (as required in
Table 4.4A
) of the private fire hydrant system, provided the running pressure at the most remote private fire hydrant is greater than 2 bars.
Note:
In calculating the frictional loss for the private fire hydrant system, the design flow rates shown in
Table 4.4A
shall be used. The pressure drop across bulk water metre shall not be more than 1 bar.
(2) If the requirements stipulated in Cl.4.4.2a.(1) cannot be met, a storage tank of sufficient capacity meeting the flow rate and duration as specified in
Table 4.4A
with the requisite pumping facilities shall be provided.
Effective Date: 1 Sep 2021
E
Explanations & Illustrations
Clause 4.4.2a. : Water supply for private fire hydrant
Figure 4.4.2a.
There is a need to differentiate at RL 125m as public mains located at above RL 125m would not be able to provide the required water pressure. It is important that
hydrants annotated in building plan should be given their respective reduced levels.
a. Private hydrants that are sited at RL<125m are allowed to take the water supply from public water mains, which likewise should not be located above RL 125m.
b. There is a need to observe the RL<125m as the public water mains located at above RL 125m would not be able to provide the required pressure and flow rate for firefighting purposes.
It is therefore important that private hydrants and the supply public water mains annotated in building plans should be given their respective reduced levels.
Allowable losses in hydrant pipe
(Using Hazen-William’s formula)
P = [6.05 x Q1.85 x 107] / [C1.85 x d4.87]
Example :
Q = 27 L/s = 1620 L/min
d = 150mm = 0.15m
C = 140
P = 0.14173 kPa/m
Pressure after bulk meter (P1) = 300 kPa
Length of hydrant pipe = 180m
Number of bends = 4 nos.
Equivalent length of bends = 30m
Total equivalent length = 210m
Pressure loss in pipe = 29.76296 kPa
Pressure available at remote hydrant (P2) = 270.237 kPa
% loss in pressure = 0.90079 (Not < 90%)

The hydrants are required to be charged with water all the times so that firefighters could use them for feeding the breeching inlets and for firefighting purposes.
(2) The private fire hydrant can be in the form of a dry fire hydrant, if it is not the sole fire hydrant within 50m from any breeching inlet(s) feeding firefighting systems for the building(s) within the plot of land, which include:
(a) automatic fire sprinkler systems, or
(b) dry riser systems, or
(c) wet riser systems.
(3) A dry fire hydrant shall comply with all of the following requirements:
(a) A dry private fire hydrant shall be connected to a 150mm diameter dry pipe, which shall be connected at the other end to a four-way breeching inlet.
(b) This breeching inlet shall be within 18m from any fire engine accessway/fire engine access road having minimum 4m width and within 50m from any wet fire hydrant, private or public.
(c) The private dry pillar shall be painted in “yellow” and labelled “dry” on the fire hydrant pillar.
(d) A signage indicating the location of breeching inlet shall be positioned next to the dry private fire hydrant.
c. Water supply and storage requirement
Where more than one private fire hydrant is located above reduced level 125m within the same plot, storage and pumping arrangements of water supply to these specified fire hydrants shall comply with those for wet rising mains stipulated in SS 575 and

Figure 4.4.2b.(2)
“Dry” hydrant is equivalent to the provision of dry rising main. Care should be taken to prevent accidental damage by vehicle etc. to the horizontal run of the pipe aboveground.
The dry pipe should be differently identified on site. The provision of dry hydrant is a relaxation as all hydrants are required to be fed with water at all times. This is allowed as the firefighters could use other hydrants located below RL 125 which are within 50m from the breeching inlets.
