CONNECTION TO FOUL WATER SEWERS AND THE CONSTRUCTION OF LATERAL DRAINS

2.   Connection to foul water sewer

Where a connection is required to be made to a foul water sewer such connection shall be made as follows—

  1.  

    (1)   where the connection is to be made—

    1.  

      (a)     directly into a manhole without a drop connection the stopper of any conveniently situated joinder junction shall be cut away and the spigot of the first of the connecting pipes shall be jointed to the junction using a double collar if necessary: Provided always that if a joinder junction is not conveniently situated a neat hole shall be cut in the walls of the manhole such that the crown of the connecting pipe is level with the crown of the foul water sewer and the first of the connecting pipes shall be built into the manhole wall with its spigot flush with the inside face of the wall and the connection shall be continued and haunched inside the manhole as hereinafter described in regulation 14 of these Regulations;

    1.  

      (b)     into a manhole which has been provided with a drop connection the stoppers of the 2 joinder junctions provided shall be cut away and—

      1.  

        (i)     a rest bend shall be jointed to the lower junction and a tumbling bay junction shall be jointed to the upper junction and a vertical pipe shall connect the rest bend to the tumbling bay junction, and the rest bend, tumbling bay junction and vertical pipe shall be surrounded with concrete 6 inches thick, or

      1.  

        (ii)     a small chamber of internal dimensions of one foot cube shall be built against the lower of the 2 junctions in concrete with one face made monolithic with the wall of the manhole and a vertical pipe built into the roof of the chamber such vertical pipe being extended to and jointed with a square junction jointed to the upper junction, the vertical pipe and square junction being surrounded with concrete 6 inches in thickness and monolithic with the wall of the manhole;

    1.  

      (c)     to a square junction left for that purpose on a sewer—

      1.  

        (i)     the concrete surround to the junction shall be cleaned and the temporary stopper shall be carefully removed,

      1.  

        (ii)     a short length of concrete pipe not less than 12 inches in diameter shall be cut and connected in a watertight manner with 2 6-inch diameter pipes suitably inclined and approximately diametrically opposite to one another and the concrete pipe shall then be laid on a bed of mortar over the open vertical pipe of the junction, and any inside projection on to the junction shall be sloped up to the wall of the pipe with mortar, and

      1.  

        (iii)     the open end of the concrete pipe shall be sealed in a watertight manner and this improvised “Y” junction shall be surrounded with and covered with concrete 6 inches in thickness and monolithic with the concrete, if any, of the sewer: Provided always that a purpose made “Y” junction sealed at one end may be used in place of the improvised junction.

  1.  

    (2)   No connection shall be made on a sewer when no square junction has been left for that purpose unless the Sewerage Authority is satisfied that the watertightness of the sewer will not be prejudiced by the connection in which case sufficient pipes may be cut out of the sewer to permit of the interpolation and jointing in the sewer of a suitable junction.

3.   Lateral Drain

The open end of the pipe or pipes forming a connection to a foul water sewer shall be jointed to a line of pipes laid in a manner similar to that hereinafter described for drains and extending to a lateral drain manhole constructed in a manner hereinafter described in a suitable position, generally near the boundary of the road opposite, to the point of connection to the foul water sewer, and such manhole shall be provided with a sufficient number of joinder junctions effectually to connect to all drains likely to be laid in the vicinity and the lateral drain shall be extended from this manhole in a direction parallel with that of the sewer to a position capable of receiving the drain from the most remote building likely to drain into that lateral drain. The lateral drain shall terminate with a bend to facilitate the entry of the furthermost drain and it shall be provided with suitable junctions or joinder junctions to permit of other drains or anticipated future drains connecting therewith. Watertight seals shall be provided to all pipes and junctions not immediately to be connected to drains.

PART 3
DRAINAGE

4.   Layout of System of Drainage

  1.  

    (1)   Where the system of drainage is to connect to a lateral drain or to a septic tank or, in the case of surface water, where it is to connect to a watercourse or soakaway the drain shall be laid from the point of connection in a straight line to a manhole near the building and within its curtilage located conveniently for the reception of soil and waste water or for the reception of surface water and the drain shall continue beyond such manhole in a straight line to any further manhole or manholes which may be necessary effectively to receive from the building and its curtilage the whole of the soil and waste water or the whole of the surface water not required to be stored for use. Where the system is for the drainage of foul water, provision must be made as hereinafter specified for the ventilation of the drain at or near the end or ends remote from the lower end of the drain.

  1.  

    (2)   Where the system is to connect to a lateral drain which has no convenient junction already provided a manhole must be provided on the lateral drain at the point of connection to the drain.

  1.  

    (3)   Where the site coverage is such that the owner's outfall manhole cannot conveniently be within the curtilage of his or her property the Sewerage Authority may agree to the construction of this manhole within the public space.

  1.  

    (4)   No connections shall be made between systems of drainage dealing with foul water and systems of drainage dealing with surface water.

  1.  

    (5)   When the dual system of drainage is adopted:

    1.  

      (a)     the soil shall generally enter the drain, if above the ground floor by soil pipes and if at the ground floor by drains both connected directly to the nearest suitable manhole;

    1.  

      (b)     waste water shall generally enter the drain if above the ground floor by waste pipes and or waste water pipes discharging into collecting heads on waste water pipes, or connected directly to waste water pipes which discharge over or into gully traps connected to the drain and if at ground floor by discharging over or into gully traps, and thence by pipes connected directly to the nearest suitable manhole;

    1.  

      (c)     surface water from above ground floor shall by a suitable arrangement of rain water pipes, be discharged into open channels connecting to road drains or soakaways. No open channels will be permitted to cross public footpaths. Such crossings must be piped and the pipes laid at sufficient depth to allow the footpath surfacing to be carried over the pipe.

  1.  

    (6)   Where the one pipe system of drainage is adopted:

    1.  

      (a)     soil and waste water shall generally discharge into the soil pipe if the connection is 12 inches or more above the invert of the connecting drain below ground level, and if not, soil shall discharge directly into the drain and waste water indirectly into the drain by discharging over and into gully traps connected to the drain;

    1.  

      (b)     the destruction of the water seal of fittings required to be trapped as hereinafter specified, shall be guarded against by the use of approved deep seal traps. A trap having a water seal of not less than 3 inches shall be deemed to be a deep seal trap for the purpose of this Act.

  1.  

    (7)   No waste water pipe, soil pipe or ventilating pipe shall be trapped but all waste pipes connecting thereto shall be trapped effectually at the sanitary fitting by a trap so constructed as to be capable of maintaining a sufficient water seal.

  1.  

    (8)   Every branch drain shall at the point of junction join a main drain obliquely in the direction of the flow of such drain and all bends and turns shall be truly curved and any alteration in the size of the pipe shall be properly tapered and of good shape. Junctions shall wherever practicable be crown to crown.

5.   Construction of Drainage Works

Drains shall consist of pipes and channels laid true to line and levels and provided with all necessary bends, tapers and junctions to permit of the contents flowing at a self-cleansing velocity without settlement or scour to the outfall. The pipes shall be watertight and where they pass under a building they shall be of cast iron or shall be surrounded with concrete 6 inches in thickness save that where any pipe passes through any wall or beam it shall be protected against any settlement of such wall or beam by being separated therefrom with a gap of 3 inches which gap shall be unoccupied or shall be closed with a material which is incapable of transmitting an excessive load.
