Manholes are to be constructed of the following materials:

Precast concrete manholes shall only be provided where the water table is low. The

precast wall units shall be provided with rubber sealing ring gaskets between units,

specific approval of Irish Water, complete with a 150mm minimum thickness cast in

situ concrete surround, C16/20, in accordance with IS EN 206, 20mm aggregate

size, in accordance with IS EN 12620. The precast concrete manhole shall have

either pre-cast or cast in-situ concrete base (225mm minimum thickness beneath

channel) and pre-cast or cast in-situ concrete roof slab (225mm minimum

thickness), both constructed of C30/37 concrete, in accordance with IS EN 206,

20mm aggregate size, in accordance with IS EN 12620, reinforced with high tensile

steel bar reinforcement, with a minimum 40mm concrete cover. The concrete

surround to the precast concrete wall units shall only be omitted if the manhole ring

has a wall thickness of 125mm or more and where a proprietary watertight sealing

system is provided as an integral part of the manhole wall system.

Manhole Bases should be constructed of cast in situ C30/37 concrete, in accordance

with IS EN 206, 20mm aggregate size, in accordance with IS EN 12620, with a

minimum thickness of 225mm. Thicker manhole bases are required for Sewers in

excess of 3m deep or where the manhole size is greater than the standard minimum

size outlined above. Alternatively, approved precast concrete bases may be used,

incorporating channels, benching, etc. subject to Irish Water approval and compliance

with BS 5911, Part 4. Where precast concrete rings are used with cast-in-situ concrete

bases, the bottom ring unit shall be cast into the base slab to ensure adequate sealing

of the wall/base junction

Manhole Covers and Frames shall comply with IS EN 124 and BS 7903 and be of

suitable load grade, Class D400 (or E600 for heavy trafficked roads, as required on a

case by case assessment basis). Covers shall be selected and designed to prevent the

cover unit(s) falling into the chamber. Covers and frames shall be designed to be safely

lifted with minimal risk of manual handling injury, suitable for use with lifting equipment

and arranged to ensure rescue procedures are not impeded. Frames should be square

or circular with a square or circular insert with a minimum clear diameter/dimension of

600mm. Class D400 shall either have a 100mm or a 150mm deep frame and Class

E600 covers on heavily trafficked roads shall have a 150mm deep frame. All covers

shall be of non-rock design and two closed keyways shall be provided in each cover.

Manhole covers may be single units or double triangular. Third Party Certification shall

be provided for all cast iron manhole covers and frames.

Thermoplastic Structured Wall Pipes; Thermoplastic structured wall pipes shall

comply with the provisions of IS EN 13476 (2007/2009). Pipes to be of Stiffness

Class 8kN/m2 and to be capable of demonstrating a jetting

resistance of 2,600 psi (180 Bar) without damage when tested in accordance with

Section 3.3 of WIS 4-35-01 (2008). (Sewer diameters 150mm up to 450mm,

Service Connections of 100mm diameter);

Unplasticised PVC; Unplasticised PVC pipes and fittings shall comply with the

Stiffness Class 8kN/m2. Provision for jetting shall be based on the WRc

Sewer Jetting Code of Practice, June 1997. Pipes to be capable of resisting a

maximum jetting pump pressure of 2,600psi (180 Bar) without damage.

(Sewer diameters 150mm up to 450mm, Service Connections of 100mm

diameter);

Other; The use of alternative pipe types and materials will require the prior written

agreement of Irish Water
