PART II: CONSTRUCTION OF SEWAGE SYSTEMS
1. Materials used for sewage works
(1) To substantiate their choice of materials, the designer of the sewage system shall submit a
technico-economic analysis for at least two types of materials that are to be used. This technicoeconomic analysis shall focus on the following aspects: durability, investment costs, operating costs,
operational safety and estimated number of failures over time, as well as the duration of the repair
periods.
(2) The materials used to build the structures and installations pertaining to a sewage system
must meet certain general criteria, depending, of course, on the role and importance of the respective
structure or installation, its intended use, whether it is of a temporary or permanent nature, etc.
(3) Since the utilisation of the materials is generally conditioned by the presence of
wastewater, they must meet the following criteria:
a) resist the corrosive and hydrating action of water;
b) provide a very good level of waterproofing to the elements in which they are used and
avoid exfiltrations and/or infiltrations;
c) have the mechanical strength required by the intended use;
d) have a low level of roughness, in order to limit the distributed load losses;
e) have the highest level of reliability possible, which should normally exceed the rated
period of service (in accordance with the legal regulations in force with regard to the
depreciation of fixed capital in tangible and intangible assets, relating to these periods);
f) resist the action of various external factors according to their intended use (water and air
temperature, interior and exterior mechanical stresses, the aggressive action of the ground,
vagabond currents, etc.) and not undergo permanent deformation under their action;
g) not dissolve when in contact with wastewater or silt, and not be harmful to the
microorganisms used to purify the water;
h) not pose any kind of hazard for the people that they come into contact with, who handle
and use them;
i) have low costs;
j) not require high investment and operating costs;
k) be easy to use, store and handle;
l) enable their quick installation and removal (for pipes, special parts, reinforcements, etc.);
m) allow for waterproof jointing (for pipes, for example);
n) resist humidity, temperature and freeze-thaw variations, if working in environments and
fields of activity where such variations may occur;
o) comply with the requirements of the beneficiaries, the specifications drawn up by the
design engineers and the preparation recipes specified by the design engineer and used by
the contractor (for concrete, mortar, plaster, etc.);
p) have a volume, weight and size that enable their transportation on public roads;
q) retain their qualities, characteristics and properties when stored in suitable conditions
during the guarantee period specified by the manufacturer;
r) have qualified personnel available for their execution and operation;
s) the building materials/products must comply with the specific regulation in force with
regard to placing building products on the market;
(3) The range of materials needed to construct the sewage systems is very varied, depending
on the circumstances in which the latter are to be used. Therefore, the various building materials and
installations can be used to:
a) carry liquids (wastewater, silts of different moisture levels, reagent solutions, etc.) in
pressurised pipes or free-level conduits;
b) for pumping installations (suction and discharge pipes, special parts, reinforcements, etc.);
c) build structures of brick, plain concrete, reinforced concrete, prestressed concrete, etc.;
d) waterproofing.
(4) The materials that are frequently used to construct sewage systems are as follows:
a)
b)
c)
d)
sand, gravel, cement, water and additives for the preparation of mortar and concrete;
hot rolled reinforcing steel and welded mesh panels;
rubber, asphalt board, plastic sheets, epoxy resins, etc. for waterproofing and protection;
steel, cast iron, polyethylene, polypropylene, fibreglass reinforced polyester (FRP), pipes
made of centrifugally cast reinforced concrete (PREMO pipes), PVC, stainless steel, etc.
for pipes, conduits, prefabricated inspection chambers, tanks for small pumping
installations and compact water treatment installations, etc.
(5) Given the lack of operational data on the behaviour over time of the plastic materials used
to construct the sewage systems, the quality of these plastic materials must be guaranteed. Therefore,
the supplier of pipes, conduits, prefabricated inspection chambers, tanks, etc. made of plastic
materials shall have to submit test certificates in accordance with the legislation in force.
(6) Also, in light of the negative experiences when using prestressed reinforced concrete pipes
(tolerances which vary from one manufacturer to another, poor quality, non-compliance with the
requirements for resistance to the chemical action of wastewater carried through these pipes), all
pipes must be pressure tested, one at a time, on a test bench at the manufacturing plant and in the
presence of the beneficiary. This helps prevent any additional costs that may arise due to the need to
replace those pipes that fail the on-site pressure test.
2. Construction of sewage works
2.1. General considerations with regard to the way in which the construction of
sewage works is organised
(1) The method for organising the construction of sewage works includes the set of measures
for ensuring that they are build in accordance with the corresponding designs, within the limits of the
scheduled values and deadlines.
(2) The main objectives that the contractor should set to ensure that the execution of the works
is organised rationally are to:
a)
b)
c)
d)
e)
f)
complete the works by the deadlines stipulated in the schedule;
improve the quality of the works;
not exceed the building costs stipulated in the quote;
reduce the completion deadline period;
increase work productivity and the degree of utilisation of the equipment;
adopt construction technologies with a maximum percentage of mechanisation.
2.2. On-site layout of the works and route preparation
2.2.1. The conduit route shall be laid out by taking into account the following:
a) provisions stipulated in the technical documentation (detailed engineering design);
b) levelling of the permanent markers, carried out with the accuracy stipulated in the design;
c) installation of temporary markers along the route, for construction purposes, connected to
the permanent markers;
d) materialisation of the plotting axes and angles, fixed and linked to permanent objects
present on site (buildings, structures, etc.) or the pillars installed, for this purpose, along
the route;
e) points of intersection between the conduit route and the routes of the existing underground
systems and structures, which shall be marked on the ground using special signs.
2.2.2. Taking up the paving
Paving shall be taken up over an area that is wide enough to enable work to be carried out in
accordance with the provisions stipulated in the design. The materials resulting from taking up the
paving shall be stored on the pavements or on the side of the trench, leaving room on the other side
for the excavated soil.
2.2.3. Carrying out the excavation works
(1) Excavation works for trenches and foundation holes shall be carried out in accordance
with the provisions stipulated in the design. These works must always be carried out from an
upstream to downstream direction. The excavation methods used shall be determined by the volume
of work, the characteristics of the soil, as well as the depth and shape of the trenches. The trenches for
laying out the conduits shall have vertical or sloping walls, depending on the nature of the soil and the
space available for excavation.
(2) The excavated soil shall be stored on one side only, leaving a safety margin of 50 cm. The
excavation shall be deepened near the pipe joints, as applicable, to leave room to waterproof the joint
and avoid supporting the pipe solely on the sleeves.
Throughout the entire duration of the works, any excess soil can be stored on the side of the trench, to
enable access of ambulances and fire engines, as applicable.
(3) Access bridges (walking boards) equipped with protection handrails shall be installed over
the trench, 30-50 m apart, to enable pedestrian circulation.
(4) The way in which the excavated soil is stored along the trench shall also make sure that
rainwater can drain away so that the excavation site or neighbouring terrain does not flood.
2.2.4. Trench shoring
(1) Trenches with vertical walls shall be excavated by bracing their walls. For excavation
depths which exceed 5.0 m, the trench shall be braced on the basis of a shoring design.
(2) The banks of the trench shall be supported on fir wood planks and piles or metallic support
elements, to enable a sufficient level of safety for the installation works and allow for all works inside
the trench to be carried out easily.
2.2.5. Dewatering
(1) The issue of discharging any groundwater from the excavation can be a decisive factor in
choosing the method for carrying out the sewage works and selecting adequate materials to ensure
that the works are of a suitable quality.
(2) The main factors which determine the methods and means used to discharge water from
excavations are the:
a) volume of water infiltrated;
b) maximum elevation level of the underground water from the excavation floor.
(3) The methods used to discharge water from excavations shall also take into consideration
the consistency and permeability of the ground where the excavation was made.
If there is a danger of fine materials being displaced, the drilled well filtration method or the method
of chambers exhausted by needle-shaped filter sets.
(4) Filtration wells are usually made by inserting casings with a depth of 7-20 m and Φ 300600 mm, with a second casing with the dimensions of Φ 100-150 mm installed inside it. Before
beginning to dig a trench, drilled wells shall be made on its sides, usually 3-7 m apart, according to a
chessboard layout. If the maximum hydrodynamic level is no deeper than 6-7 m, the water can be
extracted using horizontal-axis pumps, via a suction basket; for depths that exceed 6-7 m, the water
shall be extracted using submersible pumps.
(5) The needle-shaped filter unit shall mainly consist of:
a) two special self-priming pumps which pump the water and the air from the soil pores
simultaneously;
b) a metallic collector to which the needle-shaped filters are to be connected using flexible
rubber sleeves;
c) the actual needle-shaped filters shall be made of vertical metallic piping of 1 m in length
and 50 mm in diameter, threaded together to form pipes of the required thrust depth.
2.2.6. Pipe routing and construction of collectors
(1) The methods used to install prefabricated pipes shall be chosen according to the size and
weight of the pipes. Before inserting pipes in the trenches, the excavation floor shall be inspected and
corrected, as applicable. Lightweight pipes shall be lowered into the trenches manually; when the
pipes are heavier, differential hoist tripods or mobile wheeled/crawler cranes shall be used.
(2) Once the pipes have been lowered into the trenches, they shall be connected one after
another and shall be waterproofed in an appropriate manner. The pipes shall be installed on a sand
bed prepared in accordance with the specifications.
(3) When laying down the pipes at various depths, one shall comply with the indications
provided by the design engineer (on the basis of statistical calculations) and the manufacturer of the
material.
2.2.7. Carrying out refilling works
(1) The trenches shall be refilled with the excavated soil, following a levelling inspection and
after a quality inspection of the works has been carried out. The pipes shall only be covered with
loose, potentially sieved, soil, removing any large boulders and any scraps of concrete or other rough
materials. The loose soil shall be laid in layers, which must be compacted individually with great
care.
(2) The refilling works shall be carried out manually, in 10-15 cm layers for the first 0.30 m
above the pipe. Each layer shall be compacted individually, using a hand mallet or a "frog" mallet.
The remaining soil shall be laid in 20-20 cm thick layers, also well compacted, until the ground level
is reached, making sure to achieve a degree of Proctor compaction of at least 97%, in accordance with
the legal technical provisions in force.
(3) It is prohibited to bury in the filler soil any wood from forms, supporting elements, etc.
3. Construction of the water treatment works
3.1. Organisational works
(1) These are preliminary works carried out before the actual construction works, and are
intended to provide the conditions required to ensure that the latter can be carried out efficiently and
are of a suitable quality. The main elements of the organisation process are:
a) preparing the ground;
b)
c)
d)
e)
f)
g)
identifying the existing underground installations;
marking and delimiting the area that will be occupied by the construction site;
creating access routes for equipment and means of transport;
inspecting the materials and work equipment;
providing health and safety, as well as fire prevention equipment;
providing the necessary utilities (water, electricity, etc.).
3.2. Preparation of the ground for building the water treatment plant
(1) Before bringing any equipment onto the working face, a ground exploration survey must
be conducted with regard to the following:
a) category of ground to be excavated;
b) identification of any underground water, gas, oil, electricity or telephone networks, etc.;
c) the dimensions of the excavation to be made (depth, the lateral clearance for storing the
excavated soil);
d) access route for equipment and means of transport;
e) conditions to ensure rainwater drainage;
f) cutting down trees and clearing shrubs;
g) presence of overhead electricity lines within the excavation area.
3.3. Plotting the position of the water treatment plant
(1) The position of the plant shall be determined by carrying out plotting operations, which
must set the position of the future plant and the connections for domestic wastewater intake pipes and
purified water outlet pipes, as well as gas, electricity and drinking water systems, etc.
3.4. Carrying out building works for the water treatment plant
(1) The following shall be taken into consideration when carrying out foundation excavations:
a) to preserve the natural balance of the ground around the foundation hole after starting the
excavation works;
b) in moisture-sensitive soils, when the concrete is not poured straightaway, the excavation
shall stop 20-30 cm above the final elevation level.
c) The excavations shall require shoring depending on the:
d) depth of the excavation;
e) nature, homogeneity, stratification and cohesion of the soil, the presence of underground
water, etc.
(2) Within the same enclosure, the works with the deepest foundation shall be approached
during the initial stage, so that the foundation ground of any future neighbouring structures will not
be affected at a later date.
(3) The floor of very long excavations shall be sloping towards one or several points to ensure
that stormwater or infiltrated water is collected and discharged.
(4) Dewatering works must not cause scouring under the neighbouring structures in the area.
(5) To avoid subsequent deepening of the hole, which would change the foundation levels, a
levelling layer of concrete should be poured immediately on the excavation floor.
3.4.1 Excavations above the groundwater table
(1) Excavations with non-reinforced vertical walls can be made up to a depth of:
a) 0.75 m, for non-cohesive and/or weak cohesive soils;
b) 1.50 m, for cohesive soils with medium consistency;
c) 2.00 m, for highly cohesive soils located above the groundwater table.
(2) Excavations with reinforced vertical walls shall be used in the following situations:
a) the excavation depth exceeds the limit values obtained for excavations with nonreinforced vertical walls;
b) there is insufficient lateral clearance to make a sloping excavation;
c) when an economic calculation shows that a shored excavation is more advantageous than
a sloping excavation.
(3) The shoring system shall be chosen and its dimensions determined based on data obtained
from geotechnical and hydro-geological studies.
(4) Excavations with sloping walls can be made in any type of terrain, providing that the:
a)
b)
c)
d)
natural moisture of the soil is between 12-18%;
excavation is not left open for a long period of time;
maximum groundwater level is below the foundation elevation level;
gradient of the excavation slope does not exceed the maximum values given in Table 3.1:

where:
b - is the horizontal projection of the excavation slope;
h - is the excavation depth;
α - the angle between the excavation slope and the horizontal axis.
3.4.2 Excavations below the groundwater table
(1) For deep excavations made below the groundwater table, the water can be removed by:
a) direct dewatering, by collecting the infiltrated water in a sump and pumping it outside of
the foundation hole;
b) indirect dewatering, by using needle-shaped filters or drilled wells located around the
perimeter at distances obtained by calculation.
(2) The excavation walls can be reinforced with: steel sheet piles, waterproof barriers made of
concrete diaphragm walls poured in the ground.
(3) The following measures shall be taken when the excavation walls are reinforced with sheet
piles:
a) the sheet piles shall be permanently guided during their sinking in the ground;
b) the length of a sheet pile shall be equal to the depth of the excavation plus its receptacle.
(4) The sheet piles shall be sunk into non-cohesive soils by vibration and into cohesive soils
by hammering, or by using a combination of these two methods.
3.4.3 Direct dewatering
(1) As the digging level reaches below the groundwater table, the excavations shall be
protected using drainage ditch systems that harvest the water and guide it towards the collector wells
(sumps), where it is pumped out.
(2) An inverse filter shall be installed in the pump suction sump, around the suction basket, in
order to limit the influence that the suction process may have on the stability of the soil layers,
reducing the groundwater flow rate towards the sump below the limit flow rate that would displace
the fine particles in the composition of these layers.
(3) The ditches shall become deeper as the excavation progresses, and shall reach a depth of
0.4 - 0.8 m depending on the soil characteristics. The depth of the collector wells (sumps) shall be at
least 1.0 m below the elevation level of the excavation floor.
3.4.4 Indirect dewatering
(1) This is ensured using filtration wells or needle-shaped filters. These shall be installed
outside of the excavation perimeter, in one or several rows. They can temporarily reduce the level of
groundwater by 4-5 m during execution of the works. If the groundwater level needs to be reduced by
more than 4-5 m, the filters shall be installed in tiers and in a staggered formation split between two
or more fronts.
(2) Dewatering wells shall be made in bore holes with a diameter of 200-600 mm, in which a
metallic or plastic filtration manifold with a diameter of 150-200 mm, equipped with slots, is
launched. The filtration manifold shall be installed at depth, along the entire thickness of the aquifer
whose level needs to be reduced so that the structure can be built “dry”. Granular filtering material
shall be introduced between the working manifold and the slotted manifold (according to the inverse
filter rule), with sand towards the exterior and pure sifted gravel in the region of contact with the
slotted manifold.
(3) Needle-shaped filters are wells with a small diameter (Φ 7.5-10.0 cm), which are usually
sunk using a water jet. The filters shall be connected to vacuum pumping stations. Under normal
circumstances, depressions of 4-5 m can be achieved, for a filtration step, where the distance between
the filters is 1-5 m.
3.4.5 Refilling
(1) The ditches shall usually be refilled with soil from the excavation works. Slag, mining
residues, etc. can also be used for refilling, providing that the possibility of compaction and the
chemical action on the building elements that come into contact with the filler materials are studied in
advance.
3.4.6 Forms and supports
(1) The forms and supports for these special works shall comply with the provisions of
regulation NE 012/2:
Conformity with the design with regard to the position, shape and size of the forms, as well as
the strength, stability, non-deformability and integrity of the concrete section shall be ensured by:
a) using suitable encasing materials;
b) making sure that all supports and connections are made correctly;
c) ensuring waterproofing;
d) applying suitable stripping agents;
e) establishing the stripping methods and stages and implementing them accurately.
(2) The materials used for the manufacturing of forms are, usually, wood (timber), wooden
products, metallic products or products based on synthetic materials.
(3) Stripping agents are products applied to the surface of the forms, which come into contact
with the concrete and reduce adherence between the hardened concrete and the forms to ensure that
the concrete surface is not damaged during the stripping process.
The stripping agents shall:
a) not stain the concrete or prevent the subsequent adherence of the materials applied to the
respective concrete surface (plaster, plywood adhesives, etc.);
b) not have a negative impact on the concrete, the reinforcement and the material that the form
is made of, as well as on the environment;
c) retain their functional properties under the weather conditions in which the works are
carried out;
d) be easy to apply and enable inspection of their correct application.
(4) The installation of the forms shall consist of the following steps:
a) building scaffoldings, if applicable;
b) placing the forms in position, in accordance with the detailed drawings;
c) finalising the planar and vertical positioning, joining the panels, if applicable, and fixing the
forms in position;
d) carrying out the inspection and acceptance of the forms.
3.4.7 Reinforcements
(1) For steel elements, reference shall be made to the performance requirements and criteria
stipulated in the applicable specific technical regulations in the field of constructions in force. One
can use steel products with a smooth, ribbed or indented surface as strength or structural
reinforcements, delivered as finished products in the form of: bars, bundles (coils) or unwound products
made of hot rolled reinforcing steel and welded mesh panels manufactured in a factory using machinery; cold
rolled wire.
3.4.8 Concrete
(1) In accordance with the provisions of regulation NE 012/2, building works of a specific
nature (engineering structures - canals, reservoirs, etc.) shall also comply with the provisions of the
technical regulations in the field, as well as the provisions stipulated in the specifications drawn up by
the design engineer, as applicable.
(2) The concrete shall be prepared in concrete mixing plants, in accordance with the
applicable specific technical regulations in force.
(2) The general rules below shall be followed when pouring the concrete:
a) wooden forms, old concrete or masonry structures - which come into contact with fresh
concrete - must be soaked in water 2-3 hours before and immediately after pouring the concrete, but
the remaining water left in the recesses must be removed;
b) the concrete must be unloaded from the means of transport into buckets, pumps, belt
carriers, chutes or directly into the forms;
c) the concrete delivered to the pouring site must be refused and its utilisation must be
prohibited if it does not comply with the stipulated consistency limits or if it displays segregation; the
consistency of the concrete can only be improved by using a superplasticizer, in accordance with the
applicable provisions of NE 012-1;
d) the free fall height of the concrete must not exceed 3.0 m for elements with a maximum
