protection products prevent downtime
associated with shorter lived systems, and ourrepair products install and cure quickly, again
ensuring minimal operational disruption.

The water management sector covers thestorage and transport of untreated raw water,
the treatment of raw water to drinking water
quality, collection and transport of sewage andthe treatment of human or industrial waste prior
to discharge back the environment. These
processes create stress on the facilities built toprocess the water or waste leading to damage.
The growth in urbanization and the rapidly
growing population puts significant strain on theexisting systems. It is an expectation of urban
populations that drinking water and sanitation
are available all the time and that downtime formaintenance or breakdowns must be kept to aminimum.
In general, the preferred construction material
for the water management sector is reinforced
concrete. In sewers and in the initial phases oftreatment, the concrete can suffer severe acidattack which can lead to corrosion of thereinforcements. In downstream treatment or in
the water reticulation systems, the main causeof damage is abrasion caused by a combinationof rapid water flow and particulate matter in thewater. This can cause over time significant
erosion of the concrete and eventually exposed
the reinforcing steel leading to corrosion.
Prevention during construction through the useof low porosity concrete and the application ofprotective coatings is a growing trend however
much of the current infrastructure did not havethe benefit of this and may need remedial
treatment to extend its life.
Master Builders Solutions has extensive
experience in helping the contractors,
environmental and structural consultants andthe owners of water management structures
worldwide to design, select and install
prevention treatments. We connect our experts
across the globe to find the best remedialsystem for existing water management
structures by combining proven materials
incorporating the latest technology to provide
durable and cost effective solutions.

Treatment with an ease

Waste not wasted

During construction, any water containing
structure from a dam to a holding tank to thewater purification plant itself, it is important tominimize porosity and cracking of the reinforced
concrete. Master Builders Solutions’ Smart
Dynamic ConcreteTM utilizing theMasterGlenium® range of admixtures andMasterMatrix® additives thatare tuned to work with the local ingredients toclass leading low porosity and this is further
enhanced by the use of MasterKure® curingcompounds to ensure optimum curing of theconcrete. All reinforced concrete structures
have to have joints and the MasterSeal® range
of injectable hoses and swelling gaskets offer
long lasting and permanent sealing of
construction and expansion joints.

The increasing urbanization across the globe
especially in Asia puts strains on the existing
sewage system. Much of the sewage collection
systems in older cities dates back to the 19th
century and need to be constantly maintained
as well as extended to cope with urban sprawl.
Many cities have sections of hand build bricklined sewer tunnels which connect to thereinforced concrete tunnels built constantly
throughout the 20th and now into the 21stcentury. Many newer installations have moved
to precast pipes in an effort to build the system
faster and at lower cost.

sulphuric acid. The sulphuric acid attacks thecement matrix, weakening it and speeding theerosion of the reinforced concrete and exposing
the reinforcements to corrosion. The area above
the liquid waste has the greatest level of attack
and below the water level the main cause ofdamage is erosion.

A sewer is a very aggressive environment
created by the presence of anaerobic bacteriathat feed on the liquid waste and excretehydrogen sulphide gas (rotten egg gas) which isconsumed by aerobic bacteria living on thewalls above the liquid waste which excrete

In hazardous areas with limited access such as
pumping stations surge tanks the use ofMasterProtect highly acid resistant coatings is a
way of reducing the need for access thusincreasing the safety of maintenance personnel.

Drinking water treatment plantDams will always have spillways that aresubject to massive abrasive forces especiallyduring periods of high rainfall such as
monsoons. Repair of these with MasterEmaco®
repair materials and linings of MasterSeal®
polyurea coatings may be necessary to returnthem to correct operation.
Collection and transport pipes and channels
will suffer from erosion over the long term andwill eventually need repairing with ourMasterEmaco repair materials and may needfurther protection with a MasterProtect®
coating.
Purification of the water to a standard suitablefor drinking involves flocculation and settlingprocesses as well as sterilization andchlorination. The main process at work here is
the abrasion of the surface of the concrete by
the constant movement of the water and in thesettling and flocculation tanks the added effectof the particulates in the water abrading thesurface. After many years of service some
repairs may be necessary to ensure that thereinforcing steel is protected and theMasterEmaco range of repair mortars is ideal
for this with many having certification for use inpotable (drinking) water.
Drinking water is a vital resource in any country
and in recent years there has been a surge inthe building of desalination plants. Thechanging global climate, the changes in rainfall
patterns and the increasing urbanization havedriven this trend.
Desalination plants create a number of special
stressors for reinforced concrete, the major one
being the need to protect the concrete from thehighly salinated water returned to the sea. Thiswater with more than 10 times the salt contentof seawater creates an environment for
accelerated corrosion of the reinforcing steel. In
these areas the use of MasterProtecthydrophobic impregnations or MasterProtect
coatings is essential for the long term viability ofthe structure.

Sewage transport

The MasterEmaco range has speciallyformulated spray mortars to return structural
integrity to both brick and concrete tunnels aswell as having significant resistance to theattack of the sulphuric acid.

From waste to water
Sewage treatment

Treatment of sewage is designed to separate
the water from the waste and to clean it to thepoint it can return to the environment and toreduce the waste useful materials such as
fertilizer or to create energy through generationof biogas. The challenges in the need to control
odor and to reduce greenhouse gas emissions
created during the treatment process increase
the stress on the facilities. During constructionof a sewerage treatment plant it is important tominimize porosity and cracking of the reinforced
concrete. Master Builders Solutions’ Smart
Dynamic ConcreteTM utilizing the MasterGlenium
range of admixtures and MasterMatrix additives
that are tuned to work with the local ingredientsto class leading low porosity and this is further
enhanced by the use of MasterKure curingcompounds to ensure optimum curing of theconcrete. All reinforced concrete structures haveto have joints and the MasterSeal range of
injectable hoses and swelling gaskets offer long
lasting sealing of construction and expansion
joints.
Incoming sewerage contains much abrasive
solid matter and this must be removed througha process called grit removal. This removes
things like broken glass and other materials andabrasion resistant coatings from theMasterProtect and MasterSeal ranges can beused to protect the concrete. After removal of
the hard materials the waste is put throughaeration tanks that help to separate the waterand the solid waste. The use of MasterProtect
coatings is necessary to ensure the concrete is
not eroded by acid attack and abrasion. After
aeration the water is separated and sent toclarifiers and trickling filters to reduce thebiochemical oxygen demand (BOD) to enable it
to be discharged to the environment. Thesetanks although only handling contaminatedwater will in time suffer from some surface
erosion from bacterial growth and the use of aMasterProtect coating will significantly extend
the life. In many cases this water is returned to
the local river or sea further sterilized andsometimes is used as the input to a potablewater treatment plant.
The sludge was often just transported away to
be used as fertilizer or disposed of into landfill
but as it degrades, it releases methane andcarbon dioxide significant greenhouse gases.
This has led to a rise in the digestion of thesludge to maximize the production of methaneand to use this for the generation of electricity
or as a source of fuel for incineration of waste.

The digestion of the sludge and its
collection is now known as biogas
generation and many farm andhousehold wastes are also digested
in the same way. The biogas contains
small amounts of hydrogen sulphideand the potential for acid attack on
the concrete digester is significant
although at a slower rate and by adifferent mechanism to the process inthe sewer. The MasterProtect range
has coatings that are suitable for thisenvironment.

Retreatment

Additional Avenues

Industrial waste treatment can be broadly divided
into two categories: those that have wastes fromorganic process such as food processing orbeverage manufacture and those that havechemical wastes such as oil refineries andchemical plants. The stressors on the structuresdiffer and an individual protection or repair planshould be developed with your Master Builders
Solutions representative.

Processing or treatment plants will require
MasterFlow® precision grouts for stabilizing
machinery, Ucrete® and MasterTop® chemicallyresistant coatings for floors in battery rooms,

Industrial treatment plant

Organic wastes are in the main treated like sewage
in that the solid matter is separated and digested
and the clear liquor treated to reduce BOD. Thestress may be less but the need to clean up thewaste before discharge is just as stringent.
Chemical wastes generated are normal associatedwith quantities of water and this goes through anumber of steps such as oil and solvent removal
via either distillation or separators. The water isoften adjust to a neutral pH to allow discharge after
chemical removal and in this area coating arerequired to protect the concrete. The
MasterProtect range has coating that can copewith the sudden dosing of acids or alkalis for pHadjustment.
