Let's discuss your water treatment needs — from design through commissioning.
Everything you need to understand how water is treated, how facilities are managed, what products are used, and what quality standards mean — explained clearly by our engineers.
Modern water treatment is a multi-stage process that systematically removes physical, chemical, and biological contaminants. Here is how each stage works and why it matters.
Raw water often contains fine suspended particles — clay, silt, organic matter — that are too small to settle on their own. Coagulation involves adding a chemical coagulant (typically aluminium sulphate or ferric chloride) that neutralises the electrical charges on these particles, causing them to clump together. The gentle mixing process that follows, called flocculation, encourages these clumps to grow into larger, heavier particles called "floc".
The choice of coagulant dose and pH is critical and varies by source water quality. Overdosing wastes chemical and can leave residual aluminium in treated water. Under-dosing leaves turbidity and colour unresolved.
After flocculation, water flows slowly through large sedimentation tanks (also called clarifiers). Gravity causes the heavy floc particles to sink to the bottom as sludge, while clearer water rises to the surface and overflows into the next treatment stage. This process removes the bulk of suspended solids — typically 60–80% of turbidity — before filtration begins.
Some modern plants use dissolved air flotation (DAF) instead — injecting microscopic air bubbles that carry floc particles to the surface, where they are skimmed off. DAF is particularly effective for algae-laden water.
Settled water passes through filter beds — layers of sand, gravel, and often anthracite or activated carbon — that trap remaining particles too fine to settle out. Rapid sand filters are the most common type in municipal treatment, capable of processing high flow rates. Slow sand filters also support biological filtration through a layer of microorganisms called the schmutzdecke that biologically degrades organics.
Membrane filtration (microfiltration, ultrafiltration) is increasingly used as a more absolute barrier — removing particles, protozoa like Cryptosporidium and Giardia, and even some viruses based on pore size alone.
Even after filtration, bacteria, viruses, and other pathogens may remain. Disinfection is the final kill step. Chlorination is the most widespread method globally — adding chlorine or chloramine that destroys microorganism cell walls. Chlorine also provides a disinfection residual throughout the distribution network.
UV disinfection uses ultraviolet light to damage pathogen DNA, preventing reproduction — without adding chemicals. Ozonation provides powerful disinfection and also oxidises taste and odour compounds. Many plants use a combination: UV or ozone as primary disinfection, with a low chlorine residual for distribution protection.
Treated water is adjusted to the correct pH (typically 7.0–8.5) before distribution. Corrosive water (low pH) will attack metal pipes and fittings, leaching lead and copper into drinking water. Alkaline water can form scale. Lime or caustic soda is typically added to raise pH; carbon dioxide or acid is used to lower it. Corrosion inhibitors such as orthophosphate may also be dosed.
For applications requiring ultra-pure water — pharmaceutical, electronics, boiler feed, or highly contaminated source water — reverse osmosis is employed. Water is forced under pressure through semi-permeable membranes with pores of approximately 0.0001 microns, rejecting dissolved salts, heavy metals, nitrates, fluoride, and most micro-pollutants. RO is also the core technology in seawater desalination plants.
RO requires thorough pre-treatment to prevent membrane fouling and scaling. A recovery rate of 70–85% is typical — meaning some water is lost as concentrate (reject). Energy consumption is higher than conventional treatment, though energy recovery devices have significantly reduced this in large installations.
Facility management is the discipline of keeping the physical systems and spaces that support a building or estate running reliably — from generators and fire systems to cleaning schedules and landscaping. Here is how the discipline works and what to expect from a properly managed contract.
Facility management is the coordinated operation and maintenance of the systems, spaces, and services that keep a building or estate functioning — electrical and mechanical plant, fire safety, cleaning, landscaping, waste, and security. It is distinct from construction: facility management begins after a building or estate is handed over, and continues for as long as it is occupied.
Facility services split into two broad categories: hard services, which are the physical, technical systems a site depends on — generators, HVAC, electrical distribution, fire systems, mechanical plant; and soft services, which cover day-to-day upkeep and occupant experience — cleaning, landscaping, waste management, and security supervision. Both categories need to operate in coordination, not as separate, uncoordinated contracts.
Total Facility Management consolidates every hard and soft service under a single contract, a single on-site management team, and a single performance framework. Instead of a client managing separate contractors for generators, cleaning, security, and landscaping — each with its own standards, invoicing, and no shared accountability — a TFM provider takes ownership of outcomes across the entire site.
This matters most for institutions, estates, and large commercial facilities where service failures compound: a generator fault during a cleaning shift, or a fire system inspection missed because three different contractors assumed someone else was responsible. One accountable interface removes that risk.
Reactive maintenance — fixing equipment only after it fails — is the most expensive way to run a facility. Preventive maintenance follows a planned schedule of inspection, servicing, and part replacement based on manufacturer intervals and actual usage data, catching faults before they cause downtime or costly emergency repairs.
For mechanical and electrical assets specifically, this includes generator servicing and fuel management, electrical panel inspection and thermographic surveys, HVAC servicing cycles, and pump and motor performance monitoring. A documented maintenance history also protects asset value and simplifies insurance and compliance audits.
Facility contracts only work when performance is measurable. Service Level Agreements (SLAs) define what "acceptable" looks like for every service line — response times for a fault call, cleaning frequency for a lobby, uptime targets for a generator. Key Performance Indicators (KPIs) track actual performance against those definitions over time, not just at contract signing.
A properly run facility management contract includes monthly performance reporting and quarterly reviews, giving clients visibility into what is working, what is not, and what needs to change — rather than relying on complaints as the only feedback mechanism.
Gated estates, residential communities, and mixed-use developments have facility needs distinct from a single commercial building — common area maintenance, service charge coordination, resident enquiries, and community-level access control and security supervision, alongside the same hard-service needs as any other property.
Because residents are also the client, estate FM carries an additional layer of communication and rule enforcement that commercial facility management does not — service charge transparency and responsive resident support are often what determine whether a management contract is renewed.
Water treatment systems are themselves facility assets — pumps, dosing systems, filtration skids, and RO membranes all require the same preventive maintenance discipline as generators or HVAC. Managing them separately from the rest of a site's facility operations creates the same accountability gap that Total Facility Management is designed to close.
That is why we deliver both under one team: the engineers who design and install a water treatment system are the same organisation responsible for its ongoing operation, alongside the rest of a client's mechanical, electrical, and soft-service needs — one contract, one point of contact, one standard.
Avalanche Engineering supplies, installs, and maintains a complete range of water treatment equipment — from standalone residential units to large industrial systems. Here is what each product does and how to choose the right one.

Full-scope management of residential estates and mixed-use developments — covering common area maintenance, resident services, access control, and contractor coordination under a single accountable team.
Water quality is defined by physical, chemical, and microbiological parameters. Understanding these parameters helps you know what your water treatment system must achieve and how to verify it.
Physical parameters describe the appearance and feel of water. Turbidity (cloudiness) is one of the most important — it indicates suspended particles and can shield microorganisms from disinfection. Colour, temperature, and taste/odour are also assessed. These are often the first signs of a problem.
Chemical parameters include pH, hardness, dissolved oxygen, total dissolved solids (TDS), nitrates, fluoride, heavy metals (lead, arsenic, mercury), and organic compounds. Each has a guideline value set by WHO or national regulators. Exceeding these can have serious health implications.
Microbiological safety is the most critical aspect of drinking water quality. Indicator organisms — E. coli, total coliforms, and Enterococci — are routinely tested. Their presence indicates faecal contamination and the potential presence of pathogenic bacteria, viruses, and protozoa such as Cryptosporidium and Giardia.
In Nigeria, water quality standards are set by the National Environmental Standards and Regulations Enforcement Agency (NESREA) and the Standard Organisation of Nigeria (SON). These align closely with WHO Guidelines for Drinking-water Quality. Our systems are designed to meet or exceed these standards.
| Parameter | WHO Guideline | SON Limit | Unit | Status |
|---|---|---|---|---|
| Turbidity | < 1 | < 5 | NTU | Safe |
| pH | 6.5 – 8.5 | 6.5 – 8.5 | — | Safe |
| Total Dissolved Solids | < 600 | < 500 | mg/L | Safe |
| Nitrates (NO₃) | < 50 | < 50 | mg/L | Monitor |
| Fluoride | 1.5 | 1.5 | mg/L | Monitor |
| Arsenic | 0.01 | 0.01 | mg/L | Monitor |
| Lead | 0.01 | 0.01 | mg/L | Monitor |
| E. coli | 0 | 0 | CFU/100mL | Safe |
| Total Coliforms | 0 | 0 | CFU/100mL | Safe |
| Residual Chlorine | 0.2 – 0.5 | 0.2 – 0.5 | mg/L | Safe |

Avalanche Engineering Services Limited is a Nigerian water treatment, mechanical and electrical, and facility management company operating from Victoria Island, Lagos. The business was established in 2001 as Avalanche Koncept, delivering engineered water treatment solutions to homes, hotels, schools, offices, and industrial facilities across Nigeria — a market in which reliably potable water, as defined by World Health Organization guidelines, remains difficult to source.
Over the following two decades, the scope of the business expanded from water treatment into a broader engineering and facility management offer, driven by client demand for a single, accountable provider capable of designing, installing, and operating integrated systems.
In 2023, the business was formally incorporated as Avalanche Engineering Services Limited, taking over the operations of Avalanche Koncept without dilution of ownership. The company now enters its 25th year of continuous operation, with clients spanning residential estates, educational institutions, food and beverage manufacturers, hotels, and commercial properties.
From our base in Victoria Island, we design, supply, install, commission, maintain, and operate water treatment and facility systems across the full spectrum of scale and application. Our current portfolio includes municipal-scale treatment plants, industrial process and effluent systems, institutional water and facility management contracts, and residential filtration installations.
We believe engineering — whether in water systems or facility operations — should be transparent, practical, and built around the specific characteristics of the site being served. There is no single solution. A borehole in Lagos has different challenges from river water in the Niger Delta or industrial effluent from a food processing plant. An estate in Ikeja has different operational demands from a boarding school in Abeokuta or a food manufacturer in Ibadan.
Every water engagement begins with thorough source water analysis. Every facility engagement begins with a documented site assessment and risk register. We test and measure before we design — because a system engineered around actual data will always outperform one built on assumptions.
Our designs are modular and scalable, allowing systems to be expanded as demand grows without complete redesign. Our facility contracts are structured around documented Service Level Agreements (SLAs), measurable Key Performance Indicators (KPIs), and monthly performance reporting — because facility management works when it is measurable and accountable.
We are also committed to technology transfer and operational continuity. For every project we deliver, we train the operators who will run the system long after our engineers have left the site. Clean water and reliable facilities require not just the right equipment, but the right people running them.
To deliver water treatment and facility management solutions engineered to international standards, with the operational discipline and response times that reflect the stakes of our clients' work.
To provide considered engineering and dependable facility services, delivered with the discipline, accountability, and long-term partnership our clients rely on.
Our team combines engineers with hands-on field operators. We recruit for technical judgement as much as for qualification, and we invest continuously in training so that our people can respond to the specific characteristics of each site and each system they manage. The management team brings sector experience spanning water treatment, mechanical and electrical systems, industrial process engineering, and integrated facility operations. The organisational structure is aligned to the operational and service needs of each client segment we serve, ensuring accountability at every level of delivery. Long-term client retention and growth by referral remain our two most reliable indicators of performance, and we manage the business against both.
