About Howota
Since 2008, Howota has been manufacturing water filtration systems in London, supplying residential and commercial clients across the United Kingdom. Our facility on Elmfield Road produces reverse osmosis units, carbon filter cartridges, and sediment filters using materials sourced from certified European suppliers.
Our Foundation
The company started when three chemical engineers identified a gap in the UK market for locally manufactured filtration systems. Instead of importing pre-assembled units, we established a production line that allows us to control every stage – from selecting activated carbon grades to testing membrane performance.
Our first product line consisted of under-sink filters for domestic use. Within two years, we expanded to commercial-grade systems for restaurants and offices in Greater London. By 2012, we were shipping to Birmingham, Manchester, and Edinburgh.
What We Do
Each filter undergoes pressure testing at 6 bar and flow rate verification before leaving our workshop. We use NSF-certified components and maintain documentation for every batch. Our reverse osmosis membranes remove 96-98% of dissolved solids, measured with calibrated TDS meters.
For commercial clients, we design multi-stage systems based on water analysis reports. A café in Brixton required chlorine removal and scale prevention – we installed a three-chamber unit with KDF media and polyphosphate crystals. The system processes 150 litres per hour.
We also manufacture replacement cartridges compatible with major brands. Our carbon blocks use coconut shell material with 5-micron rating, suitable for reducing taste and odour compounds.
Our production facility holds ISO 9001 certification for quality management. We conduct quarterly audits and maintain traceability records for all materials used in manufacturing.
Expertise and Capabilities
Our team includes specialists in membrane technology, water chemistry, and hydraulic engineering. We work with Thames Water reports to understand regional contaminant profiles – hardness levels in South London differ from those in North London, requiring adjusted filter specifications.
We've developed custom solutions for schools, dental practices, and food production facilities. Each application requires different filtration stages. A bakery in Croydon needed sediment removal and bacterial reduction – we configured a system with pleated filters and UV sterilization.
Technical support is available during business hours. Our engineers can interpret water test results and recommend appropriate filtration methods. We stock spare parts for systems we've installed over the past decade.
Core Principles
Manufacturing Standards
We follow British Standards Institution guidelines for water treatment equipment. All components meet WRAS approval requirements for contact with drinking water.
Testing Protocols
Every unit undergoes leak testing, flow rate measurement, and contaminant reduction verification. We maintain calibration certificates for all testing equipment.
Material Selection
We source food-grade plastics, lead-free brass fittings, and certified filter media. Supplier documentation is reviewed annually to ensure compliance.
Client Communication
We provide installation manuals, maintenance schedules, and performance data sheets. Technical questions are answered by qualified staff, not automated systems.
