Plumbing and public health engineering form the backbone of safe, hygienic, and code-compliant buildings. Every residential, commercial, institutional, and industrial development depends on properly designed water supply, drainage, and wastewater management systems to ensure health, safety, durability, and operational efficiency.
At Cadreatech Engineering Services Ltd, we provide comprehensive plumbing and public health engineering design services in Kenya and across East Africa. Our team delivers technically sound, efficient, and regulatory-compliant systems tailored to residential estates, apartments, commercial buildings, hospitals, schools, industrial facilities, hotels, and infrastructure projects.
We integrate water supply systems, sewer reticulation, stormwater drainage, hot water systems, and specialized plumbing installations with architectural, structural, and MEP designs to produce coordinated, buildable, and cost-effective engineering solutions.
Water Supply System Design
A reliable water supply system is critical to building functionality and occupant comfort. We design efficient and sustainable domestic and commercial water distribution systems that ensure adequate pressure, balanced flow rates, and long-term reliability.
Our water supply engineering services include:
-
Cold water distribution system design
-
Hot water reticulation systems
-
Pipe sizing and hydraulic calculations
-
Water demand and diversity calculations
-
Booster pump selection and specification
-
Pressure zoning for multi-storey developments
-
Underground and elevated water storage tank sizing
-
Rainwater harvesting system integration
-
Backflow prevention systems
We carefully analyze static and dynamic pressures, fixture units, pipe materials, and peak demand scenarios to ensure optimal performance. All designs comply with Kenyan building regulations, public health standards, and applicable international plumbing codes where required.
By delivering efficient water reticulation systems, we help clients minimize pressure losses, prevent pipe failures, and reduce long-term maintenance costs.
Drainage and Sewer System Design
Proper wastewater management is essential for public health, environmental protection, and regulatory compliance. Our drainage and sewer system designs ensure safe removal of foul water while preventing blockages, backflow, and structural damage.
Our drainage engineering services include:
-
Soil and waste pipe system design
-
Underground sewer reticulation
-
Manhole design and detailing
-
Invert level calculations
-
Septic tank and soak pit design
-
Biodigester system design
-
Grease trap design for commercial kitchens
-
Connection to municipal sewer networks
-
Wastewater treatment integration
We ensure proper gradient calculations, vent stack sizing, trap design, and inspection chamber placement to guarantee effective wastewater flow and ease of maintenance.
All drainage systems are designed in compliance with the Public Health Act (Kenya), county government regulations, and environmental standards.
Stormwater Drainage Systems
Uncontrolled stormwater can lead to flooding, structural damage, and environmental hazards. As a multidisciplinary engineering firm, Cadreatech integrates plumbing and stormwater drainage solutions to protect developments from water-related risks.
Our stormwater design services include:
-
Roof drainage system design

Public Health Engineering Compliance
All our plumbing and public health engineering designs comply with:
-
Kenyan Building Code
-
Public Health Act (Kenya)
-
County Government approvals
-
WASREB guidelines (where applicable)
-
Environmental and sanitation standards
-
Relevant mechanical and plumbing codes
Our team prepares complete submission drawings and documentation required for approvals and regulatory compliance.
Our Engineering Design Process
At Cadreatech Engineering Services Ltd, we follow a structured and professional approach to plumbing and public health design:
1. Project Assessment and Water Demand Analysis
We evaluate occupancy levels, building use classification, and fixture units to determine accurate demand calculations.
2. Hydraulic Calculations and System Sizing
We conduct detailed pipe sizing, pressure analysis, and pump head calculations to optimize performance.
3. System Layout and Multidisciplinary Coordination
We coordinate plumbing layouts with structural beams, slabs, foundations, and architectural features to prevent clashes and redesign during construction.
4. Detailed Engineering Drawings and Schedules
We produce clear and buildable drawings, including layouts, schematics, manhole schedules, pipe specifications, and equipment schedules.
5. Site Supervision and Inspections
Where required, we provide technical oversight during installation to ensure compliance with approved designs.
6. As-Built Documentation
We prepare as-built plumbing drawings reflecting final installation for record purposes and future maintenance.
