RAINWATER HARVESTING & WATER CONSERVATION SYSTEMS - COURSE OUTLINE

Course Overview

The Rainwater Harvesting & Water Conservation Systems Course at the Zebra Liquid Vocational Institute is a 1-month intensive vocational program. This course provides practical skills in designing, constructing, and maintaining low-cost domestic and agricultural rainwater harvesting infrastructure. Topics include roof catchment sizing, gutter installation, first-flush diverter fabrication, ferro-cement storage tank construction, and drip irrigation integration. Water scarcity poses significant challenges across East Africa; this course trains technicians to deliver essential water security solutions.

Combining plumbing techniques, masonry, filtration biology, and business management, this course equips participants to start water service businesses or work with development agencies. Graduates receive post-training mentorship and market linkages.

Course Objectives

By the end of the course, participants will:

1. Calculate rainwater yield potentials based on roof surface area, catchment material, and rainfall data.

2. Install guttering, downspouts, leaf screens, and self-cleaning first-flush diverter systems.

3. Construct durable, low-cost ferro-cement water storage tanks and underground cisterns.

4. Assemble bio-sand water filters and basic solar/chlorination disinfection systems for safe drinking water.

5. Establish a water conservation installation business, price contracts, and market services to communities.

Course Structure and Topics

Week 1: Fundamentals of Rainwater Harvesting and Catchment Design

• Hydrology & Catchment Basics: Rainfall patterns, runoff coefficients, and roof material suitability.

• Sizing Storage Tanks: Calculating household water demand vs. available roof runoff volume.

• Guttering Systems: Bracketing, slope alignment, PVC/sheet metal gutter selection, and leaf guards.

• First-Flush Diverters: Sizing and constructing mechanical diverters to flush initial dirty roof washings.

• Hands-On Practice: Measuring a roof catchment, calculating water yield, and constructing a PVC first-flush pipe diverter.

Week 2: Construction of Storage Tanks (Ferro-Cement & Masonry)

• Storage Options: Plastic tanks, brick masonry cisterns, and ferro-cement tank technology.

• Ferro-Cement Construction: Assembling wire mesh frame skeletons, reinforcement, and plastering mix ratios.

• Tank Foundation & Outlets: Casting reinforced concrete base slabs, fitting brass valves, overflows, and drain pipes.

• Curing & Waterproofing: Curing cement renders, applying non-toxic food-grade sealant coats.

• Hands-On Practice: Building a 2,000-liter ferro-cement rainwater storage tank from mesh framing to final plastering.

Week 3: Water Filtration, Purification, and Conservation Systems

• Water Quality & Testing: Identifying physical, biological, and chemical water contaminants.

• Bio-Sand Filters: Constructing household sand-gravel bio-filters for pathogen removal.

• Disinfection Methods: Solar Water Disinfection (SODIS), UV treatment, and safe chlorination dosing.

• Agricultural Integration: Linking tank storage to gravity-fed drip irrigation kits for gardens.

• Hands-On Practice: Assembling a bio-sand filter unit and connecting a rainwater tank to a garden drip-irrigation kit.

Week 4: Business Management, Contracting, and Service Delivery

• Costing & Quoting: Estimating bill of quantities (BOQ) for materials, labor, and profit margins.

• Marketing Water Solutions: Targeting rural/peri-urban households, schools, farms, and institutions.

• Maintenance Contracts: Offering annual cleaning, gutter clearing, and filter replacement services.

• Business Plan Development: Registering a plumbing/water enterprise and forming installation teams.

• Hands-On Practice: Preparing a technical cost quotation for a school rainwater system and presenting a pitch.

Training Approach

• Trainer-Learner Ratio: 1 trainer per 30 learners to ensure personalized instruction.
