Retas Water Solutions (also known as Retas / Retas Enviro Solutions) is a specialist provider of modular rainwater harvesting systems, underground and above-ground storage tanks, stormwater management and industrial water conservation solutions. The founders—three MBA graduates who left corporate careers to become ‘waterpreneurs’—launched the company to design, manufacture and install scalable rainwater solutions for urban, industrial and institutional customers.
History & Evolution
Founded in the late 2010s, Retas began as a focused rainwater-harvesting venture that developed compact, modular tanks and systems intended to maximize rainwater capture and reduce dependence on municipal supplies. Early product development emphasized space-efficient designs using recyclable materials and modular construction so systems could be deployed across low-rise and high-rise contexts, commercial campuses, manufacturing sites and public infrastructure projects.
Expertise & Capabilities
Retas combines product design, fabrication, systems engineering and end-to-end project delivery. Core capabilities include site assessment and hydrologic analysis, custom tank and module design, stormwater and flood-risk solutions, on-site water treatment for reuse, and O&M programs to ensure long-term performance. Their teams are experienced in adapting systems for rooftop, surface, and subsurface installations and integrating rainwater harvesting into larger sustainable-water and green-infrastructure strategies.
Approach & Philosophy
Retas follows a practical, data-driven approach: assess rainfall inputs and catchment areas; model demand and storage requirements; recommend modular tanks and pre-treatment; and deliver installation plus scheduled maintenance. The company emphasizes long-term resilience—reducing flood loads during peak events and building non-potable water capacity for irrigation, HVAC make-up, process water and sanitation—while prioritizing low life-cycle cost and easy scalability.

Pros and Cons
Pros
- Specialized expertise: Deep technical knowledge in rainwater-harvesting and subsurface storage systems yields better-designed solutions than generic vendors.
- Modular, space-saving products: Ideal for urban and high-rise contexts where traditional tanks are impractical.
- End-to-end project capability: Design, manufacture, installation and O&M reduce coordination burden for customers.
- Proven industrial clients: Experience with large corporate and government clients demonstrates scalability and compliance experience.
- Sustainability benefits: Systems lower municipal water dependence, support groundwater recharge and help manage stormwater risks.
Cons / Considerations
- Location & Service Area Variability: Retas’ physical presence and lead times may vary by region; some clients outside primary service areas may see longer delivery or higher logistics costs.
- Upfront capital cost: While payback from reduced water bills and avoided stormwater charges can be compelling, initial investment in tanks, filtration and installation may be higher than simple cistern alternatives.
- Site constraints and retrofits: Complex retrofits in dense urban structures can require additional civil work or structural assessment, increasing project scope and schedule.
- Maintenance requirement: Like all water-capture systems, performance depends on periodic maintenance (filtering, desludging and checks); customers must budget for O&M or purchase a service contract.
Tips for Clients
- Start with a site assessment: Ask for a hydrologic and demand audit to size storage correctly—oversizing wastes capital, undersizing limits benefits.
- Plan for O&M: Include a maintenance contract or schedule to preserve water quality and performance.
- Consider multi-benefit designs: Combine rainwater harvesting with landscaping, groundwater recharge and stormwater detention to maximize value.
- Check local incentives: Some municipalities or utilities offer grants, rebates or expedited permitting for rainwater harvesting—factor these into the financial case.
- Document for compliance: Request as-built drawings, sampling reports and warranty details to simplify future audits and reporting.
