rainwatermanagement.com

At a Glance
The company reports over 70 years of experience in rainwater harvesting. Their proprietary tank sizing software guides system design for residential, commercial, and agricultural installations. The site pairs that design tool with wholesale equipment and consulting services at the project level.
Core Features
Rainwater Management combines a design tool with a broad product catalog that covers filters, tanks, pumps and filtration components. The offering includes consulting and system design services plus educational resources and workshops aimed at installers and project managers. The combination helps translate modeled tank sizes into real-world installations.
Key Differentiator
The main distinction is the tank sizing tool integrated into a full-service offering. That software ties engineering inputs to equipment choices and consulting recommendations, reducing guesswork for large projects. The linkage between design output and product availability sets it apart from vendors that sell hardware only.
Pros
Rainwater Management brings deep experience and a product-plus-service approach that suits multi-site and municipal projects. Their catalog and design workflow let engineers move from model to procurement without recreating system calculations. The educational resources and workshops help clients learn the rationale behind sizing decisions and operation practices.
Cons
-
Limited public pricing: the company does not publish standard price sheets or package rates, so you will need to request quotes.
-
Complex selection for beginners: first-time homeowners or small-scale users may find the product mix and design choices heavy without consulting support.
-
Availability may vary: some items could require special orders or longer lead times for large tanks or custom components.
Who It’s For
Professionals and organizations managing large-scale rainwater systems will get the most value. Ideal audiences include engineers, consultants, contractors, and government agencies responsible for municipal or commercial installations. Homeowners seeking turnkey off-grid kits may find the offering more technical than they need.

Rainwater Harvesting for Drylands and Beyond by Brad Lancaster

At a Glance
The site concentrates on practical water and landscape work for drylands such as Tucson, Arizona. According to the organization, Brad Lancaster is the author of award winning books on drylands water harvesting and ecological design. Visit harvestingrainwater.com to access the core resources and project examples.
Core Features
The site bundles educational guides, books, and stepwise project notes that teach passive and active harvesting methods for yards and neighborhoods. The collection includes detailed online resource library items such as calendars, plant lists, site assessments, and recorded tours that support design and implementation. Case studies and workshop materials connect the theory to real neighborhood projects.
Key Differentiator

Pros
The resource set delivers highly practical guidance that helps homeowners convert runoff into usable landscape water while improving soil and plant health. It emphasizes low cost, locally driven tactics and shows stepwise project sequences through photographs and plans. The site supports community resilience with workshop material and case studies that show neighborhood scale outcomes.
Cons
- Primarily focused on dryland environments such as Tucson, Arizona. This focus means design details may need adjustment for wetter or colder climates.
- Some content reads at a technical or academic level. Complete beginners may prefer more basic, entry level primers.
- The offering is education and guidance only. There is no hardware sales or direct installation service for hands on assistance.
Who It’s For

Panama Rainwater

At a Glance
Panama Rainwater has worked on community water projects in Panama since 2015. The group focuses on rain capture, well drilling, storage, and distribution in rural areas. Their projects often pair water systems with solar-powered pumping and filtration, and local social impact is a clear priority. Visit Panama Rainwater for project examples and contact details.
Core Features
Panama Rainwater installs rainwater harvesting systems and drills wells, and it builds aqueducts and storage tanks to move and hold water for communities. The team integrates solar-powered pumping and filtration into systems that range from school installations to agricultural infrastructure. Project work combines construction, mechanical systems, and local training to hand over functional water systems.
Key Differentiator
The firm pairs engineering projects with social-program goals to improve rural living conditions. That combination of technical delivery and community focus distinguishes their approach from purely commercial contractors. The result tends to be systems designed for local maintenance and long term use.
Pros
Panama Rainwater offers deep local experience in Panamanian water projects and a track record working in rural communities. The team delivers end-to-end work from capture and storage to pumping and distribution, which reduces the number of contractors you must coordinate.

The group also emphasizes social outcomes and local capacity building, which helps projects stay operational after handover.
Cons
- Service area is limited to Panama and nearby regions. Projects outside that area are not supported.
- Project costs vary with site conditions and scale, so budgets can change during planning.
- The vendor does not publish standard prices or financing options publicly.
When It May Not Fit
This provider is the wrong choice if your project sits outside Panama or its neighboring regions. Large commercial or industrial clients seeking national rollout support might find the scope too localized. If you need fixed, published pricing or packaged financing, the lack of public pricing could slow procurement.
Who It’s For
Organizations, public institutions, and private groups in Panama that need integrated water systems will find this a close fit. Community development programs and NGOs seeking social outcomes from infrastructure projects will value the local focus. Municipalities with scattered rural settlements are also a natural match.
Real World Use Case
A rural school installs a rainwater catchment system and a storage tank to supply classrooms and a kitchen. Panama Rainwater pairs the tank with a solar-powered pump and a basic filtration unit to provide safe water year round. Local staff receive operation training and a maintenance handover at project completion.
Pricing
Not applicable — informational only. Panama Rainwater does not list fixed prices on its site, and project fees are estimated per site after assessment. Contact the team through their website to request a scoped quote and a site visit.
