Ettiene van der Merwe and his team recently installed 2 x 5000 litre JoJo tanks and pump for us. We are very pleased with the result and are now using the harvested rain water. The team worked efficiently and completed the job within the time specified.

Ettiene came in to advise us on installing a water storage system using rain water from our roof. His advice, recommendations and knowledge of water saving methods were exceptional. His service was very professional and his enthusiasm for what he does was very evident. I would not hesitate to recommend him.
Lee D - Atholl, Johannesburg
Ettiene and his team did the installation to my full satisfaction. I found Ettiene very understanding when I made suggestions and requests that were not on the table. (Unlike other installers.) I can honestly recommend him and his team highly.
Great job.

Dear Ettiene

I would like to sincerely thank Gratech for the most professional installation of 3 x 5, 000l water tanks, a pump, garden taps and a water filter system on our property in September 2014. Your work is of the highest standard. You were always available to answer our many questions both during and after the installation and you offered excellent advice. Our water harvesting system is working brilliantly and we can't thank Gratech enough for making our first step towards sustainable living, an absolute pleasure. You delivered on your promise when you said that Gratech will install a system that will take us off municipal water - for as long as the rains are good enough to keep the tanks full. We also love the home filtration system and we think that the water is definitely of a superior quality to municipal water. Thank you also for the grey water system that you so kindly donated to us to get us going with recycling water. That too, works brilliantly. And the cherry on the top is that the entire system is made in South Africa.

Attached are our recent water bills before and after using harvested water. These bills are up to before the first heavy rains in the first week of December 2014. The tanks are now filled to capacity. Your advice as to where to place the tanks was spot on, and even the light rains have yielded enough water. Our most recent water bill is ZERO.

We are extremely satisfied with our Gratech water harvesting system and I can't recommend Gratech highly enough.

Yours sincerely,
Sally N - Linden, Randburg

Dear Ettiene,
As mentioned verbally, we are very pleased that we decided to ask you to install the 2 x 3000L RainCell and 2 x 750L SlimLine tanks at our home. It was evident from the first meeting when you looked at the available space and "problem areas" on our property and proposed the best way forward, that you have a wealth of expertise and experience in this field.
We were further extremely impressed by your professionalism, conscientiousness and commitment and appreciated the fact that you explained and discussed all your proposals with us to ensure that we would be happy with the end result.
It is rare nowadays to find companies who:
  • Send quotes on the promised date and/or reply to mails/calls within hours;
  • Confirm delivery and installation dates in advance - and then meet these dates (and even confirming on the day before that the date would still be suitable);
  • Have experienced, efficient and friendly staff to ensure that all work is carried out properly - and notwithstanding the efficiency of the staff, do not merely drop them and tools/equipment at the property and then leave them to work without any supervision and instructions/guidance. (I will forward photos demonstrating how hard you personally worked as well, bearing in mind that we were experiencing a heatwave at the time);
  • Would be prepared to assist with the removal of a hedge/branches from the premises even if this was not discussed during the first meeting;
  • Work neatly and smartly, leaving the area where the work was carried out, in an immaculate condition.
When we decided halfway through the installation of the 3 tanks we originally ordered to add a second 750L SlimLine tank, you not only immediately ordered the tank, pump and pump cover, but went out of your way to arrange to find time in your extremely busy schedule to install the tank before the predicted heavy rainfall. (as advised via SMS, this ensured that we were able to harvest 750L when Beverley/Lonehill area received the predicted 84mm two days after the said installation!!).
It truly was a pleasure meeting you and witnessing how professional your work is, and we would not hesitate to recommend GratechWater to anyone interested in harvesting rainwater. May GratechWater continue to grow from strength to strength and prosper!
Kindest regards
Beaulah and Marius S - Beverley Ext, Fourways
Hallo Ettiene,
Trust I find you well! I just want to take this opportunity to thank you and Wesley for a job well done. Your work speaks of professionalism, a high standard of craftsmanship and quality. Feel free to mention me at any time as a reference; it will only be my pleasure.
Once again, I thank you.
Boet M - Constantia Gardens, Roodeport
As part of our home renovation in Parkview, we asked Ettiene and his team at Gratech to install a rainwater harvesting and filtration solution for us. We are extremely satisfied with the result. His passion in his field was clearly evident and he has gone about assembling the components that deliver a high quality product. He delivered on time without any fuss, and his team of installers showed a high level of professionalism. We would, without hesitation, recommend this solution for anyone considering rainwater harvesting.
Mike and Heidi G - Parkview
Ettiene van der Merwe and GratechWater provided absolutely first-class service, following our request to install three JoJo tanks on our property.
Ettiene was most helpful throughout the entire process, ensuring that our requirements were met in every regard.
The actual installation of the tanks and pump was done speedily and efficiently, and each worker seemed to have considerable experience at his specific job. Much of the work was done by Ettiene himself, which gave me confidence that everything was done exactly right.
The system has performed flawlessly since installation. I couldn't be happier.
Chris P - Greenside, Johannesburg
Concerned about the ongoing reliability of the water supply in our area of Johannesburg, I wanted to find a professional, effective and cost-effective solution to my concerns. I was put in touch with Ettiene at GratechWater - whom I had not heard of before.
From the first introduction, to the completion of the project, the interaction was excellent, and I greatly enjoyed the experience of working with a truly professional firm and an engaging and client-centric person, Ettiene.
He listened to our requirement, and with very little fuss proposed a solution, provided a quote (which I accepted), and then proceeded with the installation.
We now have an aesthetically pleasing tank and pump configuration, at the rear of our home, drawing water from either the municipal supply or from our borehole, storing that water, and pumping it directly into our home whenever the mains supply is interrupted.
It is indeed a pleasure to end up with a finished product which is what was wanted and that works very well, and to have enjoyed the whole experience of engaging with the supplier/installer.
I would unreservedly recommend Ettiene, and GratechWater, to whomever has the same or a similar need.
David L - Dunkeld, Johannesburg
After experiencing a number of water outages at home, we decided to look into a back-up solution. Gratech Water came highly recommended and we were not disappointed. The quotation was competitive and the installation, testing and sign off was done professionally with regular updates as to status. Post sign off, Ettiene was always available to answer questions and I have no hesitation in recommending Gratech Water to anyone looking for a water back-up solution.
Ashley M - Morningside, Sandton
Ettiene particularly impressed me with the calibre of his advice, which was the primary reason I chose Gratech instead of a competitor. He thinks long term and insists on installing solutions which can be used as a base for further work over time. The installation itself went smoothly and I will definitely do future work with Gratech as I reduce my reliance on municipal water to nothing.
Ghita E - Emmarentia, Johannesburg
Ettiene and his team installed a large 10,000 JoJo tank in our garden for rainharvesting - the tank was negotiated over my neighbour's wall with great care because our access was very limited. Our rainharvesting system was integrated into an existing irrigation system which needed some adaptations. Ettiene saw to these changes straight away and the system is working perfectly. Ettiene also changed our tank level indicator as he was unhappy with the first one. We found the team to be very conscientious and neat on site and would recommend them highly.
Gill P - Saxonwold, Johannesburg
Had GratechWater's Ettienne Van Der Merwe quote me for a back-up water system. He immediately went to my house made solid recommendations and gave me a final quote. He met all the conditions I requested and was extremely efficient in installing the whole system including delivery , plumbing and electrical work. His actual installation was done before the required time and the workmanship was great. I have no hesitation in recommending his company.
Adrian S - Blairgowrie, Randburg
Many thanks for the installation of the JoJo Water tank which you installed at my residence. Everything was done professionally and in the time promised and I can honestly say that it was an absolute pleasure doing business with Gratech - it is indeed very seldom that I have been so impressed with the service and quality of workmanship. I would also like to advise you that I was equally impressed with your plumber Wesley - he arrived on time and cleared up everything after installation. I can and will highly recommend your Company.
Joan W - Hyde Park, Johannesburg
Ettiene and the team were absolutely great with their assistance. They did a rain water harvesting installation for me at my home. His team were friendly and efficient and accommodated my request to minimise disruption to my flower beds (especially my clivias). It was a highly professional job and they cleaned up after they were done. Ettiene made every effort to keep me up to date on progress and walked me through every step of the system after installation. I am more than satisfied with the work and would happily recommend their services.
Linda F - Parkhurst, Johannesburg
We were fortunate enough to have Gratech install a water backup system at our house. You can count yourself lucky if Ettiene and his team are willing to take you on as a client! They take service excellence to the next level! The process was absolutely seamless, their workmanship is of the highest quality, they keep you informed every step of the way and the end product is the "Rolls Royce" of water backup systems! You can see they have done this a million times and have the experience to show that, and yet give each project their full attention. Since the installation our suburb has struggled with water shortages, but we have been completely oblivious due to our new setup. A big Thank you to Ettiene and team!
Marli D - Riverclub, Johannesburg
Gratech installed a 10 000 litre rainwater harvesting and filtration system at our home in November 2015. We now use rainwater throughout our home and very seldom have to change over to municipal water. We are extremely happy with the system and especially with Etienne's level of service and his expertise. He was recently back at our home to evaluate the system. We had been concerned about overflow from the system during periods of heavy rainfall. He quickly addressed and rectified the issue without problems.
Neil and Caroline S - Randpark, Randburg
Just wanted to say a very big thank you for installing our water harvesting system. We are really happy with the result and we are so blessed to be able to harvest rain water, connect it to our mains and even drink it during this drought crises. Your system has also gone a long way in significantly reducing our water bill (The difference from our November bill to our January bill was R2 000!!!). I must also compliment you and your team on your professionalism and great work ethic. Your work was very neat and tidy (a mess was never left behind) and the system is so easy to use. You certainly understand your product and gave us immense comfort that we had placed our water harvesting project in the right hands! Thumbs up to your enthusiasm and passion, you never made our project feel like just a job, it seemed to be a calling for you which makes all the difference - thank you! Wishing you all the very best.
Nicky and Mark C - Waterford Estate, Maroeladal, Johannesburg
As an engineer, I had a good idea what I wanted to make my home and business impervious to the regular interruptions in municipal water supply we seem to experience with increasing regularly. I was referred to Ettiene from Gratech and met with him on site. He made some cost efficient suggestions to improve my design. I was particularly pleased by his attitude. He did what he contracted to do quickly, efficiently and tidily and both systems worked perfectly from the moment they were commissioned. He finished on time and it was a pleasure to deal with him. I unreservedly recommend him for a hassle-free, competent service.
Lars F - Bryanston, Randburg
It was great to deal with a company, with such a hands on approach. Ettiene was very knowledgeable, and was able to advise us what we needed to fulfil our requirements. The installation was done, very neatly and with little disruption. It's wonderful to see how rain water is being harvested. Most of all we found Ettiene to be an honest, reliable and friendly person. I would highly recommend Gratech Water to anyone who needs their services.
Barbara R - Olivedale
I am very pleased with the prompt service I got for my relatively small job that Gratech fitted into their very busy schedule. Ettiene is a man of his word and always did what he said he was going to do. Ettiene's advice was spot-on. The workmanship excellent and now we have a 2,200 litre municipal backup water tank installed with automatic pressure pump as well as a rainwater tank - so we will be sorted when there are breaks in the municipal water supply. In future, as soon as I am in a position to do it, I plan to use Gratech to install a complete rainwater catchment-solution and grey water system at my house.
Stefaans D - Randpark, Randburg
Our complex is new and we felt that, in our later years, we would try to eliminate some of the more vexing problems like load-shedding by Eskom and water shortages by City of Jo'burg. As we had done with the electricity problem we wanted three quotations regarding a solution to our water situation. Etienne and his company Gratech Water were unknown to us but from the outset we were impressed by his approach to our needs. His quotation was competitive and his attention to us was excellent. We would have no hesitation in recommending him and his company to anyone who needs to solve their water storage problems.
Stella and Eric H - Bryanston, Randburg
We found Gratech to be very professional in our dealings with them. We were looking for a system to reduce our reliance on the municipal water supply, and also to help cut water costs. While we are waiting for the summer rains to assess the cost savings, the reduced reliance on municipal water has already been effective. The system was well specified, and installation done promptly and with the minimum of inconvenience - Gratech brought in a plumber, so we were only dealing with a single company, which is the best situation. After installation, Gratech popped in to ensure that all was working smoothly. We had a minor problem recently, and they came back to fix this up within the day that the problem was reported. We recommend Gratech as a company to deal with.
Leanne E - Riverclub, Sandton
Ettiene van der Merwe from Gratech installed a rainwater harvesting and filtration solution at our home in River Club - 10,000 litre water storage fully integrated into our water system. The installation took about 3 days and we are extremely satisfied with the result. Ettiene always returned emails or calls and came in on budget. I would recommend using Ettiene and Gratech.
Stuart E - Riverclub, Sandton
Hi Ettiene
Thanks again for you and your assistant's professional approach to our job - we enjoyed having you with us. Yes, it was really satisfying seeing our garden irrigation working so well with the rainwater!
Gill P - Saxonwold, Johannesburg

In searching for a supplier to fit a rain harvesting system, we were immediately attracted to Gratech through the well-presented, interesting and to the point website. Right from our first contact we felt we could trust you, and we were impressed with your presentation of the plans and the constructive ideas in improving to our initial thoughts. We were comforted by your courteous manner and the professional competence that you displayed given the time, and effort in interacting with us.

During the actual working period, our feelings were confirmed with your constant attention for detail, superior craftsmanship, and cleanliness, which meant that it has been a much more pleasant experience than we had anticipated. We would like to take this opportunity to thank you for a job well done. It was so nice not to have any worries or headaches, and we found your staff to be very courteous and competent, as well as being neat and tidy!

We are pleased to have come to know you and your company for delivering on promise, and we would be delighted to recommend you, Gratech, and your work to anyone who is interested, not only because of the professionalism that you exhibited in conducting your business, but also the enthusiasm that you show in taking on a challenge, and the pride you take in your work.

The work that you have done has made our home something to be proud of in terms of a small contribution to a sustainable world we live in. It was a treat to work with you and we wish you and Gratech nothing but success in the years to come!!

Joubert S - Greenside, Johannesburg
Delighted with our slimline tank.

GratechWater were extremely professional throughout the process. Good advice was given upfront and the installation was meticulous. Very happy with the solution provided and definitely seeing the benefits.

Dear Ettiene,
Just a small word of appreciation for the fabulous job you and your team did installing a 5000lt back-up tank system with pump and motor. When I called you I was in grave doubt about the efficacy of rain harvesting systems being a solution, due to the 'compound' nature of my dwellings i.e. lots of smaller buildings each with small roof size. At no time did you try to 'persuade' me to go a route that was inevitably going to be costly and not efficient. When you explained the 'back-up' system, I knew it was the right way to go, and felt relieved that I had a solution to what is an ongoing crisis, especially having tenants.
The job was done timeously and very neatly, and works perfectly.
Thank you for being such a gentleman and always explaining every part of the job. I have no hesitation recommending you for any water requirement system.
Irene M - Craighall Park
Hallo Ettiene
Jammer dat ek jou gemis het gister middag om jou te groet en persoonlik te bedank vir die UITSTEKENDE werk - en ook dat jy ons 'ingepas' het tussen die groot werk by die skole!!
Dit was regtig 'n plesier om jou te ontmoet en die werk deur GratechWater te laat doen en ek wens jou end Bev net die beste toe.
Beaulah S - Beverley Ext, Fourways
Just by the way we had 2 water outages in the last week in our estate and I did not even know - love the system!! Many thanks

Dear Ettiene
What a wonderful email to receive ! I am absolutely thrilled and cannot wait for the tanks to fill up and for Doris to feel the confident security that she has water. I told her that you said that once they were full and very heavy it would be pretty hard for anyone to load them onto a bakkie and steal them. She says the thefts are bad in Soweto!
My most heartfelt thanks to you for all you have done. It means so much to me that she is ok.
I look forward to meeting you some day.
Trish T - United Kingdom
Our new system is working beautifully!!
David L - Dunkeld
Hi Ettiene
This is a brief note to thank you for the water tank, pump and filter system we installed through Gratech Water early this month.
Before we agreed on a solution and installation began, I appreciated our thorough conversations to plan everything and help me understand my options. I always appreciate not being rushed into making a decision, especially where an investment is concerned.
You, Steven and Sabelo were incredibly professional and I was impressed with the hassle-free process once installation began. Your workmanship is very neat, effective and thorough.
Thanks too for following up to make sure everything is in perfect order.
Even before the rain fell, I could taste the difference in water quality from the mains, owing to the filtration system we've installed.
And then, two dummy runs and a real storm later, my 2500 litre tank was FULL! I switched off the main supply on the 20th of October and am thoroughly enjoying the satisfaction of knowing that my home is running on rain water - from the sky, to my roof, to the tank! Every load of washing makes me smile, as does every shower. And by the way, that pump is amazingly quiet. So the whole house has run off the JoJo Multislim for nearly a week now and with more rain expected, I have the sneaking suspicion we will want to install another at some point in the near future.
Thanks again - for a hugely positive experience all round!
Please use this as a letter of reference for anyone who is considering this investment. I can only recommend it - and your great service.
Yvette N - Parkhurst
