If you’re thinking about water storage or rain water harvesting, then ZimDam has the perfect solution for your needs.
They supply tanks and night storage dams for agricultural use and are fully equipped with an earth moving division capable of large storage system construction, trenching and land clearing where required. These tanks and ponds are mainly for irrigation and fish farming. For the mining industry they can install settling ponds as well as tailing ponds and dams.
ZimDam can provide storage tanks for manufacturing industries that are reliant on an uninterrupted water supply and they can also install rain water capture systems. A significant amount of rain water can be harvested from large warehouses and factories with big roofs.
ZimDam have worked with many of the schools in the country, both those based in Harare and those in remote areas. For the sporting and leisure industries ZimDam has supplied reservoirs and tanks for a number of different stadiums and sporting arenas, including the new cricket stadium being built in Victoria Falls. While in Victoria Falls, they have also done repairs to a leaking concrete reservoir for a large hotel and installed a fire tank in a new building complex there.
They even work on smaller residential projects like water features, streams and fish ponds. For garden projects they often work closely with landscapers and garden designers for the aesthetic appeal, the rocks and surroundings, and the planting. Many home owners are now installing rain water harvesting systems to see them through the dry periods.
The rain water harvesting systems are fitted with leaf filters to prevent leaves and other material from the roof entering the tank. ZimDam recommends that the water from the first rain of the season should be discarded if it is for domestic use as it washes all the dust off the roof – which you don’t want in your tank!
ZimDam has also been contracted to work on the Waste Management scheme at Pomona, where they are installing plastic liners to seal existing dumps – which will eventually be covered with additional landscaping on top.
They will also be installing two large plastic lined excavations where waste will be dumped in future without toxic chemicals leaching into the soil and the surrounding underground water table. These dump sites will be covered, and in time gas capture systems installed to harvest the usable gasses which are generated in the decomposition process.
They therefore have a vast and diversified portfolio from massive and complex projects for water storage and water harvesting, waste management, leisure and hospitality applications, down to smaller home gardens. Founded in 2014 they have many years of experience in wide range of different situations, and they are more than capable of meeting every challenge. The company office is based in Harare but they are in the process of establishing a new branch in Marondera for tank and reservoir assembly, which will employ an additional staff component. The company is a family business founded in 2014 by Mike and Mel Payne with their son Connor as the General Manager, so they have many years of experience in their field.
Their galvanised steel reservoirs are manufactured with a flat pack design allowing for easy transport and installation countrywide. They can be assembled quickly and easily and as they don’t need a concrete base they can be relocated with minimal fuss. Their suppliers for the panels conform to the SABS ISO 9001 standards and comply with standard engineering specifications. For customers’ peace of mind an engineering certificate can be provided.
The steel tanks are lined with polyester-net-reinforced P.V.C. with seams sealed by a welding process to provide watertight joints. The liner material can withstand exposure to a range of chemicals and the structures carry a 10-year warranty against faulty material or workmanship, with a life expectancy of an anticipated 25 years. Tanks are available in different sizes to store anything from 30,000 litres up to 4,000,000 litres in heights from 1,3 to 6,1 meters, so there’s always something to meet your requirements. The reservoirs can be fitted with either shade cloth or steel roofs to prevent leaves, insects and other debris from entering the water. The steel roofs are completely sealed so there’s no dust if the water is intended for drinking purposes.
Their earth dams utilise HDPE plastic sheeting which comes in thicknesses from 500 microns to 1,500 microns depending on the application. For special projects sheeting of 2,000 microns can be ordered. The liner comes in a 7-metre-wide roll that’s from 210 to 420 metres long. The rolls are extremely heavy so they are lifted into position by a crane and then manually rolled off and settled in place. The liner can be cut and joined to fit any configuration. Sheets of liner are joined by a special plastic welding process and ZimDam has a new spark tester to check and ensure that all the joins are correctly sealed so there’s no leakages or seeping. For earth dams ZimDam will excavate the depression and install steel water outlet pipes from 115mm to 400mm in diameter.
They can construct dams with smaller water storage capacity and larger dams that hold 20 million (or more) litres. They can also use the plastic liner to repair and seal older concrete reservoirs which might be cracked or leaking. So, for all your water storage, tanks, reservoirs and dams – as well as for water harvesting and domestic residential projects – Zim Dam are the leading local experts in the field.
