The end-to-end design of the Impact Pump “Series 0” launch product is complete and production quotations are being sourced. We are on schedule to launch our first product under the Impact Pumps brand in Kenya in late 2019. This coincides with our first million litres of water having been lifted in the field, directly improving the lives of rural communities through the provision of irrigation, drinking and sanitation services.
We have completed a number of accelerated ageing tests on a concept-design for our next generation of uDAHR prototype, that will be called the “Pre-Series 0” uDAHR. These included fatigue tests, corrosion tests, repeated dry-run tests and long-durations of operation in acidic silted wells with high chloride concentrations.
A new efficiency record has been set by our Bangladeshi Team in collaboration with IDE. Badrul Alam, treadle pump pioneer and leader of IDE’s technical centre in Dhaka, and his team, recorded a best ever hydraulic efficiency of 92% from a Pre-Series 0 Impact Pump installed at 27m depth (24m to water) at Miton, near Dhaka. This was achieved using steel pipework. The pump was driven by an Ennos Sunlight pump, manufactured under license in India by Jain Irrigation. The team also recorded efficiencies close to 90% using PVC pipework in place of HDPE.
As our gamma-uDAHR field trials progress in Kenya and Bangladesh, unexpected usage patterns continue to emerge. Although very different in nature and requirements, the distinction between water pumping for irrigation and domestic use (drinking/cooking and sanitation) is not always cut and dry in the real world. We now know that our well in Seme, Kenya is providing around 160 people with water for domestic use during the peak of the dry season, whilst being used for irrigation at other times. The daily pumped volumes required are similar, but continuity of supply is now even more essential. So far, users are very happy with the service that the uDAHR offers, as according to community leaders, existing powered-options (helical sumbersibles and suction pumps lowered on platforms) would often already have failed in a sandy dug well of varying water depth such as this.
Our Kenyan technical team managed by Futurepump Kenya have installed a Pre-Series 0 Impact Pump at GLAC primary school in Ahendu, Kisumu province, Kenya. This pump, driven by a Futurepump SF2, is providing an improved water supply for more than 250 children and staff from a water depth of 13m. Previously lifted by buckets, a key route for contamination of wells, the water is chlorinated prior to drinking.
Following an on-site demonstration to approximately 30 senior staff, and a successful 500 hour test result, we are pleased to announce that the Impact Pump has been selected for inclusion in the 2020 stock list of our main East African distribution partner. Our partner, who controls over 50% of the pump distribution market in East Africa, will take delivery of the first shipment of Impact Pumps via Mombasa in late 2019.
We are delighted to be able to announce that the Wellcome Trust have agreed to a further funding package of £1.45M to cover toolmaking, pilot production and launch across 8 East African countries. The extended project will run until August 2021, bridging a critical funding gap between applied research and commercial-sustainability.
Thermofluidics Engineers have installed our first deeper-well Pre-Series 0 Impact Pump at George Arombe’s family compound, Rabour, Kisumu province, Kenya. The pump is lifting water from a depth of 24m to serve a community of around 60 people. It is powered by a modified Futurepump SF2.
A treadle pump was spontaneously coupled to one of our gamma-uDAHRs in Kenya over the winter holiday period. This coincided with a minor breakage in the Futurepump SF2 drive pump during a time when no staff were on hand to fix the problem. The farmer reported good performance from the treadle-uDAHR combination, though said he was “looking forward” to having his solar pump working again!
Thermofluidics rebrands the uDAHR as “Impact Pump”, as it moves towards production readiness. The Impact Pump will be launched under the brand “Impact Pumps”.
