The progress on the water project during the last three months focused on preparation of the site where the water tanks will be installed. The site by the Zambezi River was cleared and holes were dug for concrete footings that will support the steel scaffolding. A platform at the top of the scaffolding will hold four water tanks. The tanks, when full, will have an estimated weight of 160 tons. Because of the weight of the tanks, preparing a solid, strong base is critical. To ensure the concrete base is capable of supporting the weight of four full water tanks, eight concrete columns are supported by steel bar frames and are buried at a depth of 2 meters. A 150mm (6-inch) thick concrete slab connects all of the columns, providing stabilization and additional strength for the base. Both the concrete columns and the slab are cured to reach their maximum strength. Pictures of the steps involved in this process are attached to this report.
The construction of the steel scaffolding will commence as soon as the materials arrive in Mwandi. Once erected, the scaffolding will be topped by a steel platform and the tanks will be lifted to the platform using a crane. The tanks will be positioned for the best weight distribution and will be filled with water by a pump located at the river's edge. The pump will be able to fill the tanks in about 6 hours. The pumped water will be filtered for large particles before entering the tank and a UV filter will purify the water after it leaves the tanks and before it is delivered to the hospital.
If all goes well, the project will be completed by the end of January, 2020. Thanks to our generous donors, we have made great progress toward completing this project in less than a year! We look forward to sharing the pictures of a completed project in our next report.

First report on Solar Project Saves Lives
By Verna Case - Project Leader
We are actively working on creating a master plan for the entire hospital compound facility. The master plan will allow us to determine the extent of solar needs for all facilities that are currently part of the hospital and those facilities which we hope to add to the complex. We are currently considering a proposal submitted to the American Partners for developing a master plan that will accommodate the health care needs of the Western Province of Zambia for the next 20 years. This master plan will allow us to expand on the current solar resources that are now supplying the main hospital building. We have seen considerable savings on the hospital's ZESCO bills since the installation of the first phase of the solar project.

Water tanks in transport to Mwandi
The upgrade of reticulation system of pipes supplying the hospital with water is complete. Interestingly we discovered that the many of the old steel pipes that were replaced were first installed in 1930! So, it is not surprising that they weren’t efficiently delivering the needed water to the hospital buildings.
The bulk tank and treatment system were purchased in late July and have arrived in Mwandi from South Africa. The four large reservoirs will soon be elevated at the river’s edge on new steel pedestals which are now being constructed. Once the tanks are installed, the pump by the river will fill each tank. When full, the four tanks can hold enough water for two days of continuous use by the hospital, without the addition of more water. Because the elevation of the tanks will deliver water to the hospital without additional pumps and because of the tanks’ large capacity, the costs of pumping water to the hospital buildings will be greatly decreased.
By the time of our next report, we hope to have all tanks functioning and the new water treatment system installed. Pictures of the tanks being shipped and arriving in Mwandi are found below.
