Zimbabwe cholera outbreak snapshot 12Oct2018 def Page 1Feasibility Studies to determine the scope and extent of replacing existing sewage and water infrastructure in Harare, Zimbabwe, So as to allieviate the outbreaks of Cholera and Typhoid which occur too regularly.

Sun Earth Energy Ltd as preliminary project managers - 

Public Health Based Initiative – Based on Waste Collection, Sewage Systems and indirectly Water Supply

Based on the principles stated in the IWA [International Water Association] Wastewater Report 2018


Re-engineering of Harare Sewage Works, Sewage delivery infrastructures and refuse collection, to mitigate against pollution of water wells and the re-emergence of Cholera and Typhoid[1].


  • We need urgently an initial feasibility study undertaken and to be funded [Circa £450,000 – funds held in our escrow in UK – until technical and cost studies completed].
  • We need viability studies and cost studies – [included above] circa 5-9 months.
  • Humanitarian Funding Partners in the Far East will grant ultra long-term funding solutions via monthly stage payments to internationally recognised Civil Engineering Contractors/Project Managers – [to be approved by DFID] – contract payments made outside of Zimbabwe or RBZ systems to avoid corruption.
  • Fund application [above] subject to initial feasibilities studies initiated within 3-6 months.
  • Fund Approximations: [circa $2.3bn and/or subject to surveys above] 
  • New Sewage facility built in the environs of the current non-operational facility.
  • New Sewage distribution spine network and feeder network.
  • New refuse collection methodologies.
  • Integration of waste collection and sewage works into the same location[s].
  • Technical process to maximise methane production from blended organic refuse and sewage sludge [even use material from current non-functioning sewage works].
  • Small Combined Heat and Power [CHP[2]] at sewage works for on-site power, process heat/steam etc.
  • Surplus methane piped to CBD [or local business district?] for CHP[3] with cooling [Chilled Water Distribution]
  • Chilled Water Air Conditioning systems will reduce the demand on the electrical power generation capacity in Harare. Additional Power generation from the bio-methane will also help stabilise power supply situations in Harare as well.
  • Options to extend the scheme to Bulawayo and other cities.
