1 WATER AND WASTEWATER MANAGEMENT IN IMO STATE PRESENTED BY ISCA ENVIRONMENTAL AND PUBLIC UTILITIES COMMITTEE ENGR. NNAMDI D. AKAMNONU, P.E..CHAIR NZE CHINASA MADUMERE.PRESIDENT AT THE 9 TH. ANNUAL CONVENTION DAYTON, OHIO JULY 22, 2017

2 Water Usable water (Potable, Industrial, Commercial, Agriculture, Firefighting, Domestic cleaning)

3 What is portable water? Water fit for drinking or simply drinkable water How to get portable water for municipal use Deep wells Surface impound Desalinization

4 FACTS ON IMO WATER SUPPLY SYSTEM Study done in Imo state indicates there is no municipal water supply system. The government through its water cooperation, commissions discrete boreholes in different localities. These sources of water are often not continually checked for possible contaminants like bacteria and heavy metals.

5 FACTS ON IMO WATER SUPPLY SYSTEM Imo state initiated a standard water treatment facility at Otamiri Headworks in Owerri but abandoned it to rot. Imo state needs municipal water supply system in all major cities and towns through public water works team. This can be initiated as a capital project that will be paid with bond facility and the cost recouped from the rate payers. People will rather pay for clean, reliable and cheap water supply than the expensive and often contaminated private wells.

6 Wastewater What is wastewater? Water that has been used or run off from the ground surface

7 WASTEWATER TYPES Sanitary: Water discharged from the house hold after use. Storm: Surface Run-off after rain.

8 FACTS ABOUT IMO WASTEWATER Wastewater must be collected for treatment before final disposal Capital projects needed to collect and drain wastewater to a treatment or stabilization facility or site. Ponds are the quickest and most economical but not the safest way to dispose of wastewater. It will double as flood control mechanism to secure municipalities. Connections and collection are made by the aid of pipes, channels and bayous.

9 EROSION/FLOODING Water Erosion: This is the action that remove soil, rock or dissolved materials from one location on surface of the earth and then transport it away to another location. Water Flooding: This is when the volume of rain water falling does not drain away through the existing drainage systems or soak into the ground.

10 Erosion in Action

11 Flooding in Action City Flooding Due to size limitation, this video clip has be remove and will be sent on a separate cover Combined Erosion and Flooding Due to size limitation, this video clip has be remove and will be sent on a separate cover

12 Erosion Controls Build giant ponds (artificial lakes) near erosion prone areas. Construct engineered collection channels and canals to direct storm waters to ponds (lakes). On embankments, plant shrubs, grass and trees to check erosion. Never direct storm drains to water bodies.

13 Flooding Controls Build adequate storm water collection systems (pipes and gutters) to drain the locality. Plan for long range rain storm event (5 to 10 year storm) Build drain ponds (artificial lakes) at different areas outside city centers. Construct engineered collection channels and canals to direct storm waters to ponds (lakes). Never direct storm drains to water bodies.

14 CONCLUSION 1. NO WATER SUPPLY TO MEET DOMESTIC NEED, FIREFIGHTING PLUS INDUSTRIAL AND COMMERCIAL DEMAND. 2. NO PUBLIC WATER TREATMENT SYSTEM. 3. NO DISTRIBUTION NETWORK. 4. NO HOUSE CONNECTIONS. 5. NO PUBLIC TAP POINTS 6. CITIZENS/CONSUMERS NOT CONTRIBUTING TO THE COST OF WATER SUPPLY. 7. NO WATER STORAGE SYSTEMS 8. NO STAFFING

15 Recommendations: IN THE URBAN CENTERS (OWERRI,ORLU AND OKIGWE) 1. Need land water reservoirs (lakes) 2. Need deep boreholes as a backup 3. Need adequate supply of about 100 gallons per capita per day. 4. Need functional distribution network of trunk lines, arterial, and house connections 6. Need overhead storage tanks at strategic locations 7. Need adequate backup systems in power and pumps 8. Need metered rates 9. Need adequate staffing for 24-hour operation

16 Recommendations: IN SMALLER AND SPACED OUT TOWNS 1. Need deep boreholes 2. Need overhead storage tanks 3. Need network of trunk lines and arterials 4. Need public tap points at reasonable intervals 5. Need available power supply 6. Need backup systems of pumps and appurtenances 7. Need adequate staffing.
