DAVIS Scc n tar G. A. Horstkotte, Jr., - General Manager -Chief Engineer SUBJECT: Sewer system improvements to correct deficiencies 1. BACKGROUND: Staff periodically reviews maintenance and operations records on existing sewers to determine their abilities to handle present and future loadings. When sufficient factual data exists to evaluate weak lines or portions of the system, corrective action as indicated by the combined studies of maintenance and engineering is recommended to the Board of Directors. 2. PURPOSE: To reduce long range maintenance costs, to avoid costly claims and to protect public health. 3. ALTERNATES: Postpone projects, pay claims and face Water Quality Control Board action and local complaints. 4. RECOMMENDATIONS: The following summary of projects is prepared on a priority need basis. These jobs will correct long-term deficiencies. We recommend authorization to prepare plans and specifications immediately for construction this summer. These preliminary estimates should be increased by 25%-35% to cover special contingencies. Funding will be from the Sewer Contruction Fund initially with recoveries as shown where watershed plans exist.

Horstkotte, Jr., - General Manager -Chief Engineer Nichols Claim 1. PROBLEM: Mrs. Nichols obtained a permit to connect a home at 311 Twin View Drive, Pleasant Hill to the District sewer system. The permit was issued for use of an existing lateral adjacent to the property, which District records indicated was not in service. She obtained permission from adjacent owners, paid District's fees and contracted for the installation with Tom Bristol for $440. When Bristol opened up the existing lateral, it was found to be in use and a more thorough search of District records found the con- nection permit. Bristol then had to install a new lateral for the Nichols' sewer and billed Mrs. Nichols $220 additional costs for this extra. Mrs. Nichols has requested an adjustment from the District in the amount of $220. 2. ALTERNATES: Refuse claim, compromise claim, or pay claim. 3. RECOMMENDATION: Pay claim. This additional cost of $220 seems to have been avoidable if District records had been accurate. Respectfully submitted: W. C. Dalton Administrative Engineer Recommendation Approved: G.
